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 wonder if Trump would be able to run again if he lost in 16. His first term really allowed him to consolidate his power. Basically reshape the RNC, make Fox News his personal megaphone, and make all the wealthy donor contacts that fueled the next 6 years.

However it's not like he was a runaway train that first primary. It was a highly contested field that he probably only came out of because there were so many options. So if he never wins that first election, I wonder if he'd have the momentum to go into a second one or if people would view him as a loser. It's hard to say. So much of what we just take as common knowledge about him now was relatively unknown back then.

Would pundits have spent the intervening years just tearing him apart? Would the people he beat in that primary be circling like wolves? With the party brass view him as the reason they lost and try to distance themselves? It's really hard to say.
