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.
Global warming is faster than evolution
If global warming happens too quickly, not all species will be able to adapt in time.
NTNU researcher wins ERC Consolidator Grant
The EU has awarded two million euros for research on how animals are coping with climate changes.
Species more likely to die out with rapid climate change
The great tit and other birds can adapt to changes in their food supply as a result of climate change, but they run into trouble if the changes happen too quickly.
Losing ground in biodiversity hotspots worldwide
Agriculture is eating into areas that are important in protecting some of the most biologically diverse places on the planet. Most of this new agricultural land is being used to grow cattle feed.
Ocean-based negative emissions technology research receives prestigious funding
From 1 July, scientists from 14 institutions in six countries will be examining the opportunities and risks of ocean-based technologies for negative emissions.
Annemie Wyckmans wins the Mission Innovation Champions 2020 award
“This is international recognition of her many years of efforts to promote smart and sustainable cities,” says Henrik Asheim, Norway’s Minister of Research and Higher Education.
New website allows data sharing for upcoming Climate Panel report
NTNU researchers are playing a leading role in a new IPCC report. One way they’re helping is collecting data on a website created and operated by the university.
Global supply chains as a way to curb carbon emissions
The coronavirus outbreak raised everyone’s awareness of the significance of global supply chains to modern economies. But global supply chains also play an important role in greenhouse gas emissions. How they are managed can either increase or decrease carbon emissions, new research shows.
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.
Trees struggle when forests become too small
As forest areas shrink and become fragmented, many tree species face problems. They often rely on animals that can no longer disperse their seeds effectively.
Climate change fuels Australia’s enormous wildfires
Bushfires are a normal part of the cycle of nature in Australia. But not like this. And it is going to get worse.
