Andrew Weaver, the head of the British Columbia Green Party and lead IPCC author, predicts sixteen feet of sea level rise.
There has been no change in sea level at British Columbia over the past century. Sea level there is currently near a record low. It will require ~∞ years to produce five meters of sea level rise at British Columbia..
Globally, according to NOAA, sea level is rising less than two millimeters per year. It will require more than 2,500 years to achieve five meters of sea level rise.
the absolute global sea level rise is believed to be 1.7-1.8 millimeters/year
Weaver bases his claim of five meters of sea level rise on “collapse of the West Antarctic Ice Sheet” due to “carbon emissions” – but scientists have known for 40 years that the behavior of the West Antarctic Ice Sheet has nothing to do with climate.
The Ross Ice Shelf in West Antarctica has been retreating for centuries, and had retreated 30 miles by 1930. The retreat has nothing to do with CO2.
Satellites show no trend in Antarctic temperatures over the past 40 years.
NASA’s head of climate analysis reported in 2004 that Antarctica was cooling rapidly.
during recent decades, surface temperatures decreased significantly over most of Antarctica.
Two years ago, NASA reported that Antarctica is gaining ice, and has been for the past 10,000 years.
Tide gauges show no indication that sea level rise is accelerating, and there is no indication that CO2 emissions have any impact on sea level. Sea level rise rates track sunspot cycles, not CO2.
Andrew Weaver’s claim of five meters of sea level rise due to CO2 emissions is absurd, and far outside the range of IPCC estimates, of which he is a lead author.
For high emissions IPCC now predicts a global rise by 52-98 cm by the year 2100
The 1990 IPCC Report said there was no convincing evidence sea level rise accelerated during the 20th century.
9.3.3 Accelerations in Sea Level Rise
Is there evidence of any “accelerations” (or departures from long-term linear trends) in the rate of sea level rise? From examinations of both composite regional and global curves and individual tide gauge records, there is no convincing evidence of an acceleration in global sea level rise during the twentieth century. For longer periods, however, there is weak evidence for an acceleration over the last 2-3 centuries
Nothing about Weaver’s sea level claim appears credible. Andrew Weaver is suing Canadian climate expert for Tim Ball for defamation, and I am an expert witness for the defense. Weaver’s lawyers chose not to cross examine me.
I wonder why not?
