Well-meaning climate measures can make matters worse

Lifestyle changes can reduce our greenhouse gas emissions and help protect nature. While some actions offer great potential, some aren’t as effective as we think and may even require more land and water, such as shifting to renewable energy.

Gas instead of coal is 50% better for the climate

We can do a lot to save the climate by switching from coal to natural gas. And we can shelve concerns about the negative climate impact of methane emissions from gas production, say researchers.

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.

Carbon capture is cheaper than ever

According to a new report, many years of research effort have resulted in significant reductions in the cost of full-scale carbon capture and storage.

When the Chinese giant awakes

When China sets its sights on a goal, the country can change at a blindingly rapid pace. Now the country is focused on innovation and technological innovations, with renewable energy at the forefront.

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.

Making it easier to capture CO2 in the cement industry

Cement manufacture accounts for as much as seven per cent of global greenhouse gas emissions. A new hybrid technology makes it easier and less expensive to capture and purify CO2 produced by the industry. And the technology can be retrofitted to existing plants.

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.

Spending our carbon budgets wisely

Our carbon emissions are much higher than are needed for us to have happy, healthy lives. But cutting these emissions requires us to think differently about how we measure growth and progress.

Geoengineering, other technologies won’t solve climate woes

The countries of the world still need to cut their carbon dioxide emissions to reach the Paris Agreement’s climate targets. Relying on tree planting and alternative technological solutions such as geoengineering will not make enough of a difference.

Clothing, furniture play a role in ocean and freshwater pollution

Lakes choked with algae and marine “dead zones” result from too many nutrients in the water. The traditional culprit is agriculture, which relies on fertilizer to boost plant growth. But the production of consumer goods, like clothing, is also a major — and growing — contributor.

New filter removes run-off chemicals

The filter will first be used to recover aircraft de-icing chemicals. In the future it will also be used in urban areas to remove environmental toxins, pollution and probably microplastics.

Envisioning a future where all the trees in Europe disappear

Global climate change is already affecting the globe, as demonstrated by the shrinking polar ice cap, melting glaciers and cities in the grips of longer, more intense heat waves. Now a team of researchers has conducted a radical thought experiment on how extreme land use changes could influence future climate.

New study estimates the carbon footprints of 13,000 cities

Many see cities as the new front lines of the climate change fight. Identifying the mayors and city councils in cities with the biggest carbon footprints, and the most power to make big changes, could mobilize a wave of reinforcements.

Capturing CO2 using heat pumps

Capturing the greenhouse gas CO2 from industrial processes such as cement manufacture is a demanding and therefore expensive exercise. However, by introducing a renewable powered heat pump in the capture system, the energy required to capture CO2 is reduced by three quarters.
