Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

People will propose pretty much anything because they don't want to see a rapid phase-out of fossil fuel use. The worse things are, the more out-there the things they propose get to be.

I'm fairly certain that there's not enough frozen water to completely submerge all land, if melted.

Haven't looked into estimates in about 10 years, but the estimates back then were just for significant lowlands being lost.

correct, the article saying we will lose coast population areas, which make up most of humanity. So we will need to move further inland. man island nations will be lost, Australia will also get an inland sea, Bangladesh will largely be lost, Netherlands will be gone, etc.

Humanity is an unredeemable shit hole.

Finish us off and make it quick

Maybe some kind of big boat that can hold a breeding pair of every animal on the planet could be of use.

This time, leave the mosquitoes off the boat.

They did everything they could.

But those fuckers just laid eggs. And lions had ticks.

That never happened though.

I guess fossile fuel profits will cover this?

Socialize the cost of saving ourselves while protecting the profits of these companies. God were fucked up.

“Fast-forward 1,000 years, the Earth will be geoengineered,” he said. “The entire climate will be regulated like a modern house—no question.” The climate may get screwed up in new ways as scientists attempt to turn the planet’s temperature dial down. But “if it survives, humanity is simply going to do this.”

That's a neat idea but at the rate we're moving we're going to kill ourselves off well before we figure out how to do anything approaching geoengineering effectively.

Imagine if our elected leaders were scientifically literate, and our population was educated

Then we could have these nice things

Thankfully, the Earth will go on but we won't. I welcome our Orcan overlords.

As long as Earth's biodiversity remains intact; the loss of mankind will go without remorse.

Even our precious cats and dogs will forget about us, after they eat us.

But you know who won't forget? Orcas.

Worst case scenario, the bacteria that live in volcanic vents on the floor of the ocean will repopulate the earth. Humans will be just a blip that showed up, made some plastic and then disappeared.

I think Humanity's extinction is extremely unlikely. That being said, life will become much more difficult for surviving humans.

At a MUCH lower population.

[–] whereIsTamara@lemmy.org 7 points 2 days ago

The answer is no.
