Studies investigating whale-watching boats and the inner ears of marine mammals could soon provide new insight into the effects of noisier oceans on cetaceans – dolphins, whales and porpoises – who depend on their hearing for navigating, finding food and communicating underwater.
From high winds and heavy rainfall to droughts and plummeting temperatures, people in Europe have already begun to feel the effects of extreme weather. As we get used to this new reality, scientists are investigating how it will affect how we get around and whether our infrastructure can cope.
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.
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 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.
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.
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.
Dedicated policies and guidelines aim to reduce everyday exposure.
Mental health and free wifi in fast food joints have been raised as pertinent issues, says public health expert.
Notre Dame restoration is a learning opportunity, says historian.
