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.

A third of UK teenagers believe climate change is “exaggerated”, a report has found, as YouTube videos promoting a new kind of climate denial aimed at young people proliferate on the platform.

Previously, most climate deniers pushed the belief that climate breakdown was not happening or, if it was, that humans were not causing it. Now, the Center for Countering Digital Hate (CCDH) has found that most climate denial videos on YouTube push the idea that climate solutions do not work, climate science and the climate movement are unreliable, or that the effects of global heating are beneficial or harmless.

Researchers from the CCDH gathered a dataset of text transcripts from 12,058 climate-related YouTube videos posted by 96 channels over almost six years from 1 January 2018 to 30 September 2023. They also included the results of a nationally representative survey conducted by polling company Survation which found 31% of UK respondents aged 13 to 17 agreed with the statement “Climate change and its effects are being purposefully overexaggerated”. This rose to 37% of teenagers categorised as heavy users of social media, meaning they reported using any one platform for more than four hours a day.
