Sentences with phrase «given change in the greenhouse gas concentration»

Almost all the SOD's 10.2 % error standard deviation for greenhouse gas AF relates to the AF magnitude that a given change in the greenhouse gas concentration produces, not to uncertainty as to the change in concentration.

Not exact matches

Biello: A lot of scientists that I've spoken to think we have no chance of meeting 450 ppm given that we haven't done hardly anything to change our course and there are other scientists who say that we have already well past kind of the safe point for concentration of the greenhouse gases in the atmosphere.

Climate change scenarios are based on projections of future greenhouse gas (particularly carbon dioxide) emissions and resulting atmospheric concentrations given various plausible but imagined combinations of how governments, societies, economies, and technologies will change in the future.

If we knew ocean heat uptake as well as we know atmospheric temperature change, then we could pin down fairly well the radiative imbalance at the top of the atmosphere, which would give us a fair indication of how much warming is «in the pipeline» given current greenhouse gas concentrations.

Paul Voosen, one of the most talented journalists probing human - driven climate change and related energy issues, has written an award - worthy two - part report for Greenwire on one of the most enduring sources of uncertainty in climate science — how the complicated response of clouds in a warming world limits understanding of how hot it could get from a given rise in greenhouse gas concentrations:

For instance, US Senator James Imhofe of Kansas called climate change «the greatest hoax ever» (Johnson, 2011) To claim that climate change science is the greatest hoax ever is at minimum, if not a lie, reckless disregard for the truth given the number of prestigious scientific organizations that have publicly supported the consensus view, the undeniable science supporting the conclusion that if greenhouse gases increase in the atmosphere some warming should be expected, the clear link between rising greenhouse gas concentrations in the atmosphere and increases in fossil fuel use around the world, as well undeniable increases in warming being that have been experienced at the global scale.

The presence of feedback effects and tipping points calls into question some of the most fundamental assumptions of climate change negotiations, including the belief that we can «overshoot» to, say, 550 ppm and then work back to 450 ppm (the path advocated in the Stern and Garnaut reports), that greenhouse gas concentrations in the atmosphere can be stabilised at some level, and the belief that we can adapt to some given degree of warming.

Given the growing urgency of the need to rapidly reduce global greenhouse gas emissions and the hard - to - imagine magnitude of global emissions reductions needed to stabilize atmospheric concentrations at reasonably safe levels, the failure of many engaged in climate change controversies to see the practical significance of understanding climate change as an ethical problem must be seen as a huge human tragedy.
