Climate change
The push to end harmful cooking methods worldwide
A third of the world’s population cooks with fuels that produce harmful fumes when burned. Breathing in the fine particles produced by cooking with wood, charcoal, coal, animal dung and agricultural waste can penetrate the lungs and cause multiple respiratory and cardiovascular problems, including cancer and strokes. Women and children are most at risk. Fifty countries gathered in Paris on Tuesday to raise funds to replace dangerous cooking with clean ones. Marco Werman speaks with Dymphna van der Lans, CEO of the Clean Cooking Alliance.
Climate change is rapidly shifting Costa Rica’s sensitive ecosystems
The tiny Central American country of Costa Rica is known as a green paradise. But climate change is hitting the country in a multitude of ways, including increasing its risk from storms and natural disasters. Nowhere is the shifting planet being felt more than in some of the country’s most iconic parks and reserves, where ecosystems are changing rapidly.
‘Blue Blob’ slows glacial melt in Iceland as temperatures rise across the globe
About 10% of Iceland is still covered by glaciers — what Icelanders call their “white diamonds.” Now, a mysterious patch of cold water in the North Atlantic Ocean, known as the “Blue Blob,” is helping slow down the rate at which these glaciers are melting. But scientists are concerned about how long this will last.
Animal species are evolving to adjust to climate change, but scientists say time is running out
Scientists have been studying changes in animal physiology and behavior, some of which they believe are linked to rising global temperatures. They say the adaptations are beneficial, but may have limitations in the long term.
This greenhouse innovation helps farmers in India cope with climate change
The “greenhouse-in-a-box” is part of a solution designed to help smallholder farmers cope with the vagaries of a changing climate. The design, essentially a low-cost, scaled-down version of a standard greenhouse, is the brainchild of an Indian startup called Kheyti.
