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.

Yes, this means a ton of carbon ends up in the atmosphere instead of in the trees. The right move would be thinning and prescribed burns, but this administration isn't going to do that.

In the past decade, China has regrown more than 70 million hectares of forest cover. The country has benefited greatly from solutions in biodiversity conservation, sustainable usage and climate governance, resulting in wetland and forest restoration that also combats desertification. (link to a WEF article on China's reforestation efforts)

... it has made "remarkable strides" in tackling the issue, said Xinhua, beginning in 1978 with the launch of the "Great Green Wall of China". Expected to continue until 2050, the "biggest tree-planting project in human history" will ultimately have created "88 million acres of forests in a wall stretching about 3,000 miles and as wide as 900 miles in some places", (article from The Week regarding anti-desertification efforts)

In November 2024, China's government reported that after 46 years of work it had finished the 3,000-kilometer green belt around the Taklamakan Desert. The country's forest coverage grew from 10% of the overall territory in 1949 to 25% in 2024 (this one's a link to the Wikipedia page for the Great Green Wall initiative, if you're interested)
