Nature’s colours can replace toxic pigments

Dye pigments are often toxic, so researchers around the world have long been looking for effective ways to make non-toxic, recyclable and sustainable colours instead. The answer lies in nanotechnology and nature’s own methods.

Long-houl shipping at sea

Ammonia – the key to making long-haul shipping green

Relatively simple adaptation could make the cargo ships of the future completely green. The technology is based on the chemical compound ammonia, some extensive number crunching and one or two engine modifications.

Abandoned cropland helps make Europe cooler

As nations prepare to mitigate climate change, decision makers need to understand how land use fits into the climate equation. A new study looked at land use changes over two decades and found a major shift from cropland to forests.  That change made western Europe cooler.

Your plane travel destroys polar bear habitat

A group of polar bear researchers wants you to do more than worry about the fate of these beautiful animals. They’ve calculated how much summer sea ice is melted per metric tonne of CO2 emissions. Then you can decide if the flight you’re planning to take is worth destroying polar bear habitat.

When art turns climate activist

Can art that literally takes your breath away make you more climate friendly? You can find out yourself if you happen to be in Madrid, at the UN Climate Change Conference, COP 25.

Svalbard reindeer populations rebounding from centuries of hunting

As reindeer go, the animals living on Svalbard might not be Santa’s first choice. They’re a smaller subspecies of their common mainland relatives, and to save energy they basically never run. But because they were nearly exterminated from Svalbard around 1900 — and were then protected in 1925 — the animals provide unique insights into how conservation can help species thrive.

Conflicting consequences of climate change for Arctic geese

Climate change is the big wild card when it comes to the survival of many Arctic species. A new study shows that climate change will be both good and bad for Svalbard barnacle geese populations — although the balance may tip depending upon the severity of future temperature increases and how other species react.

Fewer cows, more trees and bioenergy

Combatting global warming will require major changes in land use, a new climate change report says. One important change could be decreasing the amount of land used to produce livestock — which means that people would have to eat less meat.

$180 million to go toward mapping world’s species

We can’t take care of the Earth’s species unless we know what species exist. A collaborative project that will help us know more is being launched in Trondheim during The Big Challenge science festival.

Reindeer adapt to climate change by eating seaweed

The arctic archipelago of Svalbard is already experiencing dramatic effects from climate change. A new study shows how these changes can force wild reindeer to graze on seaweed, a strategy that increases their likelihood of survival— and is recorded in their poop.

When the extreme becomes the norm: Svalbard reindeer cope with dramatic climate change

Climate change is increasing the likelihood of extreme winter rain events in the Arctic. These kinds of winter storms on Norway’s Svalbard archipelago can cause a thick cap of ice to cover the forage that reindeer eat. You’d think that more frequent rain-on-snow events would spell the end for these arctic animals — but you’d be wrong.

When the hum of insects disappears

Several countries are warning of massive insect deaths. Right now we don’t know how matters stand in Norway. But that’s about to change.

Norwegian trees can power our jets

As much as 20 per cent of jet fuel burned in Norway in 2030 could be biofuel made from the country’s forest residues. This alone could cut greenhouse gas emissions from Norway’s aviation sector by 17 per cent.
