In an unusual twist of events, the second most populous country in the world has become an unlikely player in the far flung Arctic high north.

Less ice in Greenland 3,000 years ago than today

A new method for dating ancient sea shells reveals that the Greenland Ice Sheet was smaller between 3,000 and 5,000 years ago than it is today. The new study also indicates that the inland ice is more robust than previously thought.

The best way to remove substances from rainwater

Is rainwater clean? Can it be harmful to aquatic life? And what happens when rainwater from cities is discharged to the aquatic environment?

Wood fuels far less climate friendly than assumed

Burning wood or biofuels taken from slow-growing forests may actually be worse in terms of CO2 emissions than burning fossil fuels, new research suggests.

Warmer in Southern Europe, wetter in the North

European scientists have joined forces in a report to politicians. This is what we can expect of extreme weather in times ahead.

Surviving ash trees help to address evolutionary riddle

A pathogenic fungus is killing thousands of European ash trees every year. Danish researchers are now trying to uncover the genetics behind the unknown defence mechanism in ash trees. Not only to save the ash trees, but also to address an evolutionary mystery in trees.

Only minor effects on fertility from environmental contaminants

Environmental contaminants cause less harm to human reproduction than feared, concludes EU study.

Ocean acidification puts Norway in a pickle

Research since the last IPPC climate change report has provided further proof of mounting acidification of the oceans. Norwegian experts think the fifth IPPC assessment report, to be released in Stockholm this week, should be an eye-opener.

Norway funds four green longshots

Giant batteries for storing renewable energy and solar cells that can use more of the light spectrum are among the winning projects that have been awarded additional funding from the Research Council of Norway.

How algae slime impacts the climate

Algae in the sea ice around the Arctic and the Antarctic convert CO2 into micro-gels. This makes it possible to see whether this cold slime actually counteracts climate change.

Climate change fills polar bears with toxins

The melting ice around Greenland has changed the polar bear’s diet. This means that they are being filled with large quantities of environmental poisons, and that forms a threat to the polar bear’s existence.
