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.

That's because a warmer atmosphere can hold more moisture. That extra water vapor means storms can drop more rain than in the past. Today, the heaviest rainstorms in Texas drop about 20% more water than they did in the late 1950s, when the planet was significantly cooler, according to the National Climate Assessment. And extreme rain in Texas is expected to get much more frequent in the coming decade, as the climate warms even more, according to a 2024 report by the Texas state climatologist.

For every degree Celsius that Earth’s atmospheric temperature rises, the amount of water vapor in the atmosphere can increase by about 7%, according to the laws of thermodynamics.

I've been through three once in a hundred year storms in the last 5 years. Buckle up we haven't seen anything yet.

We just had +100F temperatures where I am. We had wildfires in the hills south of the city a year ago. I live in fucking Boston. Everyone is going to be impacted over the next few decades, and no one will be as prepared as they think

Around the country

When are you yanks going to learn. It’s like the Middle Kingdom all over again but in a really poorly made version of English with weird accents and strange measurement units.

It’s 2025. It’s okay to say world even if you can only name 2 other countries.

Its worldwide, but national outlets with limited global reach dont put that in the headline
