Pressing the frontiers of climate science and related research is vital, but it's wishful thinking to expect further science to substantially narrow uncertainties on time scales that matter when it comes to regional or short - term climate forecasting, the range of possible warming from a big buildup of carbon dioxide, the impact of greenhouse forcing on rare extremes and the like.
Steven E. Koonin, once the Obama administration's undersecretary of energy for science and chief scientist at BP, stirred up a swirl of turbulence in global warming discourse this week after The Wall Street Journal published «Climate Science is Not Settled,» his essay calling for more frankness about areas of deep uncertainty in climate science, more research to narrow error ranges and more acknowledgement that society's decisions on energy and climate policy are based on values as much as data.
As already noted, my iRF efficacy uncertainty ranges are much narrower than Marvel et al.'s.
Without being able to properly narrow those ranges of uncertainty, CO2 has to be the problem.
So, recent research is narrowing the range of uncertainty of the aci, and overall reducing the magnitude of the aci effect.
Complexity of the climate system and uncertainty surrounding input data preclude extremely accurate predictions, but they are not incompatible with an ability to approximate real world outcomes within a range narrow enough to justify future planning on the basis of reasonable probabilities.
If you can't narrow it down because of the uncertainties, you supply a range from best case to worse case and let the pollies decide what is acceptable — that's their job, right?
The hope is that new research can help narrow the range of uncertainty.
In fairness, there remains considerable uncertainty in aerosol effects, but if there will be real progress in narrowing the credible range for climate sensitivity, it has to come from reducing the still too wide uncertainty in aerosol effects, not from flogging climate models which assume aerosol offsets inconsistent with the best available measured effects.
The outcome is relatively predictable, with a narrow range of uncertainty.
The problem seems to be that even during that time, the 2 - 4.5 C estimated range hasn't narrowed much, and so the same level of uncertainty prevails.
Thus the uncertainty in sensitivity itself argues for insurance against high sensitivity, and narrowing down the range (and particularly excluding the higher end) could significantly change our optimal policy response.»
While different researchers have different best estimates (James Annan, for example, says his best estimate is 2.5 C), uncertainties still mean that estimates can not be narrowed down to a far narrower and more precise range.
