"The growing impacts of climate change have already pushed more than 18 million people to migrate within South Asian countries, but that could more than triple in three decades if global warming continues on its current path, researchers warned on Friday."

"New research shows that more than 90 per cent of sunflower sea stars off the West Coast have died over the past decade, and the species is close to extinction."

"As droughts become longer, the soil additive could save on irrigation water and, if mass produced, might compete with energy sources such as oil and gas."

"Biochar, a charcoal-like substance made from burning organic materials in a low or zero-oxygen environment, can improve the quality of soil and trap carbon dioxide in the earth for potentially hundreds, or even thousands, of years.

But a recent study suggests that it may also have another benefit: it could reduce irrigation costs for farmers, thanks to its highly porous and water-absorbent properties.
