Intense heat covers a huge part of the country, with the exception of those in Great Lakes and New England (lucky bastards) A staggering 81 million people live in areas covered by some form of heat warning from the National Weather Service.
Last heat in some ways, this is the worst blow ever to hit the United States. Regional heat was name of the game this summer, but the current heatwave is shocking in both its scale and magnitude. Three-digit temperature values affecting places as diverse as Washington and Louisiana.
The bad news for hot spots is that high temperatures are expected to persist through the weekend in many places. Worse, heatwaves are expected to intensify next week in parts of the Pacific Northwest and Northern Rockies. Yes, this is the story of the summer. But also the history of the era of climate change, when intense heat is the norm and is nowhere immune from its consequences.
Our Grozny Friend, hot dome
This summer we had ample opportunity to talk about thermal domes. It sucks because they suck. Or at least they suck if you prefer your weather not to be like a sauna or steam room.
Much of the US is under high pressure right now. This captures the mostly sunny sky, which intensifies the heat on the ground, which in turn holds even higher pressure. It’s a vicious circle that plays out all too often this year. The most striking example is the fried in the Pacific Northwest in late June – early July. But other thermal domes formed, which led to mind-blowing temperatures, including in Death Valley. referencing the highest reliably recorded temperature anywhere on earth. (He set a record same place last year because this is the world we live in.)
More, This a week The iteration stands out for how widespread the heat is. Seriously, take a look at this map with weather warnings from the National Weather Service. Red, purple and orange are damn hot. And as you can see, things are going damn hot right now in many places in the United States.
Some other colors are also not very good and may be associated with high temperatures. Gray, for example, means poor air quality. These warnings occur downwind of heat-fueled wildfires. Fire brigades in the Northwest struggle in Bootleg Fire, the largest fire in the United States, said they “need to be prepared for anything” because of the rising heat. Those on the leeward side of the fire seem to be too.
Heat tastes differently (but they are all bad)
While it might be one dome to control them all, the heat across the country feels differently depending on where you are. In the Pacific Northwest, this is mostly dry heat. Although there will be dry heat in parts of Washington and Oregon on Saturday, with temperatures as high as 108 degrees Fahrenheit (42.2 degrees Celsius).
“The midday heat, combined with unusually warm night temperatures on Friday nights and Saturday nights, will make it difficult for residents without air conditioning to control heat build-up in their homes,” forecasters wrote to the NWS in their excessive heat warning for the region. broke out during the heatwave that hit the region in late June and ended hundreds of dead as a result.
Air conditioners are much more common in the South than in the Pacific Northwest., but the heat in the south too comes with an explosion of moisture that still makes it incredibly uncomfortable and yet dangerous. With this humidity in mind, the heat index is expected to exceed 113 degrees Fahrenheit (45 degrees Celsius). Wet bulb temperature is an indicator that includes heat, humidity and some other factors, key climate indicator– hovered around 90 degrees Fahrenheit (32.2 degrees Celsius) and even reach the area from Dallas to Florida. These readings high enough that they can lead to serious heat-related illness in healthy people, and even death for those who spend an hour outside in the sun.
Climate change, Climate change, Climate change
Repeat one more time with me guys: climit change. This makes extreme heat more likely and more intense. We cannot talk about a burning hellish summer, let alone the consequences.
The rise in global average temperature of about 1.8 degrees Fahrenheit (1 degree Celsius) since pre-industrial times may appear negligible. But this seemingly tiny bulge has a huge impact on extreme heat emissions. BUT study released in the show “Nature, Climate Change” this week that “record climate extremes” will become seven times more likely in the next few decades due to global warming.
In practice, that means getting ready for more of what we’ll see this week. Even if the carbon dioxide pollution magically ends tomorrow, freeing me up so that I can finally fulfill my dream of opening a pizza parlor and punk rock music venue in a small mountain town where I can ski 100 days a year (it will work and it will great i just know it), the heat will not stop just like that due to climate change already embedded in the system. Like death this summer Forest fires, and destruction living world shows that we still have a ton of work to do to adapt to life on our hotter planet, beyond shutting off the fossil fuel tap.
