Climate change denier

A good friend of mine is fun, quick and smart.

I think he's also wrong in term of his assessment about what causes climate change. At times, he sounds like one of these climate change deniers.

When I tell him that the weather is going to the dogs in terms of temperature rising, he reminds me of the “Little Ice Age” that spanned from the 14th to the end 19th century.

There seems to have been several reasons for it: Low points in solar radiation, heightened volcanic activity, changes in oceanic currents, variations in earth's orbit and axial tilt, inherent variability in global climate, and decreases in the human population.

This period was preceded by an exceptionally warm period from the 10th to the 13th century when vineyards were spotted in some high alpine valleys of Europe. So he thinks that what we're experiencing now is a repeat performance of that milder period.

I cannot agree with him when I look at this NASA chart that only goes to 2004 (since then, temperatures kept on climbing).

Ever since the beginning of the Industrial Revolution, planetary temperature rise is out of control and should be explained by the confluence of the industrial age and a human overpopulation that has exploded more than five-fold!
