Climate change debate is overwhelming

To the Editor:

Re: 'Cause of climate change worthy of debate', guest column, Feb. 7.

The ongoing debate about man's role in climate change, at times, is more than just a little overwhelming.

The present cycling started about two-and-a-half million year ago and is continuing.

The last million years have been documented by drill cores from glaciers in Greenland and Antarctica, the CO2 content of the ice is related to the atmospheric temperature.

Man's role today may cause some fluctuations in the cycling, but that is an area of 'who knows?'.

Living here in Northumberland, we have a picturesque landscape due to the last glaciation, the Wisconsin, or in Europe, the Wuurm. The hills are mostly drumlins and the Oak Ridges Moraine gives us a northern border. This moraine is an interglobal moraine from the Wisconsin stadial.

For reasons unknown, many people believe that the 'Ice age' ended 10,000 years ago, but it did not, after the Arctic and Antarctic ice finish melting a new cycle will begin, or one can consider it just as a continuum.

The reasons why the cycling began is unknown, some people blame South America, but we had glaciation in the Precambrian, there is an argument that it is caused by events in outer space, whatever the cause it has been with us for a long time and will continue.

I have even been told the climate problems are more related to the hot air given off by various governments.
