Parts of the Arctic Ocean containing at least 15 percent sea ice have increased by 78 percent when compared with the extent last year at this time, according to data compiled by the National Snow and Ice Data Center.
More accurate, more frequent measurements of mountain snowpacks will allow water managers to mete out reservoirs with greater confidence. Two watersheds in the western US are testing grounds for a new aerial approach.
Antarctic ice core samples, up to 150,000 years old, may help scientists estimate whether it will take 50 years - or 500 years - for the Ross Ice Shelf to collapse at the current rate of climate change.
Polar bears' territorial tendencies and the diminishing ice season on Hudson Bay are conspiring to leave the animals less time to eat, researchers say. This bodes ill for their ability to reproduce, and survive.
Melting Arctic ice will create new sea routes, a new study says, including the potential for light ice-breakers to reach the North Pole. New Arctic shipping routes would still be seasonal rather than year-around.
Today is election day in the US, but climate change should have been on the campaign agenda months ago. It shouldn't take a disaster like superstorm Sandy to finally bring it back into the conversation.
