Climate Change and Polar Bears

This annotated bibliography discusses the impact of climate change on polar bears and their habitat selection. It includes studies on the effects of sea ice loss, population status, and the consequences of climate warming and pollutant exposure. The bibliography also highlights the need for conservation efforts and recommendations to mitigate the effects of climate change on polar bears.

loss." Proceedings of the Royal Society B: Biological Sciences 283.1836 (2016):

The author indicated that climate change is expected to alter the habitat of many
species. The primary objective was to study the change in habitat selection of polar bears,
before and after widespread sea ice changes. Result revealed that the habitat selection pattern
of polar bear has not changed significantly. However, if the preys alter their places in
summer, polar bears also prefer to change habitats.

and conservation recommendations for the 21st century." Conservation Biology29.3
(2015): 724-737.
The author in this article specified that the arctic marine mammals are more likely to
suffer from the effects of climate change as they have close association with sea ice. The
author suggested the reduction of emissions as the primary solution to mitigate global
warming or climate change. In the article the author also recommended effective co-
management, improved monitoring and some legislation to protect the species in this regard.

consequences of climate warming and pollutant exposure." Frontiers in Ecology and
Evolution 3 (2015): 16.
In this article, the author discussed that one of the main effects of climate change for
the polar bears is limited access to the preys due to the loss of their sea ice habitat. Review of

several literatures in the study clearly indicated that climate induced loss of sea ice negatively
affected polar bears in some sub-populations.
Regehr, Eric V., et al. "Conservation status of polar bears (Ursus maritimus) in relation
to projected sea-ice declines." Biology Letters 12.12 (2016): 20160556.
The article states that loss of arctic sea ice due to change in climate have become a
threat to the lives of the polar bears in arctic region. Polar bears highly depend on sea ice. The
study findings clearly indicated the large decline in the number of polar bears due to climate
change and loss of sea ice.

Shows." Latest Stories, 1 Feb. 2018, news.nationalgeographic.com/2018/02/polar-bears-

It is a video showing the change in the lives of polar bears along with the change in
climate. Polar bears depend on seals for food and the sea ice shrink by 14% per decade
according to the scientists due to which seals are changing their habitat and as a result polar
bears are nearly starving. Scientists suggested addressing climate change for the long-term
survival of the polar bears.
