This finding can not be explained by natural climate variability alone, the study found, and is instead consistent with global warming

«We know that it is important to distinguish between human - caused and natural climate variability so we can assess the impact of human - caused climate change, including drought and weather extremes,» Professor Mann said.

He further claims that natural climate variations have been forgotten and attributes recent warming to the «rebounding effect from the little ice age», but fails to realize that natural climate variability also has a cause.
