Affordable insurance against droughts and other climate risks will help to improve food security and protect smallholder farmers.
The movement of Arctic sea ice is expected to significantly increase this century, raising the risk of more widely transporting pollutants like microplastics and oil.
While there is a growing body of research showing how the loss of Arctic sea ice affects other parts of the planet, this study is the first to also consider the long-range effect of Antarctic melt.
A new Columbia study finds that nitrogen emissions from agricultural production in the tropics is likely to increase and, in some cases, overtake temperate climates, exposing more people to polluted air and water.
