Below is the start of a report about February's record high ocean surface temperatures likely sparking yet another mass coral bleaching in tropical reef systems, including Australia's Great Barrier Reef.

the report was published overnight on InsideClimateNews.org. The headline is mine with the report written by Kiley Price.

Great Barrier Reef In 5th Mass Coral Bleaching in 8 Years.

"For the past nine months, the world has repeatedly smashed heat records on land.

"But February marked a particularly unsettling record for the ocean: Average global sea surfaces climbed to the hottest temperatures ever recorded of any month since at least 1979, according to the Copernicus Climate Change Service.

" Fueled by El Niño conditions and climate change, these ocean temperatures are now pushing the world toward its fourth mass coral bleaching event, the National Oceanic and Atmospheric Administration announced on March 5.

""It’s looking like the entirety of the Southern Hemisphere is probably going to bleach this year,” Derek Manzello, the coordinator of NOAA’s Coral Reef Watch, told Reuters. “We are literally sitting on the cusp of the worst bleaching event in the history of the planet.”

"Three days later, officials in Australia confirmed that the Great Barrier Reef has already barreled past that cliff, and is in the midst of its fifth mass coral bleaching event in the past eight years.

" Scientists are especially worried about what this one could mean for the future of the world’s largest reef."

Let me give you the drum about El nino conditions in East Aust.

It means that the atmosphere in the West pacific has a HELL of a lot LESS moisture in the atmosphere.
I.e LESS GHG effect. However what is FACT during these periods is that there is a greater ASR or Absorbed solar radiation.

Sorry Bell I know that maybe a little too complicated for you to grasp.

So in a nutshell.
La Nina - More clouds, more rain, greater amount of ghg effect and to finish off cooler weather.
El Nino - Less Rain, Less clouds, less GHG Effect and greater ASR. thus hotter conditions.

What have you learnt LIQ.
