Satellite megaconstellations may be creating an unexpected climate tradeoff

Researchers warn that megaconstellation launches may claim a growing share of launch-related climate impact.
The key concern is soot that can remain in the stratosphere for years.
The issue broadens space-policy debates beyond debris and astronomy impacts.

Wildfire risk is now spreading to cool climates like the Scottish Highlands and Irish uplands

Wildfire Risk Is Moving Into Europe’s Cooler Uplands

Researchers say wildfire risk is expanding into cooler landscapes in Scotland, Northern Ireland, and Ireland.
The analysis links the shift to both climate conditions and long-term land-management changes.
Reduced grazing and less active upland management can allow more flammable vegetation to build up.

Heat waves are now everyday disasters. Governments need to do more to protect people

Heat Is Becoming a Daily Disaster, Not a Seasonal Emergency

A 10-day heat event across 12 major European cities in summer 2025 was linked to 2,300 deaths.
The source says 1,500 of those deaths were attributable to climate change amplifying temperatures.
Existing heat action plans often fail to account for inequality in cooling access, work conditions and social support.

Melting of Greenland ice sheet could release methane 'fire ice'

Ancient Greenland methane release offers a warning for a warming Arctic

Researchers linked large Melville Bay seafloor pockmarks to past methane hydrate release.
The proposed trigger was glacial meltwater after the last glacial maximum.
Methane hydrates hold vast carbon stores and can be destabilized when cold, high-pressure conditions change.
The finding adds a new potential methane-release pathway to Arctic climate risk discussions.

Melting of Greenland ice sheet could release methane 'fire ice'

Greenland Meltwater Study Raises New Methane Release Concern

A Greenland study points to glacial meltwater as a new methane-release mechanism.
Researchers found 50 large pockmarks in Melville Bay seafloor sediments.
Sediment cores suggest methane hydrates were disturbed after the last glacial maximum.
The findings raise concern about future climate feedbacks as ice sheets melt.

In 2025 landslide caused by the retreating South Sawyer Glacier in Alaska's Tracy Arm triggered the second highest tsuanami ever recorded. The tsunami swept down the fjord, causing more landslides on its way to the ocean. Satellite images show the aftermath, with noticeable run-up areas were trees were swept away. Image Credit: NASA

Alaska’s 2025 Megatsunami Is Emerging as a Climate and Hazard Warning

A landslide triggered by retreat of Alaska’s South Sawyer Glacier generated a 2025 tsunami with a 481-meter maximum runup.
Researchers used satellite images, aerial images, and ground-based data to reconstruct the event in a Science paper.
The case highlights how glacier retreat can contribute to cascading landscape hazards in steep fjords.

Heat-Related Hospitalizations Rose for Decades, With Unequal Burdens Across the U.S.

A study of U.S. adults from 1998 to 2022 found heat-related illness hospitalizations increased over time.
Black adults and low-income communities were disproportionately affected.
The findings underscore heat as both a climate and health-equity issue.

Atlantic climate conveyor could slow far more than expected by 2100, study warns

A new study estimates AMOC could slow by 51% by 2100 under a mid-range emissions scenario.
The finding is more severe than prior average projections cited in the source.
Impacts could include harsher winters in northern Europe, drought in the Sahel and South Asia, and higher sea levels in North America.

There has been a sudden increase in the rate of sea level rise

Satellite Data Suggests Sea Level Rise Shifted Into a Faster Gear Around 2012

Researchers reported a jump in average sea level rise from about 2.9 mm/year before 2012 to 4.1 mm/year afterward.
The shift may reflect several drivers, including faster ice loss, warmer oceans, and changes in water stored on land.
The analysis also raises the possibility that lower aerosol pollution has exposed more underlying warming.

The balcony solar boom is coming to the US

Balcony Solar Is Moving From European Curiosity to U.S. Policy Fight

Utah became the first U.S. state to explicitly allow balcony solar in late 2025.
More than two dozen states are considering similar legislation.
Germany has already seen over a million balcony solar installations.
New certification standards aim to address household and electrical safety concerns.

Study in Science links rumen ciliates to methane output in ruminants

Science lists a new April 2026 paper on rumen ciliates and methane emissions.
The title suggests these microorganisms actively modulate methane output in ruminants.
The result could matter for livestock emissions research and mitigation strategies.

Climate Scientists Shake Their Heads as First US City Running Completely Out of Water

Corpus Christi nears a water cliff as drought and demand push a major Texas hub into emergency planning

Corpus Christi plans to cut water use by 25 percent as soon as September.
The city’s system serves more than 500,000 Texans and major Gulf Coast industry.
The crisis follows a five-year drought and years of warnings about South Texas water stress.
Researchers cited in the source say the situation may preview broader U.S. water challenges.

Cars submerged in flood water with New York City in the background

New flood risk index puts New York at the top of East Coast exposure

A new index found eight East Coast cities at high or very high risk of extreme flood damage.
New York City had the largest absolute number of exposed people and buildings.
The study says 4.4 million people in New York could be exposed to extreme damage.

Great white sharks are overheating

Great White Sharks May Face a Dangerous New Limit in a Warmer Ocean

A new report says mesothermic sharks and tuna could face overheating risks as oceans warm.
These species require unusually high energy and may also face declining food supplies.
Habitat suitable for large warm-bodied fish could shrink, especially during hotter months.
Range shifts in apex predators could alter marine ecosystems more broadly.

Forecasts of a Possible Super El Niño Are Raising the Stakes for Global Weather in 2026

Recent models suggest a very strong El Niño could develop later in 2026.
Some forecasts show a chance that the event could be among the strongest on record.
A super El Niño could intensify heat, drought, flooding, and broader climate disruption worldwide.

Contours of the James Bay Lowlands

James Bay’s Rising Shoreline Shows How Ice Age Forces Still Shape Earth Today

NASA highlighted beach ridges and frozen channels in the James Bay Lowlands from an ISS photograph.
The land around southern Hudson Bay is still rising by about 10 millimeters per year after glacial retreat.
The region is also one of the world’s largest peatland complexes, making it important for carbon storage.

Turns out some skies are bluer than others and the reason is tied up with pollution and climate change.

Why Some Skies Look Bluer Than Others

Blue skies arise from Rayleigh scattering, which favors shorter wavelengths of light.
Larger particles such as aerosols, smoke and moisture produce Mie scattering that can make skies appear white or hazy.
A reported Himalayan dust-storm preprint suggests sky color changes can reflect the mixing of natural dust and pollution.

Researchers found microbial methane from non-producing wells may be vastly underestimated.
The study points to legacy wells as a potentially larger climate problem.
The result could strengthen arguments for more monitoring and faster remediation.
