‘Greater warming': different species under threat

Entire ecosystems are under threat due to warming oceans with parts of the Australian coast stretching from Sydney to Adelaide experiencing the most stress, experts warn.

Eight of the 10 warmest years of sea surface temperatures have been recorded since 2010 contributing to coral bleaching, oceans acidifying and altering the habitats of different species, a joint study by the Bureau of Meteorology and CSIRO has found.

"The warming has been most noticeable, particularly around the south-east of the continent, and it's not just coral reefs that are impacted but kelp forests and commercial fisheries," the bureau's head of climate monitoring, Dr Karl Braganza, said.

Sharks are thriving in Southern California but dying in the San Francisco Bay, experts say

A warming planet impacts on everything.

For weeks, hundreds of sharks have been washing
 up dead on the shores of the San Francisco Bay. 

Evidence is abundant how Earth’s changed climate system is manifesting what might be called “weird weather” around the globe and species from the almost invisible to our peak predators, including the oceans sharks, are changing their habits.

And now it is evident that our warming oceans are bringing young sharks closer to our shores for the abundant food supplies, and or course they are bringing their larger counterparts with them.

Scientists concerned about rapidly waming oceans

his week, scientists registered their concern that super-warm conditions are building to a point where corals are severely threatened across the tropical Indian, Pacific and Atlantic oceans.

They did so after seeing corals lose colour across the three major ocean basins – a sign of a truly momentous global change.

This is only the third global bleaching event in recorded history.
