Study: Recent global warming ‘unprecedented’ in 24,000 years

Washington: The speed of human-caused global warming over the last 150 years is faster than anything seen since the last ice age, about 24,000 years ago, according to a study.

The team led by researchers at the University of Arizona, US, also verified that the main drivers of climate change since the last ice age are rising greenhouse gas concentrations and the retreat of the ice sheets.

The study, published recently in the journal Nature, suggests a general warming trend over the last 10,000 years, settling a decade-long debate about whether this period trended warmer or cooler in the paleoclimatology community.
