Corals moving to more tolerable temperatures



Click here and read this article
Answer the questions below in paragraph format. Then, comment thoughtfully in the form of a question on a peer's post.  Both posts will be graded. They are due Monday, Feb. 13th.

What is the name of the type of coral that has not done well in the Great Barrier Reef but is doing better in the previously cooler waters of Western Australia?


After reading the article, come up with an explanation of why the corals are doing better in their newer location?



Which variable (ocean acidification or temperature) appears to have a greater impact on these types of corals?  Why might it be too soon to tell?


What process (related to corals) is sensitive to changes in pH and temperature?


What does this article show about the scientific process? Does this article dispute the effects of global warming on organisms? Support your answer with evidence.

What states now have stable gray wolf populations and what has happened in terms of their legal status as a result?


What is the California wolf looking for? Will it be successful?


What group of stakeholders is pleased that the wolf has made an entrance into California? Who is against it and why?


Do you think that gray wolves should be protected despite their impact on livestock?

China talks about Climate Change before the UN Summit on Climate Change on Dec. 9th

http://www.csmonitor.com/Science/2011/1122/China-Economic-woes-no-excuse-for-climate-change-inaction/(page)/2

Read this article also: http://www.guardian.co.uk/environment/2011/nov/20/rich-nations-give-up-climate-treaty?newsfeed=true

What are the actions that China would like to see taken by developed countries to curb greenhouse gases?  How will the global economic crisis impact the rate of change in terms of curbing greenhouse gases (in your opinion)?  Is the economic crisis a good enough reason to allow countries to continue emitting carbon dioxide (CO2), methane (CH4), and other greenhouse gases?  Why or Why not?
Who is the number one emitter of these gases? What is their 2020 goal? Is this goal, in your opinion, good enough?

Sept. 6-9th Carbon Cycle and Global Warming

Read this recent article about a glacier in Greenland: http://www.bbc.co.uk/news/uk-wales-mid-wales-14771523

Why do you think the glacier is melting at such a rapid rate? What does this glacier's demise have to do with the carbon cycle?

What other evidence is there for the correlation between carbon dioxide levels and increasing average global temperatures?
