This article shows CO2 emission profiles from oil, analyses how regional peak oil events shape emission curves and calculates that an annual 6% oil decline rate after 2012 would be needed to satisfy the boundary condition to keep global warming to 2 degrees C, with a 25% probability of exceeding this target.
Climate Institute: “We’re heading towards two to three and four degrees warming and if you think the weather extremes have been dangerous and unsafe, then you ain’t seen nothing yet.” http://www.abc.net.au/news/2013-05-11/carbon-pollution-reaches-highest-point-in-3-million-years/4680276
The collapse of the Soviet Union in the 90s resulted in an emissions reduction of 30% within a short time of 5 years, followed by a stabilisation.
Russia rescued the world from a deep oil crisis during a rebound in oil production starting in 2000, resulting in crude exports increasing by up to 2.5 mb/d. The total incremental amount of Russian exports between 2000 and 2010 was 8 times higher than what Saudi Arabia achieved.
