This global map of PM2.5 shocked me at first
sight. It shocked me because China was marked as the most, and possibly the
only seriously affected area across the world. What appeared to people from other
countries as dark red meant real life to Chinese, or life-threatening.
Before this visual experience, I knew that
pollution in China was terrible. But I didn’t know it was to the degree of
“dark red”. And I decided to migrate after that.
The map was created by two Canadian
researchers who blended “total-column aerosol amount measurements from two NASA satellite
instruments with information about the vertical distribution of aerosols from a
computer model”. The quoted remarks made no sense to me, but they suggest the
scientificity and the accuracy of the data. The researchers’ decision to
transform the cold numbers into colors was amazing.
And that made me wonder about the
presentation of my own research data about the reasons that cause ESL teachers
change their practice of copyright compliance, and I figure there would be
multiple “shades of grey”. J
