In May 2013, the international press has become alive to the fact that
there is a lot of unburnable fossil fuels. “Unburnable” carbon has
become a buzz word in The Economist and in The New York Times. If the
oil, gas and coal reserves are burnt at present speed, there is no
chance whatever of limiting carbon dioxide concentration below 500 ppm.
A large part of such reserves must remain in the ground. The Grantham
Institute of the London School of Economics has produced a report that
proves that the policies advanced since 1997 by Oilwatch to leave oil in
the soil were right, and announces that the money value of fossil fuels
reserves will necessarily come down if something is effectively done
against climate change. The Economist (4 May 2013, “Unburnable Fuels”)
dismisses “technological fixes” such as carbon sequestration and
geo-engineering.
When Svante Arrhenius, a Swedish chemist and Nobel laureate, published
the first articles on climate change in 1896, the carbon dioxide
concentration in the atmosphere was 300 parts per million (ppm). It is
now reaching 400 ppm and rising 2 ppm per year. Arrhenius announced that
by burning coal found underground, industrialised countries were
releasing more and more carbon dioxide in the atmosphere and that this
would increase temperatures. He could not know that in the twentieth
century coal burning worldwide would increase seven-fold or that in
addition to coal burning would be added much more oil and natural gas;
in addition to the effects of deforestation.
