2 August 2017 (NOAA) – Scientists have determined this year’s Gulf of Mexico “dead zone,” an area of low oxygen that can kill fish and marine life, is 8,776 square miles, an area about the size of New Jersey. It is the largest measured since dead zone mapping began there in 1985.The measured size is […]
11 July 2017 (NOAA) – NOAA’s Annual Greenhouse Gas Index, which tracks the warming influence of long-lived greenhouse gases, has increased by 40 percent from 1990 to 2016 — with most of that attributable to rising carbon dioxide levels, according to NOAA climate scientists. [cf. Graph of the Day: NOAA annual greenhouse gas index (AGGI), […]
ATLANTA, Georgia, 3 May 2017 (Georgia Tech) – A new analysis of decades of data on oceans across the globe has revealed that the amount of dissolved oxygen contained in the water – an important measure of ocean health – has been declining for more than 20 years. Researchers at Georgia Institute of Technology looked […]
