By Jan Minx, Dr. Sabine Fuss and Gregory Nemet Despite the ambitious long-term climate goals of the Paris agreement, there remains a distinct lack of success at ushering in immediate and sustained reductions in global CO2 emissions. This cognitive dissonance has seen the topic of “negative emissions“—also known as “carbon dioxide removal”—move into the limelight […]
By Robert McSweeney Solar geoengineering, or “solar radiation management” (SRM), is perhaps the most controversial of the different ways of limiting human-caused climate change. A commonly voiced objection to the technique is the risk of “termination shock”—the rapid rebounding of global temperatures if SRM is deployed and then suddenly stopped. But a new research article, […]
By Daisy Dunne The arduous journey that king penguins must make in order to hunt fish to bring back to their young could become even longer as the climate warms, research suggests. The study finds that future ocean warming in Antarctica could drive the penguins’ primary hunting grounds further poleward—away from their favored breeding spots. […]
By Daisy Dunne Animals that turn white in the winter to hide themselves in snowy landscapes could struggle to adapt to climate change, research suggests. A new study finds that declining winter snowfall near the Arctic could have varying effects on the survival of eight mammal species that undergo a seasonal color molt from summer […]
By Zeke Hausfather Automated, unmanned drones are poised to revolutionize the package delivery industry, with a number of companies already testing drone-based delivery methods. A new study in Nature Communications looks at the climate impact of a shift from truck-based to drone-based package delivery. It finds that while small drones carrying packages weighing less than […]
By Daisy Dunne Polar bears could be failing to hunt enough seals to meet their energy demands, new research suggests. A study tracking the behavior of nine female bears from 2014 to 2016 over the Beaufort Sea found that some of the animals exerted so much energy during the hunting season that they lost up […]
By Daisy Dunne Just over a year ago, scientists announced the discovery of the world’s largest intact tropical peatland in a remote part of the Congo’s vast swampy basin. The Cuvette Centrale peatlands stretch across an area of central Africa that is larger than the size of England and stores as much as 30 billion […]
By Daisy Dunne Reducing the impacts of human-caused climate change through the use of bioenergy with carbon capture and storage—better known as BECCS—could have major consequences for wildlife, forests and water resources, a new study shows. The large-scale conversion of existing land to BECCS plantations could cause global forest cover to fall by as much […]
By Daisy Dunne The latest assessment report from the Intergovernmental Panel on Climate Change (IPCC) estimates that climate sensitivity has a “likely” range of 1.5 to 4.5°C. The new study, published in Nature, refines this estimate to 2.8°C, with a corresponding range of 2.2 to 3.4°C. If correct, the new estimates could reduce the uncertainty […]
