A comet or asteroid striking the Earth around 13,000 years ago caused the climate to cool, leading to the vanishing of megafauna like mammoths and mastodons in North America, a new study suggests. The research bolsters the argument for indications of such an event, which ushered in a cool period known as the Younger Dryas.
Rising sea levels and reduction of atmospheric ozone are often the first cited pieces of evidence for global warming and the melting of the Arctic shelf, but previous models for projecting decline in Arctic sea ice over the past few decades have been lenient, as Arctic sea ice has declined significantly faster than estimated. A new study from the UW, the University of California Santa Barbara (UCSB), and other federal scientists has shown that 30 to 50 percent of Arctic sea ice decline is due to natural variability in atmospheric weather since 1979.lyst.
It’s the stuff of science fiction, though there’s nothing fiction about it: Researchers have discovered a multitude of previously unidentified microorganisms possess a genetic element that enables them to self-mutate. What’s more, these organisms are so great in number that they dramatically expand the diversity of the tree of life.
As East Africa struggles through a drought, scientists say climate change may be making the situation worse as a warming planet may be altering the weather patterns that bring rain to the region. In Somalia, the rains failed late last year. And the rains before that were meager. Livestock have died. Crops have failed.
Boosting ocean health is exactly what UC Santa Barbara aims to do through a new partnership with the World Economic Forum (WEF), a community of business, political and societal leaders working to improve the state of the world.
