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.

He mentiond climate change and pollution , well worth a read IMO

“The future is really daunting for people in the Maldives … the climate emergency is an existential threat that overshadows all the other issues.”

over 40 million people have died of air pollution since I became special rapporteur in 2018, yet I just can’t get people to care.

“I can’t get people to bat an eyelash. It’s like there’s something wrong with our brains that we can’t understand just how grave this situation is.”

“I think the right to a healthy environment is actually the foundation that we require to enjoy all other human rights. If we don’t have a living, healthy planet Earth, then all the other rights are just words on paper.”

If we don’t have a living, healthy planet Earth, then all the other rights are just words on paper.

I get his bemusement, just here in Australia, 11,000 die from air pollution from cars annually, another 20,00 are hospitalised annually. The numbers are beyond horrendous and yet, on a scale of 1 to 5 fucks given, it's 0

Also carbon-driven climate change is the largest tragedy of the commons possible (at our current tech level) and humans have never successfully conducted the level of cooperation required to solve it.

Closest analog is CFC-driven ozone layer decay. That was mostly solved because the solutions aren't that painful . I don't really care that all aerosol cans work a little worse now that we don't put CFCs in them. Climate change isn't that . The solutions require deep, painful, and expensive change. Easier to just pretend everything is fine and ignore it.
