American scientists studying past and future weather patterns have warned hurricane conditions could get bigger, stronger and wetter.

Researchers at the National Centre for Atmospheric Research (NCAR) have published a detailed analysis of how 22 recent hurricanes would change if they instead formed near the end of this century. And while each storm’s transformation would be unique, on balance, the hurricanes would become a little stronger, a little slower moving, and a lot wetter.

With the start of hurricane season just three weeks away — and memory of last year's disastrous storms still fresh — scientists reported that powerful hurricanes are strengthening faster than they did 30 years ago.

Four of the monster hurricanes last year (Harvey, Irma, Jose and Maria) all intensified rapidly — when the maximum wind speed increases at least 29 mph within 24 hours . . .

 . . . According to a study out this week, the main cause appears to be a natural climate phenomenon that warms the seawater where hurricanes typically intensify in the Atlantic.

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.
