A long, controversial investigation of a polar bear scientist has ended with his government employer saying it does not look like he engaged in any scientific misconduct.
Charles Monnett is a wildlife researcher with the Bureau of Ocean Energy Management, part of the Department of the Interior.

But two new groups aim to work from within, using conservative arguments to win over skeptics.
Arctic sea ice is in sharp decline this year: Last week, scientists announced that it hit the lowest point ever measured, shattering the previous record.
But it turns out that's not the most dramatic change in the Arctic. A study by Canadian researchers finds that springtime snow is melting away even faster than Arctic ice. That also has profound implications for the Earth's climate.
This year’s stubborn drought and the changing climate will have serious consequences for Colorado’s multi-billion dollar recreation and farming industries, as well as the state’s forests that have seen severe, un-naturally large wildfires recently.
