Conservation status of polar bears (Ursus maritimus) in relation to projected sea-ice declines. It is true that in 2007, it was predicted that polar bear numbers would plummet when summer sea ice declined to 42% of 1979 levels for 8 out of 10 years (anticipated to occur by 2050) and extinct or nearly so by 2100 (Amstrup et al. ‘Why are polar bears going extinct?’ contains a false premise – there is no need to ask ‘why’ when the ‘polar bears [are] going extinct’ part is not true.1.

Google says many people ask this question so here is the correct answer: polar bears are not going extinct. UPHEAVAL – my new ice tsunami novel – is now available! New Zealand just Declared a Climate Emergency, New Paleoclimatology Finding Shows Earth's Climate Was Typically Warmer than Today, Roger Pielke Jr.'s 2020 Hurricane Season Recap, Climategate: Another Anniversary (never forget ….

This is the result of a new study by the WWF and the Norwegian Polar Institute (NPI). Seriously, what is wrong with you people. Reposted from Dr. Susan Crockford’s Polar Bear Science. Posted on July 25, 2020 | . The slow but steady melting of the ice can be traced on 6,000 maps. The graph below was constructed by NASA sea ice expert Walt Meier and published by the US National Snow and Ice Data Center in early October 2019. within the last 10,000 years. Before that, I used the name Karl J. Hansen in order to stay employed. The 86 multiplier is the Global Warming Potential GWP that can be found in all five IPCC reports although over time the GWP increases along with the increase in the concentration of atmospheric CO2. German source. Great work by Dr Susan Crockford, “2. As I said above, âWhy are polar bears going extinct?â contains a false premise â there is no need to ask âwhyâ, when the âpolar bears [are] going extinctâ part is not true.

According to Ms. Crockford’s last graph, from 1994 through 2014 the polar bear population was roughly stable at about 22,000 to 25,000 bears, while the minimum September sea ice was decreasing. Your second statement is the real point. Wiig, Ã., Amstrup, S., Atwood, T., Laidre, K., Lunn, N., Obbard, M., et al. Global Warming Policy Foundation, London. The most recent information available is summarized in the upcoming State of the Polar Bear Report 2019, to be released 27 February 2020 but see also the 2018 report (Crockford 2019b). Why would they do so now even if the arctic does go ice free in the summer. So far, the response of polar bears to recent ice loss suggests that they will continue to thrive with even less summer ice than there has been in recent years as long as ice in winter (December-March) and spring (April-June) remains reasonably abundant, as has been the case to date. It applies, by the way, to 10% of the animals on land. Reposted from Dr. Susan Crockford’s Polar Bear Science.

BTW, in the last polarbear thread someone asked, what happend to the 2012 Arctic temperatures. Researchers found that even if methane is released from these natural stores in response to warming, very little reaches the atmosphere; therefore, anthropogenic emissions should be more concerning than these natural feedbacks. Neither do the Inuit, who live there. P olar bears are likely to go extinct before the end of the 21 st century. Amstrup, S.C., Marcot, B.G. Global Warming Policy Foundation, London. So far, the response of polar bears to recent ice loss suggests that they will continue to thrive with even less summer ice than there has been in recent years as long as ice in winter (December-March) and spring (April-June) remains reasonably abundant, as has been the case to date. 2007; Crockford 2017, 2019). It’s rather obvious that an increase of .182 ppm would increase temperature by nearly nothing, and 86 times nearly nothing is still nearly nothing. See the supplement for population figures here.
