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.

The Trump administration is dismantling a wide array of federal energy-efficiency programs at the same time that war in Iran is raising oil prices, climate change is fueling record heat that is driving up demand for air conditioning and new data centers are straining America’s electricity supply.

Funny what a bribe will do

The basic problem is that the precipitation models being used are historical averages, not forward-looking estimates. So they're always going to lag when constructed that way.

The areas burned by forest fires have nearly quadrupled since the 1970s, Mr. Flannigan said.

“It’s largely, not solely, due to human-caused climate change,” he said. “Warmer weather means longer fire seasons. In Canada, our fire seasons used to be fairly short, but they’re getting much longer. The warmer we get, the more lightning we see.”

The Bank’s new policy suggests that bonds linked to thermal coal are now too risky to sit on its balance sheet, as an international shift away from dirty fossil fuels towards greener energy could end up wiping out their value.
