Alaska’s Columbia glacier began rapidly retreating around 1980, and its leading edge has moved more than 20 kilometers inland. These images, captured by the joint NASA / U.S. Geological Survey Landsat satellites, were stitched together into a video to show the glacier’s dynamic evolution from 1972 to 2019.

Greenland losing ice seven times faster than in the 1990s – Sea level rise from Greenland melt tracking highest climate projections

10 December 2019 (Utrecht University) – Greenland is losing ice seven times faster than in the 1990s and is tracking the IPCC’s high-end climate warming scenario, which would see 40 million more people exposed to coastal flooding by 2100. The findings, published in Nature today, show that Greenland has lost 3.8 trillion tonnes of ice […]

Global pattern in the cumulative development of coastal hypoxia in the periods before 1969, 1970-1989, and 1990-2015. Each red dot represents a documented case related to human activities. Green dots are sites that have improved. Since the 1960s, the global number of hypoxic systems has about doubled every ten years up to 2000. Data: Based on Diaz and Rosenberg (2008), Diaz, et al. (2010), and Conley et al. (2011). Graphic: Laffoley and Baxter, 2019 / IUCN

Oceans losing oxygen at unprecedented rate, experts warn

Norway greenlights copper mine that will dump two million tons of tailings in Arctic fjord each year – “Dumping of mining waste will kill every living thing on the ocean floor in the immediate area and disturb spawning grounds over a much greater distance”
