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.

I would like to address the doomers.

Just stop. All you are accomplished is dissuading people from trying. Even if we fail, some of us would rather go out feeling good about ourselves knowing that we actually tried. If we succeed, I want to be on the right side of history. If you want to drive a canyonero through a drive through to buy a double cheeseburger on your way to the airport to fly somewhere for a shopping trip: please keep it to yourself.

  • There is still hope
  • Most people want action. I can cite more than one source.
  • Things are starting to turn around. Not as fast as we need to, but we are seeing change
  • Some of us are parents and have a reason to fight with all we have
  • If things get bad, our kids will actually want to have a relationship with us if we cared enough to try
  • Many things that help are economically better on the micro and macro scales

Doomers are the fossil fuel industry's best friend-- even more than the deniers are. If enough people succumb to it, they don't even have to pay lip service to the problem. Doomerism means you can continue to pollute and not even try.

Not zero,but so far below what is neededthat 'doomer' is a ridiculous characterisation of 'realist'. Anyone who thinks we're dealing with the problem is delusional.

You're confusing cynic with realist. The realists are the climate scientists, who have yet to say humanity is doomed.

Oh hanity will live on. We're a pretty adaptable species, but not as numerous or as comfortable.

Or, we could try our best to prevent it on the chance that billions of people don't have to die.
