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.

Air-Conditioning Use Will Surge in a Warming World, U.N. Warns | By 2050, electricity use for cooling could double, driving up the greenhouse gas emissions that cause warming. (www.nytimes.com)

Yeah, there's a transport/home energy use tradeoff there.

Any city that still hasn’t got their shit together & built a cycling infra in the next ~5-10 yrs should be ghost-towned. Those cities are not participating in society. Nonetheless, the burden of a car commute on the environment is shadowed by the cost of heating and cooling a house for a full day.

Heating an cooling impact is incredibly dependent on location and season. Work-from-home is lower energy at least seasonally in a lot of places.

The problem is corporations are happy to send people home all year round just to cut their own energy costs, esp. in the non-temperate climate periods when the collective on-site energy efficiency is most needed. That’s what the corporate bottom line dictates. Staff are happy to take that lifestyle at the cost of energy inefficiency. There’s no policy or mechanism anywhere to reverse that and discourage teleworking when the outdoor temp is outside temperate ranges.
