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 […]

Report by Brian Kahn on the Greenland melt season on climatecentral.org “Warm, wet conditions rapidly kicked off the melt season this weekend, more than a month-and-a-half ahead of schedule. It has easily set a record for earliest melt season onset, and marks the first time it’s begun in April…” Read the rest of his report here: […]
Summary: In 1884, a delegation of international representatives convened in Washington, D.C. to recommend that Earth’s prime meridian (the north-south line marking zero degrees longitude) should pass through the Airy Transit Circle at the Royal Observatory in Greenwich, England. Why the Greenwich prime meridian shifted a few hundred feet… See image below: The Airy meridian […]

from wri.org… Many coastal communities rely on mangroves for food, forest products and tourism revenue, and the forests provide a natural coastline defense to storm surges by reducing wave and wind velocity. New analysis relies on satellite data to survey the state of these important ecosystems… Read the article here: Satellite Data Reveals State of […]
According to “science.nasa.gov”: In the early 1990s, one thing was fairly certain about the expansion of the Universe. It might have enough energy density to stop its expansion and recollapse, it might have so little energy density that it would never stop expanding, but gravity was certain to slow the expansion as time went on… […]
Tectonic Plate Movement and its Consequences The Earth lithosphere is broken up into tectonic plates. Twenty plates are continuously migrating. The great majority of all earthquakes and volcanic activity occurs along the plate boundaries. The movement of the plates varies from zero to 100 mm annually. – See more at: Storytelling Side Accordion – A […]

Yale Environment 360: Global Maps Detail Seasonal and Geographic Trends in Ocean Acidification.
Scientists have uncovered a cache of satellite images of Earth from the 1960s that had been forgotten in storage for nearly 50 years and that push back the first satellite images of our planet a full 17 years. ‘Lost’ Satellite Photos Reveal Surprising Views of Earth in the 1960s.
