Tucson Sentinel: As temperatures around the world rise, a recent study has shown hundreds of species would need to evolve about 10,000 times faster than they have in the past to adapt to the rapid climate change expected in the next 100 years.
The study, which was led by University of Arizona ecologist John J. Wiens, analyzed the way species adapted to climate change in the past, using data from 540 living species from all major groups of terrestrial vertebrates, including amphibians, reptiles, birds and mammals,...

A scientific storm is brewing over the hurricane-climate connection

Grist: It`s the month of July, right before the Atlantic hurricane season really gets chugging. And there are already signs that a busy year might be on the way, chief among them the unusual early appearance of a "Cape Verde-type" storm. These storms are typically sparked by atmospheric waves traveling all the way from the coast of Africa, and generally don`t appear until later in the hurricane season.
And suddenly, an MIT scientist - who`s arguably the world`s top expert on hurricanes - publishes a...
