Past Tipping PointThe plan is too little, too late – they can’t stop warming now Ghommem, Hajj, and Puri 12 (Mehdi Ghommem, Muhammad R. Hajj, Ishwar K. Puri, Department of Engineering Science and Mechanics, Virginia Tech, 4/26/12, “Influence of natural and anthropogenic carbon dioxide sequestration on global warming” Ecological Modelling, SciVerse Science Direct) We have used the results of previous GCM simulations to develop a model that accounts for the couplings between the global temperature, atmospheric CO2 concentration, and the ocean and land CO2 uptakes. The good agreement between the results of the simplified model and historical records for both atmospheric CO2 and global temperature demonstrates that our reduced order analysis is able to correctly reproduce the major CO2 feedbacks between natural sinks and the atmosphere. We have also used the model to investigate the impact of anthropogenic CO2 sequestration on the increase in the global temperature. Our results suggest that an inordinately large, and perhaps unrealizable, fraction of CO2 emissions would have to be sequestered in order to prevent global warming. Undoubtedly, without referring to the environmental consequences, sequestration could be used as one among several carbon mitigation strategies to accomplish large effective μ values. Warming is real but the plan can’t solve it Ghommem, Hajj, and Puri 12 (Mehdi Ghommem, Muhammad R. Hajj, Ishwar K. Puri, Department of Engineering Science and Mechanics, Virginia Tech, 4/26/12, “Influence of natural and anthropogenic carbon dioxide sequestration on global warming” Ecological Modelling, SciVerse Science Direct) The increase in the global surface temperature is influenced by several factors including anthropogenic and natural emissions of CO2, and the ability of natural sequestration reservoirs in the Earth's oceans and land to absorb and store it. The CO2 absorption in these reservoirs is sensitive to changes in the global temperature and the atmospheric CO2 concentration, thus creating a feedback loop in the Earth's ecosystem, which complicates predictions of the overall impact of rising atmospheric CO2 levels on global warming. Here, we model this interaction through a positive feedback loop and utilize general circulation models (GCM) to quantify the coupling between the carbon-cycle and the global temperature. We validate the model by comparing its predictions with those from high fidelity simulations and historical records. Thereafter, we investigate the impact of anthropogenic CO2 sequestration on lowering the rate of increase in the global temperature and find that a reduction in global warming is more sensitive to larger sequestration fractions. Thus, an inordinately large fraction of CO2 emissions would have to be sequestered to significantly impact global warming. Soon…Runaway warming leads to extinction – timeframe is 2020 Stein 7/18/12 — (David Stein, Science Editor for The Canadian, news agency, “Scientists say Humanity ignores Antarctic melting and Greenhouse gas time-bombs with the price of Mass-Extinction,” http://www.agoracosmopolitan.com/home/Frontpage/2007/02/26/01381.html) Global Warming continues to be approached by governments as a "luxury" item, rather than a matter of basic human survival. Humanity is being taken to its destruction by a greed-driven elite. These elites, which include 'Big Oil' and other related interests, are intoxicated by "the high" of pursuing ego-driven power, in a comparable manner to drug addicts who pursue an elusive "high", irrespective of the threat of pursuing that "high" poses to their own basic survival, and the security of others. Global Warming and the pre-emptive war against Iraq are part of the same self-destructive prism of a political-military-industrial complex, which is on a path of mass planetary destruction, backed by techniques of mass-deception. "The scientific debate about human induced global warming is over but policy makers - let alone the happily shopping general public - still seem to not understand the scope of the impending tragedy. Global warming isn't just warmer temperatures, heat waves, melting ice and threatened polar bears. Scientific understanding increasingly points to runaway global warming leading to human extinction", reported Bill Henderson in CrossCurrents. If strict global environmental security measures are not immediately put in place to keep further emissions of greenhouse gases out of the atmosphere we are looking at the death of billions, the end of civilization as we know it and in all probability the end of humankind's several million year old existence, along with the extinction of most flora and fauna beloved to man in the world we share. The Stephen Harper minority government backed by Alberta "Big Oil", the U.S. Republican President Bush administration, and a confederacy of other elites associated with a neo-conservative oriented political-military-industrial complex, has only sought to "buy time" against his critics, (and mount a disingenuous public relations campaign under a new Minister of the Environment). It is apparent that The Stephen Harper government has no commitment to providing any leadership on Canadian or global achievement of the minimum standards set on greenhouse gas emissions reductions under the Kyoto Protocol. The immediate threat of runaway global warming and climate change melt-down There are 'carbon bombs': carbon in soils, carbon in warming temperate and boreal forests and in a drought struck Amazon, methane in Arctic peat bogs and in methane hydrates melting in warming ocean waters. "For several decades it has been hypothesized that rising temperatures from increased greenhouse gases in the atmosphere due to burning fossil fuels could be releasing some of and eventually all of these stored carbon stocks to add substantially more potent greenhouse gases to the atmosphere," Bill Henderson further elaborates. Given time lags of 30-50 years, we might have already put enough extra greenhouse gases into the atmosphere to have crossed a threshold to these bombs exploding, their released greenhouse gases leading to ever accelerating global warming with future global temperatures maybe tens of degrees higher than our norms of human habitation and therefore extinction or very near extinction of humanity. "(T)he science is clear. We need not a 20% cut by 2020; not a 60% cut by 2050, but a 90% cut by 2030 (1). Only then do we stand a good chance of keeping carbon concentrations in the atmosphere below 430 parts per million, which means that only then do we stand a good chance of preventing some of the threatened positive feedbacks. If we let it get beyond that point there is nothing we can do. The biosphere takes over as the primary source of carbon. It is out of our hands," George Monbiot says.
