There’s been little let-up in the global wave of coral bleaching that’s been ongoing in various parts of the world since 2014, according to an update from NOAA’s Coral Reef Watch program. To date, the bleaching is the most widespread and damaging on record, including mass bleaching in areas where it’s never been seen before — the northern Great Barrier Reed, Kiribati and Jarvis Island.

And more of the same is expected in in the next few months as the Northern Hemisphere moves toward summer. Based on forecasts for the next two to three months, bleaching is likely in the eastern Pacific. Widespread coral bleaching with significant mortality continues in the Samoas (where bleaching of both shallow and deeper corals has now been confirmed) but is expected to dissipate shortly.

After extensive damage to the Great Barrier Reef, ocean temperatures finally cooled of in April, giving a respite to the corals that survived. Similarly, the corals around Florida also got some relief in the past few months. Get the full update at the NOAA coral reef watch page.
