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.

In that context, Ho is sympathetic to the reasons climate scientists may not want to mention climate change, and to focus on something like air pollution instead. “It’s a safe thing to mention because it has nothing to do with climate change,” he says. “Air pollution is not one of the key words.”

“There’s a lot of uncertainty, there’s a lot of fear,” Ho adds. “And it shouldn’t be this way. Studying environmental sciences is about studying our life support system.”

"First they came for the climate scientists, and I did not speak out because I was not a climate scientist"

A hard truth for everyone in this thread: all of us who are doing anything less than actively resisting and defending them are complicit.

What are you, person reading this right now, personally going to do to help?

I've been to four protests so far, and the crowds are getting bigger. Not as big as they should be, but at the first protest there were half a dozen of us, and at the latest maybe a thousand.

Anyone is invited. It's invigorating to stand with other people who give a damn. Wear a warm jacket and leave your cell phone at home.

The truth les down in shame and failure. Defeated by the wealthy.

This should be their wakeup call to leave america

They need to leave if they are fearing for their lives

I can't hate on NOAA scientists (or CDC scientists) but the situation is intolerable, and they're in a really bad place. How do they keep those institutions going and also pick a fight with the deranged billionaires that can't wait to fire and sue them?

"alterations to atmospheric conditions"

12 syllables is more than MAGAts can figure out.

Despicable cowardice.

Polution never caused any climate change. We imagined it. Just like we imagine that 2+2=4. It's silly really.
