the national oceanic and atmospheric administration, known as noaa, has boosted its atlantic hurricane season forecast saying it is more likely we ll see more hurricanes this year. the above-normal forecast comes because of record warming ocean temperatures. allison chinchar joins us. tell us more. going into the season, they first forecast in may and do an upgrade in august. it happens every year. but back in may, we knew ocean temperatures were warm but it was going to be an el nino year, and that suppresses hurricane activity. i think what they re noticing is those ocean temperatures are so far above normal that they re thinking that s likely going to be able to compensate for whatever el nino may try to suppress. they did increase their numbers. there were 12 to 17 named storms. now 14 to 21. the low end, 14, is what we
Australia's Great Barrier Reef could deteriorate if warming ocean temperatures spark another mass coral bleaching event later this year, the country's top marine science body said Wednesday. Marine heatwaves have caused mass coral bleaching on the Great Barrier Reef in 2016, 2017, 2020 and 2022.
signs of damage from pollution or from warming ocean temperatures, something that poses a major threat to shallower reefs. it looks beautiful, but scientifically how important is this, as a discovery? it might be to date one of the largest coral reefs in the world that actually lies that the sort of depth at that sort of depth of more than 30 metres, so from that perspective, this is opening a new insight in science. this could suggest that we have many more large reefs in our ocean, at depths beyond 30 metres, which we simply do not know about. the depth of this reef means there is far less sunlight here than in the shallows. this part of the ocean is known as the twilight zone. there s stilljust enough light here for the algae that lives inside the bodies of the coral to survive and thrive. and critically, for the health of this reef, waters at these depths are not warming as quickly.
to describe this view. some of these rose shaped corals are more than two metres wide, and the whole reef structure stretches three kilometres along the sea bed. its depth and its distance from the coast is thought to be a key reason for its pristine condition. the researchers say it shows no signs of damage from pollution or from warming ocean temperatures, something that poses a major threat to shallower reefs. it looks beautiful, but scientifically how important is this, as a discovery? it might be, to date, one of the largest coral reefs in the world that actually lies at that sort of depth of more than 30 metres. so, from that perspective, that is opening a new insight in science. this could suggest that we have many more large reefs in our ocean, at depths beyond 30 metres, which we simply do not know about. it s often said we know more about the surface of the moon
