Global Warming - No Doubt About It

The National Climatic Data Center has just reported that October was the 332nd month in a row of above-average global temperatures. 

That is 27 years.

I believe the globe is warming up - I am not sure what is causing it.

Here is an example of how geology can affect weather and climate - 

In 1815  the eruption of the volcano Tambora  on the Indonesian island of Sumbawa  caused the ''year without a summer'' in 1816  when so much ash was carried into the upper atmosphere that it blocked the sun; it snowed in Boston in June and a famine spread across parts of Europe.
