Java Canadian scientists and Global warming

Canadian scientists have published research proving that CFCs, not carbon dioxide emissions, are the key driver of climate change. CFCs are gases that were widely used in refrigerators and aerosols, but whose use is being phased out because they damage the ozone layer.

This explains why the earth has actually been cooling since 2002, matching the fall in CFCs in the atmosphere.

Data recorded from 1850 to 1970, when there were no significant CFC emissions, show that although carbon dioxide levels increased significantly because of industrialization, when solar-cycle effects are excluded, global temperatures were nearly constant – they only started to rise with the arrival of the CFCs. Now both are falling.

“The cooling trend is set to continue for the next 50 to 70 years as the amount of CFCs in the atmosphere continued to decline,” says Qing-Bin Lu, professor at the Waterloo University’s Faculty of Science.
