[ad_1] It may sound like something out of a science fiction movie, but real-life scientists have been busy working on a super-precise laser tractor beam system to change the path and direction of the lightning. There is also a very practical reason behind it: Lightning strikes are the leading natural …

[ad_1] Even if humanity stops emitting greenhouse gases tomorrow, the Earth will warm up for centuries to come and oceans will rise by meters, according to a controversial modeling study released Thursday. Natural factors of global warming – more heat-trapping clouds, permafrost melting and sea ice shrinkage – already set …

[ad_1] It appeared in 1973, seemingly out of nowhere: a hole in sea ice off the coast of Antarctica. But this was no ordinary hole. It was so big it could swallow California. The mysterious opening remained in effect for the next three winters. Then it seemed to largely disappear …
