Heat Warnings Across US As Climate Experts Warn of Spike In Very Hot Days
Source: The Guardian
More than half the US was under excessive heat warnings on Friday amid a brutal heatwave which experts warned could become the new normal because of the climate crisis.
Forecasters warned of very dangerous heat as temperatures rose to 100F (37.7C) particularly in urban areas where the mass of buildings creates heat islands. Alerts were in place in states as far reaching as New Mexico and Maine.
The worst of the heatwave is expected to be felt in Washington DC, Richmond, Virginia and Raleigh, North Carolina, where air temperatures of about 100F are predicted on Saturday and Sunday, with a heat index which is closer to what the temperature actually feels like of 110 to 115F (43.3 to 46.1C).
A heat dome of hot and humid weather is roasting the midwest. The high humidity makes it more difficult for the human body to cool itself down by sweating, because perspiration does not evaporate easily in the moist air.

167 million people are under a heat advisory or excessive heat warning said the National Weather Service.
A NWS meteorologist said, Its very dangerous heat. Its not just how hot its going to get in the day overnight temperatures are only falling into the mid 70s to low 80s. So the big problem, of course, is going to be urban areas because of the heat islands that you get.
June this year was the hottest month in history, a record that could be broken by July. The number of extremely hot days in the US could more than double as the impact of the climate crisis is felt according to a new report from the Union of Concerned Scientists.
Heatwaves are likely to become common as heating across the globe increases their strength and likelihood, and as the impact is felt by millions in the US and by agriculture.

(5,231 posts)I live in SE Michigan. Used to be, 15-20 years ago, August was the tough, hot month. These days it's moved to mid July. And it is like nothing I remember. Suffocating, awful humidity and heat. Relentless. August cools earlier.
Our winters are also more extreme. The polar vortex shifts down from Canada, and from late January through March it's like the Arctic tundra here. We don't see an actual start to spring until late April (used to be late March).
I grow half my food during the summer months. Just something I love to do. I have become a ninja gardener trying to encapsulate all the changes in climate. I no longer grow peas or lettuce (there is no real 'spring' here anymore, so it's not worth it). I worry every single year about my tomato/pepper/tomatillo/potato crops getting enough sunlight and heat before it abruptly cools in mid-August.
I used to have bumper crops all the time. Now I rely on the science I know to eke out what I can (hoophouses, plant placement)...and my yield is far less than it used to be.
I can't even imagine what actual farmers are going through.
