German scientists discover bacteria that make ice, clouds and rain

Scientists have discovered that a humble species of bacteria may play a major role in producing planetary climates by "seeding" clouds with ice-producing proteins.

Scientists have known for decades that bacterial species such as Pseudomonas

Arctic tundra wildfires return after 10000-year absence

After a 10,000-year absence, wildfires have returned to the Arctic tundra, and a University of Florida study shows that their impact could extend far beyond the areas blackened by flames.In a study published in the July 28 issue of the journal Nature, UF ecologist Miche

Volcanoes could trigger bigger climate impact than thought

Volcanoes could trigger bigger climate impact than thought

Volcanic eruptions might affect Earth’s climate more than thought by releasing far more weather-altering particles than scientists’ suspected, new research finds.To help tease out the influence of volcanoes on global climate, researchers investigated the huge
