Temperatures above 50C used to be a rarity confined to two or three global hotspots, but the World Meteorological Organization noted that at least 10 countries have reported this level of searing heat in the past year: the US, Mexico, Morocco, Algeria, Saudi Arabia, Kuwait, Iran, Pakistan, India and China.

In Iran, the heat index – a measure that also includes humidity – has come perilously close to 60C, far above the level considered safe for humans.

Heatwaves are now commonplace elsewhere, killing the most vulnerable, worsening inequality and threatening the wellbeing of future generations. Unicef calculates a quarter of the world’s children are already exposed to frequent heatwaves, and this will rise to almost 100% by mid-century.

If the world was warming even faster than scientists thought it would, seemingly jumping years ahead of predictions, would that mean even more crucial decades of action had been lost?

Yes. Yes it would.

    Rivers in Alaska have been running bronzish-orange... because the permafrost is melting.

    The 'perma' frost, is melting.

    That has huge amounts of methane locked up in at.

    Which is 8 to 80x more effective at being a greenhouse gas than CO2.

    And also ancient bacteria that could cause previously unknown kinds of diseases in wildlife and possibly humans, they now may or may not be seeping into the environment.

    ...

    We have already had a consecutive 12 months at or above 1.5C global average temps, as of last month.

    ...

    Shit's looking pretty bleak.

    Glaciers are reaching tipping points as well. Insane heat waves at both poles. It's over guys. Most poeple don't realize it yet but it's over. Those glaciers and poles took an entire iceage to form, and they are not going to come back.

    Definitely don't watch the Arctic Sinkhole documentary from PBS Nova if you like sleeping at night. It's all about the trapped methane in the permafrost and the trapped gasses under the permafrost. Shit is getting real scary. It wasn't even sensationalist.

    Capitalism is a death cult.

    Living and dying are the same process. You can't be born without dying. You could say biology condemns us all - very loosely - to a cult of death, as we must all participate.

    Capitalism is worse than that. Capitalism is an ideology of exploitation. I'm fine with dying, it's my fault for being born. I don't see why I must submit to exploitation while I do, temporarily, exist.

    climate scientists baffled by unexpected pace of heating

    Could it be ... fossil fuel producers lying about their output of greenhouse gases? Nah.

    There are also some comments about aircon not being a good answer if solely relied on, including:

    One of the key effects of heatwaves, which send demand for electricity soaring and cause extreme storms that stress electrical grids, is to cause blackouts. Blackouts mean no more air-con. A recent study suggested a blackout lasting just two days could hospitalise more than half of Phoenix residents and kill 12,000, mostly in their own homes. This is why the author Jeff Goodell warns of a “heat Katrina”: you thought the hurricane in New Orleans was bad?

    Further, what happens when everyone knows the power isn't coming back and instead the roads out of Phoenix all get backed up and people die in the heat of their cars trying to escape the heat of Phoenix. Because heat can kill a lot of vehicles, and a lot of people have ill-maintained vehicles, meaning roads being completely blocked from escape can happen fast.

    I really think Phoenix will become the first mass casualty event from climate change in the USA.

    That's one of those nightmare thoughts - when the power goes out, what do people usually do for a while? Wait for it to come back on. Someone is coming to fix it, right? Much of modern society is built upon such assumptions, and it mostly works. So I think you're right for some, but many would perish at home, trying to outlast the day (and what if the night doesn't cool?)

    I keep an old evaporative unit in the shed just in case. It only needs 70 watts and can thus run for quite a long time off a car battery or similar. Add a basic camping solar panel and you're more or less set for the day as long as you have water and don't live in a really high humidity place.

    The reason nothing will be done is because the only realistic option we have to save our planets ability to sustain life is economic degrowth.

    We don't have enough of the minerals we need to go fully nuclear or renewable and even getting close would use up vast amounts of the very same energy were looking to save in the first place.

    As the record levels of equality directly after ww2 showed, economic degrowth due to nearly all the men being at war, only results in the loss of the super rich which is why they'll never allow economic degrowth.

    We all work too much, produce too much and pollute too much. Worse, we're all forced to produce the very wealth thats used to force us into wage-slavery and kill our planet.

    The answer is and will always be the strategic refusal of labour, above what we need to survive and have a good quality of life. This, by default, will result in economic degrowth.

    Want to sit around and do nothing to save the planet? Well, now you can.

    While some argue that the world will soon pass the lower Paris agreement guardrail of 1.5C of heating above the preindustrial average, Schmidt says

    Unless 2022 - present turn out to be an anomaly, we already have.

    Late or not, we have to do all we can to stop runaway warming and ecological collapse. We know corporations and populations won't do anything voluntarily. That is why legislation is the only way. EU is taking the lead on this. I'm hoping world countries will follow.

    A lot of companies won't even allow remote work which would put a huge dent in commuter related pollution. Will that fix everything by itself? Nope, but it'd be a step in the right direction.

    But they won't even do THAT. This one little thing that'd be better for a lot of people and reduce car dependence related pollution for people in areas with little to no public transit access.

    I have a hard time believing the US will ever catch up to green initiatives since corporate lobbying pays corrupt assholes more...

    First you have to stop capitalist government

    lol yeah right

    But really though humanity is doomed unless we figure out a way to actually reverse it, because we wont do anything to stop it until its too late to stop (decades ago), so then we wont do anything until it begins creating worldwide problems, which is soon, so by then we will have to have a solution to reverse it.

    The new evidence that Greenland lived up to its verdant name in the not-so-distant past may represent an exciting scientific breakthrough, but it also heralds ominous possibilities for the future of humanity. Present-day atmospheric carbon dioxide levels are higher than they’ve been in millions of years; evidence of an ice-free Greenland in the more recent past means that it could take even less warming than once expected to deplete the continent’s all-important ice sheet. The frozen stronghold that covers Greenland contains enough fresh water to raise sea levels by 23 feet — a staggering volume that would reshape coastlines around the world.

    Impossible. Michael Crichton and the experts in Superfreakonomics assured us that scientists would be able to quickly implement geoengineering projects to reduce CO2 and cool the earth. /s
