More fracking and fewer green subsidies are the most effective answers to global warming,left-leaning but “skeptical environmentalist” Bjorn Lomborg said Monday.

Fracking is a drilling practice that extracts natural gas and oil from shale rock formations by injecting water and chemicals deep underground to make the resources more easily recoverable. Instead of pouring money into “inefficient, feel-good policies” like solar panels and electric cars, countries should invest in fracking, Lomborg wrote in a Globe and Mail op-ed.
