Biden says global warming topping 1.5 degrees in the next 10 to 20 years is scarier than nuclear war (www.cnbc.com)

What Biden has done is to cut the issuance of drilling leases to the minimum required by law, pass the Inflation Reduction Act, enact a regulation to force vehicle electrification, and similarly force fossil fuels out of most power plants.

What Biden has not done: stop issuing drilling permits or impose export restrictions on fossil fuels. The former has some serious limits because of how the courts treat the right to drill as a property right once you hold a drilling lease, and the latter is simply untested.

Didn’t we just hit 1.5C today?

We're still some years from hitting an ongoing sustained average of 1.5°C above what it was in the late 1800s. That's what people mostly talking about when they say 1.5°C

[-] bouh@lemmy.world 7 points 1 year ago

This year will be above 1.5°C. Which means we did reach that.

What you're talking about is the average of yearly average temperatures. But it's not what we're looking at. We've never seen earth average temperature above +1.5. And averages don't move much. I don't care if next year will "only" be +1.49...

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.
