Exhaust gas emissions have doubled the amount of ground-level ozone. Vegetation is being destroyed. Food production is decreasing. Researchers now fear that the damage is greatest in the Arctic regions.
New: Land-based glaciers outside of the main ice sheets in Antarctica and Greenland have lost more than 9,000 billion tons of ice since 1961, raising sea levels by 27 millimeters.
A new method is developed by researchers at UiO to combine heaps of satellite images to create a complete time series of glacier movement. Study recently published in The Cryosphere.
