A new NASA field campaign will begin flights over the Arctic this summer to study the effect of sea ice retreat on Arctic climate. The Arctic Radiation IceBridge Sea and Ice Experiment (ARISE) will conduct research flights Aug. 28 through Oct. 1, covering the peak of summer sea ice melt.
An outlook report by the Great Barrier Reef Marine Park Authority (GBRMPA), the government agency tasked with overseeing the reef’s health, declines to mince its words. The reef is an “icon under pressure” that has suffered a dip in health since the last major analysis of its condition in 2009.
Climate change, which is causing the oceans to warm, is cited as the leading threat to the reef, followed by pollution running off the land into the sea, coastal development and direct impacts such as fishing.
