Trillions of dollars of known and extractable coal, oil and gas cannot be exploited if the global temperature rise is to be kept under the 2 degrees centigrade safety limit, a new report published in the journal Nature.
New research identifies which fossil fuel reserves must not be burned to keep global temperature rise under 2 degrees Celsius (3.6 degrees Fahrenheit), including over 90% of US and Australian coal and almost all Canadian tar sands. Trillions of dollars of known and extractable coal, oil and gas cannot be exploited if the global temperature rise is to be kept under the 2C safety limit, says a new report.
Vast amounts of oil in the Middle East, coal in the US, Australia and China and many other fossil fuel reserves will have to be left in the ground to prevent dangerous climate change, according to the first analysis to identify which existing reserves cannot be burned.
The new work reveals the profound geopolitical and economic implications of tackling global warming for both countries and major companies that are reliant on fossil fuel wealth. It shows trillions of dollars of known and extractable coal, oil and gas, including most Canadian tar sands, all Arctic oil and gas and much potential shale gas, cannot be exploited if the global temperature rise is to be kept under the 2C safety limit agreed by the world’s nations. Currently, the world is heading for a catastrophic 5C of warming and the deadline to seal a global climate deal comes in December at a crunch UN summit in Paris.
“We’ve now got tangible figures of the quantities and locations of fossil fuels that should remain unused in trying to keep within the 2C temperature limit,” said Christophe McGlade, at University College London (UCL), and who led the new research published in the journal Nature. The work, using detailed data and well-established economic models, assumed cost effective climate policies would use the cheapest fossil fuels first, with more expensive fuels priced out of a world in which carbon emissions were strictly limited. For example, the model predicts that significant cheap-to-produce conventional oil would be burned but that the carbon limit would be reached before more expensive tar sands oil could be used.
It was already known that there is about three times more fossil fuel in reserves that could be exploited today than is compatible with 2C, and over 10 times more fossil fuel resource that could be exploited in future. But the new study is the first to reveal which fuels from which countries would have to be abandoned. It also shows that technology to capture and bury carbon emissions, touted by some as a way to continue substantial fossil fuel use in power stations, makes surprisingly little difference to the amount of coal, oil and gas deemed unburnable

I am presently a Volunteer for Habitat for Humanity, Madison, Wisconsin.
I oppose all long (>500 miles) distance travel (via fossil fuel burning) for nonessential purposes and all ownership of more than one home.
I am opposed to militarism in any form particularly for the purpose of monetary gain.
I am a Strong believer in people everywhere having the right to speak their minds openly, without any fear of reprisal, regarding any concerns; especially against those in authority who are not acting for the public good?in a timely fashion and in all countries of the world not just the U S..
My identical twin, Pat, died in June 2009.
He was fired from his job with the National Weather Service despite having a long and successful career as a flood forecaster with the Kansas City National Weather Service. He took a new position in the Midwest Regional Office in Minneapolis.
Unfortunately, Pat’s work for the NWS went sour after he began to see the evidence for concern about rising global temperatures shortly after relocating to Minneapolis, and how they appeared to effect of flooding on the Red River that flows out of Canada before entering the U.S. in North Dakota.
. Pat and I conversed on a regular basis with other scientists on the Yahoo Group named “Climate Concern “ and by personal email. The NWS denied his recommendation to give his public presentation o n his research at the “Minneapolis Mall of America” in February 2000, which deeply affected h,im. I will h He strongly believed the information ought be shared with the public to which I concurred. That was the beginning of the vendetta against my brother, Patrick J. Neuman, for speaking strongly of the obligations the federal government was responsible for accurately informing the citizenry.
A way great similar response to my raising the issue of too many greenhouse gases being emitted by drivers of vehicles on Wisconsin highway system, my immediate supervisors directed: “that neither global warming, climate change nor the long term impacts upon the natural resources of Wisconsin from expansion of the state highway system were to be any part of my job requirements, and that I must not communicate, nor in a memorandum to all the bureau, shall any person who works in the same bureau I do communicate with me, neither verbally on the phone, by email.
