More Junk Climate Science
Timothy Birdnow
Another crazy study to make us all afraid of a modestly warming world.
Heat can age you as much as smoking, a new study finds
Haven't these fools seen Peasants in Russia, or Eskimo women who at age 35 look to be pushing 80?
For that matter the human race came out of the African Rift Valleys where it is freaking hot. We EVOLVED to live in warm climates.
This study looked at people in Phoenix and similar places and said people "looked 14 months older" because of the heat. Uh, did it occur to them to look at other factors, like where the people they were studying came from or their ethnic heritage? If you come from a Third World country you probably will age faster.
There is no question that excessive exposure to sun damages the skin and causes premature epidermal aging. But there are many benefits to sunlight, including vitamin D and other healthful benefits.
FTA:
What were the controls? Did they study people in cold climates, say, Buffalo or Anchorage?
In point of fact they cannot determine the increased temperatures in any meaningful way. The reality is people in warm climates are outside more than those in cooler climates. But they can't say "well, it's gone up five degrees so we see X" because it has NOT gone up five degrees, but rather a fraction of one degree - a statistically insignificant amount - and most of that warming is diurnal, meaning it happens when people are asleep.
I would add almost everyone has air conditioning or evaporative cooling systems and so are in no way subject to increased heat stress. If anything we experience far less heat than our nacestors did. Nobody noticed this before A/C.
Naturally there were no controls for this research. They did not differentiate those who do not have air-conditioning or other environmental factors from those who do not.
The article states:
So he is admitting here he has nothing but a very loose correlation that does not take other environmental factors into account. In short, this is junk science intended to keep the climate change scam alive.
Where did the great civilizations begin? Mesopotamia, Egypt, India, Mexico, all hot places. Only China breaks that pattern. Now why do you suppose civilizations flourished in hot climates? Why didn't they start in Germany or Russia or Canada?
I'm waiting for an answer.

"Biological age is often correlated with chemical tags that accumulate and are shed from people's DNA over time, a process called methylation; it is often referred to as "epigenetic aging." "DNA methylation acts like a light switch for genes — so it can turn them on and off," Choi says.
Methylation doesn't change the genes themselves, but modifies the way those genes work — sometimes for the better, but oftentimes not. Many studies in both animals and humans have shown that DNA methylation patterns change over time and can be used as a sort of molecular clock, ticking along as people age.
Epigenetic aging can accelerate because people don't eat well or don't get enough exercise. But it is also associated with emotional or physical stress, as well as exposure to environmental harms like air pollution "and, in this case, heat," Choi says.
The researchers looked at blood samples from more than 3,600 older adults across the U.S. and assessed people's epigenetic age. They could figure out how much heat those people experienced over a few days, a few months, one year and six years prior to that sample collection using climate and weather models looking into the past, taking into account both temperature and humidity — factors that influence the danger of different heat conditions.
The outcomes were clear. People who experienced more heat over the long-term aged faster, biologically, than those living in cooler places. That's even after taking into account people's financial status, education, physical activity and whether they smoked.
Researchers have known for years that heat exposure correlates with long-term issues like worsened risk of cardiac problems. But "the mechanisms for how that happens haven't been clear," says Tom Clanton, a physiologist and heat expert at the University of Florida's College of Health and Human Performance, who wasn't involved in the research. This work, he says, begins to explain how those delayed effects might happen. At the genome level, heat exposure makes "you sort of accelerate your way towards an old heart, and an old vulnerable heart," he says.

The article states:
"The next step to connect heat exposure to specific health problems, Meade thinks, is to further personalize the analyses, because even within the hottest parts of the country, people experience very different heat exposures. "What people actually experience in their homes, whether they're in an overheated mobile unit or they have air conditioning available, can be wildly different temperatures," he says.
