About the 2023 wildfires in Hawaii, Governor Josh Green said, “For perspective, we’ve had six fire emergencies this August, we had six fire emergencies between 1953 and 2003. That’s how- how fast things are changing. I know that there is debate out there whether we should be talking about climate change or not. Well, let’s be real world, climate change is here we are in the midst of it with a hotter planet, and fiercer storms.”

Climate change is contributing to the increased intensity and frequency of wildfires through a combination of factors that create favorable conditions for wildfires to ignite, spread, and become more destructive. Here are some key ways in which climate change influences wildfires:

  1. Higher Temperatures:
    • Impact: Rising global temperatures increase the likelihood of extreme heat events.
    • Effect on Wildfires: Higher temperatures contribute to drier conditions, leading to increased evaporation and moisture loss from vegetation. Dry and hot conditions provide a more conducive environment for wildfires to ignite and spread.
  2. Drought Conditions:
    • Impact: Changes in precipitation patterns and prolonged droughts are linked to climate change.
    • Effect on Wildfires: Drought conditions result in dry vegetation, making it more susceptible to ignition. Reduced soil moisture levels also contribute to the flammability of ecosystems.
  3. Changing Rainfall Patterns:
    • Impact: Climate change alters regional rainfall patterns, leading to more intense rainfall in some areas and prolonged dry spells in others.
    • Effect on Wildfires: Areas experiencing reduced rainfall may face prolonged dry seasons, creating conditions favorable for wildfires. Intense rainfall in certain regions can lead to the growth of vegetation, which later dries out and becomes potential fuel for fires.
  4. Warming Winters:
    • Impact: Warmer winter temperatures can affect snowpack and contribute to earlier snowmelt.
    • Effect on Wildfires: Reduced snowpack and earlier snowmelt can result in drier soil and vegetation earlier in the year, extending the wildfire season and increasing the period of vulnerability to fire ignition.
  5. Extended Fire Season:
    • Impact: Changes in climate contribute to longer and more intense fire seasons.
    • Effect on Wildfires: A longer fire season means that conditions conducive to wildfires persist for a more extended period, increasing the likelihood of ignition and the potential for wildfires to become larger and more destructive.
  6. Insect Infestations:
    • Impact: Warmer temperatures allow for the proliferation of certain insects, such as bark beetles.
    • Effect on Wildfires: Insect-infested trees become more susceptible to disease and wildfire. Dead and dry trees contribute to the fuel load, increasing the intensity and spread of wildfires.
  7. Wind Patterns:
    • Impact: Changes in climate can influence wind patterns.
    • Effect on Wildfires: Changes in wind patterns can contribute to the rapid spread of wildfires. Strong winds can carry embers over long distances, leading to the ignition of new areas.
  8. Thawing Permafrost:
    • Impact: Warming temperatures contribute to the thawing of permafrost.
    • Effect on Wildfires: Thawing permafrost releases stored carbon, creating flammable conditions. It can also lead to changes in vegetation types, altering fuel availability for wildfires.

The combination of these factors creates a feedback loops, where more intense and frequent wildfires release large amounts of carbon dioxide into the atmosphere, contributing to further climate change. This cycle reinforces the importance of addressing both the causes and consequences of climate change to mitigate the impact on wildfire risk. While the beautiful sunsets during forest fires create captivating visuals, it’s essential to recognize the environmental and health impacts associated with wildfires. Wildfires can cause significant damage to ecosystems, contribute to air pollution, and pose risks to human health. The mesmerizing sunsets are a visible reminder of the interconnectedness of atmospheric processes and the far-reaching effects of natural events like wildfires.

In addition to the carbon feedback loop (the carbon emissions of Canada’s fires outweighed the combined emissions from its oil and gas, transport and agriculture sectors), the fires also cause the melting of the permafrost and zombie fires to burn in the permafrost. The permafrost collapse is a self-sustaining feedback loop/tipping point. As the permafrost melts, the peatlands emit CO2 and methane. The increase in CO2 and methane results in more warming that results in more peatland emissions. A third feedback loop is created with lightning strikes. The study Forests at Risk Due to Lightning Fires found a sensitivity of extratropical intact forests to potential increases in lightning fires, which would have far-reaching consequences for terrestrial carbon storage and biodiversity. The results show that, on a global scale, lightning is the primary ignition source of fires in temperate and boreal forests. Global warming causes more extreme weather events and conditions for lightning creating more forest fires that create more warming and more lightning strikes.

The study Wildfire as a major driver of recent permafrost thaw in boreal peatlands published in the Journal Nature Communications found wildfires have caused a quarter of permafrost thaw (2,000 square kilometres) in Western Canada’s boreal peatlands over the past 30 years. “Historically, permafrost in this area underwent a natural cycle of thawing and reforming, but given current climate conditions and projections for the future, this fire-induced thaw appears to be irreversible,” said Carolyn Gibson, who conducted the research.

On January 1, 2024, the article, Why Are Alaska’s Rivers Turning Orange?, was published in Scientific America. “Streams in Alaska are turning orange with iron and sulfuric acid. Scientists who have studied these rusting rivers agree that the ultimate cause is climate change. Kobuk Valley National Park has warmed by 2.4 degrees Celsius (4.32 degrees Fahrenheit) since 2006 and could get another 10.2 degrees C hotter by 2100, a greater increase than projected for any other national park. The heat may already have begun to thaw 40 percent of the park’s permafrost, the layer of earth just under the topsoil that normally remains frozen year-round. McPhee wanted to protect the Salmon River because humans had ‘not yet begun to change it.’ Now, less than 50 years later, we have done just that. The last great wilderness in America, which by law is supposed to be ‘untrammeled by man,’ is being trammeled from afar by our global emissions.”

NASA reported: Wildland fire experts have described Canada’s 2023 fire season as record-breaking and shocking. Over the course of a fire season that started early and ended late, blazes have burned an estimated 18.4 million hectares. Hundreds of fires exceeded 10,000 hectares (39 square miles), large enough to be considered “megafires.” These megafires were also unusually widespread this season, charring forests from British Columbia and Alberta in the west to Quebec and the Atlantic provinces in the east to the Northwest Territories and the Yukon in the north.

Though the rate of change in climate disasters’ intensity, duration, and likelihood vary according to the type of extreme weather, a “rule-of-thumb” can be derived from the Canada wildfires of 2023. The World Weather Attribution Organization found, “Climate change made the cumulative severity of Quebec’s 2023 fire season to the end of July around 50% more intense, and seasons of this severity at least seven times more likely to occur.”

50% more intense
7 x more likely

Sidd said, “Do you remember back in the early 2000’s when we thought we wouldn’t live to see the extreme changes due to global warming?”

Daniel replied, “I think 2023 is the most significant year so far. We saw confirmation of tipping points being crossed for Mountain Glacier Loss, Greenland Ice Sheet Collapse, Antarctic Ice Sheet Collapse, and potentially the Collapse of AMOC.”

Sidd continued, “We already knew that. It was Canada catching on fire that I could not believe. I never thought I’d live to see the day.”

Daniel asked, “Do you think the permafrost and peatlands will have zombie fires and cause the permafrost tipping point?”

Sidd responded, “Yes. They are gone, too. We already know from the permafrost peatland fires in Siberia.”

Daniel ponders, “Hmmmm… I guess that means my plan went up in smoke? My worst case scenario / last resort emergency plan was to escape to Canada.”

Posted on by admin

By Daniel Brouse and Sidd Mukherjee

Climate change poses risks to real estate in the United States in various ways, and these risks can affect property values, insurance costs, and overall property resilience. Here are some ways in which all US real estate is at risk from climate change:

  1. Sea Level Rise and Coastal Properties:
    • Coastal properties are particularly vulnerable to sea level rise, storm surges, and coastal erosion. As sea levels continue to rise due to global warming, properties near coastlines may experience increased flooding and damage from more frequent and severe storms. Storm surges in Florida are an example.
  2. Extreme Weather Events:
    • Climate change is contributing to an increase in the frequency and intensity of extreme weather events, such as hurricanes, wildfires, floods, and droughts. Properties in regions prone to these events are at risk of damage, destruction, and increased insurance costs.
  3. Temperature Extremes:
    • Rising temperatures can lead to more frequent and prolonged heatwaves, affecting property infrastructure, energy demand, and potentially decreasing property values in areas with extreme heat.
  4. Changes in Precipitation Patterns:
    • Changes in precipitation patterns, including increased violent rainfall or prolonged droughts, can impact properties by causing flooding, landslides, or water scarcity. These changes may affect property values and increase maintenance costs.
  5. Wildfires:
    • Increased temperatures and changing precipitation patterns contribute to the risk of wildfires. Properties in wildfire-prone areas face threats to both their physical structures and the surrounding environment.
  6. Homeowners and Flood Insurance Costs:
    • Flood insurance will become expensive and difficult to obtain. Climate-related risks can lead to higher insurance premiums and deductibles, particularly in high-risk areas. As the frequency and severity of climate-related events increase, insurance companies may reassess risk models and adjust pricing accordingly.
  7. Infrastructure Vulnerability:
    • Climate change can impact infrastructure such as roads, bridges, and utilities. Properties relying on vulnerable infrastructure may face challenges related to accessibility, reliability, and potential increases in repair and maintenance costs.
  8. Health Risks:
    • Humans will experience greater loss and damage to life and quality of life from air pollution, decreasing supply of potable water, extreme weather events, and disease. The greatest short term climate change risk to human health is deadly humid heat (wet-bulb temperature). Climate change can affect human health, and properties in areas prone to heatwaves, air pollution, or vector-borne diseases may face increased health risks. This could influence property values and community desirability.Almost all survivors of climate-related disasters suffer from mental distress. Of those who have not experienced climate disasters, more than two-thirds of U.S. adults (68%) have reported climate change anxiety.
  9. Regulatory Changes:
    • Governments may implement stricter building codes, zoning regulations, and disclosure requirements related to climate-related risks. Non-compliance could affect property values and lead to increased costs for property owners. Loss and damage litigation against oil companies and governments will change world economics.
  10. Shifts in Property Demand:

It’s important to note that the degree of risk varies by region and property type. Some areas may experience more immediate and severe impacts, while others may be more resilient. Assessing and mitigating these risks require a comprehensive understanding of local climate vulnerabilities and the implementation of strategies to enhance property resilience. Policymakers, real estate professionals, and property owners are increasingly recognizing the importance of addressing climate risks to ensure the long-term sustainability and value of real estate assets. Thus, our recommendation to evacuate Florida now (i.e. Managed Retreat).

bookmark_borderChaos Theory: Soil, Atmosphere and Ocean Interaction With Thermal Energy and Carbon Storage

Posted on by admin

by Daniel Brouse

Chaos theory emphasizes the complexity and nonlinearity of dynamic systems, and this complexity is inherent in the interactions between soil, atmosphere, and oceans in the Earth’s climate system. Here’s how these components interact with thermal energy and carbon storage:

Soil-Atmosphere Interaction:

  1. Thermal Energy Exchange:
    • Soil plays a crucial role in the exchange of thermal energy with the atmosphere. The temperature of the soil surface affects the transfer of heat to the atmosphere through processes such as conduction and convection. The thermal properties of soil, including its composition and moisture content, influence this energy exchange.
  2. Carbon Storage and Cycling:
    • Soil acts as a reservoir for carbon in the form of organic matter. This carbon storage is dynamic and involves complex interactions between plants, microorganisms, and the soil matrix. Soil organic carbon contributes to the global carbon cycle, affecting atmospheric CO2 concentrations.
  3. Feedback Mechanisms:
    • Nonlinear feedback mechanisms between soil and atmosphere can influence climate dynamics. For example, changes in temperature and precipitation patterns may impact soil moisture, affecting vegetation growth and altering the surface energy balance.

Soil-Ocean Interaction:

  1. Carbon Storage and Sequestration:
    • Oceans play a crucial role in global carbon storage. Dissolved carbon dioxide is absorbed by the ocean, forming carbonic acid. Additionally, organic matter from marine life contributes to carbon storage in ocean sediments. The exchange of carbon between soil and oceans is interconnected and can influence atmospheric CO2 levels.
  2. Thermal Inertia:
    • Oceans have a high thermal inertia, meaning they can absorb and store large amounts of heat. This property moderates temperature extremes, influencing atmospheric temperature patterns. Changes in ocean temperatures can, in turn, impact regional and global climate dynamics.
  3. Ocean Circulation and Climate:
    • Ocean circulation patterns, such as the Atlantic Meridional Overturning Circulation (AMOC), play a role in redistributing heat around the globe. Changes in ocean circulation can have cascading effects on atmospheric circulation patterns, influencing climate on a large scale.

Atmosphere-Soil-Ocean Coupling:

  1. Teleconnections:
    • Chaos theory recognizes the concept of teleconnections, where seemingly unrelated events in one part of the Earth system influence conditions in another. For instance, changes in sea surface temperatures (linked to ocean dynamics) can affect atmospheric circulation patterns, leading to variations in precipitation and temperature on land.
  2. Climate Variability:
    • The complex interactions between soil, atmosphere, and oceans contribute to climate variability. Chaos theory helps to understand the sensitivity of the climate system to initial conditions and how small perturbations in one component can lead to significant and sometimes unpredictable outcomes.

In summary, chaos theory underscores the intricate, nonlinear, and interconnected nature of the relationships between soil, atmosphere, and oceans in the context of thermal energy and carbon storage. These interactions contribute to the Earth’s climate system’s complexity, and understanding these dynamics is crucial for accurately modeling and predicting climate changes. Ongoing research and improved modeling techniques aim to enhance our understanding of these complex interactions and their implications for climate variability and change.

Posted on by admin

Why is soil integral to climate change? How does soil degradation lead to desertification?

Soil plays a crucial role in climate change mitigation and adaptation, and soil degradation can contribute to the process of desertification. Here’s why soil is integral to climate change and how soil degradation can lead to desertification:

Importance of Soil in Climate Change:

  1. Carbon Sequestration:
    • Healthy soils act as a significant carbon sink, storing large amounts of carbon in the form of organic matter. This process, known as carbon sequestration, helps mitigate climate change by reducing the concentration of greenhouse gases, particularly carbon dioxide (CO2), in the atmosphere.
  2. Water Regulation:
    • Soil influences water availability and regulates the water cycle. Healthy soils absorb and store water, reducing the risk of floods and contributing to moisture availability during dry periods. This capacity for water regulation is crucial for climate resilience.
  3. Biodiversity Support:
    • Healthy soils provide habitat and support for a diverse range of organisms, including bacteria, fungi, insects, and plant roots. Biodiversity in the soil contributes to ecosystem stability, resilience, and adaptation to changing environmental conditions.
  4. Nutrient Cycling:
    • Soil is essential for nutrient cycling, as it hosts microbial communities that break down organic matter and make nutrients available to plants. This nutrient cycling supports plant growth and contributes to overall ecosystem health.

Soil Degradation and Desertification:

  1. Erosion:
    • Soil degradation, often caused by factors like deforestation, overgrazing, and unsustainable agricultural practices, can lead to increased soil erosion. Erosion removes the topsoil layer, which is rich in organic matter and nutrients, reducing the soil’s fertility and water retention capacity.
  2. Loss of Soil Structure:
    • Poor land management practices, such as excessive plowing, deforestation, and improper irrigation, can lead to the loss of soil structure. This makes the soil more susceptible to erosion, reduces water infiltration, and hinders the growth of vegetation.
  3. Decreased Carbon Sequestration:
    • Soil degradation results in the loss of organic matter, reducing the soil’s ability to sequester carbon. This can contribute to increased atmospheric CO2 levels, exacerbating the greenhouse effect and climate change.
  4. Loss of Biodiversity:
    • Degraded soils often experience a decline in microbial and plant diversity. This loss of biodiversity weakens the soil’s resilience to environmental stresses and reduces its capacity to support healthy ecosystems.
  5. Increased Vulnerability to Climate Change:
    • Degraded soils are more vulnerable to the impacts of climate change, such as extreme weather events, droughts, and temperature variations. This vulnerability can create a feedback loop, where climate change further exacerbates soil degradation.
  6. Desertification:
    • Desertification is the process by which fertile land becomes increasingly arid and unproductive, eventually turning into desert-like conditions. Soil degradation, through erosion, loss of organic matter, and reduced water retention, is a key driver of desertification.
  7. Impact on Livelihoods:
    • Desertification poses a threat to agricultural productivity, water resources, and local livelihoods. It can lead to the displacement of communities and exacerbate social and economic challenges, contributing to a cycle of poverty and environmental degradation.

Addressing soil degradation is crucial for sustainable land management, climate change mitigation, and the prevention of desertification. Implementing conservation practices, agroforestry, reforestation, and sustainable agriculture techniques can help restore and protect soils, contributing to climate resilience and biodiversity conservation.

Soil is integral to our climate.

What are the best methods to mitigate against climate change by providing wind breaks, shade, moisture retention, and climate control, around my home, as well as prevent soil degradation and desertification?

Creating a sustainable and climate-resilient environment around your home involves a combination of practices that address wind breaks, shade, moisture retention, climate control, and prevention of soil degradation. Here are some effective methods:

  1. Planting Trees and Vegetation:
    • Wind Breaks and Shade: Planting windbreaks, such as rows of trees or shrubs, can protect your home from strong winds and provide shade. Deciduous trees strategically placed on the south and west sides of your home can offer shade during hot seasons while allowing sunlight through during colder seasons.
    • Moisture Retention: Trees and vegetation help retain moisture in the soil by reducing evaporation. Mulching around plants and trees further aids in moisture retention.
    • Climate Control: Trees act as natural air conditioners, cooling the surrounding environment through a process called transpiration. This can contribute to a more comfortable microclimate around your home.
  2. Rainwater Harvesting:
    • Install rain barrels or cisterns to collect rainwater. This harvested water can be used for watering plants, reducing the need for additional irrigation and helping with moisture retention in the soil.
  3. Appropriate Plant Selection:
    • Choose native or drought-resistant plants that are well-suited to your local climate. These plants typically require less water, contribute to soil stability, and are more resilient in the face of climate variability.
  4. Contour Planting and Terracing:
    • Contour planting involves planting along the contour lines of the land to slow down water runoff, promoting infiltration and reducing soil erosion. Terracing is another method to control water runoff on sloped terrain.
  5. Ground Cover and Cover Crops:
    • Planting ground cover or cover crops helps prevent soil erosion, improves moisture retention, and contributes to overall soil health. These plants protect the soil surface from the impact of raindrops and enhance soil structure.
  6. Permeable Surfaces:
    • Use permeable surfaces, such as permeable pavers or gravel, in areas around your home. This allows rainwater to infiltrate into the soil rather than running off, contributing to soil moisture and preventing erosion.
  7. Composting:
    • Implement composting practices to improve soil structure and fertility. Healthy soils are more resistant to erosion, and they can retain moisture better, promoting plant growth.
  8. Integrated Pest Management (IPM):
    • Practice IPM techniques to manage pests without resorting to excessive use of pesticides. Healthy ecosystems are more resilient to climate stresses, and minimizing chemical inputs helps maintain biodiversity and soil health.
  9. Microclimate Planning:
    • Plan your landscaping to create microclimates around your home. For example, placing hard surfaces like rocks or pavement near the home can absorb and release heat, contributing to temperature regulation.
  10. Educate and Involve the Community:
  • Collaborate with neighbors and community members to implement sustainable practices collectively. Building awareness and working together can have a more significant impact on preventing soil degradation and desertification.

By integrating these practices, you can contribute to a more sustainable and climate-resilient environment around your home while mitigating the impacts of climate change and promoting soil health.

January 9, 2024

Human induced climate change is an exponential component of an unordered system (chaos theory). That means global warming is accelerating at a rapid rate in a complex way.

Unfortunately, even scientists are failing to see (let alone forecast) the rapid acceleration in climate change. Due to their complexity, the impacts of the Domino Effect are being underestimated. Tipping points are Critical Milestones that directly impact the rate of acceleration in climate change by multiplying the number and intensity of feedback loops. The Domino Effect is also known as “tipping cascades” in climate science. Cascading impacts in relation to tipping points include cascading impacts across biogeophysical and social systems. Until recently, scientist have been drastically underestimating the social-ecological systems. The University of Exeter reports, “There is a notable lack of topic clusters dedicated to how humans will be impacted by climate-related tipping cascades.”

The Age of Loss and Damage is a new way of thinking about economics by combining economics, climate science, statistics, and physics. Until now, economic models have been unfit to capture the full extent of climate damage. Traditionally, “integrated assessment models” (IAMs) were used to forecast “shock” events. IAMs use “quadratic function” to calculate GDP losses by squaring the temperature change, yet ignore other methods (such as the exponential function) that are better suited for rapid change. “Climate change is fundamentally different to other shocks because once it has hit, it doesn’t go away,” said Thierry Philipponnat, author of a report by Finance Watch, a Brussels-based public interest NGO on financial issues. “And if the fundamental assumption is flawed, all the rest makes little sense — if any.”

Reuters reported, “Critics say this (IAMs) choice is doomed to underplay the likely impact – particularly if the planet hits environmental tipping points in which damage is not only irreversible but happens at an ever-accelerating rate.” Thierry Philipponnat’s report, Finance in a Hot House World, concludes: “Climate risk is growing to disruptive levels throughout the financial system and the guardians of financial stability urgently need to adapt their tools to regain control.” The report calls for economic models that do not mislead, scenario analyses that prepare the market, and a new prudential tool to address the build-up of systemic climate risk.

Traditional economics is based upon the “costs and benefits” to society. Since there are no known long-term benefits of climate change to society, the Age of Loss and Damage economics focuses on the exponential costs of climate change to society.
— from The Age of Loss and Damage / Brouse (2023)

2023: The Hottest Year in Human History
2023 was a wake-up call to both biogeophysical and social-ecological scientists. The record breaking physical and economical impacts could be felt worldwide. The record warming year was seventeen times greater than any other record increase in history. Typically record breaking temperatures are measured in 100th degrees. There were also 200 consecutive days of record breaking temperatures. Typically there are one or two record breaking days in row. The increase in intensity and frequency of record breaking heat requires forecasting models to be recast.

2023 Biogeophysical Records

Global temperatures reached exceptionally high levels in 2023. The Copernicus Climate Change Service (C3S), implemented by the European Centre for Medium-Range Weather Forecasts on behalf of the European Commission with funding from the EU, monitored several key climate indicators throughout the year, reporting on record-breaking conditions such as the hottest month on record and daily global temperature averages briefly surpassing pre-industrial levels by more than 2°C. Unprecedented global temperatures from June onwards led 2023 to become the warmest year on record – overtaking by a large margin 2016, the previous warmest year.

Highlights: 

  • 2023 is confirmed as the warmest calendar year in global temperature data records going back to 1850
  • 2023 had a global average temperature of 14.98°C, 0.17°C higher than the previous highest annual value in 2016
  • 2023 was 0.60°C warmer than the 1991-2020 average and 1.48°C warmer than the 1850-1900 pre-industrial level
  • It is likely that a 12-month period ending in January or February 2024 will exceed 1.5°C above the pre-industrial level
  • 2023 marks the first time on record that every day within a year has exceeded 1°C above the 1850-1900 pre-industrial level. Close to 50% of days were more than 1.5°C warmer then the 1850-1900 level, and two days in November were, for the first time, more than 2°C warmer.
  • Annual average air temperatures were the warmest on record, or close to the warmest, over sizeable parts of all ocean basins and all continents except Australia
  • Each month from June to December in 2023 was warmer than the corresponding month in any previous year
  • July and August 2023 were the warmest two months on record. Boreal summer (June-August) was also the warmest season on record
  • September 2023 was the month with a temperature deviation above the 1991–2020 average larger than any month in the ERA5 dataset
  • December 2023 was the warmest December on record globally, with an average temperature of 13.51°C, 0.85°C above the 1991-2020 average and 1.78°C above the 1850-1900 level for the month. You can access information specific for December 2023 in our monthly bulletin
  • Global average sea surface temperatures (SSTs) remained persistently and unusually high, reaching record levels for the time of year from April through December
  • 2023 saw a transition to El Niño. In spring 2023, La Niña came to an end and El Niño conditions began to develop, with the WMO declaring the onset of El Niño in early July.
  • High SSTs in most ocean basins, and in particular in the North Atlantic, played an important role in the record-breaking global SSTs
  • The unprecedented SSTs were associated with marine heatwaves around the globe, including in parts of the Mediterranean, Gulf of Mexico and the Caribbean, Indian Ocean and North Pacific, and much of the North Atlantic
  • 2023 was remarkable for Antarctic sea ice: it reached record low extents for the corresponding time of the year in 8 months. Both the daily and monthly extents reached all-time minima in February 2023
  • Arctic sea ice extent at its annual peak in March ranked amongst the four lowest for the time of the year in the satellite record. The annual minimum in September was the sixth-lowest
  • The atmospheric concentrations of carbon dioxide and methane continued to increase and reached record levels in 2023, reaching 419 ppm and 1902 ppb respectively. Carbon dioxide concentrations in 2023 were 2.4 ppm higher than in 2022 and methane concentrations increased by 11 ppb.
  • A large number of extreme events were recorded across the globe, including heatwaves, floods, droughts and wildfires. Estimated global wildfire carbon emissions in 2023 increased by 30% with respect to 2022 driven largely by persistent wildfires in Canada

2023 Social-Ecological Records

NOAA: 2023 A historic year of U.S. billion-dollar weather and climate disasters

In 2023, the U.S. experienced 28 separate weather and climate disasters costing at least 1 billion dollars. That number puts 2023 into first place for the highest number of billion-dollar disasters in a calendar year and included:

  • 1 winter storm/cold wave event (across the northeast U.S. in early-February).
  • 1 wildfire event (firestorm destroying town of Lahaina on Maui Island of Hawaii).
  • 1 drought and heat wave event (focused across the central and southern U.S.).
  • 4 flooding events (in California, Florida, and across the eastern and northeastern U.S.).
  • 2 tornado outbreaks (across the central and eastern U.S.).
  • 2 tropical cyclones (Idalia in Florida and Typhoon Mawar in Guam).
  • 17 severe weather/hail events (across many parts of the country).

2023 was also deadly, causing at least 492 direct or indirect fatalities — the 8th most disaster-related fatalities for the contiguous U.S. since 1980.

What Can I Do?
There are plenty of things you can do to help save the planet. Stop using fossil fuels. Consume less. Love more. Here is a list of additional actions you can take.

Posted on by admin

by Daniel Brouse and Sidd Mukherjess

In general, the coasts that are seeing the largest storm surges are the same areas that are experiencing the fastest rate of sea level rise. The sea level does not rise at the same rate for most coastlines. Some of the conditions that determine the sea level at any given location include: water temperature (thermal expansion), circulation, ocean floor contour, ice melt, ocean dynamics, and Earth’s uneven gravity field.

Idalia Storm Surge 2023
Idalia Storm Surge 2023

The Shape of Things to Come
For the foreseeable future, storm surges will offer a good forecast of future sea level rise. Hurricane Idalia’s storm surge (pictured / 2023), brought a 10-15 storm surge to the northern coast of Florida. In 2022, Hurricane Ida brought a 14-20 foot storm surge to the southern coast of Florida. Ida also made landfall in Southeastern USA. Plaquemines Parish on the east bank of the Mississippi River had an estimated storm surge of at least 14 feet. Grand Isle, Louisiana, which was located just east of the landfall, was struck by 10.2 feet and rendered uninhabitable after the storm.

We know these areas of the United States will see sea levels rise at least 10-15 feet because it has already happened. Although it was only for hours, you wouldn’t want to live there during those hours. Not to mention, the frequency of these extreme weather events is rising exponentially. Thus, our recommendation to evacuate Florida now (i.e. Managed Retreat.) The billions of dollars spent to rebuild after Hurricane Ida will all be for naught. Allowing building will needlessly endanger property and lives. Parts of the world have already seen storm surges of 40 feet. I expect most North American coastlines will see sea levels rise, if only temporarily, by 20-40 feet this century. Within a generation, these areas could be submerged most of the time.

Don’t Be Fooled by Relative Variations
The level of the oceans is rising; however, some climate change deniers may try to claim that sea level is receding. Yes, in some instances certain areas will see a decline in the relative sea level. As ice melt accelerates, gravity and glacial isostatic adjustment will have a greater impact on where the sea level rises the most. Greenland is a good example. Greenland has one of the largest land ice sheets. You might think the sea would rise the fastest closest to the melt. “Greenland is like a bowl with large cracks in its sides.” The giant ice mass has sunk the ground, as well as, added a huge mass on top of it. Much of Greenland’s ice melt is just kind-of hanging out in the bowl. Two things are happening to change that:
1) As the ice mass melts, it exerts less gravitational pull on the surrounding water and the water gets pulled toward the equator.
2) At the same time, the Earth is rebounding under the bowl as the mass moves away. Much will depend on the extent and speed of the rebound. Though we don’t know how fast the rebound will happen, NASA has a satellite program gathering better data by measuring the gravitational pull on the satellite (GRACE Tellus Gravity Recovery & Climate Experiment).

At the same time that Greenland is “rising”, many cities are sinking. Alexandria, Amsterdam, Bangkok, Charleston, Miami, New Orleans, New York, Chicago, and Norfolk are all “caving in.” Houston is the 10th-fastest sinking city in the world, and the U.S. city sinking the fastest.

Sidd added, “As the ice melts off Greenland, sea level will rise around Antarctica and drop around Greenland, and as the ice melts in Antarctica, sea will rise around Greenland and drop around Antarctica. In general, sea levels fall where the ice is melting and rise on the other side of the world. There is a small effect on earth rotation and polar direction, but not enough to worry about.”

Measuring Sea Level Rise
So, one of the biggest questions in the future is how do you measure sea level rise? From where the land was pre-industrial, where the land is today, or where the land is tomorrow? In any event, the Earth crossed tipping points which make extreme sea level rise inevitable and irreversible. Planners should plan on it.

Sidd reiterated, “That 270 feet of sea level rise will take a long time. I would be more careful about the violent rain than the ice melt.”

COVID=19

Long-COVID, or post-infection COVID, appears to affect the majority of the population. For individuals that “recover” from COVID-19, they can expect a decreased quality of life and a premature death.

Decrease in Quality of Life
Known chronic conditions resulting from a COVID infection include: Permanent Organ Damage, Persistent SARS-CoV-2 RNA in multiple organs and throughout the brain, Destruction of Good Gut Bacteria Resulting in a Compromised Immune System, Epigenetic Modifications (Changes to DNA), Change in Cell Fate, Tryptophan Deficiency, Dysfunctional Kynurenine Pathway, Neurological Damage, New-Onset Alzheimer’s Disease, Exertional Intolerance, Oxygen Extraction, Reduced Exercise Capacity, Down Regulating NAD+, Up Regulating IDO, Rogue Antibodies, Insulin Reduction, Diabetes, High Cholesterol, Heart Disease and Stroke, Increased Risk of Cancer, Blood Clots, Hypertension, Vascular Disorders, Myocarditis and Heart Disease, Multisystem Inflammatory Syndrome in Children (MIS-C), and Dysregulation of the innate immune system, i.e. “cytokine storm”.

Decrease in Life Expectancy
In epidemiology, the excess deaths or excess mortality is a measure of the increase in the number deaths.

On October 26, 2023, Insurance News Network reported, “Excess mortality is the difference between the total number of deaths for a specific time period and the number that would have been expected. The numbers were naturally forecast to climb during the pandemic, but some industry and health authorities are concerned the rates haven’t greatly diminished as COVID infection rates have declined.”

In November of 2023, the SOA Research Group released Group Life COVID-19 Mortality Survey Report finding the 39-month period of April 2020 through June 2023 showed the following Group Life mortality results:
• Estimated reported Group Life claim incidence rates were up 13.2% on a seasonally-adjusted basis compared to 2017–2019 reported claims.
• Estimated incurred Group Life incidence rates were 12.2% higher than baseline on a seasonally-adjusted basis. As noted above, the incurred incidence rates in May and June 2023 are based on fairly incomplete data, so they are subject to change and should not be fully relied upon at this point.

90% of these excess deaths were caused by post-COVID conditions. 10% of the excess deaths are attributed to the COVID virus.

A Boston University study identified a total of 1,179,024 excess deaths from March 2020 through February 2022, including an estimated 634,830 excess deaths from March 2020 to February 2021, and 544,194 estimated excess deaths from March 2021 to February 2022.

Causes
A decrease in life expectancy, quality of life, or death after a COVID infection is usually caused by complications from the infection, persistent virus (chronic infection), and/or epigenetic changes.

As the Earth warms, the air will hold more moisture. More moisture-laden air moves over land and creates atmospheric rivers (Pineapple Express). The Journal EOS in the article Atmospheric Rivers Spur High-Tide Floods on U.S. West Coast said, “Atmospheric rivers are narrow bands of moisture that travel across the lower troposphere, generally at the leading edges of massive low-pressure systems. At their peak, they can carry as much water through the sky as the Amazon River does on land. They unleash intense winds and heavy rain as they surge across the Pacific Ocean, eventually making landfall on the U.S. West Coast, contributing to many high-tide flooding events.”

The atmospheric rivers also bring heavy rainfall inland causing extreme flooding. In October of 2021 NOAA said, “a convergence of storms brought more than half a foot of rain to parts of the Bay area in addition to strong winds, flash floods, and mud/landslides. They also bring the potential for heavy snow to higher elevations in the Sierra Nevada mountain range.” (Atmospheric River Hits the West Coast)

In December 2022 and January 2023, California experienced nine back-to-back atmospheric rivers; the longest stretch of continuous atmospheric river conditions on record. NOAA went on to report, “Several atmospheric rivers struck in March 2023, bringing heavy rain and snowfall to much of the West. According to the California Department of Water Resources, the statewide snowpack was among the deepest ever recorded for the end of March — 237% of normal.”

In October of 2023, a tropical storm turned into category 5 Hurricane Otis in a record 12-hour intensification. Hurricane expert Kerry Emanual said Otis was supercharged by global warming. Historically, hurricanes’ intensification was driven by ocean surface temperatures. Otis was additionally supercharged by increasing temperatures deeper in the ocean. Hurricane Otis became the strongest on record to hit Mexico’s Pacific coast. NOAA reported, “When Otis first hit, mudslides outside the city in mountainous terrain prevented crews from traveling to the city to provide aid, and according to the Associated Press, the 10,000 troops that were deployed to the area lacked the tools needed to clear mud and downed trees off roads.”
