‘Completely Terrifying’: Study Warns Carbon-Saturated Oceans Headed Toward Tipping Point That Could Unleash Mass Extinction Event

July 09, 2019 by Julia Conley, staff writer, Common Dreams “Once we’re over the threshold…you’re dealing with how the Earth works, and it goes on its own ride.” The Atlantic coast near Galicia, Spain. A study by an MIT researcher warns that humans are pumping carbon into the world’s oceans at a rate that could trigger a mass extinction event. …

Global warming increases microbial activity, driving global warming feedback loops: accelerated microbial activity in soils will significantly increase carbon emissions by 2050.

BY BOB BERWYN, INSIDECLIMATE NEWS JUN 19, 2019 All life on Earth evolved from microorganisms in the primordial slime, and billions of years later, the planet’s smallest life forms—including bacteria, plankton and viruses—are still fundamental to the biosphere. They cycle minerals and nutrients through soil, water and the atmosphere. They help grow and digest the food we eat. Without microbes, …

Substantial increase in minimum lake surface temperatures under climate change  (Climate Change) The average surface temperature of European lakes has risen by 0.35C per decade since the early 1970s, a new study finds. The researchers analysed observational data for 1973-2014 from eight European lakes, finding rising annual and summer average temperatures – as well as increases in annual minimum lake surface …

George Monbiot: Stop eating fish until the fishing industry is regulated and fishing is prohibited in open ocean areas. 

Regulating the fishing industry is both cheap and easy. If commercial fishing were excluded from large areas of the sea, the total catch would be likely, paradoxically, to rise, due to what biologists call the spillover effect. Fish and shellfish breed and grow to large sizes in the reserves, then spill over into surrounding waters. Where seas have been protected …

By Kristian Teleki It’s easy to lose sight of good news amid the barrage of negative stories about the threats facing the ocean—everything from growing plastic pollution to dying coral reefs. However, there is a lot …

Study of Antarctic sea ice collapse warns of potential 10-foot sea rise, with rate of ocean warming up 50% since 1991.

Gigantic hole two-thirds the size of Manhattan discovered in Antarctic glacier, Sheena McKenzie, CNN, January 31, 2019 (CNN) A massive cavity two-thirds the size of Manhattan has been discovered growing in an Antarctic glacier, signaling rapid ice decay that has shocked scientists. The huge hole — measuring almost 1,000 feet (300 meters) tall — was found growing at an “explosive rate” at the …

Antarctic Losing 6x as Much Ice as in the 80s, World’s Oceans Are Warming Faster, Studies Show, Fueling Storms and Sea Rise:  ‘Global warming is here, it has major consequences, and it’s going to be very, very difficult to get this under control,’ an author of a new report says

Even more: Compared to just last year, the Antarctic ice is melting 15 percent faster, with East Antarctica—previously found to be relatively stable from year to year—now losing 56 billion tons of ice per year. Eric Rignot told CNN that he had not expected ice in the eastern part of the continent to be melting at such an alarming rate. Wednesday, January 16, 2019 Common …

Gulf Stream current at its weakest in 1,600 years, studies show. AMOC weakening should be avoided at all costs say scientists

Gulf Stream current at its weakest in 1,600 years, studies show Warm current that has historically caused dramatic changes in climate is experiencing an unprecedented slowdown and may be less stable than thought – with potentially severe consequences Damian Carrington, The Guardian, Environment editor, Wed 11 Apr 2018  The warm Atlantic current linked to severe and abrupt changes in the climate in …

Global warming of oceans equivalent to an atomic bomb per second: Seas absorb 90% of climate change’s energy as new research reveals vast heating over past 150 years

Damian Carrington, Mon 7 Jan 2019  Global warming of oceans equivalent to an atomic bomb per second: Seas absorb 90% of climate change’s energy as new research reveals vast heating over past 150 years, in The Guardian, 7 Jan 2019 A Guardian calculation found the average heating across that 150-year period was equivalent to about 1.5 Hiroshima-size atomic bombs per second. …
