Tree tops sparkle with electricity during thunderstorms
Ultraviolet cameras captured faint electrical flashes from leaves and branches as storm charges built up in the atmosphere.

Lakes are growing in Alaska. That’s not entirely a bad thing
Alaska’s glacial lakes are growing as glaciers retreat out of basins. These lakes will change desolate glacial rivers into thriving salmon habitat.

Hundreds of studies have missed how much the oceans are rising
A widely used method to calculate sea level rise may have missed up to a century of change, so the risks could hit home for millions sooner than thought.

Take it from the Olympics, slushy winter sports may be the new normal
Ice arenas and artificial snow now dominate the winter Olympics. Athletes there — and everywhere — may need to adjust how they train and perform.

Climate change could threaten monarch mass migration
Suitable milkweed habitat in Mexico may shift south, fracturing existing migration routes and possibly pushing some butterflies to stay put.

Metal pollution from a rocket reentry detected for the first time
Direct detection of lithium from a SpaceX rocket reentry offers new evidence that metal pollution from space debris could threaten the ozone layer.

Halting irreversible changes to Antarctica depends on choices made today
Antarctic Peninsula projections show accelerating ice loss, warming oceans and global sea level impacts tied to greenhouse gas emissions.

Snowball Earth might have had a dynamic climate and open seas
Sediments from Scotland hint that ocean-atmosphere interactions continued more than 600 million years ago despite widespread ice.
