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.
I haven’t seen anything from climate scientists that agrees with that level of doomerisim. They want to keep fighting against every 0.1C of warming we can, because that’s a worthwhile fight. Succumbing to climate nihilism is unhelpful, unscientific, and a self-fulfilling prophecy.
I can at least alleviate your worries of ancient bacteria.
Even our weakest antibiotics could wipe them out as they have evolved zero resistance to it. That’s assuming they can even infect humans in the first place.
I’m no microbiologist but couldn’t the ancient bacteria hybridize with modern bacteria to develop antibiotic resistance similar to a wolf and dog hybrid having a tolerance to humans?
Have you ever looked up how long it takes for bacteria to evolve resistance after exposure to an antibiotic?
2-3 years… Yeah…
More concerning is a virus in my opinion. Jumping species is common and it’s the novelty to the immune system thats the danger. How much damage would an influenza strain from 3-4000 years combining with modern strains cause?
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.
it’s my fault for being born.
is it? I don’t recall ever asking to be born, i’m pretty sure that just kind of happened.
I don’t recall ever asking to be born
Who would do the asking and what would be providing the answer?
Just because you can’t recall it doesn’t mean it didn’t happen. As a spermatozoon, you eagerly swam towards that egg, then that egg could have chosen to abort at any time. Yet here you are alive. You chose to be here. Deal with it, accept it and move on with your life.
That’s because you’re a sinner and exploiting sinners isn’t to be punished, but praised. Exploit your fellow sinners, make them toil in suffering and you too shall redeem salvation in the form of stock options and tax evasion.
And yet its the least worst functional economic system we currently have…
climate scientists baffled by unexpected pace of heating
Could it be … fossil fuel producers lying about their output of greenhouse gases? Nah.
oh it’s much worse than that. not that it isn’t also that and them doing that isn’t the reason we didn’t get started mitigating this shit seventy years ago when we wouldn’t have needed substantial sacrifices.
see, climate scientists are scientists. that means they can only announce what they KNOW, what they can be very confident in, what IS in the data.
the thing about climate change is; it’s full of unknowns, most of them bad. so they can’t say “we have had this many unknown unknowns pop up and fuck our shit up, and expect (range of numbers) more”, because that’s predictive, and it’s useful, but its not SCIENCE, because science is inherently a very conservative bedrock-of-knowledge try-not-to-give-permission-to-fuck-up paradigm of knowledge. that’s not a flaw generally, it’s why we can trust it and why it’s hard to compromise, but generals and combat sports athletes do not choose their actions scientifically-it’s too fucking slow, and they would all fucking die/get punched in the face and lose literally every single time.
so while they have calculated the known dangers of the path we’re tumbling down, they can’t really include the assumption that there was a military base here during a civil war 20 years ago, and both sides in that conflict really liked land mines. they can only point to specific mine fields they know about, even if that’s way less than any other site that was involved in that conflict.
so however bad a climate scientist says it’s going to be, dude, holy shit, it’s going to be so much fucking worse. however much time they say we have, we have less than that. how much worse? how much less? no fucking clue.
no way to know unless we sit on our asses and let it happen, at which point everyone dies.
Yes, can’t emphasize this enough. It worse than predicted. And it’s all exponentially getting worse.
Aren’t climate scientists also measuring atmospheric composition levels around the world to track this, usivg satellites and whatnot? I.e., do they really rely that much on self reported data?
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.
EDIT: Obligatory Peggy Hill. Peggy gets it.
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?)
And then their food goes bad. Three days of starvation is all it takes to eat cake.
Lots of cars > lots of traffic > stopped cars > radiators don’t cool > cars break down > roads blocked
Car radiators have fans. They can idle indefinitely. You’re more likely to eventually run out of gas.
Edit: oh you mean because of the heat. I don’t think that’s going to be an issue, ambient temp is still going to be far below the roughly 200°F of an engine.
Most people buy the cheapest car batteries they can get. As a Floridian I can tell you, the heat destroys these things faster than most people realize. Everyone is already strapped for cash so they’re going to be driving around with batteries that barely start their car for months before it finally leaves them stranded.
That’s when it becomes Rita as opposed to “heat Katrina”.
For folks who don’t remember/know about Rita because they didn’t live through it, less than a month after Katrina a record-breaking cat 5 hurricane was heading for Texas. Everyone still had Katrina on their minds and panicked. Millions of people (literally estimated as 2.5–3.7 million) evacuated, or tried.
The highways out of Houston came to a total standstill. About 100 people died before the storm even hit land because of the evacuation. And then the hurricane itself was nbd; the evacuation was literally the worst part.
Realistically it’ll be when people can no longer insure their homes when we see the first mass migrations. Florida is already at the point where only state insurance will cover hurricane prone areas, and it sounds like that currently costs $7k/year. Anyone have any bets for if it’ll be the southwest suffering more frequent more severe fires that gets it first or Florida and neighboring states from more severe hurricanes?
Frankly, I am amazed it has not already happened in Houston, Dallas, San Antonio, or Austin. The power grid here in Texas is a disaster and the weather conditions are unforgiving. At least in the desert you can do evaporative cooling. That doesn’t work where its hot and humid.
It has. Some weak ass cat-1 hurricane killed like a dozen people in TX earlier this year. The winds didn’t harm anyone directly but it knocked out power for a few days in places. That’s all it takes when temps are well above 100F.
Yeah, I was in that storm. We were without power for 3 days. Fortunately it was not over 100f that during that stretch but It would have been so much worse if it had been. I personally know people who were without power for almost 2 weeks after it came through. Centerpoint was negligent in maintinging their equipment, right of ways, and getting their crews where they should have been.
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.
A significant amount of greenhouse gasses are emitted because of air conditioning. It’s a feedback loop.
I said that air con made global warming worse on Reddit a few years ago, got massively downvoting.
THE TRUTH HURTS!
I get downvoted for asking for cars with manual roll up windows because spending electricity on rolling up a car window is negligent when its easy as fuck to do by hand.
But if you add up all the electricity used since automatic windows were invented, power used to roll up and down windows, in aggregate its no small amount. It adds up.
But nooooo manual roll up windows is a step too far.
Wait really? Do you mean by the electricity generation or by a refrigerant process?
I know those processes are inefficient and create overall heat in the system as they can’t create cool but only push heat, there should be no green house emission, just heat generation.
Are you saying extra heat will stay in the atmosphere? That’s not good but it’s not the same as carbon which allows heat to build up.
The power used by AC is responsible for ~3% of global emissions. I can’t find data about the impact of refrigerants ATM, but I assume it’s significant because of their extremely high “global-warming-potential.” I’m guessing a significant amount of emissions come from the manufacture of refrigerants, and a significant amount of refrigerants leak out of systems when they fail (or are improperly disposed of).
wow have we procrastinated real climate action long enough yet?
Doubt procrastination will stop even after 60-70 becomes a new high in those countries and people start dying en masse
