Researchers develop idea of resurfacing urban areas to offset CO2 emissions

In a study published in the Institute of Physics's Publishing’s journal Environmental Research Letters, researchers from Concordia University created this scenario to see what effect a global increase in surface reflectance would have on global temperature and our own carbon dioxide (CO2) emissions. They estimate that increasing the reflectance -- commonly known as albedo -- of every urban area by 0.1 will give a CO2 offset between 130 and 150 billion tonnes. This is...
