Obama V Cameron's Climate Change Policies: Do We Need To Step Up Our Game?

Over in the UK, David Cameron recently declared the 2015 Conservative government as the "greenest" ever - whilst simultaneously slashing solar power subsidies, cancelling plans to build onshore wind farms and canning requirements for new homes to be zero carbon.

After Ed Miliband said the urgency to address the climate change problem had gone out the window, perhaps it's time we stepped up our game?
