Here’s another lecture by a warmer.

It has been five years since Canada’s leading ice expert announced that multi-year ice is a thing of the past.

The multiyear ice covering the Arctic Ocean has effectively vanished, a startling development that will make it easier to open up polar shipping routes, an Arctic expert said on Thursday.

Vast sheets of impenetrable multiyear ice, which can reach up to 80 meters (260 feet) thick, have for centuries blocked the path of ships seeking a quick short cut through the fabled Northwest Passage from the Atlantic to the Pacific. They also ruled out the idea of sailing across the top of the world.

But David Barber, Canada’s Research Chair in Arctic System Science at the University of Manitoba, said the ice was melting at an extraordinarily fast rate.

NSIDC shows Greenland melting out of control, far above average this summer.

Greenland Ice Sheet Today | Surface Melt Data presented by NSIDC

This makes no sense, because NCEP maps have showed Greenland temperatures well below normal this summer.

Now lets look at the DMI graph of the same thing. DMI shows Greenland melting well below normal this summer.

Greenland Ice Sheet Surface Mass Budget: DMI

How did Mark Serreze’s NSIDC team pull off their Greenland nature trick?  They included the cold 1980’s in their average, which was the coldest decade on record in that region.

There was essentially no melting that decade, which dragged the mean line way down. More evidence of why DMI is a better reference than NSIDC. DMI doesn’t have a global warming agenda. The NSIDC graph is extremely misleading, no doubt by design.

Mark Serreze calls me “breathtakingly ignorant.”

The red circle shows the year when NSIDC starts their Arctic sea ice graphs. The mother of all cherry picks.

This proof is so simple, that even a climate scientist couldn’t understand it.

Sea level at Manhattan has been rising at a steady rate since the start of records in the 1850’s. The rate of rise has not accelerated or decelerated over the past 160 years.

The hockey stick doesn’t start until 1910, yet the sea level rise rate was essentially identical before and after the hockey stick. This tells us that there is no correlation between GISS temperatures and sea level. One station is adequate for this analysis, because melting glaciers would raise sea level more or less equally at all locations.

The graph below plots Manhattan sea level rise rates (9 year slope) vs. GISS  5 year mean global temperature anomaly. Again, there is no correlation between sea level rise rates and GISS temperatures. The fastest decline in sea level occurred near the highest temperature anomaly.
