Slashing greenhouse gas emissions would probably not yield visible results until mid-century, researchers have said, cautioning that humanity must manage its expectations in the fight against global warming. Even under optimistic scenarios in which carbon pollution falls sharply, climate change will continue for decades, they reported Tuesday in the journal Nature Communications. “We need to

Global warming is turning clear mountain lakes green in the western United States because of an increase in algae blooms “without historical precedent”, researchers reported on Tuesday. The concentration of algae in two remote mountain lakes more than doubled in the past 70 years, researchers at Colorado State University found. Their results, published in the

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
