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.

  • The U.S., the largest importer of wildlife products in the world, brings in nearly 10,000 species of plants and animals into the country legally, some of which have a high potential to become invasive species.
  • A recent study assessed these imported species and identified 32 as having the highest risk for becoming invasive, posing threats to local ecosystems and to human health.
  • These include venomous reptiles like puff adders and spitting cobras, and freshwater fish; similar species that have already established themselves as invasives have wrought havoc on native wildlife and caused widespread economic harm.
  • The researchers say their findings can help authorities regulate the imports of such high-risk species and add them to watchlists to prevent them from becoming invasives.
