Dormant “zombie fires” scattered across the Arctic region – remnants of record blazes last year – may be coming to life after an unusually warm and dry spring, scientists warned Wednesday. “We have seen satellite observations of active fires that hint that ‘zombie’ fires might have reignited,” said Mark Parrington, a senior scientist and wildfire expert at

At its heart, climate change denial is a conflict between facts and values. People deny the climate crisis because, to them, it just feels wrong. As I’ve argued elsewhere, acknowledging climate change involves accepting certain facts. But being concerned about climate change involves connecting these facts to values. It involves building bridges between the science

Our diets can have a big environmental impact. The greenhouse gas emissions involved in producing and transporting various foods has been well researched, but have you ever thought about the water-scarcity impacts of producing your favourite foods? The answers may surprise you. In research recently published in the journal Nutrients, we looked at the water

Global warming has put a glacier in the Italian Alps at risk of collapse, officials warned, leading to road closures, travel restrictions, and evacuations in the immediate vicinity. Municipal officials issued the order after surveyors observed a significant increase in the sliding speed of the Planpincieux glacier, which rests on the Italian side of the

Climate change is already having staggering effects on oceans and ice-filled regions that encompass 80 percent of the Earth, and future damage from rising seas and melting glaciers is now all but certain, according to a sobering new report from the United Nations. The warming climate is killing coral reefs, supercharging monster storms, and fueling

As it looks increasingly unlikely we’re going to meet our climate mitigation targets, scientists have been investigating more and more extreme solutions, such as geoengineering. Examples include spraying huge amounts of sunlight-reflecting particles into the atmosphere, or dumping trillions of tons of fake snow onto glaciers to stabilise them. These ideas are untested, incredibly risky,

Pacific islanders are running out of time. If global emissions are not drastically reduced, thousands of low-lying atolls may become uninhabitable within decades. And the biggest threat doesn’t actually come from losing land to rising seas. Small island states in the Pacific are responsible for only 0.03 percent of the world’s carbon dioxide emissions, and

Hopes of a breakthrough in international climate change ambitions are being downplayed for a landmark meeting in New York. The United Nations climate action summit looks set to disappoint the thousands of campaigners who will take to the city’s streets just days earlier. The summit is arguably the most important moment for climate change since

On its surface, the plan was simple: gene-hack mosquitoes so their offspring immediately die, mix them with disease-spreading bugs in the wild, and watch the population drop off. Unfortunately, that didn’t quite pan out. The genetically-altered mosquitoes did mix with the wild population, and for a brief period the number of mosquitoes in Jacobino, Brazil
