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:

New Stanford-led research traces a direct line from extreme weather to a massive dengue outbreak in Peru. The findings serve as a warning – and the seed of a possible solution.

In brief

  • Researchers traced Peru’s 2023 dengue outbreak to cyclone conditions, finding that 60% of cases stemmed from extreme rainfall and heat.

  • Climate modeling showed that conditions fueling the epidemic are now nearly three times more likely than in pre-industrial times.

  • Findings offer health officials quantifiable data to justify investments in mosquito control, vaccination, and urban flood resilience strategies.
