Before your eyes. what is happening? we are starting to measure warming gases that trap the heat in the earth higher than any recorded time in history. 800,000 years we have ice core, tree ring simples and other biological data that allows us to measure that over the thousands and millennium of years. coming from electricity, agriculture, fossil fuels. i think we all felt it before you came out with the data that proves it. absolutely. go outside. derek, thank you. japanese researchers are looking at something lost to all of us millions of years ago. they are look to bring it back courtesy of robotics. millions of years after ....
Changing, changing faster than the science and the studies can keep up with. the team drilled through the ice to measure thickness. we re starting to get a fairly good idea. it has definitely thinned in this area as well, basically thinned everywhere. reporter: extracting ice that holds frozen clues. wow. look at this. beautiful. about a meter of ice core here. inside this piece of ice is a microscopic forest. reporter: greenpeace ship the arctic sunrise is converted into a floating lab. all right. grab the first one. melted ice core samples come to life, a kaleidoscope of sea ice and fight toe plankton. ....
Together a puzzle. these pieces are constantly changing. changing faster than the science and the studies can keep up with. reporter: the team drove through the ice to measure thickness. we re starting to get a pretty good idea. it has definitely thinned in this area as well. it s basically thinned everywhere. reporter: extracting ice cores that hold frozen clues. beautiful. about a meter of ice core right here. and inside this piece of ice, is a little microscopic forest. reporter: greenpeace arctic sunrise, is converted into a floating lab. can you grab the first one? reporter: melted ice core samples come to life under the microscope. a kaleidoscope of algae and ....
To measure thickness. it has definitely thinned in this area as well. it s basically thinned everywhere. extracting ice cores that hold frozen clues. wow, look at this. beautiful. that s about a meter of ice core here. inside is a microscopic foreign. greenpeace arctic sunrise is converted into a floating lab. all right. can grab the first one. reporter: melted ice core samples come to life. a kaleidoscope of algae and phytoplankt phytoplankton. they re tremendously important for carbon drawdown. they takes in the carbon dioxide. reporter: phytoplankton just ....
Question. has the arctic reached a tipping point? engineer zoe korville has explained its isolation is its greatest asset. it s a pristine of climate change specifically. we ve been making measurements since 1980 here. we ve also drilled to bedrock. so we have 140,000 years? yes, we re standing on two miles of ice below us. and you can use ice core as tree rings to get an idea of what it was like. but summit s hefty price tag has made it a pro po sal for ....
