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:

China needs to cut steel output from the coal-powered blast furnace process by more than 90 million metric tons from 2024's level to achieve its green steel target this year, researchers said in a report published on Tuesday.

The global steel industry is responsible for around 8% of the world's carbon dioxide emissions and China accounts for more than half of global steel output.

[...]

China has lagged far behind its global peers in terms of electric arc-furnace steel share. The average share is around 30% globally, 71.8% in the United States, 58.8% in India and 26.2% in Japan, [a report by the Helsinki-based Centre for Research on Energy and Clean Air] said.

From 2021 to the first half of 2025, China's blast furnace capacity utilisation rose from 85.6% to 88.6%, while electric-arc furnace utilisation fell from 58.9% to 48.6%, it added.

[...]

"A credible strategy to curb emission-intensive production and rein in excess capacity would not only tackle the sector's structural issues but also ease global tensions," said Belinda Schaepe, an analyst at the Helsinki-based centre.
