Our arctic heritage is threatened by climate change
The cultural heritage of Svalbard is unique. It reflects human life and activity in a harsh and fragile environment. Researchers are now working to preserve it for posterity.

What plants need to withstand drought
When temperatures rise, it affects the plants that agriculture and we depend on. Now we know more about how plants resist drought.
Demand for rare minerals and metals creates eco-dilemma
The world is crying out for rare minerals for the manufacture of electric cars, wind turbines and other technologies that we simply need more of. But how can we guarantee access to these resources without threatening the natural world and mankind as we know it?
ERC grant on CO2 uptake by the oceans
NTNU Associate Professor Jason Hearst has been awarded an ERC Starting Grant from the European Research Council (ERC). He will investigate how turbulence affects the ocean’s ability to absorb CO2.
Is green growth possible?
Increases in economic growth contribute to one-for-one increases in carbon emissions. Energy system decarbonization and economic productivity gains are the most effective carbon emissions mitigation mechanisms for sustainable economic development.
Finding order in chaos wins the prize
The Nobel Prize in Physics is going to three individuals who found that the world isn’t always as chaotic as we think.
Another climate summit that changes almost nothing – again?
World leaders have gathered in Glasgow to discuss climate change. But the most likely outcome is that actions won’t extend beyond the talk.
New ultra-high material efficient, low-cost solar cells — using nanowires
A new method using nanowires can make solar panels much more efficient and much cheaper than today.
Map shows carbon dioxide emissions for more than 100,000 European cities
Cutting greenhouse gas emissions to meet climate goals won’t be easy, to put it mildly. But the job just got a little simpler for 34 European countries with the creation of a new interactive map that pinpoints emissions at a local level.
Glasgow climate talks and the fate of the planet
Just over two months after UN Secretary-General António Guterres described a new climate report on the state of the planet as “code red for humanity”, the nations of the world have the chance to do something about it. But will they?
A quick end to oil won’t save the climate
An abrupt halt to oil activities in the North Sea is not the solution to the climate crisis. The way forward is to establish alternatives to oil.
Moose appetite for deciduous trees counteracts warming effects
With the warming climate, forests are growing faster than before, and deciduous species are growing the fastest. Recent research illustrates just how much moose foraging limits this growth.
Is it too late to save the planet?
Code red for humanity, says the IPCC. Fortunately, there’s still a lot we can do, but we have no time to lose, says NTNU climate researcher Edgar Hertwich.
Provoking climate engagement
As you walk around the city, nature “pops up” in unexpected places. Like a “lung tree” – a tree that breathes. The Nature in Your Face research project wants to use art to create engagement.
Blocking the sun to control global warming
It sounds like something out of a bad science fiction movie — artificially blocking sunlight to keep global warming from overheating the Earth. Nevertheless, a small cadre of researchers is studying the option — so that if humankind ever needs to use it, it will be an informed decision.
Rapid action can help prevent the worst consequences of global warming
A new report from the Intergovernmental Panel on Climate Change (IPCC) describes with unnerving detail just what can happen if nations fail to limit greenhouse gas emissions. But rapid international action will keep the worst consequences at bay, the panel said.
A robotic microplankton sniffer dog
The microscopic, free-floating algae called phytoplankton — and the tiny zooplankton that eat them — are notoriously difficult to count. Researchers need to know how a warming climate will affect them both. A new kind of smart, lightweight autonomous underwater vehicle (LAUV) can help.
CO2 heat pumps smart option for hotels in cold climates
Researchers have studied the energy consumption of 140 hotels in Norway and Sweden. The use of CO2 heat pumps could cut energy consumption in these hotels by about 60 per cent.
Are durable goods really that good?
Disposable products are bad. But durable goods account for two-thirds of the global household’s energy footprint.
Green quay will provide a green fjord
Big things might be happening soon with cruise traffic in the Geiranger fjord. Smaller vessels and adapted green quay facilities could make for a green fjord and offer a solution for preserving the World Heritage site.
Shedding light — on the polar night
The polar night is dark — if you’re a person. But not if you’re a krill or a seabird or a fish. In the first episode of NTNU’s new English-language podcast, 63 Degrees North, learn how researchers discovered that there’s more than enough light in the polar night for the tiny creatures who live there.
Abandoned cropland should produce biofuels
More biofuels are needed to counteract climate change. But producing them shouldn’t diminish food production or wilderness areas. The solution may be to grow more grass on recently abandoned cropland.
Smart site selection can make hydropower greener
Even though new hydropower dam developments are intended to provide green energy, they can drown areas that are rich in plant and animal species. But this kind of collateral damage can be limited by strategic site selection, a new study shows.
Skinnier but resilient geese thriving in the high Arctic
Barnacle geese in the Arctic have been on a diet. So many now migrate to northern breeding grounds that in some places there’s less food to go around. The good news is that it doesn’t seem to restrict their population growth — yet.
