Climate - truthful information about climate, related activism and politics.

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 Oregon charts are surprising as I understood most of them don't have AC out there.

In the Willamette Valley (main population area) most people have some type of air-conditioning. Just a window unit on some of the older construction. Around 20% of the homes have no cooling.

The state is pushing for heat-pump adoption on all newer builds or furnace replacements. Both for energy savings and to meet the cooling needs from increasing temps.

That has been changing rapidly throughout the region. There's been enough extreme heat waves over the past decade that AC is becoming normalized. Just about any new build is going to have it now. Especially in the Portland or Seattle areas where most people in the region live, the Summers now often also have smoke from forest fires so opening a window for a breeze may not be ideal.
