Deadly Humid Heat in the USA

Posted on 2023/10/102023/10/10 by admin

Deadly humid heat affects billions including the US Midwest this century. “It’s very disturbing,” study co-author Matthew Huber of Purdue University. “It’s going to send a lot of people to emergency medical care.”

The study Greatly enhanced risk to humans as a consequence of empirically determined lower moist heat stress tolerance was conducted by Purdue and George Mason University and published August 15, 2023.

These results indicate that a significant portion of the world’s population will experience — for the first time in human history — prolonged exposures to uncompensable extreme moist heat. Humans will struggle to adapt to these conditions in a warmer world as they will present widespread challenges across many aspects of food–energy–water security, human health, and economic development including in the world’s most populous and most vulnerable regions.

Energy, Heat and Global Warming

I ask:
Is there anything humans do with energy that results in less heat?

For example, furnaces generate heat, refrigerators generate heat, light bulbs generate heat, computers, cars, fans and even air conditioners create more heat.

Is there anything that we do that has a net loss of thermal energy or does the use of energy (period. both fossil fuel and renewable energy) by humans add to global warming?

Sidd replies:
Not just humans. Anytime energy is converted from one form to another and work is extracted by any agency, not just humans, some is lost as heat energy. That’s the second law of thermodynamics.

But to put it in perspective, lets say you burn a pound of coal, and take all the chemical energy out as heat. The amount of heat you directly obtain is several hundred times smaller than the heat trapped by the carbon dioxide generated over the next many thousand years that it remains in the atmosphere… so, don’t burn coal, oil or any fossil carbon.

Thus, for example conversion of AC to DC electricity can be very close to 100% efficient… but if you take out some of the energy and do work with it, you will lose some energy as heat.

The second law of thermodynamics states that the total entropy of an isolated system always increases over time, or remains constant in ideal cases where the system is in a steady state or undergoing a reversible process. The increase in entropy accounts for the irreversibility of natural processes, and the asymmetry between future and past.

The second law has been expressed in many ways. Its first formulation is credited to the French scientist Sadi Carnot in 1824, who showed that there is an upper limit to the efficiency of conversion of heat to work in a heat engine.

Temperature Reaches 123 Degrees in India

Posted on 2016/05/21 by admin

The temperature went over 123 degrees (50C) in India. This was the highest temperature ever recorded in the country.

“Fishermen are advised not to venture into the sea along and off Tamil Nadu and Puducherry during the next 24 hours, along and off Andhra Pradesh coast during the next 48 hours and also and off the Odisha coast on 19th and 20th of May,” the IMD (India Meteorological Department) said in an advisory on Wednesday. –

Deutsche Welle reported, “The heat wave comes as India suffers its worst drought in decades, affecting around 330 million people. Drinking water is running short in many areas and poor rains have prompted the central government to send water trains to regions affected by drought. Hundreds of people have died and crops have been destroyed in several states.”

Heading Toward Hottest Year On Record

Posted on 2014/10/20 by admin

The The National Oceanic and Atmospheric Administration (NOAA) released a report showing “Global temperature reaches record high in September”.

Global Highlights

The combined average temperature over global land and ocean surfaces for September 2014 was the highest on record for September, at 0.72°C (1.30°F) above the 20^th century average of 15.0°C (59.0°F).
The global land surface temperature was 0.89°C (1.60°F) above the 20^th century average of 12.0°C (53.6°F), the sixth highest for September on record. For the ocean, the September global sea surface temperature was 0.66°C (1.19°F) above the 20^th century average of 16.2°C (61.1°F), the highest on record for September and also the highest on record for any month.
The combined global land and ocean average surface temperature for the January–September period (year-to-date) was 0.68°C (1.22°F) above the 20^th century average of 14.1°C (57.5°F), tying with 1998 as the warmest such period on record.

U.N.: Humans Induce Climate Change

Posted on 2013/09/23 by admin

UN Secretary-General Ban Ki-moon warned that “we cannot accept a rising tide that floats only some boats and leaves many to drown.”

Ban Ki-moon has been taking a strong stance on global warming. His latest efforts include getting world leaders to admit humans are impacting climate change. Most people would think this is a given. No. In fact, quite a few government and business leaders refuse to admit to what science shows.

“Nobody can benefit from catastrophic climate change or rampant unemployment and the social unrest that comes with it,” Mr. Ban said.

UK newspaper The Independent says. “The UN’s Intergovernmental Panel on Climate Change (IPCC) will say next week that certainty has increased from “very likely” to “extremely likely” that human activity has caused more than half of the observed temperature rise from 1951 to 2010, in a large part due to fossil fuels and deforestation.”
