World’s oceans have warmed to a ‘point of no return’
More than half the global ocean sees temperature extremes that 100 years ago were rare.

Bees and butterflies struggle to find flowers in polluted air
Emissions from cars and trucks make it harder for insects to find flowers. That in turn reduces flower visits and pollination, a new study finds.

Widely used pesticides may threaten Earth’s ozone layer
Data show a major class of long-used “eco-friendly” copper chemicals unexpectedly react with soil, making gases harmful to Earth’s protective ozone layer.

Clothes dryers may be a major source of airborne microplastics
Scientists thought washing machines were a leading contributor of microplastics. Now it appears dryers may be an even bigger problem.

The ‘Doomsday’ glacier may soon trigger a dramatic sea-level rise
The ice shelf that had kept it in place could fail within five years. That would speed the glacier’s slip into the ocean, boosting a rise in sea levels.

Recycling a climate-warming gas could make ‘greener’ farmed fish
Instead of warming the climate, methane gas can be collected to help farmers. Along the way, it may also save some fish.
