NASA’s James Hansen gets dissed by global warming establishment! Warmists Say Sea Level Rise study based on ‘flimsy evidence’ & ‘rife with speculation’

Former Top NASA Scientist James Hansen Predicts Catastrophic Rise In Sea Levels – ‘Projects sea levels rising as much as 10 feet in the next 50 years.’ – The paper has already ruffled some, including Associated Press science writer Seth Borenstein, who said on Twitter that he would not cover it — primarily because it had not yet been peer-reviewed, a process that allows other scientists to critique the work. The Washington Post’s Chris Mooney asked other climate experts to weigh in on the paper. While many said it raised key discussion points, Kevin Trenberth of the National Center for Atmospheric Research called it “provocative and intriguing but rife with speculation and ‘what if’ scenarios.”

Warmist New claim: ‘Recent sea level rise is highest in 6,000 years’ — DEBUNKED

Latest warmist claim on sea level here.

Debunking here  – Also see: Claim: ‘No change in sea level until modern times – but that change is dwarfed by sea levels of the past‘

Rebuttal: Examination of the data from the paper, however, shows the range of proxy sea levels is approximately 10 meters, far too large to discern the tiny ~1.5 mm/yr sea level rise over the past 150 years. The authors instead assume from other published studies of tide gauge measurements that the ~1.5 mm/yr sea level rise over the past 150+ years began at that point in time. Other papers find sea levels rising only 1.1-1.3 mm/yr over the past 203 years, and without acceleration. 

Regardless, even the IPCC concedes that there was no significant anthropogenic influence on climate prior to 1950, thus man is not be responsible for sea level rise beginning 150-200 years ago, at the end of the Little Ice Age.

The sea level rise over the past ~200 years shows no evidence of acceleration, which is necessary to assume a man-made influence. Sea level rise instead decelerated over the 20th century, decelerated 31% since 2002 and decelerated 44% since 2004 to less than 7 inches per century. There is no evidence of an acceleration of sea level rise, and therefore no evidence of any man-made effect on sea levels. Sea level rise is primarily a local phenomenon related to land subsidence, not CO2 levels. Therefore, areas with groundwater depletion and land subsidence have much higher rates of relative sea level rise, but this has absolutely nothing to do with man-made CO2.

 – [Climate Depot Note: According to tide gauges, Sea Level is rising LESS than the thickness of one nickel (1.95 mm thick) per year or about the thickness of one penny (1.52 mm thick) a year. According to satellite info it is rising slightly more than two pennies a year (3.04 mm)]
