NAS on National Climate Assessment: ‘Without any estimates of uncertainty, its doubtful whether any policy maker could use this information’

“An example of how the report misses an opportunity to be informative. It gives a huge range of possible rises in sea level, using words like ‘reasonable’ and ‘useful.'” Continue reading NAS on National Climate Assessment: ‘Without any estimates of uncertainty, its doubtful whether any policy maker could use this information’

NAS on National Climate Assessment: ‘By overemphasizing the role of climate change, the report may encourage one-sided solutions’

“Multiple stressors are critical, but by taking such a climate-centric perspective, the report distorts the reality of these complex stressors and inadvertently sets up a perspective that reducing emissions will “solve” these problems.” Continue reading NAS on National Climate Assessment: ‘By overemphasizing the role of climate change, the report may encourage one-sided solutions’

NAS on National Climate Assessment: ‘The report is amazingly optimistic about the quality of the regional-scale projections’

“The present CMIP process shows that the variability between the models within a scenario is as large as the variations between scenarios. When you go beyond temperature into variables such as precipitation, the models diverge even more and that they cannot replicate the observational record on a regional scale.” Continue reading NAS on National Climate Assessment: ‘The report is amazingly optimistic about the quality of the regional-scale projections’

National Research Council review of National Climate Assessment: Report is ‘myopic’; ‘Models not especially good’; ‘Need honest assessment’
