His main argument was that the aerosol forcing is too uncertain to allow the Shindell method to tightly constrain climate sensitivity. (skepticalscience.com)
The differences among proxy reconstructions are still an obstacle when attempting to constrain climate sensitivity more tightly solely on the basis of LGM climate. (dotearth.blogs.nytimes.com)
Considering that we have just seen another study (Skeie) showing that using more recent data constrains climate sensitivity, can Dr. Forest justify ignoring the 16 years of additional observational data? (judithcurry.com)
