Climate - truthful information about climate, related activism and politics.

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.

We’re over-freezing our food. Turning up the temperature slightly could avoid 17 Mt of CO2 (www.anthropocenemagazine.org)

“This temperature corresponds to 0 degrees Fahrenheit, so it was “probably a round, easy number to remember”

That’s what Allouche and team will be working on next, as they build their research summary into a full report, to be published in September 2024. “These findings give good reasons for ‘3 degrees of change’ to be further explored,” Allouche says.

Looking at that rant. I'm pretty sure I have a lower carbon footprint than you.

In fact my decisions at work probably put me in a negative carbon bracket. I've certainly reduced many people's carbon footprint by more than my personal footprint can ever be.

Although I may make myself some steak and avocado toast now you've mentioned it, so the daily total will take a hit. Never had steak on toast before.

Both our carbon footprints are a rounding error. The only thing we can do to affect climate change is vote people in who will do something about it, protest.

I've not flown anywhere in 18 years. I might or might not fly somewhere on holiday soon. But if I do fly I'll sleep soundly.

You on the other hand have probably done nothing to reduce anyone's carbon footprint except your own and it's still multiple times the average of an individual globally speaking.

Use the power you have to do something, even if it's just voting. Don't rant at people on the internet who don't live in a hut on the equator living off their own small holding.
