Coral Reef Death Impacting Sea Levels

In the Florida Keys, the U.S. Virgin Islands and Maui, coral reef degradation has caused sea floor depths to increase as sand and other sea floor materials have eroded over the past few decades, the USGS study found. In the waters around Maui, the sea floor losses amounted to 81 million cubic meters of sand, rock and other material – about what it would take to fill up the Empire State Building 81 times, the researchers calculated.

New Study On Arctic Ice Melt

Arctic sea ice has been rapidly declining since satellites first started tracking it in 1979, and according to NASA, roughly 13.3 percent of the ice disappears every decade. Models have projected that manmade global warming would heat the Arctic faster than it would heat more temperate regions, and observation has borne that out. The Arctic is warming at least twice as fast as the rest of the globe, and the first two months of this year both had the lowest levels of sea ice on historical record.

Microplastic Research

“… plastic debris is often contaminated with toxic chemicals. Plastics can absorb and concentrate toxic pollutants present at trace levels in seawater, and some of the chemical additives mixed in during the manufacturing process can be toxic as well. When marine organisms ingest chemical-laden plastic pieces, some of the pollutants may be released within the gut of the animal and absorbed into body tissue. Although it is uncertain how much of these harmful chemicals enter marine animals due to ingestion of plastic debris in the ocean, laboratory experiments suggest there may be reason for concern.”
