"Excessively high temperatures" are "already" harming public health nationwide, Pres. Obama declared on Nov. 1, 2013, two months before today's assault by record low temperatures.

In his executive order on climate change, Obama warned that too much rain - and not enough rain - also dictated that executive action against climate fluctuations:

"The impacts of climate change -- including an increase in prolonged periods of excessively high temperatures , more heavy downpours, an increase in wildfires, more severe droughts, permafrost thawing, ocean acidification, and sea-level rise -- are already affecting communities , natural resources, ecosystems, economies, and public health across the Nation . These impacts are often most significant for communities that already face economic or health-related challenges, and for species and habitats that are already facing other pressures."

What's more, climate control "requires" action "by the Federal Government" (as opposed to the federal government), Obama declared:

"Managing these risks requires deliberate preparation, close cooperation, and coordinated planning by the Federal Government , as well as by stakeholders, to facilitate Federal, State, local, tribal, private-sector, and nonprofit-sector efforts to improve climate preparedness and resilience; help safeguard our economy, infrastructure, environment, and natural resources; and provide for the continuity of executive department and agency (agency) operations, services, and programs."

But, today's Accuweather.com forecast warns that the imminent danger in the U.S. is cooling, not warming:

"This brutal cold will bring danger to millions from the northern Plains to the Midwest and down into the Tennessee Valley. Overnight lows are forecast to dip well below the zero-degree mark in these areas, even dropping to 30 below zero in parts of Minnesota and North Dakota."
