After 40 years, a large ice-free area appears again in the Southern Ocean in mid-winter
US-American scientists have calculated that the Weddell Polynya would probably not occur again because of climate change.
Higher precipitation levels in the region and melting ice would decouple the surface from the deeper water layers.
However, in several studies applying the “Kiel Climate Model” and other computer models, the research group in Kiel described the polynya as part of long-term natural variability, which would occur again sooner or later. “The fact that now a large, ice-free area can be observed in the Weddell Sea confirms our theory and gives us another data point for further model studies,” says Dr. Martin.

Dear friends,
After the April USA solar induced blackout, McGill University started an international campaign to
“create solar shields against coronal mass ejections”, and an extinction!

8 institutions have already started the simulations on the ultimate truce tool: Laser Earth Shield vs all deadly space threats, as asteroids, comets and solar superstorms that may blow up all nuclear, as we thankfully escaped in July 2012! But there’s still no world congress on TRUCE and Shield, even there are ALREADY 30 superlasers* that may start shielding humankind!
Shall we wait for the next medium solar storm to cause another April-like USA blackout???
8 institutions in 3 countries started Earth laser-Shield simulations.

To produce the wave, scientists used a laser to create a high-energy plasma—a form of matter composed of atoms and charged atomic particles—that expanded into a pre-existing magnetized plasma.

I can’t help but notice that you’ve dispensed with the global ice metric and that there’s a seemingly artificial positivity to these reports lately. What gives?
