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.

    Now, come back when you have an actual, scientific ENGINEERING PLAN to combat it in a way that doesn't involve

    • Destroying the planet's economy
    • Call for massive depopulation of the planet
    • Cause us to revert to shivering savages living in caves

    Until then, POLITELY FUCK THE HELL OFF!

    More than 1/3 of co2 being emitted is from china. In addition, china is by far the largest in terms of total emissions across all time frames. Now china not grows their own, but also continues to grow co2 emissions in other nations. The only place for Putin to increase oil/nat gas is china, who will likely do to Russia, what they are doing to Venezuela.

      Which is actually pretty impressive, don't you think?
      They emit literally 1/3rd the CO2 per person as the United States, and have over 4 times the population.

      In addition, china is by far the largest in terms of total emissions across all time frames.

      Well ya, they have the largest population on the planet shit-for-brains.

      So do people capable of even rudimentary logic.

    Your reading and other comprehension skills baffle me ...

    Your desire to follow me around and "correct" me is baffling.

    You show us a link about Denmark: https://en.wikipedia.org/wiki/...
    And then you claim, they generate their electricity They get 75% from natural gas, and 25% from wind.
    Could you have the dignity to READ your links? And comprehend them?
    Denmark produced 2014 47% of its energy by wind, solar and hydro. 7% not 75%, by gas.

    Yep, I confused the installed capacity with production, so sue me. Here's another site I was able to find with more recent data.
    http://www.world-nuclear.org/i...

    They show about half the electricity from "thermal" (fossil fuels in various forms), and about half from wind.

    I don't bother to debunk your other links ... no idea what your secret agenda is.

    I have no "secret agenda", I thought I was quite clear on my agenda. I want to see solutions rather than just complaints on the problem. Solar is not a solution, it can be part of the solution but it is not a solution on it's own. Hydro, nuclear, and wind are solutions. The main part is that hydro, nuclear, and wind must ALL be included in the solution. Without all three the solution falls apart.

    Oh, and natural gas. It's going to be difficult to go all hydro, nuclear, and wind at once. Until that happens we should use lots of natural gas to get off of coal and oil.

    So far everything you posted about nuclear energy, solar and anything related to power was basically wrong.

    Oh, really? Sure would be nice if you posted some links to sources once in a while. Or, just once. Anyone can claim someone is wrong. I can claim you are wrong. Without something to back that up it's just talk.

    Seems to me that if you picked up on my "oops" on Denmark that you took some time to look over what I linked. And when you found something wrong you jumped all over it. Since that was the only thing you commented on being wrong tells me you could find nothing else wrong.

    Wait, maybe I do have a "secret agenda". It's to get under the skin of people like yourself.
