| Climate changed abruptly at tipping points in past Posted: 16 Nov 2021 08:14 AM PST Climate scientists identify abrupt transitions in climate records that may have been caused by the climate system crossing a tipping point. They devised a statistical method to determine whether these transitions are simply noise or evidence of a more significant change. Their method is less error-prone than previous methods, since it doesn't rely on human determination. It also allows comparing different records consistently and can identify important events that may have been overlooked in older studies. |

Then, tens of millions of years later, the Sierra Nevada mountain range as we know it today was 'reborn.' |
