The ‘river of grass’ wilderness and coastal communities are in peril, with the buffer coastal ecosystems on a ‘death march’ inland

Florida’s mangroves have been forced into a hasty retreat by sea level rise and now face being drowned, imperiling coastal communities and the prized Everglades wetlands, researchers have found.

Mangroves in south-east Florida in an area studied by the researchers have been on a “death march” inland as they edge away from the swelling ocean but have now hit a manmade levee and are likely to be submerged by water within 30 years, according to the Florida International University analysis.

Irma was a long-lived Cape Verde hurricane that reached category 5 intensity on the Saffir-Simpson Hurricane Wind Scale. The catastrophic hurricane made seven landfalls, four of which occurred as a category 5 hurricane across the northern Caribbean Islands. Irma made landfall as a category 4 hurricane in the Florida Keys and struck southwestern Florida at category 3 intensity. Irma caused widespread devastation across the affected areas and was one of the strongest and costliest hurricanes on record in the Atlantic basin.

HEAT ISLANDS  Heat claims more lives than floods, hurricanes and other weather-related disasters. How will cities cope as temperatures rise?  ULTRAFORMA/ISTOCKPHOTO

When days and nights get too hot, city dwellers are the first to run into trouble

sciencenews.org - by AIMEE CUNNINGHAM - April 3, 2018

Since 1986, the first year the National Weather Service reported data on heat-related deaths, more people in the United States have died from heat (3,979) than from any other weather-related disaster — more than floods (2,599), tornadoes (2,116) or hurricanes (1,391). Heat’s victim counts would be even higher, but unless the deceased are found with a fatal body temperature or in a hot room, the fact that heat might have been the cause is often left off of the death certificate, says Jonathan Patz, director of the Global Health Institute at the University of Wisconsin–Madison.

As greenhouse gases accumulate in the atmosphere, heat’s toll is expected to rise. Temperatures will probably keep smashing records as carbon dioxide, methane and other gases continue warming the planet. Heat waves (unusually hot weather lasting two or more days) will probably be longer, hotter and more frequent in the future.

Sea levels will rise between 0.7 and 1.2 meters (27-47 inches) in the next two centuries even if governments end the fossil fuel era as promised under the Paris climate agreement, scientists said on Tuesday.

Early action to cut greenhouse gas emissions would limit the long-term rise, driven by a thaw of ice from Greenland to Antarctica that will re-draw global coastlines, a German-led team wrote in the journal Nature Communications . . .

 . . . By 2300, the report projected that sea levels would gain by 0.7-1.2 meters, even if almost 200 nations fully meet goals under the 2015 Paris Agreement, which include cutting greenhouse gas emissions to net zero in the second half of this century . . .
