New Study: ‘Internal Noise’ And Volcanic Forcing Can Trigger 10-15°C Warming Within Decades

New Study: ‘Internal Noise’ And Volcanic Forcing Can Trigger 10-15°C Warming Within Decades

Climate changes fostered by “unforced natural climate variability” may be more than an order of magnitude larger than the climate changes commonly attributed to anthropogenic forcing. In a new study, scientists have attempted to identify the mechanisms explaining Greenland’s many historical (~80,000-11,700 years ago) climate changes that amounted to 10-15°C “in a decade or two.” The warmer Greenland climate endured for centuries, and the ice she…

New Study: Greenland’s Past 50–59°F Abrupt Climate Swings Occurred Naturally

New study finds Greenland’s past 50–59°F climate swings were driven by natural variability, volcanic forcing, and internal noise.
