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.

Experts welcomed the structural shift to an absolute cut but judged the ambition insufficient for a 1.5°C pathway. “Anything less than 30% is not aligned with 1.5 degrees,” said Lauri Myllyvirta of the Centre for Research on Energy and Clean Air (CREA). Greenpeace East Asia’s Yao Zhe said the plan “still falls short,” even for tempered expectations. Belinda Schäpe, a China policy analyst at CREA, framed the pledge as politically cautious and argued China’s clean-energy boom could still deliver reductions of 30% or more by 2035 if current trends hold. In her words, today’s announcement should be viewed as the floor, not the ceiling.
