Oceans
Are major ocean currents moving to turn Earth into a snowball?
A key ocean current that warms Europe is weakening, which could lead to a big chill. Scientists are now discussing how we might avoid that.

Antarctica faces a green and weedy future
Warming is allowing alien species to invade a land that had been isolated for 30 million years. They now threaten local ecosystems unique to Antarctica.

Global coral die-offs signal Earth’s first climate tipping point
The corals offer a dire warning, scientists say, and suggests that more such catastrophic points of no return could occur soon — some within a decade.

During heat waves, trees spew chemicals that worsen air pollution
New data point to how heat waves and other climate change will make it harder to curb ozone and other types of toxic air pollution — even outside of cities.
