Migration Caused by Global Warming

Global warming has been affecting Earth for years now. Lately it has been causing
aquatic animals to migrate to other bodies of water than where they were originally from.  It is being caused by ice melting, climates, and ice clogging passage ways.  Animals like whales, oceanic fishes, and stream fish have all been affected.

 Bowhead whales are moving from opposites sides of the Canadian High  Artic to the Northwest Passage. It is normally clogged by ice which connects the Atlantic and Pacific Oceans. There have been other signs that the amount of these air-breathing animals’ traversed to the Artic when the ice cover shrinks. There are new satellite tracking data that track the whales and shows that they are in the Northwest Passage.

Climate in Southern California region are effecting the distribution of oceanic fishes. Scientist have discovered this by using larval fish data, which is one of the types of oceanic fishes moving, from years past. These species respond to environmental changes in the areas where they live. Eight of these species have moved a great amount from 1950-1998, because of different climates changes with temperature. With these climate changes it is having a great effect on the distribution, on the abundance of oceanic fishes, and where the live.

In the nine French river units there are many species of stream fish.  Stream fish are very affected by climate change, because they are exothermic fish. They are also affected by physical things that may stop them from moving to a new place. These species are deleterious effect on climate change where as the species that are down the stream just expand their living spaces.

In conclusion, animals have been moving to different places to survive, because of global warming.  All animals are being affected by this not just the ones that live on land but the ones in the water too. All in all no matter if they are the size of a whale or a fish it affects the tiniest species in the world.

How are humans also affecting this migrating problem?

How are the animals that are migrating, to new places, are affecting the other animals that already live there?

How do these animals migrating affect us humans?

  1. I was interested in your blog because it is somewhat similar to my topic. Mine is also about animals affected by human pollution. Human pollution’s affect on animals is a major cause for concern for the animals and the environment in which they live in. Polar Bear are some the most highly affected by this tragic and horrible pollution. Humans need to keep better track of the pollution they let off instead of just dumping it and forgetting about it. This is constantly getting combated by organizations like the EPA, The European Union, and Earth Charter Initiative. These people are constantly striving to help the animals and environment in which they live. If you want some more info on things like Polar bears this site is pretty good.>>>> http://www.polarbearsinternational.org/polar-bears/bear-essentials-polar-style

  2. Animals like polar bears and penguins live on ice their whole lives, so if their home is suddenly gone, they have no choice but to migrate. After many years, I would imagine there would be very little ice left, to the point where these ice-dwelling animals will be constantly fighting for a place to call home.

    This article suggests that global warming is causing human migration, for similar reasons, especially in Greenland and Northern Alaska. They are affected by the flooding due to ice melting, which is a similar problem to what happens in the Red River Valley. Both the Alaskans and North Dakotans have to move inland sometimes to protect themselves from the flooding.

  3. I was interested in your blog post because I wrote mine on a similar topic. I found out through the articles below that that crabs are moving to the north. This is, like you said, because the ice is melting. But if they continue this they will some sea animals will become extinct. This is because they are feeding off of new animals. Sea animals called echinoderms such as sea urchins, sea lilies, sea cucumbers, starfish and brittle stars. These sea animals have decreased in numbers since the crabs have traveled north. This has started happening recently, as in a few years ago. The crabs are also in danger because they cannot flush magnesium out of their blood causing them to pass out and die. The crabs have been found in some of the deepest water. This is about 3,000 to 4,500 feet below sea level. Since the crabs have started migrating north the water has warmed from 34.2 degrees to 34.6 degrees. So when any animal migrates we know that it will for sure mess up the ecosystem.
