_According to a recent government report, the US might suffer effects of the abrupt climate change, which is sooner than few have guessed.

It contends that the seas could increase quickly if polar ice melting continuously outruns new projections and an ongoing drought in the US might be the start of drying in the region. Accredited by the US Climate Change Science Program, the report was written by experts from the Columbia University's Lamont-Doherty Earth Observatory, US Geological Survey, and some leading institutions.

Several scientists are lifting the possibility that catastrophic, abrupt switches in the natural systems might stress the rise of global temperatures. The report utilises studies, which is not available in the Intergovernmental Panel on Climate Change (IPCC). “This is the most up to date, as it includes research that came out after IPCC assembled its data”, said climatologist Edward Cook of Lamont-Doherty.

The researchers state that IPCC’s estimate of two feet of sea level increase by 2100 might be exceeded, because the recent data implies that the polar ice melting is increasing. There is evidence showing that the Antarctic ice cap is now losing an overall mass.

Cook states that the periodic drought in over 1,000 years is driven by natural cycles in the air circulation. “We have no smoking gun saying that humans are causing the current changes. But the past is a cautionary tale”, Cook state. “What this tells us is that the system has the ability to lock into periods of profound, long-lasting aridity.
