“…In the U.S.A., maximal crude-oil production 2010 2030 Aleklett [15] 2011 2015-2020 Murphy [16] 2011 2035 Winch [17] The wide use of crude oil, and of fossil fuels in general, has also given rise to a separate, but equally pressing concern: that the liberation of carbon dioxide to the atmosphere attendant on the use of these fuels is having a major, and potentially accelerating, deleterious climate effect, which may impinge in critical ways on the world economy and the well-being of mankind. The two considerations are independently important: even if easily accessible, vast new oilfields were to be found in the near future, relieving the supply concerns in this area, the continuous increase in atmospheric CO2 over the past decades is deemed to be of sufficient concern to warrant worldwide, concerted efforts to reduce production of this gas, mainly by switching energy production on a large scale to new, alternative forms, which minimize or entirely avoid the formation of this by-product.…”
