Good news, everyone! If we mandate solutions and spend the time and money, we might not kill ourselves off!

snippets:

Two and a half years ago, when I was asked to help write the most authoritative report on climate change in the United States, I hesitated. Did we really need another warning of the dire consequences of climate change in this country? The answer, legally, was yes: Congress mandates that the National Climate Assessment be updated every four years or so.

Thanks to recent scientific advances, we can now link climate change to specific extreme weather disasters, and we have a better understanding of how the feedback loops in the climate system can make warming even worse.

And while the report stresses the urgency of limiting warming to prevent terrible risks, it has a new message, too: We can do this.

The conversation has moved on, and the role of scientists has changed. We’re not just warning of danger any more. We’re showing the way to safety.

It would be a shame to squander this opportunity. So I don’t just want to talk about the problems anymore. I want to talk about the solutions. Consider this your last warning from me.

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.
