CDC says in its guidebook:
Extreme heat is a real danger to human health that will become worse with time. Experts project that as our climate changes, extreme heat events in the United States will become more frequent, longer lasting, and more severe.2,3 By the end of this century, extremely high temperatures that currently occur once every 20 years could happen as often as every two to four years.
The weather people are advising that today’s high temperature in Phoenix, Arizona will be 111F. It’s like this every summer; sometimes more, sometimes less. And life is as normal, with kids in swimming pools and cooking outdoors. But drinking plenty of water in important. So the summer is similar to this all across the southwest deserts of the U.S. And we get used to it. If there were any “climate change” going on, people would just accomodate thenselves. And it’s much better than freezing weather.
Extreme heat events are a reality. There’s no evidence of them trending in recent decades, though.
Where’s the one for extreme cold?
