A time-lapse released Tuesday by the National Oceanic and Atmospheric Administration showed how surface air temperatures have intensified over Mexico and the central and southern United States since May 1.
Studies have shown that climate change is increasing the frequency, severity and duration of extreme heat events. A recent analysis by Climate Central, a New Jersey-based nonprofit research group, found that human-caused global warming made this month’s heat wave in Texas and Mexico at least five times more likely to occur.
Brutally hot conditions are expected to persist Wednesday across Texas, with many places experiencing temperatures well into the triple digits.
Meanwhile, around 87 million people across the Midwest and parts of the Northeast are at risk of poor air quality due to smoke from Canadian wildfires.
The National Weather Service said in an update early Wednesday that the heat dome is expected to “expand northward into the Middle Mississippi Valley” bringing high temperatures that will not cool off much overnight. Forecasters have said that much of the South will likely experience extreme heat and humidity that will persist through the July 4 holiday.
