Massive Growth In Arctic Ice This Year!

Arctic sea ice extent is up 16% from last year. 2017 2016 Greenland ice growth is close to last autumn’s record high. Greenland Ice Sheet Surface Mass Budget: DMI Meanwhile, criminals in the press and academia insist that the Arctic is “melting more rapidly than expected.” 97% of government funded climate science is not […]

October Arctic Ice is Back

Iowa Climate Science Education

Given the fluctuations in daily sea ice measurements, climatology typically relies on monthly averages. October daily extents are now fully reported and the 2017 October monthly results can be compared with years of the previous decade.  MASIE showed 2017 reached 6.8M km2, exceeding the 6.6M October 10 year average.  SII was close behind at 6.7M for the month.  The 11 year linear trend is more upward for MASIE, mainly due to early years, especially 2007 and 2008 reported higher in SII.  In either case, one can easily see the Arctic ice extents have not declined; MASIE shows 2017  higher than 2016 by 800k km2, and more than 2007 by 1M km2.

Sea Ice Index statistics are from newly released SIIv.3.0,  as reported in Sea Ice Index Updates to v.3.0.

The graph below shows October comparisons through day 304 (Oct. 31).

Note that 2017 in both MASIE and SII tracked the 10…

Churchill Polar Bears

Churchill, Manitoba’s Polar Bear Alert Program is still reporting many fewer problems with polar bears onshore than it did last year at the same point in the ice-free season (week 5, 7-13 August): Compare to week five last year (2016), when bears came ashore in excellent condition: Although it’s been warmer than average recently (25.4 […]

Sea Ice Off Newfoundland/Labrador Heaviest in Living Memory

Amid reports that ice conditions between Newfoundland and southern Labrador are the worst in living memory, another polar bear was reported ashore in the area — just after biologist Andrew Derocher explained to the CBC that bears only come on land when sea ice conditions “fail.” “Ice too thick for coast guard’s heavy icebreaker” said […]

Cross Breeding of Bears?

A new paper on the evolutionary history of bears (Bears breed across species borders: Kumar et al. 2017) has concluded that hybridization is common and natural among all species of ursids. And while some media outlets (e.g. DailyMail) have framed this as surprisingly convincing proof that experts were wrong to claim that climate change is […]
