Should we start with your original BS statement that Lloyds is no longer insuring commercial buildings in Canada due to hurricanes, forest fires and flooding or should we jump right into climate change?
If we are going to start with climate change I need to clarify my position. The climate is changing, it always has and always will. However I have not been able to find any credible evidence that the cause of the current change is man.
I am open to changing my mind but everything I have been able to dig up over the years leans heavily towards my position.
Evidence showing no trend in increased floods due to climate change.
A study from the Journal of Hydrology, Sept 2017
Climate-driven variability in the occurrence of major floods across North America and Europe
"In the current study, trends in major-flood occurrence from 1961 to 2010 and from 1931 to 2010 were assessed using a very large dataset (>1200 gauges) of diverse catchments from North America and Europe; only minimally altered catchments were used, to focus on climate-driven changes rather than changes due to catchment alterations."
"Overall, the number of significant trends in major-flood occurrence across North America and Europe was approximately the number expected due to chance alone. Changes over time in the occurrence of major floods were dominated by multidecadal variability rather than by long-term trends. There were more than three times as many significant relationships between major-flood occurrence and the Atlantic Multidecadal Oscillation than significant long-term trends."
Long term trends = climate change
Atlantic Multidecadal Oscillation = the 65 to 70 yr cycle in the change of the sea surface temperature of the north Atlantic with a 0.4C range between extremes.
