Atmospheric greenhouse gases are a bit of an abstraction. We can’t see them, we can’t smell them, and we can’t immediately tell when there is a change in concentration.
The site CO2Now is trying to change that by showing current data for atmospheric CO2 and helping people understand the relationship between current trends of rising CO2 levels and the effects of climate change. “The site puts atmospheric CO2 out in front where it needs to be,” says website founder Michael McGee. “It’s a simple thing that no other website is doing. I started posting atmospheric CO2 data in December 2007 when I realized it was a way I could add value to the climate conversation.”
The site also helps explain the factors that effect climate, the relationship between climate and weather and the effects of climate change like ocean acidification and reductions in global land ice. “Atmospheric CO2 is a big picture metric that hardly gets talked about outside of scientific circles,” adds McGee. “CO2Now.org was created so anyone on the internet can see the changes in the atmosphere as they happen. It presents the trend information so people can see whether or not we are doing enough to end global warming.”
