Wednesday December 4th… Dear Diary. The main purpose of this ongoing post will be to track United States extreme or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials).😉
Bringing On Board Conservatives…Talk About Pollution Instead Of Climate Change
As many of you know I am deeply partisan, being a staunch believer in science, which leads us to know that there is a climate crisis that the entire world most fight. This means the entire world, not just those of us with more liberal minds who are climate activists. One of the big questions as of late 2019 is do we ignore people who disagree with us, leading and dragging them into new policy such as would be produced by the Green New Deal, or can we somehow convince most that big change would benefit their health and bottom line? How can we smooth over any ill will and feelings among people with entirely different psychological makeups?
I certainly would think that the world needs to work in unison to fight the climate crisis, bringing in all people from every political stripe. Recently I saw an older 2017 post put on the Climate Reality Hub instructing my more liberal stripe of folks to talk about pollution produced by the burning of fossil fuels more than just presenting hard climate science in association with a lifetime’s relatively slower temperature and sea level trends in order to convince some conservatives of necessary change. I would certainly agree with this tact, so I am reposting some of these public health arguments for my readers:

Why It’s Vital to Talk About the Climate Crisis’ Impact on Public Health
Openly discussing the threat of climate change to public health will help us prepare for this looming challenge and better protect the American people.
Some issues should rise above the clatter of Capitol Hill discord. Like the air we breathe and the water we drink, they are too fundamental to ignore – and too important to get lost amid partisan squabbling. They are concerns at the heart of the universal human rights we all enjoy.
Public health ranks high among them, and it’s threatened in a critical way by the climate crisis.
Climate change will continue to exacerbate existing threats to health and give rise to new ones. And while the movement for solutions may seem in the throes of an especially challenging moment, addressing the crisis’ impacts on our current and future well-being is not a political issue but an ethical and practical one.
According to the World Health Organization, “Climate change is among the greatest health risks of the twenty first century. Rising temperatures and more extreme weather events cost lives directly, increase transmission and spread of infectious diseases, and undermine the environmental determinants of health, including clean air and water, and sufficient food.”
The impact of the climate crisis on human health is far-reaching, but solutions exist that can help us improve quality of life around the world right now and work toward a healthier, more sustainable future for all.
But to solve a problem, first you’ve got to understand what’s at stake. Here’s a quick look:
The same carbon pollution that causes climate change can indirectly aggravate respiratory concerns like asthma and allergies.
Burning fossil fuels not only pollutes our air directly with irritants like particulate matter and soot, but as greenhouse gases accumulate in the atmosphere and average temperatures rise, they also contribute to higher levels of ground-level ozone that can cause acute and long-term respiratory problems. Moreover, rising global average temperatures lead to longer pollen seasons in many places and – when combined with stronger rainfall events, flooding, and higher humidity – create the perfect environment for mold to flourish.
The result? More allergies, asthma attacks, and other respiratory health problems.
………………………………………………………………………….
As we all know renewables do not admit air pollution, which is choking cities like Beijing China, and elevating levels of ozone at times over cities here in the United States. I have suffered from asthma during my lifetime, which has caused me great pain at times and probably has shortened my lifespan, so anything that can be done to keep air clean, besides keeping greenhouse enhancing gases out of the atmosphere, would be a big plus for us all.
I’m also posting more very detailed information from Dr. Jeff Master’s Category 6 blog on air pollution, which has some recent statistics you may wish to read:
Stopping Human-Caused Air Pollution Would Prevent 5.6 Million Air Pollution Deaths Per Year: New Study

If humans stopped emitting air pollution, an astonishing 5.6 million premature deaths per year due to global outdoor air pollution could be prevented, according to research published Monday. About 65% of these deaths are due to burning of fossil fuels, with the remainder due to such activities as biomass burning and agriculture. Eliminating human-caused air pollution would also significantly reduce drought in monsoon regions, but it would allow more sunlight to reach the surface, increasing Earth’s surface temperature by at least 0.36°C (0.65°F). Overall, the effects would be hugely beneficial.
The study, Effects of fossil fuel and total anthropogenic emission removal on public health and climate, was published in the journal Proceedings of the National Academy of Sciences (PNAS) by a team headed by atmospheric researcher Jos Lelieveld of the Max Planck Institute. The study built on their previous work, published on March 12, which found that the health burden of fine particulate matter (PM2.5) air pollution is much higher than has been previously assumed. They concluded that outdoor air pollution from PM2.5 and ozone causes 8.79 million premature deaths globally each year. Of that total, natural sources of outdoor air pollution accounted for 3.24 million deaths per year, and human-caused sources were 5.55 million per year. According to air pollution scientist Susan Anenberg of The George Washington University, who was not involved in the study, “these results of the new study are in line with previous research showing that the global burden of ambient PM2.5 on mortality could be substantially larger than previously thought, indicating about a doubling of the estimates currently reported by the Global Burden of Disease study.”
The researchers found that the top three nations for human-caused air pollution deaths were China (2.2 million per year), India (1.1 million per year), and the U.S. (230,000 per year). In the U.S., 84% of these deaths were attributed to the burning of fossil fuels. Globally, a premature air pollution death was found to occur on average 26.5 years earlier than it otherwise might have. In the U.S., where the mortality of children from air pollution is lower than the global average, a premature air pollution death takes an average of 12 years off a person’s life, according to Caiazzo et al., 2013.
The new study did not attempt to estimate the costs of air pollution to the economy. But a 2016 report by the World Bank—which used an older estimate of air pollution mortality approximately half as high—found that in 2013, the most recent year full data was available, exposure to outdoor and indoor air pollution cost the world’s economy $5.6 trillion (2019 dollars). These losses were highest in South Asia, East Asia and the Pacific: 7.4 – 7.5% of the regional gross domestic product (GDP). The report estimated that the U.S. suffered $520 billion in health-related damages from air pollution in 2013 (2.9% of the GDP).

Eliminating human-caused air pollution allows at least 0.36°C of “hidden” global warming to occur
The researchers found that by eliminating fossil fuel burning, Earth’s surface temperature would rise by about 0.51°C (0.92°F), due to fewer air pollution particles reflecting sunlight back to space. The largest temperature impacts were found over North America and Northeast Asia–1.5 to 2°C of warming (Figure 1). By further removing all human emissions of air pollution—including biomass burning—a mean global temperature increase of 0.73°C would result, they found. However, if we simultaneously reduced human-caused methane, ozone, and hydrofluorocarbons in the atmosphere—three powerful short-lived greenhouse gases—this 0.73°C increase could be reduced to 0.36°C (1.2°C in the U.S.).
Most importantly, eliminating the burning of fossil fuels would stop the rapid build-up of carbon dioxide in the atmosphere—the main source of increasing global warming. In a press release that accompanied the paper, the authors wrote: “Therefore, cessation of air pollution would lead to a fast rise in global temperatures in the short term, and the Paris Agreement’s 1.5°C target would not be achievable. Nevertheless, it is still possible to limit warming to 2°.”
Less air pollution equals less drought
Another huge benefit of emitting less air pollution would be less drought. In recent decades, India, northern China, Central America, West Africa, and the Sahel region of Africa have experienced a notable drying of the climate. Much of the precipitation that falls in these areas is from the summer monsoon. A monsoon depends upon the contrast in temperature between warmer land areas and cooler ocean areas to drive a large-scale atmospheric circulation that brings moisture-laden air from the ocean to the land. When high levels of PM2.5 air pollution exist over land areas, the monsoon is weakened, since the temperature contrast between land and sea is reduced by the sunlight reflected out to space over land areas.
The model used by Lelieveld and colleagues found that by removing all human-caused emissions of particulate air pollution, rainfall increased by 10 – 70% over densely populated regions in India, 10 – 30% over northern China, and by 10 – 40% over Central America, West Africa, and the drought-prone Sahel region of Africa. Such a significant increase in rainfall would save countless lives by increasing water and food security. Particulate pollution from burning of fossil fuels caused about half of these effects globally, while other human-caused emissions, including biomass burning, contributed the other half.
Less air pollution equals a reduction in extreme “stuck” jet stream patterns
An October 2018 paper by Mann et al. (my review here) found that there has been an increase in “stuck” summertime jet stream patterns of the kind that cause long-lasting and extreme weather conditions over large regions of the globe. Part of this increase in what they called Quasi-Resonant Amplification or “QRA” events has been because human-caused global warming is causing the Arctic to heat up at least twice as rapidly as the rest of the planet. However, if we eliminate emissions of PM2.5 air pollution, the mid-latitudes—where most of the pollution is emitted—will tend to warm up faster than they have been. This will alter the contrast in temperature between the poles and the equator, causing a slower increase in QRA events. QRA events have been responsible for many of the most expensive billion-dollar summertime weather disasters of the past few decades.
Indoor air pollution kills 3.6 million people per year
The study did not take into account that the introduction of clean household energy in low-income countries could substantially reduce excess deaths from indoor air pollution, estimated to be about 3.6 million per year. The phaseout of human-caused emissions is expected to be paralleled by a reduction of household air pollution from the introduction of clean “zero carbon” domestic energy sources. In total, the elimination of human-caused indoor and outdoor air pollution would save 9 million lives per year, the researchers estimated.
Conclusion
The study concluded: “The prospect of preventing millions of excess deaths attributable to air pollution, and restoring perturbations of the hydrologic cycle that have contributed to regional drying, with the cobenefit of limiting climate warming to below 2°C, is compelling and underscores the urgency of acting on global environmental change.”

The case for turning to renewables just on preventing air pollution alone after a couple of centuries of fossil fuel use is very strong for our more conservative friends. I have no doubt that they will also follow us towards a greener future, seeing the light of air pollution arguments for change.
