Could the Earth's Record Hot Streak Signal a New Climate Era? (msn.com) 170

South America's Amazon River has reached its lowest level since measurements began, according to the Washington Post, while temperatures "hovered above 110 degrees Fahrenheit" for nearly a week as April began in the capital of Mali. "Nights offered little relief, with temperatures often staying above 90 degrees..."

"An overtaxed electrical grid sputtered and shut down," they add, and "dehydration and heat stroke became epidemic... At the city's main hospital, doctors recorded a month's worth of deaths in just four days. Local cemeteries were overwhelmed." The historic heat wave that besieged Mali and other parts of West Africa this month — which scientists say would have been "virtually impossible" in a world without human-caused climate change — is just the latest manifestation of a sudden and worrying surge in global temperatures. Fueled by decades of uncontrolled fossil fuel burning and an El Niño climate pattern that emerged last June, the planet this year breached a feared warming threshold of 1.5 degrees Celsius above preindustrial levels. Nearly 19,000 weather stations have notched record high temperatures since January 1. Each of the last ten months has been the hottest of its kind.

The scale and intensity of this hot streak is extraordinary even considering the unprecedented amount of greenhouse gases in the atmosphere, researchers say. Scientists are still struggling to explain how the planet could have exceeded previous temperature records by as much as half a degree Celsius (0.9 degrees Fahrenheit) last fall. What happens in the next few months, said Gavin Schmidt, director of the NASA Goddard Institute for Space Studies, could indicate whether Earth's climate has undergone a fundamental shift — a quantum leap in warming that is confounding climate models and stoking ever more dangerous weather extremes.

But even if the world returns to a more predictable warming trajectory, it will only be a temporary reprieve from the conditions that humanity must soon confront, Schmidt said. "Global warming continues apace."

Will this summer's La Niña cool things off? More atmospheric research is underway, and "Schmidt says it's too soon to know how worried the world should be," according to the article. But he does raise this possibility. "What if the statistical connections that we are basing our predictions on are no longer valid?"

"It's niggling at the back of my brain that it could be that the past is no longer a guide to the future."

    I've long said the biggest problem for humanity is death, as it has been since we've been humans, and the biggest problem with death is dictatorship and corruption slowing progress.

    Putting it in terms of gw because that's the current concern in the west, puts the cart before the horse for major problems of humanity by several orders of magnitude.

      For them, yes. But as with anything, nothing is 100%. Give enough warmth and it won't matter how amazing your electrical grid is, it'll always win.

      Oh absolutely. But the solution isn't power grids and generators, the solution is stopping our unbounded disposal of CO2 directly into the environment. We either need to reduce the CO2 being released altogether or find some means to stop dumping it directly into the air.

        Incorrect, the solution is certainly power grid improvement.

        Your solution is for the far long term and will do nothing to solve the issues within anyones lifetimes.

        It's like trying to address the number of fatalities on a road by workin

        Bro, they were talking about shit like this in Mother Earth News almost 50 years ago. If nothing was done by now, what makes you think anything will be done until we are literally dying by the millions or billions?

      It not only puts the cart before the horse, but gw efforts are rife with corruption and a lack of accountability. They're basically government slush funds for corruption and spending malfeasance. If you're looking for cost effective energy, pre-subsidized cost of "green" technology power (batteries, wind, and solar) isn't it.

  • I recall some rule about questions in news headlines, that if there is a question then the answer is most likely no. I believe this rule applies here.

    Extreme heat is undoubtedly deadly but even more deadly is cold. Humans are a tropical species, we tolerate heat much better than cold. What makes headlines though is that heat often kills quickly with heat stroke and such while cold kills slowly by wearing on the immune system and such so people die of pneumonia or such at relatively random intervals.

      >Humans are a tropical species, we tolerate heat much better than cold.

      The majority of our population centres were in no danger of becoming so cold as to be uninhabitable. We're looking at a lot of currently inhabited areas that will have extended periods of fatal wet bulb temperatures.

      > Is a warmer planet all that bad?

      We lose our existing coastal infrastructure (which will create new pollution problems). We will see climate zone shifts causing mass population migrations which will likely lead to wars. With more energy available, storms will become stronger. Given the climate change is happening more rapidly than evolution can generally produce adaptations, we can expect a fairly long period where mass extinctions outnumber migrating species or new species filling abandoned niches, which will almost certainly mean fewer food options for us. The elevated CO2 levels will impair human cognition indoors where concentrations are higher and more difficult to dilute to safe levels due to the external elevated levels.

      Yes, a warmer planet is 'all that bad'.

          Ice ages don't freeze the entire planet. The last 'snowball Earth' was 635 million years ago. Since then it's north of 37deg N in the northern hemisphere and barely touches the southern outside of Antarctica itself.

          Ice ages aren't accompanied by higher CO2 levels than the human brain is evolved to tolerate.

          The next glacial period won't happen for another 50,000 years while we're dealing with heating issues right now.

          But you are correct, it's not up for debate - AGW is a far greater threat than an ice age.

          • I didn't say they freeze the entire planet. I didn't say they are accompanied by higher CO2. Nice strawmen. All your irrelevant blabbing doesn't change the fact that humanity was almost wiped out in the last ice age approximately 70K years ago. What I said is a mundane fact we carry in our genetics you can look it up rather than just making shit up.

            You're either stupid or a liar if you claim to not understand ice ages are more dangerous to life.

              I find it amazing that around that time, we all agree that Humans started wearing clothes.

          I searched; I didn't find anything to support your claim with regards to humans. Are you referring to some ancestor of humanity?

          Also I don't think Ice ages are considered the greater threat. The rate of change for the next predicted ice age is slow enough that it's easier to modify society. 50,000 years for an ice age gives us more time than 100 or so years for large changes we will see with hu

            Well seeing as there were just about 1000 humans left alive because of it I say they are the greater threat.

            • It's very easy to find. BUt the date/time given is incorrect.

              That's what I orginally found, but the date matters. 900,000 years ago those couldn't be "humans" since we currently believe Homo sapiens showed up around around 300,000 years ago.

        • This is probably true, but completely irrelevant to the current discussion. An ice age is not happening any time in the near future, whereas abnormal warming is happening now and needs to be dealt with. This is like when someone is attacked by a pitbull, and you say that if they were instead attacked by a tiger, or a t-rex, that would be more dangerous. Probably true, but a tiger or t-rex attack is a pure hypothetical, whereas the pitbull attack is happening and needs to be dealt with now.

      • Yes, a warmer planet is 'all that bad'.

        Evidently, nobody fucking cares. They will care when they are gasping for breath, but until then, we will continue blowing CO2 into the atmosphere unabated. The only thing many people will be gasping with their last breath is, "we made lots of profit!".

        "You dead bitch. You dead. Why are you still breathing?"

    • We can adapt to the new climate like humans have done since humans were human

      The thing is this kind of warmth. If it continues at the pace it is going, there isn't an adapt. We just simply cannot adapt to where this is heading and no technology will change that. We can leave the planet maybe, but we don't even have that technology. We can visit space, maybe another planet, but we have zero ability to *live* in space. So if this continues, and maybe it won't who knows, but if it *does* continue at the rate we are seeing, dying is the only outcome. There are 0% chances of any ot

  • Then we will have a nuclear winter and cool this hot rock down. Just thinking outside the box.

    • We don't even need that. Just have another major volcanic eruption at least on the scale of Mount Tambora (there are several volcanoes in Indonesia capable of this right now) and watch Earth's climate drop by over one degree Celsius and Europe wondering why it froze over in winter.

    El Ninho is a ocean current pattern in the pacific. It hardly has any influence on the other side of the planet.
    This current El Ninho is roughly one year old.
    It is completely implausible that this summer already an La Ninja pops up.
    That will take 5 to 7 years. And there is no guarantee that after an El Ninho you get La Ninja. You easily get 2 in a row.
