A group of American and Canadian marine biologists have found that marine mammals are very useful for collecting information abuot the changing arctic. Seals, walruses, and polar bears all depend on the ice for a habitat and are being forced to adapt to the loss of ice. The scientists are able to moniter to the timing of the animals' movements, shifts in distribution, and where the animals are feeding. The mammals also show changes in their diet and physical condition.
NOS Themes:
- Science is collaborative: Americans and Canadians worked together.
- Roll of credibility: The story was provided by the National Oceanic and Atmospheric Administration.
- Importance of repeatability: The research has been repeated with many different individual animals as well as different species.
I think that this article will help us be able to track the animals and also be able to learn more about global warming.
ReplyDeleteI feel that with this new way of tracking global warming we as humans should be able to realize how big of a problem this actually is and make a effort to stop it. According to nationalgeographic.com average temperatures have climbed 1.4 degrees Fahrenheit since 1980, and this rate of warming is steadily increasing. According to climate studies, the last two decades were the hottest in 400 years and possibly the warmest for several millennia. This causes Arctic Ice, glaciers, and mountain snows to rapidly disappearing and is also causing bleaching of sea corrals which respond to the smallest change in temperature.

I really enjoyed this articles, and I feel like this experiment will really give us a new understanding of the arctic animals and the conditions they are facing. This will be very helpful in the science community to know more about.
