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.

A new term has entered the lexicon of Chinese economic analysis: involution. In Chinese, this term translates to “nei-juan”, a concept that refers to a state of “excessive and self-defeating competition among Chinese companies for limited resources and opportunities”. In this situation, intensifying effort yields diminishing returns for all participants [...] This phenomenon is best captured with a theatre metaphor: in a crowded theatre, one person stands to get a better view, forcing everyone else to stand as well. Ultimately, no one’s view improves, but all are exhausted from the extra effort.

[...]

China’s involution issue is ... a structural outcome [China's] supply-side, investment-driven model [that] systematically suppresses household income to subsidize production and leads to chronic overcapacity and destructive competition.

[...]

The trigger was the collapse of China’s real estate sector in 2021–2022. As property developers cut investment sharply, Beijing faced a serious threat to GDP growth. Because the growth model could not tolerate a decline in investment, the state redirected capital away from real estate and toward manufacturing. This shift was politically necessary to stabilize headline growth, but it was not driven by market demand.

[...]

[Chinese] provincial and municipal governments, under pressure to meet [Beijing's] growth targets, offered subsidies, cheap land, tax exemptions, and financing to attract investment. This led to duplicated projects and rapid oversupply.

[...]

The surge in supply collided with structurally weak [domesstic] demand. Consumer confidence deteriorated after 2020 due to job insecurity, falling property values, and rising precautionary savings. The same growth model that fuels overcapacity also depresses consumption by transferring income from households to producers. A limited social safety net further encourages precautionary saving, reducing the effectiveness of short-term consumption subsidies.

[...]

The polysilicon industry, a key upstream input for solar panel manufacturing, illustrates the scale of the problem. After the property collapse, in less than four years, the top four Chinese producers managed to add the capacity equal to two-thirds of the total global capacity ... It puts China as world-leading in the industry, supplying about 95% of the world’s polysilicon supply. The problem is that this is roughly double the global demand. This overload of supply drove capacity utilization below 40% in 2025, forcing producers to sell panels at prices below their variable costs.

[...]

Beijing’s “anti-involution” campaign represents a serious attempt to curb the most damaging effects of excessive competition. Measures include revisions to the Pricing Law, coordinated production cuts, and sector-specific interventions such as plans to retire excess polysilicon capacity ... However, these policies treat the symptoms rather than the cause. They reduce capacity in one sector without changing growth incentives, simply shifting overinvestment elsewhere. Indeed, while investment slows in EVs and solar, capacity expansion is accelerating in petrochemicals, another sector already facing involution.

[...]

Two reforms are essential [in China]: strengthening domestic demand and accepting lower investment-led growth ... The supply-side reforms must be paired with strong fiscal support for households. In a liquidity-trap environment, fiscal policy, not monetary easing, must play the central role in restoring confidence and consumption.

[...]

In parallel, China must reduce its reliance on manufacturing and infrastructure as primary growth engines. This would require Xi Jinping to confront an uncomfortable political trade-off: accepting lower GDP growth targets in order to pivot the economy toward services, consumption, and household income growth.
