White House commitment to reversing climate change

President Obama believes that no challenge poses a greater threat to our children, our planet, and future generations than climate change .. .. .. That’s why under President Obama’s leadership, the United States has done more to combat climate change than ever before. Note: The photo below shows a frozen ocean off of Woods Hole Research Center, Massachusetts - in February / March, 2015. Obama's own supporters were surprised to see this rare event of a frozen ocean at Woods Hole. Their website says: "I'm with science. Climate Change is no Hoax." Shouldn't these scientists and the White House check the weather by looking out the window? Is carbon dioxide one of the essential molecules of life? Is it a pollutant at anywhere near today's concentrations?
