Climate change and 400 ppm carbon dioxide

In the great carbon cycle that is at work on our planet, carbon dioxide (CO2) gas concentration in our atmosphere, as measured in the most famous observation site in the world (Mauna Loa, Hawaii, home of the Keeling Curve), has … Continue reading

CO2 trends from around the world

Time series are profilic in climate science. This is a dataset that shows the how a measurement changes over some period of time. The best known in our world is the global warming time series displayed as the globally-averaged surface … Continue reading

CO2 in the very merry month of May

The whole month has been an edge-of-your-seat wait-and-see when CO2 will stop hovering above and below 400 ppm and just stay above. Unlike Miguel Cabrera‘s triple crown of 2012 or the thoughts that he could repeat that feat in 2013 … Continue reading

Another week of CO2 from Scripps

An update to my update from the original post. CO2 is rising 2 ppm/year and has been for about the last decade (see graph here). So the daily ups and downs and pretty miniscule. 2 ppm/year is 0.0055 ppm/day, or … Continue reading

CO2 hovering above and below 400 ppm

An update from the measurements being reported from Scripps that I discussed earlier. Here’s the screen shot when I checked the “box scores” for our favorite greenhouse gaswhew! I know if I patiently wait, the CO2 concentration will rise above … Continue reading

Carbon dioxide concentrations are nearly 400 ppm

The latest reported value from 4th of May 2013 was 399.68 ppm. That’s as close to 400 ppm as we (our civilization and planet, that is) have gotten. The best place to see the rapidly updated CO2 concentrations is at … Continue reading
