Carbon Dioxide | Global Warming

Rush Limbaugh talked about global warming yesterday. He pointed out that carbon dioxide has increased 50% in the last ten years, but global temperatures have remained flat. There’s a little graph on this article, which depicts temperature changes over the last ten years. The same article says that:

Industrial carbon-dioxide emissions have risen by 50% since 1997.

People still say that  carbon dioxide emissions cause global warming in spite of these observations.

The sun has been getting hotter for years.

It is possible that the sun causes global warming…and that carbon dioxide emissions do not cause global warming.
