While researchers have sometimes connected weather extremes to man-made global warming, usually it's not done in real time.

The United States just came out of a two-faced winter - bitter cold and snowy in the Midwest and East, warm and severely dry in the West. The latest U.S. drought monitor says 100 percent of California is in an official drought.

The new study blames an unusual "dipole," a combination of a strong Western high pressure ridge and deep Great Lakes low pressure trough. That dipole is linked to a recently found precursor to El Nino, the world-weather changing phenomenon. And that precursor itself seems amplified by a build-up of heat-trapping greenhouse gases, the study says.

It's like a complex game of weather dominos that starts with cold water off China and ends with a devastating drought and memorable winter in the United States, said study author Simon Wang, a Utah State University climate scientist.

Wang was looking at colder water off China as a precursor to an El Nino. The colder water there triggers westerly winds in the tropical Pacific. Those westerly winds persist for several months and eventually push warmed up water and air to the central Pacific where an El Nino forms, Wang said.

An El Nino is a warming of the central Pacific once every few years, from a combination of wind and waves in the tropics. It shakes up climate around the world, changing rain and temperature patterns. Wang saw the precursors and weather event coming months before federal weather officials issued an official El Nino watch last month.

Then Wang noticed the connection between that precursor - cold water off China, Vietnam and Taiwan - and the recent wild winter. He tracked similar combinations of highs and lows in North America. And he found those combination extremes are getting stronger.

A WARNING to All Mankind of an Imminent Global Warming Apocalypse ...Immediately followed by a WARNING for all Mankind to not share their Revelations!

That pretty much sums up the bogus nature of the "crisis".
