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.
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.
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.
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.
Disposable products are bad. But durable goods account for two-thirds of the global household’s energy footprint.
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.
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.
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.
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.
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.
The EU has awarded two million euros for research on how animals are coping with climate changes.
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.
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.
From 1 July, scientists from 14 institutions in six countries will be examining the opportunities and risks of ocean-based technologies for negative emissions.
“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.
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.
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.
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.
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.
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.
Bushfires are a normal part of the cycle of nature in Australia. But not like this. And it is going to get worse.
Several high-profile studies report that ocean acidification will affect coral reef fish behaviour enough to jeopardize their survival. One research team looked more deeply at this assertion — and found it is simply not true.
