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.

You really sure you wanna ring that bell? Because when Norway is 30C all year round, that means that a good portion of the planet is going to be uninhabitable. So there will be billions of people, many of them with guns, who will come for their piece of Norway. And you can't stop them all, especially if the famous winter slog that caused the Russians so much trouble before isn't there any more. Some people think Scandanavia has african migrant problems now, if what you wish for comes to pass there'll be several hundred million migrants coming your way...
It's always been a money grab - but when half of the top ten companies get their $1.4 trillion a year from oil and gas, it's pretty obvious where the climate money trail really leads.

Judging from most of the people I've met so far in my life, I have to deduce that God is an asshole.

Maybe you can lead the way. Switch off your computer and never turn it on again
You can't solve the Tragedy of the Commons by personal actions.
The composition of the atmosphere has been changed a fraction of a tenth of a percent.
Imagine we separate the atmosphere in different layers of pure gases. The pre-industrial amount of CO2 would then be equivalent to about 3 feet thick layer of pure CO2. The current layer of CO2 would be about 4 feet.
The fact that this layer of CO2 is very thin compared to the much bigger amounts of nitrogen and oxygen is irrelevant. Nitrogen and oxygen don't block IR.
