The deadly July floods in Belgium and Germany bear the fingerprints of human-caused climate change, scientists say.

Haiti’s citizen seismologists helped track its devastating quake in real time
Two scientists explain how citizen scientists and their work could help provide a better understanding of Haiti’s seismic hazards.

The new UN climate change report shows there’s no time for denial or delay
Human-caused climate change is unequivocally behind extreme weather events from heat waves to floods to droughts, a massive new assessment concludes.
- Space
A lunar magnetic field may have lasted for only a short time
New analyses of Apollo-era lunar rocks suggest that any magnetosphere that the moon ever had endured for no more than 500 million years.

A stunning visualization of Alaska’s Yukon Delta shows a land in transition
Water and ice helped form the Yukon River’s delta. Now, climate change is reshaping it.
- Paleontology
Pterosaurs may have been able to fly as soon as they hatched
A fossil analysis shows the flying reptile hatchlings had a stronger bone crucial for lift-off that adults and shorter, broader wings for agility.
- Paleontology
Insects had flashy, noise-making wings as early as 310 million years ago

Why planting tons of trees isn’t enough to solve climate change
Massive projects need much more planning and follow-through to succeed – and other tree protections need to happen too.
