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.

After four years of rising destruction in Brazil’s Amazon, deforestation dropped by 33.6% during the first six months of President Luiz Inácio Lula da Silva’s term, according to new government satellite data.

From January to June the rainforest had alerts covering 2,650 sq km (1,023 sq miles), down from 4,000 sq km during the same period last year under former president Jair Bolsonaro. This year’s data includes a 41% plunge in alerts for June, which marks the start of the dry season when deforestation tends to jump.

Or negative, we need to reexpand forests to capture carbon

And to foster new wildlife!

I'm hoping we can leverage drone technologies to really get reforestation projects underway

The big issue with reforestation is usually not some technical thing; it's getting the people who actively graze or grow crops on land to let it be reforested.
