And the major shifts happen over just 12 years once the tipping points are hit. But major climate shifts rather than just the transition to and from ice ages usually take a million years and everything has times to move or evolve. This is happening too fast. A big concern is the methane hydrate ice under the Arctic Ocean, that once released 5 or 600 million years ago leading to the largest extinction event after the earth warmed up almost 20 degrees Celsius in a very short time worldwide.
