What's "Normal" Weather Is About to Officially Change NCDC's New Weather "Normals" Caused by Climate Shifts

(For a fuller effect of the longer term climatic shift, click through to NASA's site, where you can watch the past 13 decades flash by.)

So the new "normals" will be considerably warmer and wetter than the current set (which you can examine here on the NCDC site). As ClimateWire's Joey Peters explains, this is by no means an academic experiment:

With these changes comes a pronounced effect on the industries and organizations that rely on the normals...[F]or some businessmen, utility regulators, wildlife agencies and others, tinkering with the meaning of "normal" can mean big changes. They range from future sales and budgetary issues to difficulties with songbirds and trout.

So these numbers really do matter, in the very real world. While plenty of agents of disinformation continue to crow about the very recent cold and snow, the biggest businesses, utilities, and agencies have long since recognized and digested the fact that states and smaller regions are warming as well, and their important work depends on how much. They're anxiously awaiting the NDCD's new "normal" weather numbers, and aren't distracted by a short term blast of Arctic air.

NCDC will release the first batch of new "normals" in June, and the rest by the end of the year.
