- The buildup of carbon dioxide in the atmosphere is rising faster than at any time since dinosaurs roamed the Earth. The burning of fossil fuels is largely to blame.
- Scientists have captured the first image of thunder. The map shows the relative strengths of the sound waves emanating from the loud clap.
- A new earthquake struck Nepal on May 12. Its tremors were centered on a new region.
- If people think they have enough time to flee a tornado, they may try to drive away, information shows. This could leave them stuck in traffic — with no protection — when the storm does show up.
- The magnitude 7.8 earthquake that crumbled much of Nepal’s capital city could be overshadowed by larger future earthquakes along the Himalayas, scientists say.
- A single shaft of spewing hot rock created an enormously long chain of mostly undersea mountains in the western Pacific. That chain takes an unexpected eastern curve. The reason, scientists now think, may be a gobbled-up tectonic plate.
- Rapid warming in the Arctic is sapping summer storms of their power to cool. That worsens heat waves across the Northern Hemisphere.
- The supercontinent Pangaea started breaking apart 200 million years ago. This may have been triggered by the shrinking of the Tethys Ocean, a new study finds.
- The lightning associated with some erupting volcanoes can be quite crafty — turning ash into lots of microscopic glass beads.
- Roads and buildings that have mushroomed up around Los Angeles in the past half-century. Now, a study finds they may have created conditions that limit fog. And that could further dry out this very arid part of America’s West Coast.
