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 growing body of scientific evidence now suggests that, due to rapidly increasing greenhouse gas emission levels in the atmosphere, the world is on track to overshoot the Paris Agreement’s 1.5C target within the next three years, pushing the planet beyond a critical threshold faster than previously feared.

The dire warning comes from the most up-to-date assessment of the state of global warming, led by a group of international researchers and published in Earth System Science Data earlier this month. The report was signed by over 60 scientists across 17 countries.

  • Combu Island is already warmer and drier than 40 years ago, leading to declining yields in açaí crops.
  • The Guamá River surrounding Combu is now experiencing unusual and prolonged periods of rising salinity, which impacts water quality and affects local aquatic life.
  • Local islanders expect COP30 to move beyond rhetorical discussions on measures to mitigate the damage that has already been done to places like Combu.
