New findings reveal climate change is accelerating at never before seen rates in 1,000 years.

Climate scientists warn that by 2020, global temperatures will rise half a degree every decade, which is twice the rate observed in the last 900 years.

More than two dozen climate models were carefully studied by climate scientists. They conclude human activity is causing and releasing massive quantities of carbon high into the atmosphere and this leads to climate change and warmer temperatures.

Computer simulation models can show the effects of carbon on the environment but short term weather patterns and variations make it more difficult to predict global warming trends.

Researchers calculated the base rate of global warming from 1850 to 1930 and said man-made emissions of atmospheric carbon were significantly lower than the next decades following the industrial revolution.

Evidence such as tree rings, ice cores and corals were examined to determine a record of global temperatures spanning 2,000 years. Investigators discovered that prior to the start of the 20th century, temperatures did not exceed more than 0.18 degrees for each decade.

Using calculations from this extensive database, scientists now predict that global temperatures will rise at an average of 0.45 degrees Fahrenheit every 10 years in the next coming decades.

Even if the lowest likely carbon rates in the next decades were used, climate models still present rising global temperatures in the future. Higher estimates from the climate models naturally result in greater carbon levels as opposed to lower levels.

Models predict that nearly every region in the world will experience rising temperatures beyond natural fluctuations and will accelerate over time. The study aims to make people aware and to prepare them for the onslaught of rising global temperatures in the next 40 years or so.

According to Steve Smith of the Pacific Northwest National Laboratory under the U.S. Department of Energy, these climate model simulations show temperatures can rise in 40 year life spans.

This study was published in the journal, Nature Climate Change.
