And why might #Dolphins and #Orcas be pissed off? Might have something to do with rising ocean temperatures (affecting their food sources) and all the CRAP we've been dumping into the world's oceans!
Signs of the human era, from #nuclear fallout to #microplastics
AFP, 10/07/2023
Paris (AFP) – As scientists make the case that humans have fundamentally transformed the planet enough to warrant our own geological epoch, another question arises: is there anything left untouched by humanity's presence?
"Soaring #greenhouse gases, ubiquitous microplastics, pervasive "forever chemicals", the global upheaval of animals, even old #MobilePhones and chicken bones -- all have been put forward as evidence that the world entered the #Anthropocene, or era of humans, in the mid-20th century.
"Jan Zalasiewicz, a British #geologist who chaired the Anthropocene Working Group for over a decade, paused for a moment when asked if there was anywhere on Earth that lacked signs of human influence.
"'It's hard to think of a more remote place' than the #PineIslandGlacier in #Antarctica, Zalasiewicz told AFP.
"Yet when scientists drilled deep below the glacier's ice a few years ago, they found traces of #plutonium.
"It was lingering fallout from nuclear weapon tests that began in 1945, leaving behind a #radioactive presence unlike anything before.
"Zalasiewicz said these radionuclides represented perhaps 'the sharpest signal' to mark the start of the Anthropocene epoch 70 years ago."

#Thwaites and #PineIsland #Glaciers Rapid Melting Could Cause Four Foot Global Sea Level Rise
March 4, 2020
"Over the weekend of February 8-9, 2020, a significant calving event was observed by the European Space Agency’s Sentinel satellites on Thwaites’ neighbor #PineIslandGlacier. A 120-mile ice chunk—approximately the size of three San Franciscos—broke off the glacier’s front and splintered into several smaller icebergs, one of which was huge enough to receive its own name, B-49. Pine Island Glacier’s unstable state is evidenced by the diminishing time between calving events; prior events this century happened in 2001, 2007, 2013, 2015, 2017, and 2018. Between Thwaites and Pine Island, the amount of ice lost from Antarctica’s ice shelves is rapid and indicates a serious future threat. Both are susceptible to the encroachment of warm sea level because the “grounding line,” where the glaciers meet bedrock, lies below sea level. These two glaciers form the gateway to a large supply of frozen water on land that if released into the sea would cause global sea levels to rise by an estimated four feet. Although Pine Island Glacier appears to have stabilized for now, the threat of an increasingly unstable ice shelf yielding larger and larger icebergs (marine cliff instability) may cause dangerously fast losses of ice in West Antarctica."

🥥 I told all of you that #ClimateChange was a hoax.
The #PineIslandGlacier story of a #volcano under the glacier is the giveaway.

Active #Volcano Discovered Under #Glacier in #Antarctica
Antarctica Journal, February 19, 2023
"The #PineIslandGlacier has been melting due to a volcano heat source that researchers have found underneath the glacier in Antarctica. The volcanic activity was first noticed in 2007 and then verified in 2014. This volcanic activity was discovered by some scientists at the University of Rhode Island’s Graduate School of Oceanography. From January to March of 2014 scientists from the United Kingdom were aboard an icebreaker during the summer down in Antarctica. They were studying the melting of the ice shelf due to the heat from the volcano. Scientists noted that the last time there was volcanic activity under the Pine Island Glacier was about 2200 years ago. Researchers also found high amounts of helium in the sea water at the Pine Island Shelf. The volcanic activity is not considered the only reason for the melting of the ice shelf in Antarctica – #ClimateChange is also a factor.
"Scientists are not sure how the volcanic heat gets distributed under the bottom of the ice sheet. They do know for sure that the heat from the volcano is causing the ice to melt beneath the ice shelf. More studying is needed before they can understand why the volcano is causing the melting."
