Ice cores reveal clues about how Earth’s climate has evolved

CNN  

Editor’s note: A version of this story appeared in CNN’s Wonder Theory science newsletter. CNN — One of the best ways to assemble the puzzle pieces of Earth’s past is hiding deep beneath its white polar sheets: ice cores. Air bubbles and particles trapped inside the ice could also reveal why the planet’s ice ages suddenly became longer and more intense about 1 million years ago, which may have caused ancient human populations to plummet. The uncrewed vehicle, named New Glenn after storied NASA astronaut John Glenn, will mark the first attempt by Jeff Bezos’ company Blue Origin to send a rocket into orbit. The company’s most powerful rocket could one day be used to ferry Amazon internet satellites to space or assist in constructing a space station Blue Origin is developing with its partners.
