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.

As international leaders, corporations and NGOs gear up to discuss efforts to tackle global warming at the upcoming United Nations Climate Change Conference (COP29) in Baku, Azerbaijan, residents in a crucial region for the climate crisis show they have very different priorities.

Many politicians who openly oppose conservationism were elected. Two of the seven Amazon states’ capitals elected candidates supported by former President Jair Bolsonaro, a climate denialist who empowered illegal miners and land-grabbers during his government from 2019-22.

“The rise of the far right is very visible in the Amazon states,” Wendell Andrade, public policy specialist for the Amazon at the Talanoa Institute, a Brazilian think tank committed to climate policy, told Mongabay...

... The centrist and right-wing parties also dominated the elections in the municipalities targeted by the federal government as a priority to control deforestation in the Amazon. Of the 70 municipalities, 69 were decided in the first round, and only two went to left-wing parties, which historically favored environmental conservation in Brazil, according to news outlet ((o)) eco.

The 2024 elections happen during the Amazon’s worst drought ever. Large rivers, like the Madeira, Amazonas, Negro and Purus, reached their lowest levels ever, isolating communities, leading to food and water shortages and damaging local economies. Fire outbreaks have burned the Amazon in Brazil and the neighboring countries. This year’s extreme drought followed another harsh dry season in 2023, which was 30 times more likely due to climate change.

“It’s a development agenda that is bringing a lot of destruction, and yet a large part of the population prefers these candidates,” Maureen Santos, coordinator of policies and alternatives in FASE, a Brazilian nonprofit that helps to promote local and community development, told Mongabay. “We need to study this phenomenon to tackle it more concretely in the next elections”...
