Choking back tears, Yeb Sano speaks of the devastation in the Philippines
His eyes filling with tears and his voice choking with emotion over the disaster inflicted on his country, the delegate from the Philippines pleaded at U.N. climate talks Monday for his colleagues from around the world to agree on ways to reduce the greenhouse gas emissions that scientists blame for global warming.
Declaring that "human influence on the climate system is clear," a U.N.-assembled panel of scientists reported Friday that "it is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century."
Scientists and government representatives are meeting in Stockholm this week to produce the latest high-level review of climate change. It's thousands of pages of material, and if it's done right, it should harbor very few surprises.
That's because it's supposed to compile what scientists know — and what they don't — about climate change. And that's left some scientists to wonder whether these intensive reviews are still the best way to go.
The effects of climate change often happen on a large scale, like drought or a rise in sea level. In the hills outside Missoula, Mont., wildlife biologists are looking at a change to something very small: the snowshoe hare.
Life as snowshoe hare is pretty stressful. For one, almost everything in the forest wants to eat you.
Alex Kumar, a graduate student at the University of Montana, lists the animals that are hungry for hares.
"Lynx, foxes, coyotes, raptors, birds of prey. Interestingly enough, young hares, their main predator is actually red squirrels."
