What counting Florida butterflies can tell the world about climate change

Every year when summer temperatures sizzle and the rest of South Florida heads inside, a dedicated crew of citizen scientists ventures into the buggy heat to do an increasingly difficult job: count butterflies.

Ice cave in Transylvania yields window into region’s past

Ice cores drilled from a glacier in a cave in Transylvania offer new evidence of how Europe's winter weather and climate patterns fluctuated during the last 10,000 years, known as the Holocene period. The cores provide insights into how the region's climate has changed over time. The researchers' results, published this week in the journal…

Mammals Shrank During Ancient Global Warming Event

Between 56 million and 53 million years ago, Earth experienced a series of extreme global warming events that radically altered life on the planet. During the first event, the Paleocene-Eocene Thermal Maximum (PETM), carbon levels spiked and temperatures increased as much as 8 degrees Celsius (14.4 degrees Fahrenheit). A second event, known as the Eocene…
