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.

Nuclear winter will definitely cool the planet, especially if hundreds of bombs are used ... but it will mean turning the planet into a snowball.

Nuclear winter will mean destroying most or all plant life for years or decades or even a century. Many people will die either from the bombing or the radiation but the majority will die slow deaths from starvation years after.

Sure there may be some wealthy important people that will hold out in bunkers and underground shelters but once their food supplies run out, they'll have to come out, and when they do, they won't find anything. The survivors will have to raise new generations with far less, even if they do survive living in an irradiated landscape which won't be safe for hundreds of years.

The planet will definitely be cooler .... but it won't be liveable for humans.

This isn't a race to save the planet by cooling it off, the planet's fine. It's dealt with disasters and changes far more destructive than us.

We need to do something about the climate to save ourselves and our species. Nuclear war places us in as much danger of extinction as doing nothing about climate change.

Did I seriously need to put a /s at the end of my comment?

In this day in age ... Yes, it's almost required.

I felt like you were being sarcastic but I've encountered more than enough people in my life to know that there are people out there who fully believe in what you sarcastically said.

I can't tell any more who is being sarcastic, who is ignorant, who is willfully antagonistic or who is sarcastic anymore. There are far too many people out there who state unrealistic ideas who find like minded people to reinforce one another.

Whenever I write a sarcastic comment on a forum like this, no matter how clearly it is for me or even others .... I always note (sometimes very clearly) that I'm being sarcastic.

There are people out there who will understand your sarcasm.

And there are people out there who will turn your sarcasm into prophesy or gospel.
