Summer Weather Is Getting 'Stuck' Due To Arctic Warming (theguardian.com)
An anonymous reader quotes a report from The Guardian: Summer weather patterns are increasingly likely to stall in Europe, North America and parts of Asia, according to a new climate study that explains why Arctic warming is making heatwaves elsewhere more persistent and dangerous. Rising temperatures in the Arctic have slowed the circulation of the jet stream and other giant planetary winds, says the paper, which means high and low pressure fronts are getting stuck and weather is less able to moderate itself. The authors of the research, published in Nature Communications on Monday, warn this could lead to "very extreme extremes," which occur when abnormally high temperatures linger for an unusually prolonged period, turning sunny days into heat waves, tinder-dry conditions into wildfires, and rains into floods.
One cause is a weakening of the temperature gradient between the Arctic and Equator as a result of man-made greenhouse gas emissions. The far north of the Earth is warming two to four times faster than the global average, says the paper, which means there is a declining temperature gap with the central belt of the planet. As this ramp flattens, winds struggle to build up sufficient energy and speed to push around pressure systems in the area between them. As a result, there is less relief in the form of mild and wet air from the sea when temperatures accumulate on land, and less relief from the land when storms build up in the ocean.

Amazing how many ppl really do not look at reality. Good posting.
I prefer the "u" in honour as it seems to be missing these days.
Considering how many people in the US believes science is fake, how about setting up a lot of very large fans and tell people they will be used to circulate air and it will slowly help eliminate the heat waves.
But remember keep the real use of the very large fans secret
Which means they have data to back it up. They may be wrong, of course, in which case their assertions will be disproved
I'm glad to see you accept the dogma: there can be no incorrect interpretation of the data.
"First they came for the slanderers and i said nothing."
Bullshit. Using modern farming methods, hydroponics, aquaponics, etc, we can grow enough food to feed the entire planet, just in the borders of the US ALONE. So don't tell me that 8 billion people is unsustainable. That's horseshit.
Chas - The one, the only.
THANK GOD!!!
Per GDP is about the worst possible measure.
You like to praise America for heading in the right direction, and blame China for the wrong direction. But if you did measure against GDP China would be getting better much faster than America is. China is going in the right direction faster than America is. Why aren't you arguing China is cleaner than America? OOPS.
You keep telling us you care about the direction and not the level, which is stupid. Because China is growing at 6+% every year. According to your theories, they could increase their CO2 5% every year and you would praise them for heading in the 'right direction'.
You wouldn't because you are an anti-China troll. But if you were consistent instead of entitled, you would be praising China.
