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.

âoeThe Trump administration disbanded a 15-person advisory committee that helped communicate scientific climate change findings to businesses and government officials, making data from the National Climate Assessment "more accessible and useful to private sector/civic organizations and state/municipal governments for their use in planning and decisionmaking."â
Iâ(TM)m guessing trump doesnâ(TM)t notice the weather because his head is up heâ(TM)s ass.
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...
That's right! WE DO!
I'm not a fan of China, but we can't outsource all our dirty shit to China, and then point to China and blame only them.
Every piece of cheap crap we consume, is US killing ourselves by ruining our home (the planet).
(And we buy cheap crap because we let the leeches take by far most of our money in-between sale price and salary. With salaries based on work time times skill alone, and making profit, as opposed to actually earned money, a crime, like theft and robbery, we could afford things that don't ruin the planet. ... Buut I bet most people are already too mentally disabled nowadays, to not buy the cheap crap anyway "BECAUSE MOAR".)
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.
Have all nations drop their emissions together.
I agree, but that's not a "how". That's not an engineering plan.
We need to get to the levels of Denmark and Finland .
Okay, let's look at how Finland does it.
https://en.wikipedia.org/wiki/...
They get 25% of their electricity from nuclear, 20% from hydro, and... 22% imported? That doesn't sound like a plan. That's just exporting your emissions.
Let's look at Denmark.
https://en.wikipedia.org/wiki/...
They get 75% from natural gas, and 25% from wind. Not a bad plan in my opinion. Though I would like to see them adopt some nuclear power like Finland. Natural gas produces about half the CO2 output of coal, and wind a tiny fraction of the CO2 output of natural gas.
To get an engineering plan start with the CO2 output of the different energy sources.
https://en.wikipedia.org/wiki/...
The best three on that list is hydro, nuclear, and wind.
Let's look at the energy sources with the best energy return on investment.
https://en.wikipedia.org/wiki/...
If we toss out the carbon heavy sources we again get the same top three, hydro, nuclear, and wind.
Let's look at the safest energy sources.

Wow, look at that, the same three come out on top, hydro, nuclear, and wind.
Cheapest energy?
https://en.wikipedia.org/wiki/...
Well, the pattern is broken, geothermal comes out on top. What's the next three, again tossing out the carbon heavy sources? Hydro, nuclear, and wind.
I believe we have a start on an engineering plan for lowering the worlds emissions. Let's start with hydro, nuclear, and wind. If you want to sprinkle in some geothermal and solar then that's fine by me. Just so long as we start with hydro, nuclear, and wind. You know, like Denmark and Finland did.
I am armed because I am free. I am free because I am armed.
The problem is it won't be 30C year round. It'll be 40C in the summer and -20C in the winter and the variations will be erratic and unpredictable. Summer will start in January one year and July the next, it'll rain all year long one year and then won't rain again for two more. The worst kind of situation imaginable for food production.

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

while America comes down.
So? What the hell is the point of that? We can criticize when we pass them.
Until then you're bitching about someone using less than half the amount of CO2 per person than we are.
The population size does not matter.
It absolutely fucking matters. We are all in this together, and China puts out a relatively small amount of CO2 for the amount of people they have. We are the offender, not them. Now could that change some day? Sure. But I'm not going to point fingers at them as long as we're the person driving a Suburban, bitching about the Honda drivers wasting gas because there's so fucking many of them.
China has emitted the MOST as a nation since the time of christ, 1850, 1950, last 10 years, etc. They continue to grow their emissions.
So? What the fuck is your point here? Your argument is the stupidest fucking thing I have ever heard.
You're literally making the argument that we should draw arbitrary lines around groups of emissions and judge them on the whole instead of the content. You are terminally stupid, dude.
Only an idiot would sit in this shit and continue to let it happen.
Only a complete fucking moron would sit there from his castle and complain about the masses of poor people below him hoarding money.
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.
