And while we can’t say that Hurricane Sandy was literally caused by climate change, we know with some degree of confidence, that the impacts where made worse by climate change. For example, that 13-foot surge that flooded a large part of Manhattan, at least one of those 13 feet was due to human caused global warming.
The tide gauge measurement of sea level at Lower Manhattan has been increasing linearly for over 150 years, with the peak slope around 1940. There isn’t one shred of evidence that CO2 emissions have affected sea level in New York, much less raised sea level by one foot. His claim has zero scientific basis.
