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.

An international research team has successfully drilled and retrieved a 9,186-foot-long (2,800-meter-long) ice core from Antarctica that dates back 1.2 million years. (www.cnn.com)

Hey, I've seen this one.

A prehistoric virus is gonna infect someone with coldness until a plucky US-Marshall-turned-sherrif saves the day with his science-mined friends and colleagues.

the end of man may very well be embedded in one of those 2800 one-meter long popsicles.

How do you pull out a 2.8 km core? Surely it gets cut into chunks on the way out?

Edit: yeah, they cut it into 1 meter lengths as it comes out. so this will be 280 pieces.

Each meter of ice can contain as many as 13,000 years of climate data, said Julien Westhoff, chief scientist
