Already a threat to fish, mussels, and other marine creatures, low-oxygen “dead zones” are expected to increase in both size and number as greenhouse gas concentrations and global temperatures continue to rise.
Fish nursery. Bird sanctuary. Storm surge blocker. Maryland’s Blackwater Marsh Wildlife Refuge is all those things and more. And it could be completely underwater by the end of this century. A team of ecologists and climate experts is determined to find and conserve migration corridors for the critical wetland ecosystem.
As sea level has changed, so has the way we measure it. Here’s a look at some of the technologies climate and marine scientists have used to track Earth’s tides and global sea level over the past two centuries.
Super Typhoon Haiyan slammed into the east coast of Samar and Leyte Islands in the Phillippines with what may have been the highest recorded wind speed for a tropical cyclone at landfall. Haiyan, locally known as “Yolanda,” was the deadliest typhoon in the country’s modern record.
In 2013, global average sea level was 1.5 inches above the 1993-2010 average, which is the highest yearly average in the satellite record (1993-present). Overall, sea level continues to rise at a rate of one-eighth of an inch per year.
Why on Earth are climate scientists so interested in the West Antarctic ice sheet? This remote region of the seventh continent has been the subject of many recent research explorations--the results of which have been described in the news with words like “collapse,” “irreversible,” and “huge.”
If mid-century projections of sea level rise prove true for New York City, four times as many people may be living in the 100-year floodplain than were previously estimated based only on observed changes.
