Drones and satellite imaging to make forest protection pay

Every year 7 million hectares of forest are cut down, chipping away at the 485 gigatonnes of carbon dioxide (CO2) stored in trees around the world, but low-cost drones and new satellite imaging could soon protect these carbon stocks and help developing countries get paid for protecting their trees.

Arctic permafrost might contain ‘sleeping giant’ of world’s carbon emissions

As temperatures rise in the Arctic, permafrost, or frozen ground, is thawing. As it does, greenhouse gases trapped within it are being released into the atmosphere in the form of carbon dioxide and methane, leading to previously underestimated problems with ocean acidification and potential mercury poisoning.

Governments at COP24 should focus on building a global electricity grid – Prof. Damien Ernst

Governments at the COP24 climate change conference in Katowice, Poland, which ends on 14 December, should tackle fossil-fuel reliance by building a global energy grid that connects renewable energy from all around the world - and the best place to start is with a giant wind farm in Greenland, says Professor Damien Ernst, an energy scientist from the University of Liège, Belgium.

Why we may be able to save the Greenland ice sheet

Studies of ice melt in the Arctic suggest that the world may have a fighting chance of preventing huge sea level changes that would result from the dramatic collapse of the vast ice sheets that cover Greenland, but that more work is needed to understand the wider effects.

The Arctic faces substantial changes even if we meet climate targets – Marianne Kroglund

Melting sea ice, plastic waste, biodiversity loss – the Arctic is facing unprecedented environmental pressure and will continue to change until 2050 even if we meet targets to limit global warming, according to Marianne Kroglund from the Arctic Council, an intergovernmental forum addressing the challenges faced by Arctic governments and indigenous peoples.

‘Internet of electricity’ and zero-carbon molecules will help decarbonise Europe – report

An ‘internet of electricity’, zero-carbon cities and turning European soils into carbon sinks are among a slew of ambitious ideas to decarbonise our society and slash greenhouse gas emissions proposed by environmental experts in a report published on 28 November.

Storing CO2 underground can curb carbon emissions, but is it safe?

At first glance, it almost sounds crazy. Can we really take carbon dioxide emissions from an industrial plant and store them underground? To find out, research is currently taking place to test if such an idea is not only viable but safe, and prove that to the public.

Europe’s eyes in the sky are helping to solve energy, land-use problems in Africa

Scientists have created a solar atlas of Egypt, revealing where the sun’s rays shine most brilliantly and where dust storms obstruct its light. And in Niger, forecasters are guiding pastoralists towards grazing areas and water sources – and away from conflict with sedentary farmers.

Waste CO2 to be turned into ingredients for fuel, plastics and even food

Scientists are ramping up efforts to turn waste CO2 from industry into chemicals such as methanol in a bid to reduce emissions and provide a new source of raw materials for use in fuel, cement and food production.

System to rid space station of astronaut exhalations inspires Earth-based CO2 removal

When astronauts aboard the International Space Station (ISS) exhale carbon dioxide (CO2), it’s removed from the air and pumped into space. Could an Earth-based version help remove greenhouse gas emissions from our atmosphere?
