The data don't themselves prove what led to such a
dramatic decrease in emissions, but Schaefer's team had a guess: the collapse of fossil fuel
production in the Soviet Union following its 1991 breakup.
And the
dramatic decrease in the costs of genome sequencing, spurred on by the Human Genome Project, makes
production of this data a bargain by any estimate.»
Its print output for 2013 was projected at 1,108,183 titles, a
decrease of 46 percent from its
production of 2,042,840 titles
in 2012 and a
dramatic reverse from its 55 percent growth
in 2012 over 2011.
I start (and started) from the premise that the
dramatic decline
in crude oil prices that took place from August, 2014 ($ 96 / barrel), to March, 2015 ($ 44 / barrel), was due — on the one hand — to
decreased demand, a function of slow economic growth
in Asia, Europe, and elsewhere, endogenous, price - driven technological change leading to greater fuel efficiency, and policy - driven technological change that also has been leading to greater fuel efficiency, such as more stringent Corporate Average Fuel Economy (CAFE) standards
in the United States; and — on the other hand — was due to increased supply, partly a function of the growth of unconventional (tight) U.S. oil
production (a product of the combination of two technologies — horizontal drilling and hydraulic fracturing).
