NPR reports on climate change trends for the world starting in 2006 and the predictions for 2030. The plot of atmospheric carbon dioxide levels and the chart of carbon dioxide emissions versus GDP is informative. The US and China produce roughly the same amounts of CO2. The US GDP is 3 times that of China. The European Unions GDP is greater than the US and its carbon production is 2/3rds that of the US. The GDP to carbon ratio is a good measure of a country's efficiency.
Country GDP$billion/Metric ton CO2
China 0.6
Russia 1.0
India 1.0
US 2.0
Brazil 2.0
EU 3.4
Germany 3.9
Japan 4.0
The carbon dioxide data above mirrors the outdoor carbon dioxide data I have taken
during the course of indoor air investigations. I will take an outdoor control reading to check the
field calibration of my instrument along with regular calibration with a known concentration.
In the middle 80's I was measuring outdoor carbon dioxide at 340 ppm. I now measure
outdoor levels of 380 ppm carbon dioxide.
