The latest climate doom paper “Sea-level rise due to polar ice-sheet mass loss during past warm periods” uses inaccurate proxies of sea levels and temperatures of past periods to conclude that even without any further increase of temperatures we could have soon sea level rises of 6-9 metres. The paper ignores the evidence that the global temperatures are not warming over this century, as the global sea levels are nor significantly rising nor accelerating, and the Antarctic sea ice growth has ultimately outpaced the Arctic sea ice shrinking, while the carbon and hydrocarbon fuel usage has been further escalating, suggesting a decoupling between the three parameters and the carbon emission. In soccer, the intergovernmental players inadvertently strike the ball into their own team's goal. If with temperatures claimed as of today and about same carbon dioxide concentrations of 1890 the sea levels have been 6-9 metres higher 125,000 years ago, because parts of the Antarctic and the Greenland ice sheets have melted for other reasons than global warming, this does not mean we should try harder to change the climate by supporting not working renewable energies and paying carbon taxes. Preferably, we should do just nothing different from using our natural resources without feeling guilty for something it does not depends on us to achieve about same result. Sea levels may rise of up to 6-13 metres, or even fall, and even if the science of climate is settled we haven’t understood yet why.
