A Slow-burn Existential Threat

July 23, 2019 / activist360 / Leave a comment

There are islands in the Chesapeake Bay that have already succumbed to sea level rise, one of them is Holland Island.

Even in a best case scenario, the consensus is that we’ll get at least two feet of sea level rise by the year 2100.

One big question is: What will happen when flooding gets worse and worse and people decide there’s no hope for them anymore to live in their respective towns.

Greenland’s Jakobshavn Glacier Reacts to Changing Ocean Temperatures

April 10, 2019 / activist360 / Leave a comment

NASA’s Oceans Melting Greenland (OMG) mission uses ships and planes to measure how ocean temperatures affect Greenland’s vast icy expanses. Jakobshavn Glacier, known in Greenlandic as Sermeq Kujalle, on Greenland’s central western side, has been one of the island’s largest contributor’s to sea level rise, losing mass at an accelerating rate.

In a new study, the OMG team found that between 2016 and 2017, Jakobshavn Glacier grew slightly and the rate of mass loss slowed down. They traced the causes of this thickening to a temporary cooling of ocean temperatures in the region.

This visualization shows total sea level change between 1992 and 2014, based on data collected from the TOPEX/Poseidon, Jason-1 and Jason-2 satellites. Blue regions are where sea level has gone down, and orange/red regions are where sea level has gone up. Since 1992, seas around the world have risen an average of nearly 3 inches.
