Assignment

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.
