There are many references on the web to the relationship between clear cutting and global warming. This little piece is from the National Academy of Sciences:

Global Warming Facts & Our Future

Land Use Changes

When humans transform land from forests to seasonal crops or from natural to urban environments, the regional climate system is altered. For example, clear-cut hillsides are significantly warmer than forests. Urban environments are also islands of heat produced by industry, homes, automobiles, and by asphalt’s absorption of solar energy. Land use changes are not likely to have a large, direct effect on global average temperature.

Changing uses of the land are also associated with changes in the usage and availability of water, as well as the production of greenhouse gases. Deforestation can significantly increase the amount of atmospheric CO2, which warms the planet.
