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.

The global landscape of energy investment is experiencing a significant shift, with coal-fired power plants receiving unprecedented attention despite international climate commitments. Global approvals for coal-fired plants have reached their highest level since 2015, marking a dramatic reversal of the anticipated decline in fossil fuel investments.

China stands at the forefront of this coal renaissance, having commenced construction on approximately 100 gigawatts of new coal plants in 2024 alone. This massive expansion represents a capacity equivalent to the entire existing coal fleet of countries like Germany and Japan combined.

[...]

In 2024, a “resurgence” in construction of new coal-fired power plants in China is “undermining the country’s clean-energy progress”, says a joint report by the Centre for Research on Energy and Clean Air (CREA) and Global Energy Monitor (GEM).

[...]

This surge in coal investment presents a stark contradiction to global climate goals. According to the International Energy Agency (IEA), coal remains the largest source of energy-related emissions, accounting for a staggering 45% of the global total. The continued expansion of coal capacity threatens to undermine international efforts to limit global warming to 1.5°C above pre-industrial levels.

Steel is something like 8% to 11% of total CO2 emissions, so if true, this will have a huge impact.

The move is part of the EU's "simplification" agenda to slash red tape for industries who say that complex bloc-wide legislation means they struggle to compete with rivals in China and the U.S., where President Donald Trump is slashing regulation.

The shift to sustainable aviation fuel is still minuscule, while growth in passenger air travel is drowning out any climate gains so far. For example, despite IAG’s world-leading status, cleaner fuel accounted for only about 1.9% of its overall fuel consumption last year, and its emissions from fuel combustion still rose by 5%.
