Carbon emissions

I’m appalled by John A. Lanzetta’s April 27 letter in which he dismisses the role played by man-made carbon emissions in the increase of atmospheric carbon dioxide.

He claims that the majority of the elevated levels of carbon dioxide comes from natural sources such as volcanoes and forest fires.

However, natural forces like volcanoes have been at work for millions of years, but the dramatic increase in atmospheric carbon dioxide, as well as melting glaciers and polar ice caps, has only been observed within just the past century.

Natural forces such as volcanoes have existed in equilibrium with the atmosphere for eons, but not man’s runaway deforestation and burning of fossil fuels, which are unsustainable.
