Discussion:
Human-induced climate change remains a controversial topic with a lot of misinformation on both sides of the political spectrum.
Discuss the below 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.
