Australia’s marine heatwaves provide a glimpse of the new ecological order

For the second year in a row, a stubborn high-pressure system over the Tasman Sea was warming the surface of the ocean to above-average temperatures, forming a marine heatwave, wreaking destruction and providing a glimpse of the new ecological order in the marine Anthropocene. Globally marine heatwaves are becoming more frequent and prolonged and affecting biodiversity, according to new research published in Nature Climate Change this week.

as more heat and water get under the glacier, it melts faster

Cavity two-thirds the size of Manhattan discovered under Antarctic glacier

Disintegration of rapidly melting Thwaites ice mass could threaten coastal communities worldwide — Scientists have discovered a giant cavity at the bottom of a disintegrating glacier in Antarctica, sparking concerns that the ice sheet is melting more rapidly than expected. Researchers working as part of a Nasa-led study found the cavern, which they said was …

Rising temperatures to make oceans bluer and greener

Scientists say effects of global warming on ‘phytoplankton’ will intensify the colours — The blues and greens of the ocean will become even bluer and greener by the end of the century as a result of global warming, scientists have found. Researchers say the colour changes are down to the effect of climate change on …

Cod stocks on course to crash if ocean warming continues

Barents Sea is key source of UK cod imports and could see temperature rises of over 6°C — Fish fingers and cod and chips are under a far greater threat from carbon emissions than previously thought, according to a recent study that has grave implications for food security. The North Atlantic cod stock in the …

A Novel Approach Reveals Element Cycles in the Ocean

Dissolved thorium isotopes light the way to a more thorough understanding of how different elements enter marine environments—and how long they stay there — The ocean covers 72% of Earth’s surface and plays a vital role in global biogeochemical cycles. The carbon and nitrogen cycles receive ample attention because of their impact on the climate …

Our oceans broke heat records in 2018 and the consequences are catastrophic

Rising temperatures can be charted back to the late 1950s, and the last five years were the five hottest on record — Last year was the hottest ever measured, continuing an upward trend that is a direct result of manmade greenhouse gas emissions. The key to the measurements is the oceans. Oceans absorb more than …
