Global Warming
Steve Connor, Science Editor of the Independent, wrote: Professor Paul Crutzen, who won a Nobel Prize in 1995 for his work on the hole in the ozone layer, believes that political attempts to limit man-made greenhouse gases are so pitiful that a radical contingency plan is needed. In a polemical scientific essay that was published in the August 2006 issue of the journal Climatic Change, he says that an "escape route" is needed if global warming begins to run out of control.
Professor Crutzen has proposed a method of artificially cooling the global climate by releasing particles of sulphur in the upper atmosphere,along with other particles at lower atmospheric levels, which would reflect sunlight and heat back into space. The controversial proposal is being taken seriously by scientists because Professor Crutzen has a proven track record in atmospheric research. If this artificial cooling method actually were to work, then we would be able to help reverse the effects of the pollution caused by the burning of fossil fuels, buying us time to find a permanent energy replacement. This could be crucial in helping maintain the planet's integrity and livability.
In January 2008, Crutzen published findings that the release of nitrous oxide (N2O) emissions in the production of biofuels means that they contribute more to global warming than the fossil fuels they replace.

Famous quotes containing the words global and/or warming:
“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
“Thine age asks ease, and since thy duties be
To warm the world, that’s done in warming us.
Shine here to us, and thou art everywhere;
This bed thy center is, these walls, thy sphere.”
—John Donne (1572–1631)
