TORONTO – NASA has released visualizations for two different climate scenarios, showing dramatic changes due to the increase of carbon dioxide levels in the atmosphere.
For the precipitation model, both scenarios show dry regions getting drier and wet regions getting wetter.
As for temperature changes, using these two models, much of Canada would see a temperature change of close to 4 C by 2043 if carbon dioxide emissions rose to 500 parts per million (ppm). That means for every one million molecules of air, there are 500 parts of carbon dioxide.
The same holds true for the second scenario of 800 ppm. However, after 2043, the change becomes more dramatic with a temperature difference of more than 8 C by 2100.
The latest carbon dioxide reading by the Scripps Institute of Oceanography has been 367 ppm.
The visualizations combine results from 15 global climate models and show changes from 2000 to 2100 compared to the average from 1970 to 1999.
