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.

    Wrong. Wrong. Wrong. Wrong. Wrong. I was just looking over all your assertions, and they are almost 100% wrong. "They" are most of the world's scientists, not some shady organization backed by Al Gore. https://climate.nasa.gov/ https://europeanclimate.org/

    Which means they have data to back it up. They may be wrong, of course, in which case their assertions will be disproved -- which is the thing that distinguishes the scientific consensus from religious opinion.

    The advisory committee was scheduled to come to an end. Each person had a five-digit salary and they only met a few times for meetings lasting a few hours during Obama's second term. Their funding was not explicitly renewed.

    Nothing of value was lost and Trump did not "disband" the committee. Trump was not involved at all.

    We have talked about this at length on slashdot more than once. Leave it.

    *as an aside, like many sated the last time this was discussed, I would looove to have a job paying me 30k to show up for an afternoon meeting once every six months, have no responsibilities and no expectations. Fantastic!

    Volcanos would like to have a word with you outside sir....

    Horse shit, they would.
    Volcanoes eject about 200 million tons of CO2 from the crust annually, human fossil emissions are about 24 billion. They're not even the same fucking sport. Quit lying.

    Last word? If your argument relies on your being full of shit to make sense, that makes you a fuckwit.

    Your reading and other comprehension skills baffle me ...
    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.

    There is a nice table at 25% of the page, just scroll there.

    I don't bother to debunk your other links ... no idea what your secret agenda is. So far everything you posted about nuclear energy, solar and anything related to power was basically wrong.

    Three times now you have claimed this with nothing to back it up. where this shows clearly America was far far worse going back to 1900.

    Data from 1900-2004 supports such an argument, when you keep in mind the size of countries' populations. The US has the biggest historical share (314,772m metric tonnes of carbon dioxide), while European countries such as Germany (73,625) and the UK (55,163) cast a shadow over developing nations such as India (25,054), Brazil (9,136) and Indonesia (6,167). China is on 89,243.

    And that isn't even considering America is a quarter the size of China.
