Climate change will eventually cause most American’s real estate to become worthless and uninhabitable.

“Currently, we have crossed the tipping point when human induced climate change triggers a chain reaction of feedback loops. The Earth will exceed 1.5 degrees Celsius (average global surface temperature over the surface of the earth for ten years) by the 2040’s and a societal collapse will ensue. For the most part, the Earth will be uninhabitable for humans by 2070 UNLESS immediate action is taken.” — Daniel Brouse and Sidd Mukherjee (climate scientists)

In an article entitled “A safer haven? How the Midwest can be a refuge amid climate change—if we prepare” the Detroit Business Journal reports:

In the early 21st century, global climate change is spawning a new kind of migrant to the Upper Midwest: “Climigrants” seeking refuge from the forest fires of Western states, flooding along the saltwater coasts and ever-rising temperatures causing drought in different corners of the continent.

The reason for their arrival here is as old as time: Humans reacting to a threatening change in the environment around them and seeking a more habitable place to live.

That’s because climate forecasts are grim. A new report from the National Oceanographic and Atmospheric Administration warns that the U.S. coastline will see up to a foot of sea level rise by 2050 due to climate change.

Many climigrants to the Great Lakes region would most likely come from eastern and southern coastal areas, from the drought-stricken Southwest and West, and from wildfire-vulnerable parts of California and the Pacific Northwest.

Some will leave ahead of disaster with enough resources to resettle comfortably.

Other climigrants may be devastated financially when their homes or businesses are destroyed and they lack flood or other insurance, raising social justice questions for the communities they might move to.

Posted on by admin

June 22, 2022

Reaching “net zero” is easy, cheap, and saves you thousands of dollars, not to mention, you can help save the planet. Here are some things I’ve done to reach net zero without sacrificing my standard-of-living. In fact, I’ve gone beyond net zero in an attempt to eliminate all my pollution. The easiest way to get started is to conserve energy. Don’t use what you don’t need. Turn things off. Unplug things. Buy low energy use products.

1) Electricity and heat are the largest contributors to greenhouse gas emissions.
* choose an electric company that uses nuclear, solar, and/or wind generation
* insulate your house (Be careful not to over insulate. Indoor pollution is as large a health concern as outdoor pollution. An air-tight house needs an air exchange system with a rigorous filter maintenance program.)
* zone heat. In the winter, keep your main temperature at 50 degrees Fahrenheit and only keep the room you are occupying at a comfortable level (68 degrees). Wear warm clothes.
* an air to air heat exchanger and humidity exchanger (Note that humidity is as important as temperature.)
* plant shade trees and eliminate your need for central air
* plant windscreens, such as, evergreens

2) Food and land use is the second largest contributor to greenhouse gas emissions.
* eat less meat
* reduce transportation of food by buying local
* grow your own garden and windowsill gardens
* plant trees, and more importantly, maintain old growth
* reduce impervious surfaces

3) Transportation is the third largest contributor to greenhouse gas emissions.
* buy an EV or high MPG manual transmission (I get 50 MPG in a 4-wheel drive SUV with a 6 speed.)
* make fewer trips, take public transportation, avoid air travel

4) Invest in green technologies. Here are a few suggestions:
RYCEY — Rolls Royce / mini-nuclear plants
HDRO — Defiance Next Gen H2 ETF / green hydrogen
BE — Bloom Energy Corp / fuel cells, green hydrogen
BLDP — Ballard Power Systems Inc / proton exchange membrane fuel cell, green hydrogen
TOSYY — Toshiba Corp / mini-nuclear plants
BP — British energy / green hydrogen, solar, wind
BAESY — BAE Systems / mini-nuclear development
SIEGY — Siemens / wind, green hydrogen

Thank you. My life depends on it.

bookmark_borderCost of Property Insurance in Florida

Posted on by admin

Florida Politics reports in their article, As climate in Florida sets ‘new normal,’ cost of property insurance will separate haves, have-nots:

“Insurers believe that due to climate change, this is the new normal. They’re finding that catastrophic and non-catastrophic weather events are increasing in severity every year,” said Paul Handerhan, president of the Federal Association for Insurance Reform, a national nonprofit advocacy organization based in Fort Lauderdale.

The consequences of climate change not only include catastrophic — and increasingly expensive — weather such as hurricanes and wildfires, but also more everyday events such as storms that pelt residential and commercial properties with straight-line wind and hail.

The actuarially sound way to respond to the new normal is to raise rates, reduce coverage, or throw in the towel, as eight property insurance companies in Florida have done since 2018. Just this week, three others asked state insurance regulators to approve hefty rate increases — as high as 49 percent on policyholders not among the tens of thousands who recently lost coverage altogether due to non-renewals.

Over time, Handerhan said, property insurance coverage will become so expensive that only the wealthiest of the wealthy can “afford to live in paradise.”

“This market is completely,100% out of control,” said Barry Gilway, president, CEO, and executive director of Citizens, during the board of governors meeting. “It all has to do with the total collapse of the overall Florida marketplace, and that collapse continues.”

2021 saw the largest emissions of greenhouse gases in human history.

The Intergovernmental Panel on Climate Change reported:
The Current State of the Climate

* It is unequivocal that human influence has warmed the atmosphere, ocean and land. Widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere have occurred.

* Observed increases in well-mixed greenhouse gas (GHG) concentrations since around 1750 are unequivocally caused by human activities. Since 2011 (measurements reported in AR5), concentrations have continued to increase in the atmosphere, reaching annual averages of 410 parts per million (ppm) for carbon dioxide (CO 2), 1866 parts per billion (ppb) for methane (CH 4), and 332 ppb for nitrous oxide (N 2O) in 2019.6 Land and ocean have taken up a near-constant proportion (globally about 56% per year) of CO2 emissions from human activities over the past six decades, with regional differences (high confidence).

* Each of the last four decades has been successively warmer than any decade that preceded it since 1850.

* Human influence is very likely the main driver of the global retreat of glaciers since the 1990s and the decrease in Arctic sea ice area between 1979–1988 and 2010–2019 (decreases of about 40% in September and about 10% in March).

* It is virtually certain that the global upper ocean (0–700 m) has warmed since the 1970s and extremely likely that human influence is the main driver. It is virtually certain that human-caused CO2 emissions are the main driver of current global acidifcation of the surface open ocean.

Posted on by admin

* Pollution is the largest environmental cause of disease and premature death in the world today
* 1 in 6 deaths worldwide attributed to pollution
* 9 million people per year die from pollution

The Lancet Commission on pollution and health was updated for 2022:

Pollution and health: a progress update 2022 PDF

Key messages
• Over the past two decades, deaths caused by the modern forms of pollution (eg, ambient air pollution and toxic chemical pollution) have increased by 66%, driven by industrialisation, uncontrolled urbanisation, population growth, fossil fuel combustion, and an absence of adequate national or international chemical policy.
• Despite declines in deaths from household air and water pollution, pollution still causes more than 9 million deaths each year globally. This number has not changed since 2015.
• More than 90% of pollution-related deaths occur in low-income and middle-income countries.
• Key areas in which focus is needed include air pollution, lead poisoning, and chemical pollution. Air pollution causes over 6∙5 million deaths each year globally, and this number is increasing. Lead and other chemicals are responsible for 1∙8 million deaths each year globally, which is probably an undercounted figure.
• Most countries have done little to deal with this enormous public health problem. Although high-income countries have controlled their worst forms of pollution and linked pollution control to climate change mitigation, only a few low-income and middle-income countries have been able to make pollution a priority, devoted resources to pollution control, or made progress. Likewise, pollution control receives little attention in either official development assistance or global philanthropy.
• The triad of pollution, climate change, and biodiversity loss are the key global environmental issues of our time. These issues are intricately linked and solutions to each will benefit the others.
• We cannot continue to ignore pollution. We are going backwards.

Posted on by admin

As the climate warms, the air holds more moisture. Theoretically, there is a 7% increase in atmospheric water holding capacity per degree Celsius warming. A recent study published in Nature The conterminous United States are projected to become more prone to flash floods in a high-end emissions scenario suggests extreme precipitation might be increasing even more due to changes in storm structure, storm dynamics, and large-scale weather patterns resulting in even more severe flash flooding that previously projected.

“Flash floods are largely driven by high rainfall rates in convective storms that are projected to increase in frequency and intensity in a warmer climate in the future. US floods are becoming 7.9% flashier by the end of the century assuming a high-emissions scenario. The Southwest (+10.5%) has the greatest increase in flashiness among historical flash flood hot spots, and the central US (+8.6%) is emerging as a new flash flood hot spot. Additionally, future flash flood-prone frontiers are advancing northwards.”

Homeonwers insurance is becoming more expensive or even unavailable due to the increase frequency and intensity of extreme weather events caused by climate change.

NOLA newspapers reports:
Louisiana’s homeowners insurance market straining under weight of 600,000 claims
Two active Atlantic hurricane seasons in a row have made some insurers insolvent.

It’s the latest sign of a deepening crisis taking shape once again in Louisiana, where the legacy of Hurricane Katrina and other storms still looms large. As big national insurers pulled out of coastal areas in the southeast, homeowners increasingly relied on less-regulated regional insurance providers to make them whole in case of catastrophe. Now, even some of those companies — once willing to make a risky bet — are leaving.

In Calcasieu Parish, nearly three out of every four occupied homes filed an insurance claim after Hurricane Laura, according to a Times-Picayune analysis of state and census data. One in four filed claims again less than two months later after Delta made landfall about 10 miles west of where Laura came ashore.

Failures not ‘anomalies’
The flurry of storms was too much for some insurance companies to bear. The Department of Insurance has already seized control of three firms because they could not afford to pay claims.

“I wish I could say I thought they were anomalies, but I don’t,” said Insurance Commissioner Jim Donelon. He said a fourth insurer that’s in dire financial straits will likely be placed under the care of the Louisiana Insurance Guaranty Association.

“I would say our property insurance market is in crisis,” said Jeff Albright, CEO of the Independent Insurance Agents and Brokers of Louisiana. “The sad part of it is we’re reliant on these small, thinly capitalized companies instead of having large national carriers that have lots of assets and can weather the big storms.”

Donelon said five companies have withdrawn entirely from the state and another five or six have stopped writing policies. As a result, Donelon said he expects the number of policies under Louisiana Citizens to double this year as the state launches headlong into another hurricane season.

bookmark_borderUN Climate Report: It’s Now or Never

Posted on by admin

A new flagship UN report on climate change indicating that harmful carbon emissions from 2010-2019 have never been higher in human history, is proof that the world is on a “fast track” to disaster, António Guterres has warned, with scientists arguing that it’s ‘now or never’ to limit global warming to 1.5 degrees.

Reacting to the latest findings of the Intergovernmental Panel on Climate Change (IPCC), the UN Secretary-General insisted that unless governments everywhere reassess their energy policies, the world will be uninhabitable.

His comments reflected the IPCC’s insistence that all countries must reduce their fossil fuel use substantially, extend access to electricity, improve energy efficiency and increase the use of alternative fuels, such as hydrogen.

Unless action is taken soon, some major cities will be under water, Mr. Guterres said in a video message, which also forecast “unprecedented heatwaves, terrifying storms, widespread water shortages and the extinction of a million species of plants and animals”.
Horror story

The UN chief added: “This is not fiction or exaggeration. It is what science tells us will result from our current energy policies. We are on a pathway to global warming of more than double the 1.5-degree (Celsius, or 2.7-degrees Fahreinheit) limit” that was agreed in Paris in 2015.

Providing the scientific proof to back up that damning assessment, the IPCC report – written by hundreds of leading scientists and agreed by 195 countries – noted that greenhouse gas emissions generated by human activity, have increased since 2010 “across all major sectors globally”.

In an op-ed article penned for the Washington Post, Mr. Guterres described the latest IPCC report as “a litany of broken climate promises”, which revealed a “yawning gap between climate pledges, and reality.”

He wrote that high-emitting governments and corporations, were not just turning a blind eye, “they are adding fuel to the flames by continuing to invest in climate-choking industries. Scientists warn that we are already perilously close to tipping points that could lead to cascading and irreversible climate effects.”

bookmark_borderClimate Change Feedback Loops: Brown Carbon, Wildfires, and Arctic Melting

Posted on by admin

Feedback loops accelerate climate change at an exponential rate. In this case, brown carbon from wildfires warms the arctic. The warmer arctic absorbs more heat causing more wildfires. In turn, more wildfires cause more brown carbon resulting in a warmer arctic. The cycle keeps reinforcing itself as it repeats.

A study published in One Earth entitled “Brown carbon from biomass burning imposes strong circum-Arctic warming” reports:
• Brown carbon imposes strong Arctic warming
• Warming effect of water-soluble brown carbon is ∼30% relative to black carbon
• Biomass burning (wildfires) contributes ∼60% of the warming effect of brown carbon
• Warming climate leads to increased wildfires that reinforce Arctic warming

Rapid warming in the Arctic has a huge impact on the global environment. Atmospheric brown carbon (BrC) is one of the least understood and uncertain warming agents due to a scarcity of observations. Here, we performed direct observations of atmospheric BrC and quantified its light-absorbing properties during a 2-month circum-Arctic cruise in summer of 2017. Through observation-constrained modeling, we show that BrC, mainly originated from biomass burning in the mid- to high latitudes of the Northern Hemisphere (∼60%), can be a strong warming agent in the Arctic region, especially in the summer, with an average radiative forcing of ∼90 mW m−2 (∼30% relative to black carbon). As climate change is projected to increase the frequency, intensity, and spread of wildfires, we expect BrC to play an increasing role in Arctic warming in the future.

Posted on by admin

The National Oceanic and Atmospheric Administration reports U.S. coastline to see up to a foot of sea level rise by 2050. That is three times the rate of the previous one hundred years.

“For businesses along the coast, knowing what to expect and how to plan for the future is critical,” said U.S. Secretary of Commerce Gina M. Raimondo. “These updated projections will help businesses, and the communities they support, understand risks and make smart investments in the years ahead.”

“This new data on sea rise is the latest reconfirmation that our climate crisis ⁠— as the President has said ⁠— is blinking ‘code red,’” said Gina McCarthy, National Climate Advisor. “We must redouble our efforts to cut the greenhouse gases that cause climate change while, at the same time, help our coastal communities become more resilient in the face of rising seas.”

“By 2050, moderate flooding ⁠— which is typically disruptive and damaging by today’s weather, sea level and infrastructure standards ⁠— is expected to occur more than 10 times as often as it does today,” said Nicole LeBoeuf, NOAA National Ocean Service Director. “These numbers mean a change from a single event every 2-5 years to multiple events each year, in some places.”

The Sea Level Rise Technical Report provides the most up-to-date sea level rise projections for all U.S. states and territories by decade for the next 100 years and beyond, based on a combination of tide gauge and satellite observations and all the model ensembles from the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). The report projects sea levels along the coastline will rise an additional 10-12 inches by 2050 with specific amounts varying regionally, mainly due to land height changes.
