These are objectively true statements that most people have come to accept.

Key Points: 
  • These are objectively true statements that most people have come to accept.
  • But it is also true that Earth’s climate has never been stagnant and climate anomalies have been frequent throughout the past.
  • Are the impacts of modern climate change comparable to those of the medieval warm period (MWP) or the little ice age (LIA)?

Ecosystem background

    • Predators at the top of the food chain, like polar bears, reflect changes across the entire ecosystem, all the way down to microscopic algae.
    • In the Arctic, the base of the food web is sourced from two categories: sea ice-associated algae and open-water phytoplankton, which are distinguishable through their carbon isotopes.

Results from our study

    • In our study we examined stable carbon and nitrogen isotopes in polar bear bone collagen.
    • The polar bears were all from the Lancaster Sound sub-population and spanned the last 4,000 years.

What it all means

    • The results of the nitrogen isotopes showed that throughout time, 4,000 years BP to the present, the structure of the Lancaster Sound food web was relatively unchanged.
    • Polar bears eat seals, seals eat cod, cod eat zooplankton, et cetera.
    • There were no surprising shifts in the diets of polar bears despite past and present climate change.

Evidence of a warming climate

    • For ringed seals, the primary prey of polar bears, it is a platform for denning and raising young.
    • In this case, we have illustrated the magnitude of difference occurring in the modern Arctic, relative to past climate anomalies.
    • We can, therefore, not dismiss calls to action on climate change on the basis that the climate has always fluctuated.

One very large MPA, the Tallurutiup Imanga proposed National Marine Conservation Area covering 1.9% of Canadas ocean, is only proposed and so was not scored.

Key Points: 
  • One very large MPA, the Tallurutiup Imanga proposed National Marine Conservation Area covering 1.9% of Canadas ocean, is only proposed and so was not scored.
  • The results were driven by two very large and weakly protected MPAs, the Scott Islands marine National Wildlife Area in B.C.
  • The CPAWS report focuses on 18 federally designated MPAs that cover about 8.3% of Canadas ocean.
  • CPAWS is the first organization to assess Canadas federal MPAs against both The MPA Guide and the minimum protection standards.

It pulled together an unprecedented breadth and depth of ecological information into one resource to support Arctic marine planning.

Key Points: 
  • It pulled together an unprecedented breadth and depth of ecological information into one resource to support Arctic marine planning.
  • With the Arctic warming three times as quickly as the rest of the planet, urgent action is needed to protect the regions wildlife, which are increasingly under threat.
  • To date, the Canadian government has protected 13.8 per cent of its marine areas, including Tuvaijuittuq Marine Protected Area and Tallurutiup Imanga National Marine Conservation Area in the Arctic.
  • CanPAC brought together data/information about more than 500 features of Arctic marine ecosystems (for example, key habitats, nesting areas, etc.)

We want to express our deep condolences to all the victims\xe2\x80\x99 families, friends and colleagues during this incredibly difficult time.\nThe crash, which occurred as part of a trip to survey the Lancaster Sound polar bear population in Tallurutiup Imanga, is a devastating loss for the close-knit Arctic research community.

Key Points: 
  • We want to express our deep condolences to all the victims\xe2\x80\x99 families, friends and colleagues during this incredibly difficult time.\nThe crash, which occurred as part of a trip to survey the Lancaster Sound polar bear population in Tallurutiup Imanga, is a devastating loss for the close-knit Arctic research community.
  • One of the victims, Markus Dyck, who worked for the Nunavut government for 10 years as the Department of Environment\xe2\x80\x99s senior polar bear biologist, was one of the foremost polar bear experts in the country.\nOver the years, his research monitoring polar bears in Nunavut was supported in part by WWF-Canada's Arctic Species Conservation Fund.
  • Markus was a longtime WWF collaborator, a friend to many on our staff and we considered him an extended part of our WWF-Canada family.\n\xe2\x80\x9cI always admired his calm, cool and collected approach to the sometimes-charged issue of polar bear conservation.
  • When Markus spoke, everyone listened, and I can recall many meetings where he was the voice of reason.\n\xe2\x80\x9cAn incredibly dedicated researcher, Markus\xe2\x80\x99 contributions to polar bear management in Nunavut, and Canada as a whole, have been immense, and we all owe him a true debt of gratitude.

Meaning the ice never melts in Inuktitut, its a globally important area in the Canadian High Arctic almost the size of Germany.

Key Points: 
  • Meaning the ice never melts in Inuktitut, its a globally important area in the Canadian High Arctic almost the size of Germany.
  • The Qikiqtani Inuit Association, working with the governments of Canada and Nunavut, has led the charge to make Tuvaijuittuq a 322,000 sq.
  • km interim Marine Protected Area with an impact benefit agreement that delivers on their promise of a conservation economy to ensure communities benefit culturally and economically.
  • But to truly protect Arctic communities and species, Canada and the world must address thecause ofour climate crisis too much carbon in theatmosphere.
