The largest of the great lakes in the United States, Lake Superior
Lake Superior’s ice coverage has greatly surpassed expectations this year.
Earlier in the season, forecasters predicted the lake would reach a little more than 50 percent ice coverage this winter. But as of Friday, Lake Superior was over 85 percent covered, far exceeding the prediction and the lake’s long-term average of 55 percent, according to the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Laboratory, or GLERL.
This year’s frigid conditions triggered the rapid expansion of the ice that exceeded predictions, said Jia Wang, a research ice climatologist and physical oceanographer at GLERL.
[...] Earlier this week, ice coverage increased about 10 percent within 12 hours, rising from around 75 percent at 2 p.m. Wednesday to nearly 85 percent by 2 a.m. Thursday.
[...] The last time the lake ice reached 100 percent coverage was 1996, which is the only time 100 percent coverage on Lake Superior has been noted since records started in 1973, according to GLERL data.

I don't think you even looked at the simpson's paragraph page, it is all due to varying sample sizes.

Blame autocorrect: paragraph -> paradox

The original assertion that all regions of the world can have cooling trends while the global temperature is warming is still wrong. The example given in the article was of grouping observations along the same parameter that the trends were determined along. That introduces observation bias. That bias doesn't exist when one groups temperature readings by spatial region and looks at temperatures in time. One no longer has the conditions leading to the spurious trend creation.
