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.

relevant bit (I think, I didn't read the entire thing):

And while many experts have been cautious about acknowledging it, there is increasing evidence that global warming has accelerated over the past 15 years rather than continued at a gradual, steady pace. That acceleration means that the effects of climate change we are already seeing — extreme heat waves, wildfires, rainfall and sea level rise — will only grow more severe in the coming years.

This is nothing new though. Climate Scientist have ALWAYS been fearing a runaway effect. It has a wiki page and all. The author isn't wrong, but it's click bait. It's not telling us anything new.

I think the difference is that, at least when I took a class on this (coincidentally about 15 years ago), we talked a lot about how there was likely to be a runaway effect. This article is saying that the climate measurements from the last 15 years provide evidence that the predicted runaway effect is, in fact, happening.

I would like to buy 50 years time please 🥺, if people can wage war, build monuments, AI and trains all in under 30 years then we still have some what a slim chance of working through some of the climate change problems without committing mass suicide of some sort

It may be click bait, but given the topic and urgency, I want as many unique clicks as it can get.

All that's going to do is burn the credibility of the author.

Regardless, no one is going to read this and suddenly change their mind, because we don't have an education problem, we have a culture problem.

You're right. Nothing will work and we should stop trying.

I thought we knew this? I remember hearing that we're just now feeling the effects of greenhouse gas emissions from the 80s, and emissions have drastically increased since then.

Good. Burn this mother fucker DOWN. This is what you wanted people. Soak it in, bitches.
