Letter to the Editor – Cool It

Dear Editor,

Cool it! Having read the article “Will Gardening Cool our planet?, I was struck by a number of things.

First, the statement about Canada being the highest polluter in the world needs clarification. Canada is ranked highest on CO2 emissions per capita but 9th in total greenhouse gas emissions (H2O, nitrogen, oxygen, methane, etc). CO2 is NOT a pollutant but is beneficial gas essential to plant growth and the survival of life on the earth, producing more green spaces to live and grow.

Second, CO2 is not THE major contributor to the greenhouse effect (the trapping of the sun’s warmth in a planet’s lower atmosphere). It is known that CO2 is a strong absorber of heat and also a strong emitter of that same heat. Atmospheric CO2 emits as strongly as it absorbs and as it absorbs heat it immediately it. Result – no heat trapped, at least not by CO2!

Third, as we all know, Climate over the millennia has changed in a cyclical manner between warming and cooling it is not static and is naturally reversible – nature rebounds.

Lastly, the article could be recast in a short sentence: “Just a little more carbon dioxide mixed with a little less bureaucratic gas.” And yes, CO2 does cool the atmosphere.
