Too Little for Global Warming
Oil and gas will run out too fast for doomsday global warming scenarios to materialize, according to a controversial new analysis presented this week at the University of Uppsala in Sweden. The authors warn that all the fuel will be burnt before there is enough carbon dioxide in the atmosphere to realize predictions of melting ice caps and searing temperatures. Defending their predictions, scientists from the Intergovernmental Panel on Climate Change say they considered a range of estimates of oil and gas reserves, and point out that coal-burning could easily make up the shortfall. But all agree that burning coal would be even worse for the planet.
The IPCC's predictions of global meltdown pushed forward the 1997 Kyoto Protocol, an agreement obliging signatory nations to cut CO2 emissions. The IPCC considered a range of future scenarios, from unlimited burning of fossil-fuels to a fast transition towards greener energy sources. But geologists Anders Sivertsson, Kjell Aleklett and Colin Campbell of Uppsala University say there is not enough oil and gas left even the most conservative of the 40 IPCC scenarios to come to pass.
Although estimates of oil and gas reserves vary widely, the researchers are part of a growing group of experts who believe that oil supplies will peak as soon as 2010, and gas soon after. Their analysis suggests that oil and gas reserves combined about to the equivalent of about 3,500 billion barrels of oil considerably less than the 5,000 billion barrels estimated in the most optimistic model envisaged by the IPCC. Even the average forecast of about 8,000 billion barrels is more than twice the Swedish estimate of the world's remaining reserves.
Nebojsa Nakicenovic, an energy economist at the University of Vienna, Austria who headed the 80-strong IPCC team that produced the forecasts, says the panel's work still stands. He says they factored in a much broader and internationally accepted range of oil and gas estimates than the "conservative" Swedes.
Even if oil and gas run out, "there's a huge amount of coal underground that could be exploited", he says that burning coal could make the IPCC scenarios come true, but points out that such a switch would be disastrous. Coal is dirtier than oil and gas and produces more CO2 for each unit of energy, as well as releasing large amounts of particulates. He says the latest analysis is a "shot across the bows" for policy makers.
What problem does the authors of the new analysis raise？
A．The coal reserves are big enough.
B．All the fuel will be burnt before there is enough carbon dioxide.
C．Coal-burning could easily make up the shortfall of oil and gas reserves.
D．Oil and gas will run out so fast that Earth's doomsday will never materialize.

Worse, it seems that the climate flipped from one condition to another very rapidly. "It apparently took very little time, perhaps less than a decade or two, to shift between the states," Dr. J. C. W. White of the Institute of Arctic and Alpine Research at the University of Colorado wrote earlier this year in the scientific journal, Nature: "We humans have built a remarkable socio-economic system during perhaps the only time when it could be built, when the climate was stable enough to let us develop the agricultural infrastructure(基础设施) required to maintain an advanced society."
We do not know why we have been so blessed. But if the Earth had an operating manual, the chapter on climate might begin with a warning that the system has been adjusted at the factory for optimum comfort—so don't touch the dials.
Unfortunately, we have been "twiddling the knobs(旋钮)" for decades. In December 1995 the official Intergovernmental Panel on Climatic Change(IPCC), which represents the work of 2,000 top meteorologists from around the world, concluded that global warming due to human activities is probably already taking place. Global warming sounds deceptively favorable to inhabitants of countries which currently experience harsh winters. In fact, with global warming, the world would struggle to cope with the effects of even a steady, gradual warming. This was spelt out to members of the British Royal Society by Sir John Houghton, chairman both of Britain's Royal Commission of Environmental Pollution and of one of the main IPCC working groups. Houghton put forward the IPCC picture of seas flooding much of Egypt, southern China and Bangladesh, making "many millions" of people homeless; of hordes of "environmental refugees" and of wars breaking out over dwindling(becoming gradually smaller) fresh water supplies, as world rainfall patterns changed.
There is at least a chance that the world could adapt to steady warming if it happened slowly enough. However, many scientists, believe that even this prediction from the IPCC is too cautious.
Which of the following is NOT true according to the passage？
A．The climate in recorded human history has generally remained stable.
B．The climate from about 135,000 to 115,000 years ago was in a extremely cold state.
C．The human race has been lucky to have enjoyed the most favorable period of climate for them to build a socio-economic system.
D．The evidences scientists collected from the ice cores suggest that a civilization can not have arisen in the period from about 135,000 to 115,000.
