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.

China and the EU are expected to publish a joint statement committing the two regions to more ambitious plans for cutting emissions ahead of the UN COP30 summit in Brazil, in an effort to galvanise action on climate amid geopolitical tensions

The EU, typically one of the most ambitious parties at COP talks, faces a backlash from member states over efforts to commit to a high level of cuts. EU governments including France and Poland have said the bloc should not agree to more stringent targets unless support for its flagging industry and households was greater.

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.

China needs to cut steel output from the coal-powered blast furnace process by more than 90 million metric tons from 2024's level to achieve its green steel target this year, researchers said in a report published on Tuesday.

The global steel industry is responsible for around 8% of the world's carbon dioxide emissions and China accounts for more than half of global steel output.

China has lagged far behind its global peers in terms of electric arc-furnace steel share. The average share is around 30% globally, 71.8% in the United States, 58.8% in India and 26.2% in Japan, [a report by the Helsinki-based Centre for Research on Energy and Clean Air] said.

From 2021 to the first half of 2025, China's blast furnace capacity utilisation rose from 85.6% to 88.6%, while electric-arc furnace utilisation fell from 58.9% to 48.6%, it added.

[...]

"A credible strategy to curb emission-intensive production and rein in excess capacity would not only tackle the sector's structural issues but also ease global tensions," said Belinda Schaepe, an analyst at the Helsinki-based centre.

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%.
