00:00Scientists are issuing a stark warning today.
00:03The heat dome gripping 30 U.S. states is not just a weather event.
00:07It is evidence of a permanent and dangerous shift in how our atmosphere behaves.
00:12NOAA describes this pattern as an omega block,
00:15a massive high-pressure ridge that traps heat like a lid on a pot.
00:19And here is what makes this moment extraordinary.
00:22Right now, both the United States and Europe are simultaneously locked under omega block heat domes.
00:29Scientists say that would have been virtually impossible before human-driven climate change.
00:34AccuWeather analysts are warning that these events will become more frequent,
00:38more intense, and more lethal,
00:40particularly for American cities in the Midwest and Great Lakes regions
00:44that have historically never needed to plan for extreme multi-day heat.
00:48This week, over 230 million Americans are experiencing exactly what experts have warned about for years.
00:55This is the new reality.
00:58And the data says it will get worse.
00:59And the data says it will get worse.
