Study weakens assumptions about forest carbon storage

Yahoo’s Ajit Niranjan reports that researchers studying 137 U.S. forest sites found trees often stopped growing months before photosynthesis ended. About 36% of annual carbon uptake in the eastern U.S. and 26% in California occurred after wood growth had stopped, suggesting absorbed carbon may go to shorter-lived uses rather than durable wood. The study warns Earth system models that tightly link photosynthesis and growth may overestimate future forest carbon sequestration as heatwaves and droughts intensify.

Why it matters

Forest carbon sinks underpin many climate pathways, so weaker long-term tree storage would raise pressure for deeper emissions cuts and more reliable carbon-removal strategies.

Louisiana enacts limits on climate-damages lawsuits

American Press’s Alton Wallace reports that Gov. Jeff Landry signed the Louisiana Energy Protection Act on Thursday, barring most Louisiana state-court civil suits seeking personal injury, property, or economic damages tied to greenhouse gas emissions and global climate change. The bill passed 31-3 in the Senate and 92-5 in the House, with exceptions for violations of emission caps, workplace safety standards, or explicit permit terms. Supporters framed it as blocking “climate lawfare,” while opponents including the Sierra Club Delta Chapter said it strips communities of legal accountability for sea-level rise and intensifying Gulf storms.

Why it matters

The law is a concrete state-level counteroffensive against climate accountability litigation and could become a model for other fossil-fuel-producing states.

Hungary’s Lake Velence approaches record low

Ynet Global reports that Lake Velence, Hungary’s third-largest lake, was recently measured at 56 cm in Agárd, only 3 cm above its 2022 record low after standing near 80 cm early in 2026. Experts warned that without significant rainfall the lake could fall by about 0.5 cm per day and reach roughly 30 cm by summer’s end, threatening boating, swimming, tourism, and waterbird habitat. Environmental Minister Laszlo Gajdos has met local NGOs, mayors, and water managers on restoration and water-quality measures.

Why it matters

The lake’s decline shows how drought, warming, wetland loss, and poor water management are converging into immediate ecological and economic stress in central Europe.

Worth noting

Wetland loss raises flood claims

The Invading Sea’s Lisa Sorg reports a Nature Water study estimating U.S. wetland destruction has increased flood insurance claims by $10 billion over 40 years, with unprotected wetlands providing $177 billion in flood-mitigation benefits.

U.S. solar overtakes coal

The Philadelphia Inquirer reports solar supplied 12.8% of U.S. electricity in May, surpassing coal’s 12.2% share for the first time and becoming the third-largest power source behind gas and nuclear.

IRS updates energy-community maps

McGuireWoods reports the IRS released Notice 2026-39 on June 10, refreshing clean-energy bonus credit eligibility lists and adding coal-closure tracts, including some retroactive eligibility to Dec. 31, 2022.

Still unclear

OPEN QUESTION

Will climate-litigation limits spread?

Louisiana’s new law explicitly draws from approaches in Oklahoma and Utah, raising the prospect of a broader state-level effort to narrow liability for climate damages.

OPEN QUESTION

How much forest carbon is durable?

If photosynthesis and wood growth are less coupled under hot, dry conditions, carbon budgets and offset strategies may need to distinguish more sharply between temporary uptake and long-term storage.
