The Great Barrier Reef is in the grip of a mass coral bleaching event driven by global heating – the fifth in only eight years – the marine park’s…Continue readingFifth mass coral bleaching event in eight years hits Great Barrier Reef, marine park authority confirms
Many traditional Malaysian fishermen have found themselves increasingly affected by the climate crisis, which is changing weather patterns that have long governed when and where they can fish. Such…Continue readingClimate change pushes Malaysia’s coastal fishermen away from the sea
Ocean currents are driven by winds, tides and water density differences. In the Atlantic Ocean circulation, the relatively warm and salty surface water near the equator flows toward Greenland.…Continue readingOnce melting glaciers shut down the Gulf Stream, we will see extreme climate change within decades

The water off South Florida is over 90 degrees Fahrenheit (32 Celsius) in mid-July, and scientists are already seeing signs of coral bleaching off Central and South America. Particularly…Continue readingCorals are starting to bleach as global ocean temperatures hit record highs
Approximately 40% [25%] of the global ocean is currently experiencing MHWs, which ranks 1st [14th] among all months since 1991. Values include the effects of long-term warming. Values with…Continue readingCurrent marine heatwave (MHW) conditions
