*Who Is Most At Risk To Extreme Heat? */[ answer:  children ]/
Extreme temperatures associated with heat waves can make everyone 
uncomfortable. When combined with conditions such as high humidity, sun 
exposure, stagnant air, and poor air quality, high temperatures can also 
become a health concern. Some groups face a greater risk of heat-related 
illness than others. For instance, outdoor workers and athletes are at 
greater risk than office workers because they have increased exposure to 
heat. Other groups may be disproportionately affected by the effects of 
high heat as a result of age or poor health, or the lack of resources 
that enable them to adapt or recover. Identifying specific factors that 
increase risk for some populations gives us a way to reduce exposure and 
vulnerability through adaptive actions. In some cases, simply increasing 
awareness of the risks that extreme heat poses to health can encourage 
people to take adaptive actions, such as going indoors or getting to a 
cooling center.

Groups most at risk to heat include, but are not limited to: children, 
older adults, people experiencing homelessness, people with pre-existing 
conditions, indoor and outdoor workers, emergency responders, 
incarcerated people, low income communities, pregnant people, athletes, 
and more.

*Two Heart Medications Tied to Greater Heart Attack Risk During Very Hot 
Weather*
August 01, 2022 - by Jenny Blair
For people with coronary heart disease, beta-blockers can improve 
survival and quality of life, while aspirin and other antiplatelet 
medications can reduce the risk of a heart attack.

But those protections could backfire during hot-weather events, a time 
when heart attacks are more likely. A new study found that, among people 
suffering non-fatal heart attacks associated with hot weather, an 
outsize portion are taking these heart drugs.

“Patients taking these two medications have higher risk,” said Kai Chen, 
an assistant professor in the Department of Epidemiology (Environmental 
Health) at the Yale School of Public Health and first author of the 
study. “During heat waves, they should really take precautions.”...
- -
It turned out that users of beta-blockers or antiplatelet medications 
were likelier to have heart attacks during the hottest days compared to 
control days. Antiplatelet medication use was associated with a 63% 
increase in risk and beta-blockers with a 65% increase. People taking 
both drugs had a 75% higher risk. Non-users of those medications were 
not more likely to have a heart attack on hot days.

The study doesn’t prove that these medications caused the heart attacks, 
nor that they make people more vulnerable to heart attack. Although it’s 
possible that they did increase the risk of heart attacks triggered by 
hot weather, it’s also possible that patients’ underlying heart disease 
explains both the prescriptions and the higher susceptibility to heart 
attack during hot weather.

Still, one clue does suggest the medications could be to blame.

When researchers compared younger patients (25 to 59 years) to older 
ones (60 to 74 years), they found, as expected, that the younger ones 
were a healthier group, with lower rates of coronary heart disease. Yet 
younger patients taking beta-blockers and antiplatelet medications were 
more susceptible to heat-related heart attack than older patients, 
despite the older ones having more heart disease.

Another clue that these two medication types may render people more 
vulnerable: For the most part, other heart medications didn’t show a 
connection to heat-related heart attacks. (An exception was statins. 
When taken by younger people, statins were associated with an over 
threefold risk of a heart attack on hot days.)

“We hypothesize that some of the medications may make it hard to 
regulate body temperature,” Chen said. He plans to try to untangle these 
relationships in future studies.

The results suggest that as climate change progresses, heart attacks 
might become a greater hazard to some people with cardiovascular disease.

/*Triggering of myocardial infarction by heat exposure is modified by 
medication intake*
Nature Cardiovascular Research (2022)Cite this article
Published: 01 August 2022

    *Abstract*
    Acute myocardial infarction (MI) can be triggered by heat exposure,
    but it remains unknown whether patients taking certain
    cardiovascular medications have elevated vulnerability. Based on a
    validated and complete registration of all 2,494 MI cases in
    Augsburg, Germany, during warm seasons (May to September) from 2001
    to 2014, here we show that heat-related non-fatal MI risk was
    elevated among users of anti-platelet medication and beta-receptor
    blockers, respectively, but not among non-users, with significant
    differences between users and non-users. We also found that these
    effect modifications were stronger among younger patients
    (25–59 years), who had a lower prevalence of pre-existing coronary
    heart disease (CHD, a potential confounder by indication), than
    among older patients (60–74 years), who had a higher prevalence of
    pre-existing CHD. Users of these medications may be more vulnerable
    than non-users to non-fatal MI risk due to heat exposure. Further
    research is needed to disentangle effect modification by medication
    use from effect modification by pre-existing CHD.

*Climate Endgame: Exploring catastrophic climate change scenarios*

    *Abstract*
    Prudent risk management requires consideration of bad-to-worst-case
    scenarios. Yet, for climate change, such potential futures are
    poorly understood. Could anthropogenic climate change result in
    worldwide societal collapse or even eventual human extinction? At
    present, this is a dangerously underexplored topic. Yet there are
    ample reasons to suspect that climate change could result in a
    global catastrophe. Analyzing the mechanisms for these extreme
    consequences could help galvanize action, improve resilience, and
    inform policy, including emergency responses. We outline current
    knowledge about the likelihood of extreme climate change, discuss
    why understanding bad-to-worst cases is vital, articulate reasons
    for concern about catastrophic outcomes, define key terms, and put
    forward a research agenda. The proposed agenda covers four main
    questions: 1) What is the potential for climate change to drive mass
    extinction events? 2) What are the mechanisms that could result in
    human mass mortality and morbidity? 3) What are human societies'
    vulnerabilities to climate-triggered risk cascades, such as from
    conflict, political instability, and systemic financial risk? 4) How
    can these multiple strands of evidence—together with other global
    dangers—be usefully synthesized into an “integrated catastrophe
    assessment”? It is time for the scientific community to grapple with
    the challenge of better understanding catastrophic climate change...

*- -
**Conclusions*
There is ample evidence that climate change could become catastrophic. 
We could enter such “endgames” at even modest levels of warming. 
Understanding extreme risks is important for robust decision-making, 
from preparation to consideration of emergency responses. This requires 
exploring not just higher temperature scenarios but also the potential 
for climate change impacts to contribute to systemic risk and other 
cascades. We suggest that it is time to seriously scrutinize the best 
way to expand our research horizons to cover this field. The proposed 
“Climate Endgame” research agenda provides one way to navigate this 
under-studied area. Facing a future of accelerating climate change while 
blind to worst-case scenarios is naive risk management at best and 
fatally foolish at worst.

*The climate bill won’t stop global warming. But it will clean the air.*
Analysis by Chris Mooney
Staff writer
August 1, 2022
The higher temperatures observed today across the world, implicated in 
everything from extreme heat to drought and worsening wildfires, are the 
result of many decades of rising greenhouse gas emissions that trap heat 
and warm the globe. And there are many more emissions to come, as people 
around the globe keep on living, driving cars, conducting business.

All of which explains why the economic and climate deal announced last 
week by Senate Democrats, which would represent America’s biggest 
actions ever to curb climate change, can scarcely be expected to have an 
immediate, measurable impact on the warming planet.

Yet, in ways Americans may not yet appreciate, the legislation could 
have much more direct, soon-felt effects — on what people pay to drive 
and power their homes, as well as the quality of the air they breathe.

The deal, announced by Sen. Joe Manchin III (D-W.Va.) and Senate 
Majority Leader Charles E. Schumer (D-N.Y.), would spend $369 billion on 
tax credits and other spending to transition the country away from 
fossil fuels.

By doing so, the Inflation Reduction Act would further lower the costs 
of renewable energy technologies such as wind and solar, as well as many 
other less glitzy but important energy-saving appliances and devices 
around the home. If it spurs other countries to act in concert with the 
United States, it would be at the cutting edge of a global coordinated 
effort to cut down on emissions and limit warming.

The legislation “is important symbolically and internationally,” said 
Rob Jackson, an expert on global greenhouse gas emissions at Stanford 
University. “Its biggest benefits are to provide longer-term certainty 
for renewables development and to promote sales of lower-cost electric 
vehicles. It’s critical the U.S. do something."

Yet, the bill won’t lead to a much cooler planet, at least not 
immediately or on its own. The climate problem is massive, which means 
that even when the United States takes decisive action it can appear 
relatively small...
- -
*Making the world take notice*
U.S. emissions quickly mingle in the atmosphere with emissions from all 
over the globe and trap infrared heat, preventing it from escaping into 
space, traveling wherever the winds take them.

That’s why when the planet warms and the odds of extreme weather events 
shift, it is difficult to blame that on any one country. And when one 
country reduces emissions, it is hard to discern the climatic effect 
amid all the other pollution from all the other countries.

And yet, the legislation will likely have at least some cooling effect 
on its own, and could have a far bigger one if it serves as an economic 
or political catalyst that gets other countries to also up their climate 
ambitions.

Until now, with its pledge of reducing emissions by at least 50 percent 
by 2030, the Biden administration has promised more climate progress 
than existing policies are actually capable of achieving. The result is 
an “implementation gap,” as Joeri Rogelj, an expert on emissions 
policies and trajectories at Imperial College London, puts it.

But the new legislation helps to change that. While experts generally 
say it would not go all the way toward reaching the Biden goal for 2030, 
it brings the country a lot closer than before.

But even if the United States does make its goal, the world will remain 
off course.

“Closing this gap is of course good, but it doesn’t address the 
‘ambition gap,’ ” said Rogelj. “The latter is the gap between 
[countries’ promises] and the emissions reductions that should be 
achieved to put the world” on a path toward limiting warming to 1.5 
degrees Celsius above preindustrial times.

It’s possible, however, that the new U.S. actions could inspire other 
countries to act too. Many have been skeptical about lowering their 
emissions when the country that has emitted more greenhouse gases than 
any other, over the course of history, seemed not to be keeping its word.

The new legislation “gives the U.S. a bit more credibility with the rest 
of the world that we are serious about cutting our emissions,” said John 
Sterman, a climate policy expert at the Massachusetts Institute of 
Technology. “We cannot expect to influence China, India, and other large 
emitters to take serious action on climate change if we are not willing 
to do so ourselves.”

For Stokes, there’s another global benefit. If clean energy technologies 
become cheaper due to investments made in the United States, that means 
they become cheaper everywhere. Which means that emissions reductions 
from the legislation could impact the progress of many other countries 
as well.

“It reduces the technology cost, which spills over across borders,” 
Stokes said.

August 2, 2006: Republican televangelist Pat Robertson calls for action 
on human-caused climate change, a position he would abandon several 
years later.

    (RNS) The overwhelming heat that blanketed much of the East Coast in
    early August has convinced religious broadcaster Pat Robertson that
    global warming is a reality.

    “It is the most convincing evidence of global warming I’ve run into
    in a long time,” Robertson said Thursday (Aug. 3) during his “The
    700 Club” television show. He previously had been critical of claims
    about the dangers of climate change.

    Robertson’s reaction to the hot weather is the latest pronouncement
    in a year that has featured different sets of evangelical leaders
    issuing statements and counter-statements about whether or not
    global warming is a serious, human-caused threat.

    “I have not been one who believed in this global warming, but I tell
    you, they’re making a convert out of me with these blistering
    summers,” Robertson said on his show the day before his Thursday
    statement.

    “And it is getting hotter, and the ice caps are melting, and there
    is a buildup of carbon dioxide in the air. And I think we really
    need to address the burning of fossil fuels. If we are contributing
    to the destruction of this planet, we need to do something about it.”

    The Rev. Jim Ball, spokesman for the Evangelical Climate Initiative,
    welcomed Robertson’s change of heart and said his comments
    demonstrate “the kind of leadership we need to move beyond the vague
    concern of some religious figures.”

    In February, Ball’s group issued a “call to action” signed by more
    than 80 leaders that urged evangelicals to address climate change.
    It plans to hold a series of educational forums on college campuses.

    In late July, the Interfaith Stewardship Alliance issued a rebuttal
    to the initiative’s statement that questioned its assumptions that
    global warming will be catastrophic and that human emissions of
    carbon dioxide are one of its primary causes. It was signed by more
    than 100 evangelical theologians and scientists.
