Sioux Falls Scientists present CO₂ (carbon dioxide) increase charts which
show no decrease in the rate of CO₂ increase for the last 50 years.
CO₂ is a potent greenhouse gas which, once there, takes a
very long time to remove from the atmosphere.

CO₂ Increase Charts
CO₂ is now increasing at the rate of 4 ppm per year.
The trend rate has been steadily increasing. We have
yet to do anything to make any significant difference.

Recent Monthly Average Mauna Loa CO₂
June 2017:       408.84 ppm
June 2016:       406.81 ppm

The chart above shows the cycle of the huge Canadian and Russian forests adsorbing CO₂, first shutting down in winter and then followed by the leaves coming out in early summer and again absorbing CO₂. This cycle has been going on for millions of years. This cycle has kept the CO₂ levels at an average of 278 parts per million during the interglacial periods for the last 400,000 years. With the advent of the industrial revolution in 1860, however, the amount of CO₂ being pumped into the atmosphere has exceeded the ability of the world's forests and jungles to keep up with it. The CO₂ has now accumulated in the atmosphere to point where it is now at 405 PPM, a 45 percent increase. The forests and jungles love it, but we humans are not going to do very well as the Arctic, Antarctic and mountain glaciers melt, the oceans rise and the global climate gets much, much warming.
