New research suggests the planet has already exceeded 1.5 degrees of warming, the threshold parties to the 2015 Paris Accord agreed not to pass.

The scientists in the study examined centuries-old sea sponges, finding growth records that document changes in water temperature, acidity and carbon dioxide levels in the air.

The research calculated that we may have already hit 1.7 degrees above pre-industrial levels.

Indiana State University paleo oceanographer and co-author of the study Amos Winter spoke to Corin Dann.
