Welcome!!!!!

Biology in the News is presented by Dr. Lamar's Biology A/B classes. Each student is responsible for posting ONE blog entry and commenting on ONE post submitted by a fellow student.

About your initial posting . . . . . (approximately 150- 300 words)

Your initial posting is worth 30 points. It must be submitted by October 15th. - Locate an electronic article about a new finding in biology. Article must be been written in the last 12 months. Your posting should include 1) the name of the article (3 point), 2) article source - be specific (3 point), 3) date of article (2 point), 4) link to article (2 points), 5) summary of article in your own words (0-10 points), and 6) significance of article (0-10 points). Comments on significance of article can include (but not be limited to) importance of article to self, to society, or to the further advancement of a particular area of biology.

NOTE: To add link, select text in post that you want to link, click on link icon above posting field, and then paste URL information into appropriate field.

About your comments to a fellow classmate's posting . . . . (approximately 100 - 200 words)

Your comments to another student's posting is worth 20 points. Comments must be submitted between October 16 and November 19 - "The more you know, the more you realize there's a lot more to know" is certainly true to science. Read our Biology in the News blob posts. Pick one post (not your own) and submit comments about this post. Comments should included 1) A question that is raised in your mind by the post. The question should have scientific relevance (0 - 5 points) 2) a response to your question. (0-15 points) Research your question and answer it. If the answer is currently unknown, provide additional background information, describe research that is being done in this field, and/or research that is required for the question to be answered.

Climate Change May Alter Natural Climate Cycles of Pacific

Article Name: Climate Change May Alter Natural Climate Cycles of Pacific
Source: Online magazine

Summary

El Nino is a periodic warming in the eastern tropical Pacific that occurs along the coast of South America, however this phenominom seems to be migrating. El ninos warming is stronger now in the central pacific than the eastern pacific called el Nino Modoki. Scientists believe climate change is responsible for this shift. This latest paper in Nature Geoscience presents evidence that El Nino Modoki drives a climate pattern known as the North Pacific Gyre Oscillation (NPGO). As El Nino Modoki intensifies, so to does NPGO.

Comments

This article does an ok job at informing a person on the climate shift, however, it doesn't explain the consequences this new El Nino Modoki will have when compared to a normal El Nino. Afterall, the (North Pacific Gyre Oscillation) which is affected by El nino Modoki, has a direct impact over "fish stocks and ocean nutrient distributions in the Pacific, especially along the west coast of the United States." I think the fact that this article is relitavley new will ensure follow up articles will be provided. Altough wether the changes will be destructive or not is not the only thing that must be considered. Afterall, any change ill require some enviromental adjustment, which could prove both disasterous and unpredictable.

    Why is El Nino causing North Pacific Gyre Oscillation (NPGO) to intensify and why is it moving more towards the West of the Pacific?

    The answer is with climate changes along with changes in marine ecosystems come shifts in the flow of currents that drive warm or cold weather throughout parts of the Pacific and primarily hot air/weather towards parts of South America.
    Research:
    On the site http://wattsupwiththat.com/2010/10/18/el-nino-modoki-the-big-shifter/ it states that El Nino Modoki, (Modoki meaning similar) causes “changes in ocean circulation of the North Pacific, which scientists now link to an increasing number of dramatic transitions in coastal marine ecosystems.” Emanuele Di Lorenzo an associate professor at the School of Earth & Atmospheric Sciences at the Georgia Institute of Technology said that “NPGO is definitively linked to El Nino Modoki, so as Modoki becomes more frequent in the central tropical Pacific, the NPGO will also intensify.”
