Improving the 'cold chain' could help reduce global hunger and lessen the effects of climate change

A third of the world’s food spoils in transit and never reaches the table — food that could feed more than the 870 million people on Earth who don't get enough to eat. Improved refrigeration and transportation of perishable foods through a better integrated “cold chain” could combat world hunger and mitigate climate change without the need to grow more food to feed an increasing population.

Two new studies suggest more melting is in store for the Greenland ice sheet

When it comes to global warming, it appears that the greatest rate of warming is happening at the poles. That conclusion was strengthened recently by a couple of new studies focusing on the melting of the Greenland ice sheet. They each looked at different measurements, but both agreed that the impacts of global warming on the ice are underestimated.

Melting Arctic sea ice doubles the chances of harsh winters in other parts of the world

When most people hear the term "global warming," they naturally think of air temperature. In reality, more than 90 percent of the warming caused by greenhouse gases happens in the oceans. Much of this warming takes place in the waters in and around the Arctic Ocean, leading to increasingly rapid melting of sea ice. A new study links this melting to cold, harsh winters that are becoming more common in parts of the world.
