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:

  • Endangered angelsharks have been served to schoolchildren in the Brazilian state of Rio Grande do Sul for years, as well as in hospitals, clinics, shelters and other public institutions, Mongabay has found.
  • We identified 52 tenders totaling more than 211 metric tons of “peixe anjo,” a common name for angelshark, issued by the state and city administrations since 2015.
  • As endangered species, angelsharks can’t be caught in Brazil, but imported specimens can be traded legally. Brazil’s IBAMA enforcement agency has requested the environment ministry close this exemption, which some call a loophole.
  • After we asked them for comment on past procurements, the state government and two municipal administrations said they wouldn’t buy angelshark anymore.
