This is both my personal learning project and my contribution in the struggle to confront the ongoing Republican/ libertarian assault on rational science and constructive learning, as manifested in their malicious strategic Attacks on Science ~ A collection of articles, scientific resources, plus my own essays and indepth critique of various presentations from unidirectional-skeptics ~ Hopefully a resource for the busy, yet discerning, student who's concerned about the health of our Earth
Lately I haven't had much time for this, but Mr. Steele smacked me with another one yesterday. After reading his SKEP thread reprinted below and his full article and looking up some stuff I started a response but it's such a gish gallop with the guy, then I got all caught up in an aside now I've run out of time. So I'll just post it over here. Let him know I'm doing my homework and I'll be back.
Not only did warming alarmist amputate data that showed improving polar bear condition, in a dubiously named 2012 article " Effects of climate warming on polar bears: a review of the evidence" they amputated data that reported it is actually heavy ice years that are the worse for seals and bears.
Polar bear experts Ian Stirling and Andrew Derocher{check out the links I added} (who predicts by the middle of this century, two-thirds of the polar bears will be gone due to rising CO2) published in a section titled, “Why progressively earlier breakup of the sea ice negatively affects persistence of polar bearsubpopulations" to illustrate the importance of ringed seal pups they wrote, “In the mid-1970s and again in the mid-1980s, ringed seal pup productivity plummeted by 80% or more for 2–3 years…. A comparison of the age-specific weights of both male and female polar bears from 1971 to 1973 (productive seal years), to those from 1974 to 1975 (years of seal reproductive failure), demonstrated a significant decline in the latter period.”
They referenced those years of bad seal and bad bears in Stirling’s 2002 paper. But if you actually read that paper Stirling contradicted his own “review of the evidence” writing, “Heavy ice conditions in the mid-1970s and mid-1980s caused significant declines in productivity of ringed seals, each of which lasted about 3 years and caused similar declines in the natality of polar bears and survival of subadults, after which reproductive success and survival of both species increased again.” In 2012, Stirling coauthored another paper with a seal researcher and concluded all declines were caused by heavy ice years. Their paper proposed that “the decline of ringed seal reproductive parameters and pup survival in the 1990s could have been triggered by unusually cold winters and heavy ice conditions that prevailed in Hudson Bay in the early 1990s, through nutritional stress”

Here we have a favorite tactic.
Think about what's going on here, Steele is reaching back to the seventies, eighty when conditions had been relatively stable, and had been for millennia (even considering the LIA/MWP).
