The warnings in the National Climate Assessment released earlier this week could not have been louder, predicting intensifying heat, torrential downpours and rising seas. And when President Obama spoke about the report, he was clear as well. "This is not some distant problem of the future," Obama told The Today Show's Al Roker on May 7. "This is a problem that is affecting Americans right now."
But if climate change is the problem, what's the solution? Today Obama began to answer that question, announcing several executive actions on renewable energy and energy efficiency at a speech he'll give later today at a Walmart in Mountain View, California. Those actions include a plan to drive $2 billion in energy efficiency upgrades to Federal buildings over the next three years, using long-term energy savings to pay for up-front costs. The Department of Energy will issue two final energy efficiency conservation standards for industrial products like escalators and walk-in supermarket freezers, as well as tougher new building efficiency standards. Altogether the White House expects that the actions will push private companies to invest an additional $2 billion in energy efficiency, and will cut carbon pollution by more than 380 million metric tons—equivalent to taking 80 million cars off the road for a year.
That's nice—and the President will also announce plans by a number of housing developments to increase their use of solar power—but it's important to remember that the U.S. alone emits more than 6.5 billion metric tons of greenhouse gases. These new executive actions are small bore compared to the sheer size of the climate challenge—although they are taking place against the backdrop of rapid growth in the U.S. solar industry, which has increased nearly elevenfold since Obama took office. The selection of a Walmart for today's announcement—while controversial with labor activists—isn't accidental. Walmart already gets about a quarter of its electricity from solar, far more than the country as a whole, and the company has been a leader in energy efficiency for some time. Walmart might not be a political ally to President Obama most of the time, but the retail giant is light-years ahead of most of corporate America when it comes to climate change.
But energy efficiency and solar power are comparatively easy climate policies. The real challenge will come when the Environmental Protection Agency issues regulations on the amount of carbon that can be emitted by existing power plants, the single biggest source of greenhouse gases—and the single biggest action Obama can take to answer the climate challenge. Today's announcement in Mountain View is just a warm-up. The marathon is still ahead.
