Cooling And Warming Cause Snow... Not Exactly

SEARCH BLOG: GLOBAL WARMING

In a desperate attempt to convince the world that black is white and hot is cold, Al Gore reiterates the concept that global warming causes more snow. So let's take a macro look at what has happened in the U.S. [data shown below is for the entire northern hemisphere].

From Watts Up With That?

Now that we have reached the end of the meteorological winter (December-February,) Rutgers University Global Snow Lab numbers (1967-2010) show that the just completed decade (2001-2010) had the snowiest Northern Hemisphere winters on record. The just completed winter was also the second snowiest on record, exceeded only by 1978. Average winter snow extent during the past decade was greater than 45,500,000 km2, beating out the 1960s by about 70,000 km2, and beating out the 1990s by nearly 1,000,000 km2. The bar chart below shows average winter snow extent for each decade going back to the late 1960s.

....................Cooling.......................Warming........................Cooling

Mr. Gore would have to argue that the decade of the 80s and 90s, which were a warming period in the U.S., should have had more snow coverage and extreme snowstorms... but they didn't. The decades of the 60s and 70s which were notoriously cold in the U.S. ... so much so that newspapers and magazines were hyping a new "ice age"... had more snow coverage than the 80s and 90s. This decade of cooling in the U.S. has coincided with more record cold temperatures and more record snowfall.
I remember arriving in Grand Forks AFB, North Dakota in November of 1968 and being given an "orientation" that included pictures of snow covering the entire first story, and sometimes second stories, of buildings a couple years back and being warned of "severe arctic" winters. Temperatures of minus 30° F were common in the winter as were freezing deaths. "Snow packing" was a well-known condition when snow, driven by very high winds, would accumulate in the engine compartment of running vehicles where it would melt and short out the electrical system. The vehicle would then stall and could not be restarted. I know because I was in a vehicle when that occurred.

I remember moving to Michigan in the early 70s and buying a home in the late 70s and then equipping it with central air conditioning in early 80s ... just in time to ward off a summer with over 30 days of 90°+ temperatures... the same time we were having winters when a broom was all that was needed to keep the driveway clear of snow.
Perhaps anecdotal remembrances are not sufficient explanation that snow and cold go together and that snow is less prevalent during warming periods... but the data above should be somewhat more compelling and less strain on credulity than Mr. Gore's assertion that greater warmth brings more snow. Maybe more rain? Maybe longer growing seasons? Definitely less snow.

There is always an easy solution to every human problem—neat, plausible, and wrong.

... and one could add "not all human problems really are."
It was beautiful and simple, as truly great swindles are.

... The Government is on course for an embarrassing showdown with the European Union, business groups and environmental charities after refusing to guarantee that billions of pounds of revenue it stands to earn from carbon-permit trading will be spent on combating climate change.

Go back to 1999-2000 and see what the Fed did. They are following the same pattern for 2005-06. If it ain't broke, the Fed will fix it... and good!
August 29, 2006 The Federal Reserve always acts on old information... and is the only cause of U.S. recessions.
December 5, 2006 Last spring I wrote about what I saw to be a sharp downturn in the economy in the "rustbelt" states, particularly Michigan.
March 28, 2007
The Federal Reserve sees no need to cut interest rates in the light of adverse recent economic data, Ben Bernanke said on Wednesday.
The Fed chairman said ”to date, the incoming data have supported the view that the current stance of policy is likely to foster sustainable economic growth and a gradual ebbing in core inflation”.

July 21, 2007 My guess is that if there is an interest rate change, a cut is more likely than an increase. The key variables to be watching at this point are real estate prices and the inventory of unsold homes.
August 11, 2007 I suspect that within 6 months the Federal Reserve will be forced to lower interest rates before housing becomes a black hole.
September 11, 2007 It only means that the overall process has flaws guaranteeing it will be slow in responding to changes in the economy... and tend to over-react as a result.
September 18, 2007 I think a 4% rate is really what is needed to turn the economy back on the right course. The rate may not get there, but more cuts will be needed with employment rates down and foreclosure rates up.
October 25, 2007 How long will it be before I will be able to write: "The Federal Reserve lowered its lending rate to 4% in response to the collapse of the U.S. housing market and massive numbers of foreclosures that threaten the banking and mortgage sectors."
November 28, 2007 FED VICE CHAIRMAN DONALD KOHN
"Should the elevated turbulence persist, it would increase the possibility of further tightening in financial conditions for households and businesses," he said.

"Uncertainties about the economic outlook are unusually high right now," he said. "These uncertainties require flexible and pragmatic policymaking -- nimble is the adjective I used a few weeks ago."

December 13, 2007 [from The Christian Science Monitor]
"The odds of a recession are now above 50 percent," says Mark Zandi, chief economist at Moody's Economy.com. "We are right on the edge of a recession in part because of the Fed's reluctance to reduce interest rates more aggressively." [see my comments of September 11]
January 7, 2008 The real problem now is that consumers can't rescue the economy and manufacturing, which is already weakening, will continue to weaken. We've gutted the forces that could avoid a downturn. The question is not whether there will be a recession, but can it be dampened sufficiently so that it is very short.
January 11, 2008 This is death by a thousand cuts.
January 13, 2008 [N.Y. Times]
“The question is not whether we will have a recession, but how deep and prolonged it will be,” said David Rosenberg, the chief North American economist at Merrill Lynch. “Even if the Fed’s moves are going to work, it will not show up until the later part of 2008 or 2009.
January 17, 2008 A few days ago, Anna Schwartz, nonagenarian economist, implicated the Federal Reserve as the cause of the present lending crisis [from the Telegraph - UK]:
The high priestess of US monetarism - a revered figure at the Fed - says the central bank is itself the chief cause of the credit bubble, and now seems stunned as the consequences of its own actions engulf the financial system. "The new group at the Fed is not equal to the problem that faces it," she says, daring to utter a thought that fellow critics mostly utter sotto voce.
January 22, 2008 The cut has become infected and a limb is in danger. Ben Bernanke is panicking and the Fed has its emergency triage team cutting rates... this time by 3/4%. ...

What should the Federal Reserve do now? Step back... and don't be so anxious to raise rates at the first sign of economic improvement.
Individuals and businesses need stability in their financial cost structures so that they can plan effectively and keep their ships afloat. Wildly fluctuating rates... regardless of what the absolute levels are... create problems. Either too much spending or too much fear. It's just not that difficult to comprehend. Why has it been so difficult for the Fed?
