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.

Snow and ice are a way of life here. See how a lost winter upended that. Wisconsin’s Northwoods are normally a playground of snow and ice right now. But life here has become unrecognizable. (wapo.st)

It is the second straight winter of extreme Wisconsin weather, but at the other end of the spectrum. A year ago, parts of the Northwoods were buried under more than 100 inches of snow, over twice their average snowfall.

Those sorts of swings are to be expected as the climate warms, Vavrus said. As temperatures warm, on average, precipitation is becoming more intense because warmer air holds greater moisture.

“We have to adapt not only in a change in the average, but a change in the variability,” Vavrus said. “We have to be prepared for everything.”

So much beautiful snow photography (stock footage etc) comes from Wisconsin. It's well known for snow and snow research. Sad to see the landscape changing over there
