With climate models predicting less snow, ski areas seek to adapt | Business

SPOKANE, Wash. – This winter should be good, with a 70-80% chance that a La Niña will bring buckets of snow. If that happens, skiers and boarders will be thrilled, especially after a lackluster winter last year. The millions of dollars that local ski resorts have invested in improvements will start to pay off. But […]

Understanding the abrupt climate change at the end of the Quaternary

Editors Vox is a blog of the AGU publications service. About 75,000 to 10,000 years ago, there was a series of sudden and dramatic changes in precipitation patterns in the tropics, possibly triggered by changes in the circulation of ocean waters. A recent article in Geophysical reviews examines the evidence for these “tropical hydroclimatic events” […]

Climate models overlook benefits of ‘warming’ CO2, says statistician

Rather than relying on models of climate change that could be the basis for extensive and costly regulations, policymakers should instead question these models, focusing on the legitimacy of their underlying assumptions.

Earth’s orbit affects millennial climate variability

There is ample geological evidence to show that Earth’s climate experienced millennial-scale variability superimposed on glacial-interglacial fluctuations during the Pleistocene. The magnitude of millennial climate variability has been linked to glacial cycles over the past 800 thousand years (kyr). For the period leading up to the mid-Pleistocene transition, when global glaciations were less severe but […]
