California revises cap-and-invest amid market volatility
California Air Resources Board revised proposed updates to the state's Cap-and-Invest program in response to economic uncertainty and volatile carbon market conditions, the Mercury News reported. The changes double a manufacturer decarbonization incentive fund to $4 billion, add roughly $800 million in compliance support through 2030, and keep emissions caps in place through 2045 while changing how allowances are handled after 2030. Industry and environmental groups remain split over whether the revisions protect refineries and consumers without weakening climate targets.
Why it matters
California's carbon market is one of the most consequential state climate policy tools in the U.S., and these revisions will shape industrial decarbonization incentives and compliance costs.

Mercury News coverageAgulhas eddies cool shelf seas, increase stratification
A new study of two years of mooring observations across the Agulhas Current at 34° S finds that stronger eddy activity cools adjacent shelf waters while increasing stratification in the current core. The researchers report that submesoscale frontal eddies dominate in linear current states, while meanders trigger alternating barotropic and baroclinic conversion; across the full record, heat and salt move toward the current core. Phys reported the work as evidence that intensifying ocean eddies are amplifying climate extremes along coastal seas.
Why it matters
It identifies a concrete ocean-dynamics mechanism that can reshape coastal temperatures, nutrient transport, and ecosystem stress as currents intensify under climate change.

Phys coverageGeorgia Power approves customer-led clean energy program
Georgia Power's Customer-Identified Resource program was approved by Georgia public service commissioners with bipartisan support and is expected to open this summer, Grist reported. The program lets electricity customers propose and finance clean energy projects tied to Georgia Power's system, either directly or by funding projects that were not selected through the utility's standard bid process. Supporters say it could accelerate clean deployment and reduce pressure for new gas generation as demand rises, including demand from data centers.
Why it matters
It gives large electricity customers a new route to build or back clean power inside a fast-growing utility territory.

Still unclear
OPEN QUESTION
Will California's revisions still hit 2030 targets?
The new compliance support and manufacturer incentives may improve political durability, but the carbon-market changes still need to preserve emissions reductions.
OPEN QUESTION
Do Agulhas eddy changes generalize elsewhere?
The paper suggests similar behavior should emerge in other subtropical western boundary currents, including the Gulf Stream, if eddy activity keeps intensifying.
