Letter: Today’s heat isn’t unusual; CO2 is needed to sustain life

The TV weather forecast on May 12 reported record heat across the South. I’m close to 86 in age and grew up in Atlanta. I remember very hot days in the 1930s and ’40s. The May 12 weather forecast made no comparisons with the past. 

How much hotter is it going to get now as compared with 100 years ago, or in the ’30s and ’40s? I am tired of reports about the weather that give no historical comparisons. 

Around 60 years ago, the news on TV was followed by sports. The last two minutes gave us the weather as an afterthought. Today there are 24-hour weather channels that give current data and predictions. We note the predictions four or five days ahead often do not match earlier reports. 

I am not worried about weather change. The Paris Accord admitted that if nothing was done, the average global temperature would rise by 1 degree 100 years from now. We all can live with that.

We moved to Cornelia in April 1999. The climate in Northeast Georgia has varied between hot and dry to hot and wet in the summer. Fall, winter and spring have also been up and down. 

Fact: The average global temperature has risen about 1.5 degrees F since 1880. It will continue rising about 1 degree per century for another 100 to 200 years. A cooling cycle will follow. 

Fact: Greenhouse gas, aka CO2, may help increase the temperature, but the current parts per million levels of CO2 are insignificant. Anyone with some chemical knowledge knows CO2 is vital to any green growth. Cut out CO2 and our plants will starve. Nothing grows without carbon. The ideal level of CO2 is about 2,000 ppm for optimum growth. 

From on Aug. 4, 2006: From June 1-Aug. 31, 1930, there were 21 days of temperature exceeding 100 F in Washington, D.C. That summer has not been approached since then.

Promoting recycling and mulching is necessary.
