Modern mountain climbers usually carry tanks of oxygen to help them reach the summit. The combination of physical exertion and lack of oxygen at high altitudes creates a major challenge for mountaineers. Now, just in time for World Oceans Day on Monday, June 8, researchers have found that the same principle applies to marine species during climate change.
Warmer water temperatures will speed up the animals' metabolic need for oxygen, as also happens during exercise, but the warmer water will hold less of the oxygen needed to fuel their bodies, similar to what happens at high altitudes.Image credit: Wikimedia Commons
