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:

The water level at a major river port in Brazil’s Amazon rainforest hit its lowest point in at least 121 years on Monday, as a historic drought upends the lives of hundreds of thousands of people and damages the jungle ecosystem.

Rapidly drying tributaries to the mighty Amazon river have left boats stranded, cutting off food and water supplies to remote jungle villages, while high water temperatures are suspected of killing more than 100 endangered river dolphins.

The port in Manaus, the region’s most populous city located where the Negro river meets the Amazon river, recorded a water level of 13.59 meters on Monday, according to its website. That’s the lowest level since records began in 1902, passing a previous all-time low set in 2010.

Some areas of the Amazon have seen the lowest rain levels from July to September since 1980, according to the Brazilian government disaster alert center Cemaden.
