How are CO2 Data Processed?
Scientists make CO2 measurements in remote locations to obtain air that is representative of a large volume of Earth’s atmosphere and relatively free from local influences that could skew readings.
How Much CO2 Can The Oceans Take Up?
A companion phenomenon of emitting CO2 into the atmosphere is the loading of the oceans with elevated levels of carbon dioxide created by fossil fuel burning and other human activities.
Why are Seasonal CO2 Fluctuations Strongest at Northern Latitudes?
The farther north a CO2 reading is made, the wider it swings with the seasons
