TIP # 14:
Previous to feeding, the diet should be
warmed to just
below body temperature.
If you look at the Fig. 3a in our review (red lines at the top) you see that many
previous estimates based on the observed
warming / ocean heat uptake had a tendency to peak at values
below 3 °C (that review is from 2008).
For more on the terrestrial foods topic, see my detailed discussion in this
previous post, and this recent (March 30) ScienceNews report on yet another, largely anecdotal «polar bears resort to bird eggs because of declining sea ice» story (see photo
below, based on a new paper by Prop and colleagues), which was also covered March 31 at the DailyMail («Polar bears are forced to raid seabird nests as Arctic sea ice melts — eating more than 200 eggs in two hours,» with lots of hand - wringing and sea ice hype but little mention of the fact that there are many more bears now than there were in the early 1970s around Svalbard or that the variable, cyclical, AMO (not global
warming) has had the largest impact on sea ice conditions in the Barents Sea).
This is an improvement over
previous trends, which would lead to 4 - 5 °C of
warming, but falls short of the global goal to limit
warming to
below 2 °C (3.6 °F).
Notice that there are 2 outlier years — 2007 and 2012 — that fall
below the
previous cluster of low sea ice years during the 1930s, when the Arctic was just as
warm as it is today.
The Eemian period (the
previous one ~ 100k yrs ago) was a couple of degrees
warmer, sea levels were a few metres higher, but CO2 levels were still
below 300 ppmv.
