There is very slim chance left to avoid global warming, study finds

The study uses statistical projections based on total world population

Their analysis - published this week in the journal Nature Climate Change - suggests there is only a 5 percent chance Earth warms by less than 2 degrees.

Climate change is often associated with impending dangers such as heat stress, severe storms, flooding, inhibited access to clean water and food, and the spread of infectious diseases.

"Our analysis shows that the goal of 2 degrees (Celsius) is very much a best-case scenario", Raftery said. "We are closer to the margin than we think", Raftery said.

The first study took into account statistics of chances of warming by the year 2100 and considered three main issues: global population, people per country and carbon intensity which is emitted by the economy of each of the countries. Statistical projections were made on the basis of data for the last 50 years.

It has been revealed that scientists had been using wrong baseline temperature; they started measuring global warming in 1900 - after nearly a hundred years since industrial revolution began when fossil fuels were burnt in large amounts.

The biggest factor was found to be carbon intensity, which has been dropping in recent years due to increased energy efficiency across industries.

Technological advances are expected to cut global carbon intensity by 90pc over the course of the century, with sharp declines in China and India - two newly voracious consumers of energy.

Warming beyond 3.6 degrees Fahrenheit, or 2 degrees Celsius, is viewed as the "tipping point" at which the side effects of climate change become more extreme.

Mauritsen, author of the second study, noted that even though Carbon dioxide has a long lifetime in the atmosphere, the ocean's absorption capacity could reduce estimates of global warming by 0.2 degrees C. Mauritsen and his co-author, Robert Pincus, arrived at an estimated warming of 1.3 degrees by 2100, along with the estimated ocean factor of 1.1 degrees C. To make matters worse, the study has speculated a peak in death toll with a projected 60,000 globally in 2030 and 260,000 by 2100. The researchers noted there's only a 1 percent chance the temperature will only increase less than 1.5 degrees Celsius.

"This "committed warming" is critical to understand because it can tell us and policymakers how long we have, at current emission rates, before the planet will warm to certain thresholds". If current emission levels continue for 15 years, the planet would likely experience almost 3 degrees Fahrenheit of warming by 2100.

A study by global scientists has dropped the bombshell that temperature rise around the globe is nearly inevitable as the industries and vehicles emit carbon fumes relentlessly along with skyrocketing population growth in recent years.

McKibben also said humanity should fight global warming like it's Word War III, an effort he saw as similar to how the Allies fought the Nazis and Japanese in World War II.

"Our work shows that there isn't much more room for emissions before making those targets unachievable", said Robert Pincus, an atmospheric scientist with the Cooperative Institute for Research in Environmental Sciences, a partnership between the University of Colorado and the federal National Oceanic and Atmospheric Administration.
