By deciding to reject the Paris agreement on climate change, President Trump signals that the US is not serious about combating global warming. A unified stance among these seven countries would show the rest of the world that the future of all our children and their children matters. The science behind the threat of climate change is well established and new data regarding its impact on the Antarctic and Greenland ice sheets is a resounding confirmation. Mr. Trump may not see the issue the way everyone else does but taking off those blinders may be the solution.
