Dangerous heat predicted to hit 3 times more often in future

BY SETH BORENSTEIN

What’s considered officially “dangerous heat” in coming decades will likely hit much of the world at least three times more often as climate change worsens, according to a new study.

In much of Earth’s wealthy mid-latitudes, spiking temperatures and humidity that feel like 103 degrees (39.4 degrees Celsius) or higher -- now an occasional summer shock — statistically should happen 20 to 50 times a year by mid-century, said a study Monday in the journal Communications Earth & Environment.

By 2100, that brutal heat index may linger for most of the summer for places like the U.S. Southeast, the study’s author said.

And it’s far worse for the sticky tropics. The study said a heat index considered “extremely dangerous” where the feels-like heat index exceeds 124 degrees (51 degrees Celsius) — now something that rarely happens — will likely strike a tropical belt that includes India one to four weeks a year by century’s end.

“So that’s kind of the scary thing about this,” said study author Lucas Zeppetello, a Harvard climate scientist. “That’s something where potentially billions of people are going to be exposed to extremely dangerous levels of heat very regularly. So something that’s gone from virtually never happening before will go to something that is happening every year.”


Zeppetello and colleagues used more than 1,000 computer simulations to look at the probabilities of two different levels of high heat -- heat indexes of 103 degrees (39.4 Celsius) and above 124 degrees (51 Celsius), which are dangerous and extremely dangerous thresholds according to the U.S. National Weather Service. They calculated for the years 2050 and 2100 and compared that to how often that heat happened each year across the world from 1979 to 1998.

The study found a three- to ten-fold increase in 103-degree heat in the mid-latitudes even in the unlikely best-case scenario of global warming limited to only 3.6 degrees (2 degrees Celsius) since pre-industrial times -- the less stringent of two international goals.

There’s only a 5% chance for warming to be that low and that infrequent, the study found. What’s more likely, according to the study, is that the 103-degree heat will steam the tropics “during most days of each typical year” by 2100.


Chicago hit that 103 degree heat index level only four times from 1979 to 1998. But the study’s most likely scenario shows Chicago hitting that hot-and-sticky threshold 11 times a year by the end of the century.

Heat waves are one of the new four horsemen of apocalyptic climate change, along with sea level rise, water scarcity and changes in the overall ecosystem, said Zeppetello, who did much of the research at University of Washington state during the warming-charged 2021 heat wave that shattered records and killed thousands.

“Sadly, the horrific predictions shown in this study are credible,” climate scientist Jennifer Francis of the Woodwell Climate Research Center, who was not part of the study team, said in an email. “The past two summers have provided a window into our steamy future, with lethal heat waves in Europe, China, northwestern North America, India, the south-central U.S., the U.K., central Siberia, and even New England. Already hot places will become uninhabitable as heat indices exceed dangerous thresholds, affecting humans and ecosystems alike. Areas where extreme heat is now rare will also suffer increasingly, as infrastructure and living things are ill-adapted to the crushing heat.”


The study focuses on the heat index and that’s smart because it’s not just heat but the combination with humidity that hurts health, said Harvard School of Public Health professor Dr. Renee Salas, who is an emergency room physician.

“As the heat index rises, it becomes harder and harder to cool our bodies,” Salas, who wasn’t part of the research team, said in an email. “Heat stroke is a potentially deadly form of heat illness that occurs when body temperatures rise to dangerous levels.”

I wish that I had posted this earlier in the summer. I suggest that temperatures in th ehigh seventies with very high humidity could themselves be troublesome. 

Dogs are more vulnerable than people to extreme heat.  Using the same chart:

........

• When the heat index reaches caution dogs should not be outside for more than 20 minutes with shade and water. 
• When the heat index reaches extreme caution dogs should not be outside for more than 10 minutes. 
• When the heat index reaches danger or extreme danger no dogs should be outside.

I checked the old posts, and I had a better chart for heat indexes relating heat and humidity to danger. Here we go again:

 [Image: heat-index-chart-relative-humidity.png]

I prefer this one for showing the effects of high temperatures and low relative humidity. 

130F (roughly 55F) is a heat index, of extreme danger, and with 100% humidity it is possible at 90F. With as little as 14% relative humidity such is possible at 126 F. So you can't say "It's the humidity and not the heat". It's both.  One must take shelter from this sort of heat. A hint: many heating decices warn people to not heat water above 120F due to the risk of thermal injury. 

Between 105F and 129F is "very hot". This is itself dangerous. 104F with 35% relative humidity will put you at the lower borderline. So will 14% with 108F... and 86F with 100% humidity, which one would find within the hottest parts of the western Pacific Ocean. Swimming in water that warm will not cool you. I experienced this a few times last week with temperatures just under 90F but high humidity (this is southern Michigan)
. After rains abated one late afternoon I was able to believe that because the sky was overcast conditions might be humiud but not hot. It was both. I lasted about 15 minutes mowing the lawn and had to quit. 

When not exerting myself -- and sleep is clearly non-exertion -- I awoke with leg cramps several times in the last two weeks. Ouch!  
90F to 104F   is simply "hot". 

"Very warm" is possibly too much for your dog even if you can acclimatize yourself to it.

Interesting graphic here. This suggests the sort of transformation of climate in two states with highly-distinctive states that I know well (Michigan and Illinois). Only the lower peninsula is shown for Michigan. Basically their shapes end up with climates characteristic of other places. No, the states are not moving, but climate patterns are moving from elsewhere into Illinois and Michigan:


[Image: 22-44deab86cb.png]
Summers apparently warm even more. Winters in Chicago become more like those of Springfield, Missouri, with winter near St. Louis (Missouri) becoming more like winter in Dallas. Detroit becomes more like Roanoke, Virginia with Lansing winters becoming more like those of Charleston, West Virginia. The Mackinac Bridge gets a climate zone more like that of Cleveland. Although moving only one state does not seem that remarkable, that is a huge north-south switch -- about 325 miles That's a huge climatic difference in Michigan

Summers are even more marked. Illinois mostly covers hot, humid East Texas with Chicago near Texarkana, Cairo near Galveston, and Moline about where Dallas is. Michigan effectively moves into an area that stretches from Popular Bluff, Missouri at the Strait of Mackinac with Detroit near Columbus -- Mississippi, and not Ohio. Today, Chicago and Detroit are about as far south as one can get without air conditioning without a serious compromise to personal health. Even the northernmost part of Michigan ends up with summers in which having no air conditioning is one way to shorten one's lifespan.

With respect to climatic boundaries, the Cfa-Dfa climate boundary (between places having a freezing month on average and having none) that follows roughly the path of I-70 from St. Louis to Columbus, Ohio shifts into Wisconsin and approaches Alpena and Cadillac in Michigan. The zone of sweltering summers passes completely through both Illinois and the Lower Peninsula of Michigan. 

Summers may tend to be slightly drier due to lesser rainfall, but more severely and more certainly higher temperatures that cause more evaporation. This could bring Mediterranean conditions to the Lake Michigan shoreline of Michigan, which would be unwelcome because Michigan lacks the good catchment basins necessary for storing water for irrigation.

The San Joaquin Valley is in deep trouble, as is much of Utah. Parts of Nebraska, Kansas, and Oklahoma are in deep trouble from drought.

As I write this, Florida is getting raked with a horrible hurricane whose first letter is "I". It's not even October yet and we are up to our ninth named tropical storm or hurricane. Hurricanes for over very warm ocean waters, and global warming makes tropical seas even hotter with the air above them more juiced from evaporation of warm sea water.

Hurricanes happen with or without global warming, but nine in the month of September is unusually high. As one of the most effective ways of the earth's atmosphere to disperse excessive heat in the tropics, most of whose surface is water, some of it among the most consistently-warm-to-hot places on Earth, hurricanes seem likely to be more frequent and severe in the wake of AGW.

Although it is impossible to ascribe natural disasters from plagues (like COVID-19) earthquakes to cyclonic storms, forest fires, droughts, floods, heat waves, and cold waves to political leaders, responses to them reflect the character and competence of political leaders. This applies from Theodore Roosevelt (1906 San Francisco Earthquake) to Donald Trump... and now Joe Biden. Bungled responses to such natural disasters can topple regimes unable and unwilling to deal with them, such as the Somoza regime of Nicaragua.

An incompetent, offensive response to a natural disaster (as by Donald Trump) might have political effects. Good leaders can prepare at the least for hurricanes by arranging evacuations and relief 'in the event of', as Obama did for hurricanes in Florida while President. Theodore Roosevelt could do nothing but give the only American institution (the Armed Forces) a free hand in the aftermath of the 1906 San Francisco Earthquake, for which San Francisco has monuments to General Funston). Military-style regimentation has its merits in the wake of disasters.

Response to Hurricane Ian may be the acid test of the Biden administration. Aside from stewardship of economics and foreign policy and in rare cases major wars, little can better demonstrate the competence and moral values of a President of the United States (or analogous leaders elsewhere). Natural disasters are the wrong time for partisan bickering; human lives are at stake.

A single hurricane is hardly proof of AGW, but so many this early is consistent. Hurricane Ian is already a big killer and a cause of economic damage far from complete, let alone from the last calculation. It has raked Cuba,  Florida, and South Carolina so far.  

I saw a video of a man waving the vile flag reading "F--- BIDEN" as the hurricane approached in Florida. I hope that the fool survived, but I can't be so generous about his banner. I am not sharing that video because it offends my sensibilities on two different counts.


Quote:CHARLESTON, S.C. (AP) — Rescuers searched for survivors among the ruins of Florida’s flooded homes from Hurricane Ian while authorities in South Carolina waited for daylight to assess damage from the storm’s second strike as the remnants of one of the strongest and costliest disasters to ever hit the U.S. continued to push north.


The powerful storm terrorized millions of people for most of the week, battering western Cuba before raking across Florida from the warm waters of the Gulf of Mexico to the Atlantic Ocean, where it mustered enough strength for a final assault on South Carolina. It has since weakened to a still-dangerous post-tropical cyclone and was crossing North Carolina toward Virginia overnight, pushing heavy rains toward the Mid-Atlantic states.

At least 30 people were confirmed dead, including 27 people in Florida mostly from drowning but others from the storm’s tragic aftereffects. An elderly couple died after their oxygen machines shut off when they lost power, authorities said. Meanwhile, distraught residents waded through knee-high water on Friday, salvaging what possessions they could from their flooded homes and loading them onto rafts and canoes.

One group of people who will be particularly vulnerable to hurricanes, heat waves, and forest fires, all of which are likely to become more common and more severe with global warming. Less mobile and often out of funds for making the necessary escapes they are the people most at risk from meteorological disasters.

Comment by me: if she were a bit shorter she might have drowned. If she had needed oxygen she might have suffocated due to a loss of electric power to keep her oxygen tank powered.

Almost all of the dozens of people killed by Ian in hardest hit Lee County were 50 or older, with many in their 70s, 80s and even 90s. That’s highlighted the rising dangers for those least likely to be able to flee such disasters and those most likely to be impacted by the aftermath.

FORT MYERS, Fla. (AP) — Older people with limited mobility and those with chronic health conditions requiring the use of electrically powered medical devices were especially vulnerable when Hurricane Ian slammed into Southwest Florida, and experts warn such risks to society’s oldest are growing as disasters increase with the impact of climate change.
Almost all of the dozens of people killed by Ian in hardest hit Lee County were 50 or older, with many in their 70s, 80s and even 90s. That’s highlighted the rising dangers for those least likely to be able to flee such disasters and those most likely to be impacted by the aftermath.
Climate change makes hurricanes wetter and more powerful, but it also increases the frequency of heat waves like ones that scorched the Pacific Northwest the last two summers, killing scores of mostly aged people. It’s also intensified drought fueled wildfires like the inferno that incinerated the California town of Paradise in 2018, killing 85 people, again mostly older.

“It’s not terribly surprising that physically frail, socially isolated people are the most likely to die in these events. But it is politically significant,” said New York University sociology professor Eric Klinenberg. “If we know people are at risk, why aren’t we doing more to help them?”


Klinenberg, who wrote the book “Heat Wave: A Social Autopsy of Disaster in Chicago” about extreme heat that killed more than 700 mostly older and Black people in July 1991, called Ian a mere preview.

“We saw this happen in Chicago, in (Hurricane) Katrina, in (Superstorm) Sandy, and we are going to see more and more as the globe becomes increasingly hotter,” he said.



Florida in particular will feel the increased impact of climate-fueled disasters, sitting in the path of many Atlantic storms and with a large share of retirees drawn by warm weather, a vast coastline and relatively cheap housing. About 29% of Lee County’s population is 65 and older.


One of the more dramatic stories of Ian demonstrates the risks. Johnny Lauder’s 86-year-old mother Karen Lauder, who uses a wheelchair, initially refused to evacuate. But as the water inside her home began to rise nearly above her head, she was unable to flee and her son had to come rescue her [url=https://apnews.com/article/hurricanes-floods-florida-storms-hurricane-ian-244a53254e8eaa5e948eace94db4b141]in an ordeal he documented.

The extreme dangers some face when they lose power was especially clear in Lee County, where an 89-year-old man died after the electricity he needed for his oxygen went out and then his backup generator failed.


Florida has attempted to address some of these issues by setting up shelters where people with health conditions that require electricity for oxygen, dialysis and devices like ventilators can preregister to stay.



AARP Florida Director Jeff Johnson praised the special shelters, saying the state’s county emergency management agencies had modernized and improved evacuation operations the past two decades.



“There is room for improvement, but it would be wrong to say they aren’t doing anything,” he said.
Home-based networks that deliver care and services to older people, as well as neighborhood associations and faith communities can also help by checking on socially isolated older people, Johnson said.

I'm cheering for some blizzards here in Michigan. Agriculture is the #2 business here in Michigan, and farmers need blizzards to supply and protect groundwater. If I married some rich widow who has a second home in Florida I would be leery of going to Florida in September and October. My pretext would be to see the beautiful fall foliage in Michigan.

Blizzards aren't fun, but if you wimp out because of them there is a spelling for relief. F-L-O-R-I-D-A. I can't run as fast as I used to, and I certainly don't want to get caught in my car in floodwaters. December to early April... Florida is OK.

The Midwest is one of the only places in the world which is actually doing better because of global warming. The average temperature has risen, but, rather than seeing different ranges throughout the day, this has largely manifested as milder nighttime temperatures on account of higher humidity. This will likely be a boon to farmers and agricultural exports, as supply chains have made access to fertilizer difficult, and the soils of the midwest require relatively little compared to most other regions (nationally, and, especially, internationally).

Referring to the eastern Midwest, where the water supply is adequate (unless summer rains disappear; Mediterranean climates are great for agriculture if people can store water in deep, narrow reservoirs in mountainous terrain) the effect will be a longer growing season. There might be two crops in a year, which would support a larger population. The difference between a Cfa (mild-winters with all-year rain)   and a Dfa or Dfb (real winters but all-year precipitation, including snow) climate is typically about 59 people per square kilometer and 118 people per square kilometer. Higher productivity of food makes life less costly than otherwise. Food is a big part of the cost of living, and if not food, then heating fuel and winter clothing. 

https://www.youtube.com/watch?v=sXpH4dEIkZA

The question in the western Midwest is where the climatic boundary between steppes and humid climates lies. On the dry side, wheat farming gives way to rangeland. Wheat is the grain crop most tolerant of dry weather. Everything else in the middle latitudes requires more water.

New Study Indicates That We Are at a Catastrophic Ocean Warming “Tipping Point”

By UNIVERSITY OF BIRMINGHAM NOVEMBER 8, 2022

[Image: notWebP]
Global Warming Melting Ice

It is estimated that melting ice in the Antarctic could sea levels to rise by up to 50 meters. A new study charts 45,000,000 years of Antarctic temperature change.

Scientists have created the first charts of Antarctic ocean temperatures over the last 45 million years using molecular fossils and machine learning, providing vital insights into future sea level changes.

The researchers, led by experts from Victoria University of Wellington (NZ) and Birmingham (UK), believe their results indicate that we are near a “tipping point” where ocean warming driven by atmospheric CO2 could trigger catastrophic rises in sea levels due to melting ice sheets. Their findings were recently published in the journal Nature Geoscience.

In the study, the scientists examined molecular fossils from core samples taken during ocean drilling projects. The fossil remains are single lipid (water-insoluble) molecules created by archaea, which are single-celled organisms similar to bacteria. The archaea adjust the composition of their outer membrane lipids in response to changing sea temperatures. Scientists can infer the ancient sea temperature that would have surrounded a certain sample as it died by analyzing these changes.

While these molecular fossil techniques are well used by palaeoclimatologists, the team from Wellington (NZ) and Birmingham (UK) went a step further. They used machine learning to refine the technique, giving the first record to date of changing Antarctic sea temperatures throughout much of the Cenozoic period – covering the past 45 million years.

That means scientists are able to pinpoint much more accurately the historic temperatures which caused ice sheets to grow and shrink during that period. The future loss of ice sheets and the retreat of glaciers in the Antarctic is critically important as melting ice in the region could sea levels to rise by up to 50 m.

“The record we’ve produced offers a much more robust overview of fluctuating Antarctic temperatures and how these relate to changes in the amount of ice, and the topography of Antarctica, over this period and paves the way for improved estimates of future events,” explains the Birmingham lead author Dr. James Bendle.

The link between CO2, sea-surface temperatures, and the amount of ice in Antarctica is clear through the last 45 million years. But one surprising finding was that ocean cooling did not always correspond to increases in Antarctic ice. Specifically for a 1 million-year-long period of ocean cooling from 25 to 24 million years ago. “We show that this is likely related to tectonic subsidence and the influx of relatively warm ocean water in the Ross Sea region,” says Dr. Bendle.

“We can see that ice in Antarctica is currently changing – not least with the loss of some ice shelves and cracks appearing recently in the Thwaites Glacier, one of the largest glaciers in the region. This new study of Earth’s past is one of the clearest indications yet that humans continue to produce CO2 levels for which we can expect major ice loss at the Antarctic margins and global sea-level rise over the coming decades and centuries.”

The team plans to continue to apply biomarker and machine learning approaches to reconstruct the climatic evolution of Antarctica and implications for future warming and sea-level rise.

Florida? A place that votes 17-20% margins for looney culture warriors and covid and election deniers is not the place to go or live for anyone but fools. And they are voting for the hurricanes that hit them over and over again, and they never learn. And older white people like the lady in the picture you posted above are the most likely to vote for what she experienced. Did she learn, and vote Democratic? Probably not. The new Hurricane Nicole is one of only two in recorded history that have happened this late in the season. Will Floridians learn? Not on your life. They'd rather drown than vote for the Party that can reduce these disasters by boosting renewable energy and electric cars (or even more nuclear power; something needs to be done to reduce greenhouse has emissions!). They'd rather vote to prohibit people from saying "gay" or reading about their history. Shame on Florida. God damn Florida. May it sink into the sea.

I don't know why you and other conservatives choose to forget the horrific storms that have wiped out whole sections of midwest states such as Iowa and Nebraska. And it just voted for more.

I'm not forgetting anything. On balance, it's still been a positive. Your question is easy to answer though: we're voting against toxic woke policies, more lockdowns, rent controls and other policies that have turned the coasts into disaster zones.

In all honestly, I would love to see a freshly right wing environmentalist movement. "You've had decades to try to do something about this and all your policies sucked. It's our turn now...".

You are forgetting a lot because you put your prejudices (calling those who don't hold them "woke") ahead of policies that actually help the people avoid disasters. Or you believe neoliberal trickle-down economics that says the government should not restrain greedy owners with rent controls, or believe conspiracy theories or slogans that deny that health measures needed to be imposed collectively and not just individually in order to stop the spread of an extremely dangerous, contagious disease. No right winger could possibly enable an environmentalist movement. Neoliberalism precludes any collective action and puts all responsibility on each one of 7 billion individuals to make a decision to go against what is convenient to buy.

And you call the coasts, and not your own southern swamplands, "disaster zones", even though those Dixie swamp lands are the least developed and most prejudiced, poor, backward, deceived region in the entire developed world, and more backward even than many regions of the less-developed world. And people there vote for this. It costs more money to live in the coastal blue states because it is the most desirable and lucrative place to be in the USA, so housing prices rise and homelessness has to be dealt with. These areas are desirable largely because we vote correctly, and your area does not.
