Global
Warming: Polar Bears
Scientists
warn us that global warming may cause all kinds of devastating
effects on this planet. Researchers
expect that global warming will cause the weather to change,
including an increased number of natural disasters, increased
global temperature, and the loss of many animal species. Scientists
have pointed to the polar bear as one of the most threatened
species.
According
to recent research done by the Canadian wildlife service, polar
bears are poised to suffer from irrevocable damage sooner
than almost any other species. The most
current research indicates that polar bears are being threatened
with
the threat of starvation as their hunting season becomes reduced
gradually by the effects of climate change. According to the
most recent research put forth by the Canadian wildlife service,
polar bears studied along the Western Hudson Bay in Canada
has also shown that the shortened hunting season is causing
many hungry polar bears to wander into areas of Canada that
had previously not been visited by polar bears.
The wandering polar bears are now causing a problem with local
authorities, who have had to use everything from cracker shells
to security dogs and vehicles to keep bears away from human
property. The latest Canadian research has found that the main
source of food for the polar bears have traditionally been
ringed seals. However, ringed seal populations are dwindling
and becoming much less accessible to the local polar bear populations.
This is because the ice around Hudson Bay is breaking up thanks
to the effects of global climate change, causing the local
ring seal popular to dwindle. This, in turn, causes the polar
bear population to have less time to hunt.
The most recent research has also shown that polar
bear weight in both female and male polar bears has been declining in recent
years. Research has also shown a pattern in which polar bear
females have been giving birth to fewer cubs. Even though it
all sounds very grim, researchers have been quick to point
out that there is not yet any strong evidence of popular decline
in the local polar bear populations. However, researchers fear
that is the current cycle continues, the polar bear population
will be one of the first to go into serious decline.
There is now definite evidence that in the Hudson Bay area
the sea season has been shortened. It appears that global climate
change is responsible for the shortened sea season that has
been measured in recent years, and appears to fit in an overall
pattern of global warming. The most recent research shows that
the overall sea season in the Hudson Bay area of Canada has
been cut down by about 20 years.
The polar bear population of the Hudson Bay area in Canada
is being closely watched and studied by researchers, and it
appears that this closely watched population will tell us much
about what we need to know about how climate change is affecting
to worldwide polar bear populations. In one of the most cited
NASA studies, it was determined that there has been
an almost three percent decline in the total sea ice in the
Arctic area. This means that the polar bears in Hudson Bay are only symbolic
of a much larger worldwide problem caused by the devastating
effects of global climate change.
The only way to help recover from the devastating effects
of global climate change is to cut greenhouse gases immediately.
This is what the research indicates and what needs to be done
if we want to save the life on Earth as we know it. After all,
we can already track how polar bears are being affected, and
it may not be much longer until we can track the change in
human populations.
