Description

Do some research and cite other factors in climate besides CO2 levels that would support or detract from the idea of global warming and sea-level Internet sources, tell what the expected rise in sea level is by the year 2050 and discuss at least three major ways this will affect islands or coastal areas. You can quote Al Gore if you like but let's leave Donald Trump out of it. Think about places like Florida, Louisiana, and many small island nations in the Pacific. Not to mention NYC and read the article about Norfolk "Built on Sinking Ground" an area many of you know well. Ask yourselves: what can the Dutch do that we couldn't do after you read the attached articles. Please open and read all of these articles.

I would also like to recommend the excellent book on this topic by John McPhee called: "The Control of Nature". It's a great book and would be useful for anybody taking environmental studies/policy or disaster management courses (great basis for a research paper, hint, hint). It covers exactly what happened along the Mississippi River in 2011.

So much has been put out in the media about global warming and the "greenhouse effect". Now the Earth has had wide variations in atmospheric CO2-level throughout its long history before the evolution of humans and certainly before the Industrial terms of the oceans and the Earth's whole history then could you find information to support the coal and oil industry's claims that we're NOT the cause of climate change? Also read the attached article about the controversy. Remember too that there is a lot of money and certainly politics involved in this issue. Some scientists have built their whole careers on trying to prove or disprove the human connections to global warming.

As you'll see when you do your research the figures for sea-level rise are all over the place. That's because they're based on models that are even more complex than hurricane tracking models (they drive even supercomputers nuts). Now the term "sea-level" is relative. If you check a geologic map you'll see that just about every piece of land on Earth has been underwater at least once (that's why sedimentary rocks are the most common type of land surface rock). Look at the map of N. America on pg 67 in the text. The large tan area in the Mid-West was once a shallow sea. Sea-level has been up and down thousands of times in the Earth's long history. We're just living on the "latest edition" of our planet. Also the one thing that I want everybody to learn from this course: we live on the Earth and we certainly affect it but we DO NOT control it even though we like to think we do. We're just riding this wet rock through space.
