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.

  • Due to rising temperatures and climate change, small-scale coffee farmers in Colombia are increasingly planting cacao.
  • Cacao faces fewer immediate challenges compared to coffee, which is prone to pests and diseases, and can integrate well into agroforestry systems. However, agronomists warn that the switch to cacao can lead to clearing forests and increasing chemical inputs in order to expand existing plantations.
  • Higher profits, the high prices of cacao in the market, and the increasing expenses needed to manage coffee crops are also factors pushing small-scale farmers towards the switch.
  • Although coffee remains Colombia’s most important agricultural product, cacao is emerging not just as an alternative, but as a defining crop in Colombia’s evolving agricultural future, say agronomists.
