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:

The U.K. government on Tuesday introduced new rules requiring developers to install heat pumps and solar panels in all new homes across England, in policymakers’ latest response to the economic fallout of the Iran conflict.

U.K. ministers say the Iran war and the largest supply disruption in the history of the oil market reinforces the need to leverage clean power as an energy security tool.

The Future Homes Standard — a set of new-build regulations for England from 2028 — will establish requirements to ensure homes are built with on-site renewable electricity generation, the majority of which is expected to be provided by solar power.

The rules will also see homes built with low-carbon heating, such as heat pumps and heat networks.

The government added that plug-in solar panels, which homeowners can install on balconies, would be available within shops over the coming months.

Summary: Investors bet Iran war will boost Chinese renewables demand

Since the US-Israeli war against Iran began on February 28, investors have been pouring money into Chinese renewable energy stocks, anticipating that the resulting oil shock will accelerate global demand for green energy — a sector China dominates. The CSI Green Electricity Index has risen 6% in March, with major players like GCL Energy Technology surging 48%, while the broader Shanghai Composite has fallen 8%.

The thesis is straightforward: energy security fears, combined with growing distrust of US reliability, are pushing countries — particularly in Europe and Southeast Asia — to accelerate renewables buildout, nuclear power, and grid resilience. ASEAN's foreign minister explicitly called for faster renewable energy deployment in response. Chinese EV makers and battery producers are also seen as beneficiaries, as the oil shock prompts consumers to reconsider petrol vehicles.

Goldman Sachs and several investment managers note that China's dominance in solar, wind, batteries, and EVs positions it well for what one analyst calls a "multi-year renaissance in renewables." Sectors previously suffering from oversupply are now expected to become profitable as export demand rises — making the current market correction, in the view of some fund managers, a buying opportunity.

A pub in California is pulling carbon dioxide from the air to carbonate pints. If the business model works, it could give the broader carbon-capture industry a boost.

The Arctic sea ice, which helps store nutrients that sustain the crustaceans whales eat, is melting earlier in the year — disrupting the food chain whales depend on.

“These feeding areas that they migrate such long distances to are warming four times as quickly as the rest of the planet on average, and that’s having a major impact on their prey availability,” Stewart said.
