In Greenland’s Melting Ice, A Warning on Hard Climate Choices…

Greenland is melting at an unprecedented rate, causing vast quantities of ice to disappear and global sea levels to rise. The fate of the ice sheet is not sealed, but unless CO2 emissions are sharply cut, the long-term existence of Greenland’s ice is in doubt… Read the article here at Yale Environment 360: https://e360.yale.edu/features/in-greenlands-melting-ice-a-warning-on-hard-climate-choices Advertisements

What Earth’s gravity reveals about climate change…

Summary: On March 17, 2002, the satellite duo GRACE was launched to map the Earth’s gravity field more precisely than ever before. The measurements make it possible to monitor the terrestrial water cycle, the mass balance of ice sheets and glaciers or changes in sea levels. This helps to better understand important trends in the […]

Melting glaciers causing sea levels to rise at ever greater rates…

Summary: Melting ice sheets in Greenland and the Antarctic as well as ice melt from glaciers all over the world are causing sea levels to rise. Glaciers alone lost more than 9,000 billion tons of ice since 1961, raising water levels by 27 millimeters, an international research team has now found… Read about it here […]

As High-Tide Flooding Worsens, More Pollution Is Washing to the Sea…

As sea levels rise, high-tide flooding is becoming a growing problem in many parts of the globe, including cities on the U.S. East Coast. Now, new research shows that as these waters recede, they carry toxic pollutants and excess nutrients into rivers, bays, and oceans… Read this article at Yale Environment 360: https://e360.yale.edu/features/as-high-tide-flooding-worsens-more-pollution-is-washing-to-the-sea

Abrupt Sea Level Rise Looms As Increasingly Realistic Threat by Nicola Jones: Yale Environment 360…

Ninety-nine percent of the planet’s freshwater ice is locked up in the Antarctic and Greenland ice caps. Now, a growing number of studies are raising the possibility that as those ice sheets melt, sea levels could rise by six feet this century, and far higher in the next, flooding many of the world’s populated coastal […]
