Module 4 Discussion

Human-induced climate change remains a controversial topic with a lot of misinformation on both sides of the political spectrum. Discuss the following aspects of some of the more common claims about global warming. A very good website that discusses some of these topics is the Skeptical Science website.

• The sun is causing most of the warming of the Earth.
• Scientists don’t really agree on global warming.
• It hasn’t warmed since 1998 and therefore global warming really isn’t happening
• Antarctica is actually gaining ice.
• We have had some very severe winters recently, evidence the Earth is not warming.
• Cities have grown in size and cities are generally warmer than the surroundings creating a false temperature reading.
• The temperature record is unreliable and therefore we really don’t know what’s going on.

Make sure to:

• Write a short essay or paragraph of at least 300 words.
• Use concrete examples/details and avoid generalities.
• Address all questions.
• Use proper grammar and punctuation.
• If you researched your topic and are using information from what you learned, remember to cite your sources.
• Do not plagiarize.
• You will not be able to edit your assignment once you post, so please proofread and spell check before hitting post!
• As part of the assignment, you must also reply to ONE of your classmates with at least 150 words. You will have to POST FIRST to see your classmates’ postings. Make sure your replies are a thoughtful and relevant to what your classmate has posted. Try to build the discussion and keep it going.
