How are you coping with climate change?

Ask Lemmy@lemmy.world – 99 points – 3 months ago

This has been a doozy of a year. And it's the best year so far blah blah. So how are you all coping? Does it hit anyone else like a bolt of lightning that probably I - we - won't die of old age?

I am educated in science and I do not think humanity will survive, no. Most megafauna will probably die out. There are ~10 planetary boundaries and we've crossed a lot of them. Earthquakes and volcanoes will start picking up. AMOC collapse could be as soon as 2025.

Uh, what? Earthquakes and volcanoes due to climate changes?

Earthquakes and Volcanic Activity has been tied to sea level and air pressure changes. So one leading theory is that climate changes will more likely than not cause more activity, however the last year has shown no such changes yet Source on last year activity

AMOC collapse could be as soon as 2025.

No. I also read that. There was a prediction that AMOC collapse might be inevitable by 2025 and take a couple centuries to happen.

We have pretty good evidence the currents are slowing, but no real data to predict if and when it might stop. A couple researchers made a prediction that is not currently accepted by the field. It’s just pretty dire, but would affect a few generations from now even if true

No, it won't take a couple of centuries to happen, you misread. The collapse will most likely happen before 2050 according to new research which speeds up the timeline on the old research. The various environmental fields do actually agree on this and it's accepted.

The impacts of an AMOC collapse would leave parts of the world unrecognizable.

In the decades after a collapse, Arctic ice would start creeping south, and after 100 years, would extend all the way down to the southern coast of England. Europe’s average temperature would plunge, as would North America’s – including parts of the US. The Amazon rainforest would see a complete reversal in its seasons; the current dry season would become the rainy months, and vice versa.

That means the collapse will happen, with immediate consequences as well as consequences that won't stabilize for over 100 years, not taking into account other destabilizing forces. Like can you read?

Nothing you quoted even says it will happen, much less that the effects will be immediate

Lol

Then you should recall that some of the largest megafauna ever lived for tens of millions of years at much higher temperatures(and therefore sea levels)

At higher temps that changed over thousands of years gradually. This is not that. And that's even if "high temp" was the ONLY planetary boundary being crossed. It is not. There are numerous SIMULTANEOUS extinction events happening. And we know megafauna isn't surviving this time because we are in the middle of a major extinction event already. Millions of sea life and millions and millions of birds and insects are dead already, from being boiled alive in the ocean to starvation to pollution to bird flu.

Extinction of individual unfit species doesn't mean the total collapse of life.

Individual unfit species like ALL birds and ALL insects and ALL sea life and ALL fish? Not including ALL corals and ALL trees (forest fires). Lol what's left, really? In terms of biomass, that's like, most of it.

That we are in an extinction event is widely known in the scientific community.

^There, read up. Sorry to break the news to you.

like ALL birds and ALL insects and ALL sea life and ALL fish?

Where does it say that???

Not including ALL corals and ALL trees (forest fires).

Coral life is dying for the most part, but not everywhere

Global forest area loss has significantly slowed, and seems to be continuing to go down

Wildfires are not a significant risk to global forest coverage.

Annual wildfire area is declining year over year, and is overwhelming a risk to savanna, shrublands, and grasslands

What I mean is that ALL species in those categories are affected. It's not 1 or 3 species, it's affecting literally every species across those Phylla. Your claim was that is was a few unfit species. It's not, it's all the species.

Several tree species in the US are undergoing extinction due to forest fires, including the Redwoods: https://www.washingtonpost.com/climate-environment/2022/08/23/extinct-tree-species-sequoias/

The coral thing you posted is kinda laughable, sorry to be rude when you're facing total annihilation of most life on this planet, but I have been chuckling about that for a couple of minutes. https://www.noaa.gov/news-release/noaa-confirms-4th-global-coral-bleaching-event

"From February 2023 to April 2024, significant coral bleaching has been documented in both the Northern and Southern Hemispheres of each major ocean basin," said Derek Manzello, Ph.D., NOAA CRW coordinator.

“Climate model predictions for coral reefs have been suggesting for years that bleaching impacts would increase in frequency and magnitude as the ocean warms,” said Jennifer Koss, director of NOAA’s Coral Reef Conservation Program (CRCP).

The 2023 heatwave in Florida was unprecedented. It started earlier, lasted longer and was more severe than any previous event in that region.

NOAA made significant strides to offset some of the negative impacts of global climate change and local stressors on Florida’s corals, including moving coral nurseries to deeper, cooler waters and deploying sunshades to protect corals in other areas.

(Do you see how NOAA was unable to fix the root cause of bleaching at any level? This is our governments failing us)

Global forest area LOSS has slowed. Meaning how much we are losing is going down, but we are still losing it.

Boreal forests in regions all over the world have been experiencing the worst wildfires in recorded history in 2023, according to new research.

The total wildfire emissions for 2023 is estimated to be almost 410 megatonnes, the highest on record for Canada by a wide margin, according to the Copernicus Atmosphere Monitoring Service dataset, which provides information on the location, intensity, and estimated emission of wildfires around the world. The previous annual record was set in 2014 at 138 megatonnes of carbon.

It isn't even close to the end of 2024 fire season so I gave an article from 2023.

What I mean is that ALL species in those categories are affected.

Effected yes, going extinct? No.

We are specifically talking about if all life will be wiped out.

Yes, it will be. Where is your confusion here?

Stuff was not as bad before.

Now stuff pretty bad.

We have done nothing to deal with that and in fact are still just making stuff worse (maybe some stuff is not making stuff worse at the same rate as before)

Stuff gets worse exponentially

Already extinction in the millions and billions is happening

Will extinct more next year at an exponential rate, bc we have done nothing and all solutions will take decades

All those species are affected meaning they are dying.

Ecology means that's bad, stuff relies on each other

Chemistry means that's bad, stuff relies on each other and certain Temps to happen

All around all science says, it's bad

Nothing you've shown says that 100% of species will go extinct xd

Okay, well you're free to believe as you'd like. I'm fine with agreeing to disagree. The math checks out really clearly to me, "exponentially getting worse" is pretty clear in meaning.

If a population exponentially grows does that mean it will continue infinitely? Why would the reverse be certain to be different?

If a population is given infinite resources, sure, theoretically. The energy that comes from the sun is cumulative and may as well be considered infinite since the sun isn't going out any time soon. Did you really think that was a gotchya?

Look at every other planet. That ours happens to be energetically at a temp to support life is the exception. The rule in the universe is that it's literally unlivable for us everywhere else we know of. Literally. This is pretty much it.

Can you please elaborate on what you mean by "educated in science"?

I have taken a variety of science classes, especially in biology but also in chemistry, engineering, and physics, at undergrad and masters level at multiple decent universities.
