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.

Good to know. Doesn't help that the current administration in the USA is actively hostile to renewable energy, which would offset this problem significantly if we hurried up and built out renewables at a much faster rate.

This would also create employment, to which the current regime is also actively hostile.

tl;dr: It's alarmingly large and rapidly growing.

I wonder where all the money is coming from. It's got to run out at some point.

Nixon way back in the 70s decoupled the dollar from gold, it’s been coke snorting ever since.

Helps that not a single teacher dares to explain where money actually comes from.

Tldr; it’s never running out. This hype needs to survive till the next’s hype is ready.

is there a comparison between blockchain energy use and AI related energy use?

I appreciate that they make the key point that AI is definitely here to stay. It's not about stopping it, it's about dealing with the fallout of the switch. To do that we need solid data.

Exactly, the environment changes and we must adapt to face the new changes.

The problem is that misinformation from both Pro-AI and Anti-AI groups makes it harder to obtain solid data.
