It's hard stuff in life. In a Ice Age comes viruses that took out the inbreeds being less diversity with the cave men, a bottle neck very sickly! Then in global warming comes all the nastiest that lay on the bottom that will be exposed to the air soon! Warm waters is a Petri dish, natures agar plates for us! And so is the risk from global warming!
This is something people should know! Last month in Tulsa by the Arkansas river the water was held back for construction so the river bed was exposed in the heat of the day and you could smell it. Thinking of brain-eating amoebas I got out of there! But people where still walking around! Like today not using a mask. Is it no self esteem? And is the point to be more self aware about what is going on!
~~~~~At the end of July, 40% of the 4,000-year-old Milne Ice Shelf, located on the north-western edge of Ellesmere Island, calved into the sea. Canada’s last fully intact ice shelf was no more.
On the other side of the island, the most northerly in Canada, the St Patrick’s Bay ice caps completely disappeared.
Two weeks later, scientists concluded that the Greenland Ice Sheet may have already passed the point of no return. Annual snowfall is no longer enough to replenish the snow and ice loss during summer melting of the territory’s 234 glaciers. Last year, the ice sheet lost a record amount of ice, equivalent to 1 million metric tons every minute.
The Arctic is unravelling. And it’s happening faster than anyone could have imagined just a few decades ago. Northern Siberia and the Canadian Arctic are now warming three times faster than the rest of the world. In the past decade, Arctic temperatures have increased by nearly 1C. If greenhouse gas emissions stay on the same trajectory, we can expect the north to have warmed by 4C year-round by the middle of the century. https://www.theguardian.com/us-news/ng-interactive/2020/oct/13/arctic-ice-melting-climate-change-global-warming
~~~~~As the Earth warms, more permafrost will melt. Under normal circumstances, superficial permafrost layers about 50cm deep melt every summer. But now global warming is gradually exposing older permafrost layers.
Frozen permafrost soil is the perfect place for bacteria to remain alive for very long periods of time, perhaps as long as a million years. That means melting ice could potentially open a Pandora's box of diseases. http://www.bbc.com/earth/story/20170504-there-are-diseases-hidden-in-ice-and-they-are-waking-up
