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.

Power-sector CO2 hits ‘all-time high’ in 2024 despite record growth for clean energy. (www.carbonbrief.org)

Global power-sector emissions hit an “all-time high” in 2024, despite solar and wind power continuing to grow at record speed, according to analysis from thinktank Ember.

Emissions from the sector increased by 1.6% year-on-year, to reach a record high of 14.6bn tonnes of carbon dioxide (tCO2).

This increase was predominantly due to a 4% growth in electricity demand worldwide, leading coal generation to increase by 1.4% and gas by 1.6%.

Embers’ analysis finds that the increase in fossil-fuel generation was, in particular, due to hotter temperatures in 2024, which drove up electricity demand in key regions such as India.

Clean electricity generation grew by a record 927 terawatt house (TWh), which would have been sufficient to cover 96% of electricity demand growth not caused by higher temperatures.

Despite the increase in emissions in the short-term, this “should not be mistaken for failure of the energy transition”, notes Ember, but a sign we’re nearing a “tipping point” wherein changes in weather and demand hold a particularly strong sway.
