As climate change strikes with ever greater ferocity, five henchmen dominate the news: Storm, Flood, Heat, Smoke and Fire.
During the first 6 months of 2021, there have been 8 separate billion-dollar weather and climate disaster events across the United States. The U.S. has sustained 298 weather and climate disasters since 1980 where overall damages/costs reached or exceeded $1 billion (including CPI adjustment to 2020). The total cost of these 298 events exceeds $1.975 trillion. The total cost over the last 5 complete years (2016-2020) exceeds $630.0 billion — averaging more than $125.0 billion/year — both new records.
The NASA Worldview satellite image below shows smoke traveling from the West Coast to the East Coast of the U.S. on July 26, 2021.

As the temperature difference between the North Pole and the Equator narrows, the wind flowing north on the Northern Hemisphere slows down, which changes the Jet Stream, resulting in more extreme weather events, including heatwaves and fires.

Ominously, the MetOp-2 satellite recorded methane levels as high as 2839 ppb at 469 mb on July 30, 2021 pm, as the image on the right shows.
The image underneath shows how methane levels over the Arctic Ocean at 293 mb on August 1, 2021 pm, while a mean global methane level of 1940 ppb was recorded.
This global mean methane level of 1940 ppb translates – at a 1-year Global Warming Potential (GWP) of 200 – into 388 ppm CO₂e, i.e. almost as high as the mean global carbon dioxide level is at the moment.
Methane levels are already very high over the Arctic, so additional methane erupting there will be felt most strongly in the Arctic itself, thus threatening to trigger even further methane releases.
