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.

I read somewhere that it is normal of humans to overestimate progress in the short term, and underestimate it in the long term.

That gives me hope, assuming we have a long enough term for all this progress to manifest.

I think we have underestimated how much progress has been made on killing the planet.

“I’ve come to the conclusion that hope has to be a strategy”

How bleak is that...

Tacitly admitting that we're going to have to get really lucky because without a heretofore unseen ability to change there's nothing coming to save us.

I wouldn't say it's about being lucky, so much as realizing that if you simply stew in your own gloominess, you get nothing done. It takes actively going out there and changing the world.

This. Who else is going to do it? There are lots of ways to contribute.

No matter how bleak things seem, if it is still possible to turn things around, we need to keep fighting.

Here are some pretty amazing comebacks from US football:

This coming year is a major election year in the US. If all of us in the US give it everything we've got, we could really ramp up turning this around. Let's treat 2024-11-05 with the same seriousness as d-day.

There's some good information in this article, but I would have appreciated it being a little less of an ad for a podcast.

The title implies that we're going to hear from scientists about their opinions, but all we actually get in its body is a single quote from one scientist as the literal tagline. Talk about clickbait.
