Reduced Oxygen During Ice Age Sheds Light on ‘Missing’ Carbon Dioxide

Posted on: March 31, 2016

Tiny ocean dwellers witnessed climate cycles, report past conditions

Climate is not constant on Earth. Consider ice ages coming and going as an example. Parallel to ice age cycles, atmospheric carbon dioxide reduces during glacial periods and increases during warmer times, although modern fossil fuel-related carbon dioxide emission broke this natural cyclicity. With the proper proxy measurements, scientists can look into these past cycles to determine how exactly climate systems were naturally governed. Read more...
