Dire outlook despite global warming 'pause': study
A global warming "pause" over the past decade may invalidate the harshest climate change predictions for the next 50 to 100 years, a study said Sunday—though levels remain in the danger zone.
The mammoth's lament: Study shows how cosmic impact sparked devastating climate change
(Phys.org) —Herds of wooly mammoths once shook the earth beneath their feet, sending humans scurrying across the landscape of prehistoric Ohio. But then something much larger shook the Earth itself, and ...
Physicists develop revolutionary low-power polariton laser
(Phys.org) —Lasers are an unseen backbone of modern society. They're integral to technologies ranging from high-speed Internet services to Blu-ray players.
Comprehensive analysis of impact spherules supports theory of cosmic impact 12,800 years ago
About 12,800 years ago when the Earth was warming and emerging from the last ice age, a dramatic and anomalous event occurred that abruptly reversed climatic conditions back to near-glacial state. According ...
