Thawing permafrost turns Alaska rivers rusty
A study in Communications Earth & Environment links orange-stained streams in Alaska's Brooks Range to thawing permafrost. Researchers traced the change to two pathways: higher-elevation thaw exposing pyrite-rich rock and lower-elevation wetlands producing dissolved iron that oxidizes downstream. The iron can stay suspended for more than 100 kilometers, reducing water clarity and threatening algae, insects and fish gills.
Why it matters
It shows warming is creating diffuse, hard-to-stop water-quality damage across remote Arctic ecosystems.

The Cool Down coverageBangladesh lifts renewable targets and capacity buildout
Bangladesh's power minister told parliament on June 7 that the country's Renewable Energy Policy 2025 aims for renewables to supply 20% of electricity demand by 2030 and 30% by 2040. He said installed renewable capacity now stands at 1,781.09 MW, with 26 projects under construction totaling 1,172 MW and tenders out for another 665 MW by 2029. The policy covers grid solar, rooftop systems, floating solar and private-sector generation.
Why it matters
It gives Bangladesh a concrete renewable roadmap, but the current buildout still has a long way to go to meet the targets.

BSS coverageMalaysia's data centers drive record gas demand
Malaysia had 54 operating data centers by the end of 2024, with 81 expected by 2035 after approvals worth 144.4 billion ringgit from 2021 through mid-2025. The Grid System Operator said gas-fired generation surged 50.5% year on year in April to a record 5.54 terawatt-hours, while Peninsula electricity demand rose 11.5%. Officials linked the load growth to data centers, electrification, climate stress and electric-vehicle uptake.
Why it matters
It signals that fast-growing digital demand is already pushing Malaysia toward more gas generation, complicating its clean-energy goals.

Ancient thaw may have driven CO2 rise
A new University of Gothenburg study says post-Ice Age permafrost thaw may have released more than 300 petagrams of carbon and added about 52 ppm to atmospheric CO2, sharpening current thaw-risk estimates.

World Cup stadiums earn LEED status
AP reports 13 of 16 World Cup stadiums have now earned LEED certification, with solar panels, water savings and waste-diversion upgrades already in place before kickoff.

Odisha plans AgriPV policy by 2027
The state is signaling a formal push for solar panels over farmland, a concrete policy step that could expand dual-use renewable development if it is implemented on schedule.
Still unclear
OPEN QUESTION
How far will permafrost contamination spread?
The Alaska study says iron can travel more than 100 kilometers, but it remains unclear how many other Arctic river systems are vulnerable.
OPEN QUESTION
Can Malaysia avoid gas lock-in?
The reporting shows data-center growth is already pushing gas-fired generation higher, so the key question is whether new clean supply can catch up.
OPEN QUESTION
Will Bangladesh meet its 2030 target?
Bangladesh has a target and a project pipeline, but current renewable capacity is still far below what would be needed to reach 20% of demand.
