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.

This xkcd is what finally resolved the "is it us or natural variation" question for me: https://xkcd.com/1732/

It's always the rate of change.

I remember a few years ago people arguing the temperatures have changed before and that theres billions spent on climate change and it's all propaganda.

They wouldn't listen to the rate of change argument then or acknowledge the trillions spent in industries causing climate change. I'm not sure they've changed their minds still ( I refused to engage them any further) but this is the challenge - so many people believe what they want to believe and don't want the hard truth.

The Inconvenient Truth. That was so aptly named. Humans will do anything for the sake of convenience and climate change is quite inconvenient. Maybe if we make burning up the planet MORE inconvenient then it will change. Ridiculous taxes for carbon output sounds nice. Those tax dollars then spent on cloud seeding for the short term and carbon capture for the long term.

A lot of people love rationalising their own beliefs but hate reasoning out what's right and wrong. It makes me lose faith in humanity.

A lot? We all need to be aware that we are able to hold on to faulty beliefs. We are only human.
