New climate study finds higher expected temperature rise (up to 7C) by the year 2100

Instead of a 4C increase by 2100 this study found a new range of 4.78C to 7.36C. Summary is that the climate is maybe more susceptible to greenhouse gasses than originally thought.

According to the current best estimate, by the Intergovernmental Panel on Climate Change (IPCC), if humans carry on with a “business as usual” approach using large amounts of fossil fuels, the Earth’s average temperature will rise by between 2.6 and 4.8 degrees above pre-industrial levels by 2100.

However new research by an international team of experts who looked into how the Earth’s climate has reacted over nearly 800,000 years warns this could be a major under-estimate.

Because, they believe, the climate is more sensitive to greenhouse gases when it is warmer.

In a paper in the journal Science Advances, they said the actual range could be between 4.78C to 7.36C by 2100, based on one set of calculations.

Some have dismissed the idea that the world would continue to burn fossil fuels despite obvious global warming, but emissions are still increasing despite a 1C rise in average thermometer readings since the 1880s.

And US President-elect Donald Trump has said he will rip up America’s commitments to the fight against climate change.

Professor Michael Mann, of Penn State University in the US, who led research that produced the famous “hockey stick” graph showing how humans were dramatically increasing the Earth’s temperature, told The Independent the new paper appeared "sound and the conclusions quite defensible".

“And it does indeed provide support for the notion that a Donald Trump presidency could be game over for the climate,” he wrote in an email. “By ‘game over for the climate’, I mean game over for stabilizing warming below dangerous (ie greater than 2C) levels.

“If Trump makes good on his promises, and the US pulls out of the Paris [climate] treaty, it is difficult to see a path forward to keeping warming below those levels.”

Reminder that just a 2 percentage increase in temperature is considered catastrophic for the human race. If it raises anymore mankind will face dire consequences by the year 2100.

Anyone who has grandchildren at this point will be facing this future. Pray for your future grandkids, if you have any.
