The first assessment of toxic heavy metal pollution in the Southern Hemisphere over the last 2,000 years
Human activity, from burning fossil fuels and fireplaces to the contaminated dust produced by mining, alters Earth's atmosphere in countless ways. Records of these impacts over time are preserved in everlasting polar ice that serves as a sort of time.....»»
Aircraft observations point to near neutral carbon dioxide exchange in northern tropical Africa
The forests and grasslands of northern tropical Africa take in about as much carbon dioxide in the wet season as they release in the dry season, according to a new study based on observations from aircraft. The findings contradict earlier research th.....»»
Ancient human DNA hints at why multiple sclerosis affects so many northern Europeans today
Ancient DNA helps explain why northern Europeans have a higher risk of multiple sclerosis than other ancestries: It's a genetic legacy of horseback-riding cattle herders who swept into the region about 5,000 years ago......»»
Uncertainty abounds in seeding the sky to fight climate change, says study
As greenhouse gas levels increase in Earth's atmosphere, scientists are considering ways to temporarily limit rising temperatures. One idea is to inject aerosols into the stratosphere to reflect incoming sunlight, thereby reducing global warming and.....»»
