Now NASA is flying a set of instruments north of Greenland to observe the impact of the melt season on the Arctic’s oldest and thickest sea ice. Operation IceBridge, NASA’s airborne survey of polar ice, launched a […]

But a new study suggests that this time young pollock had alternative resources that weren’t available during the last warming phase to help buffer ill effects of warming. With 2017 showing signs of cooling, […]
