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.

Computer models have been accurately predicting climate change for 50 years | A research scientist found that many 1970s-era models were ‘pretty much spot-on.’ Today’s models are far more advanced. (yaleclimateconnections.org)

Climatology and meteorology are separate disciplines with their own very different modelling. I studied the former way back when, and it wasn't even in the same department at my university (geography vs physics). Climatology is about long-term trends and focuses more on energy fluxes, general circulation patterns (both in the atmosphere and oceans), the hydrological cycle, the carbon cycle, etc. Meteorology is about the near-term. It focuses on the fluid and thermodynamics of specific weather systems, and how to process/interpret real-time data.

Thanks for the insight, friend!
