https://www.washingtonpost.com/news/energy-environment/wp/2016/05/02/dominoes-fall-vanishing-arctic-ice-shifts-jet-stream-melts-greenland-glaciers/Investigating the factors affecting ice melt in Greenland one of the most rapidly changing places on Earth is a major priority for climate scientists. And new research is revealing that there are a more complex set of variables affecting the ice sheet than experts had imagined. A recent set of scientific papers have proposed a critical connection between sharp declines in Arctic sea ice and changes in the atmosphere, which they say are not only affecting ice melt in Greenland, but also weather patterns all over the North Atlantic.
The new studies center on an atmospheric phenomenon known as blocking this is when high pressure systems remain stationary in one place for long periods of time (days or even weeks), causing weather conditions to stay relatively stable for as long as the block remains in place. They can occur when theres a change or disturbance in the jet stream, causing the flow of air in the atmosphere to form a kind of eddy, said Jennifer Francis, a research professor and climate expert at Rutgers University.
Blocking events over Greenland are particularly interesting to climate scientists because of their potential to drive temperatures up and increase melting on the ice sheet.
When they do happen, and they kind of set up in just the right spot, they bring a lot of warm, moist air from the North Atlantic up over Greenland, and that helps contribute to increased cloudiness and warming of the surface, Francis said. When that happens, especially in the summer, we tend to see these melt events occur.

I'm only 36, in great shape physically, and come from a very long-lived family, so I have the genetics to make it into my 90's.
My retirement plans are looking more and more like this:

extended family. Learn how to do things that are useful, skills. Garden now so you know how.
