Dome effect leaves Chinese megacities under thick haze
Airborne black carbon lowers an atmospheric boundary, trapping pollution around major cities and worsening air quality, researchers propose.
- Animals
Climate change now bigger menace than forest loss for snowshoe hares
Shorter snow seasons push climate change ahead of direct habitat loss as menace for Wisconsin snowshoe hares.

Maximum size for Arctic sea ice hits a new low
Warm temperatures helped drop the Arctic sea ice maximum to the smallest size on record.
- Earth
Beware of rockfalls in warm weather
Cracks in cliff faces grow and shrink as temperatures warm and cool, new research shows.
- Climate
Organic molecules help fatten cloud-making water droplets
Cloud-forming water droplets can grow larger thanks to organic molecules on the exterior of the drop, new research suggests.
- Agriculture
Wine quality subject to climate change
Wine quality could suffer as climate change desynchronizes warm temperatures and droughts, preventing grape growers from harvesting at the optimum time.

Climate change threatens quality of French, Swiss wines
Wine quality could suffer as climate change desynchronizes warm temperatures and droughts, preventing grape growers from harvesting at the optimum time.

Antarctic history suggests ice sheet ‘danger’ threshold
Carbon dioxide levels during the Antarctic ice sheet’s formation 34 million years ago suggest that Earth could soon enter “danger zone” for ice sheet’s demise.

Earlier blooming intensifies spring heat waves in Europe
The early arrival of spring plants due to climate change amplifies springtime heat waves in Europe, new climate simulations suggest.

Hurricane frequency dropped during 17th century ‘Little Ice Age’
Atlantic hurricane activity fell around 75 percent when the sun dimmed from 1645 to 1715, a new analysis of shipwrecks and tree rings suggests.
- Oceans
3.5 billion years ago, oceans were cool, not hot
Extensive new evidence from South Africa suggests that 3.5 billion years ago, Earth was locked in a cold spell, with isolated blasts of hydrothermal heat that may have helped incubate life.
- Environment
California gas leak spewed massive amounts of methane
New estimates suggest that a 2015 natural gas well blowout injected tons of greenhouse gases into the Los Angeles atmosphere.
