Weather extremes are expected from time to time regardless of the overall climate trend. I see in Midwest they got more than a foot of snow..but New York was at 70 degrees F at the same time.
Trying to equate GWE's to an actual climate trend or pattern (unless you are seeing alot of these GWEs over a broad geographic range for an extended period) would be akin to saying the 2004 tsunami was proof of rising sea levels.
On the otherhand, these GWEs can be cyclic and normal in nature. For instance, historical records show that the Nile River actually froze over in 829AD and 1010AD (this coincides with an aproximate 200 year climate cycle that happens to follow the same 200 year solar cycle. Following this 200 year trend cycle and you find we are in the right timeframe for cold extremes. Note the current dead quiet of the sun and recent snow events in Isreal, Baghdad, Terhan, mid-southern China, and the summertime snow that occurred in South America, South Africa, and Oz.
Again, the problem with trying to say whats a geologic trend and whats a shorter natural cycle.As for your idea of rapid response teams..that would be good except you have to consider the airports may be closed due to the bad weather so you wouldn't be able to get in their in any time to help anyways.
A bulldozer/shovel makes an adequate snow clearing device (the typical snow plow mounted to trucks for winter snow clearing are essentially light weight dozer blades mounted to a trucks bumber frame)...especially for areas that don't often see snow. Why pay a bunch of money for something that MAY be used only once or twice a year (not to mention the operator) when alternative methods exist?
Now, if this type of weather continues and looks like it will set a pattern of being the winter normal...then a sumertime purchase of actual snow removal equipment should be looked at. Cheaper to buy in summer and gives you a 4 month window to train operators.
In China's case they would be suited for use and maintaining by the various PLA bases since the PLA is ofthen used as China's version of States Guard units in the US.
If this was just a freek area/time of GWE...use what you have and save the money for rebuilding.

Remember the pics i posted that showed the differences in the sun from 2002 and 2008.
Looks like some other people are taking notice.
These points are real telling:
For instance, researchers at the Max Planck Institute for Solar Research in Germany report the sun has been burning more brightly over the last 60 years, accounting for the 1 degree Celsius increase in Earth's temperature over the last 100 years.CO2 variations show little correlation with our planet's climate on long, medium and even short time scales. "Solar activity has overpowered any effect that CO2 has had before, and it most likely will again," Patterson says. "If we were to have even a medium-sized solar minimum, we could be looking at a lot more bad effects than 'global warming' would have had." The study says that "try as we might, we simply could not find any relationship between industrial activity, energy consumption and changes in global temperatures."
The study concludes that if you shut down all the world's power plants and factories, "there would not be much effect on temperatures."
On a side note...whats the REAL word on the winter rice crop? I heard it was pretty well ruined by the extreme weather.

by moon. Ask any knowledgeable person if Tide is Just like Galileo's statement of Earth revolving around the Sun was put down. Unless you both are know-all you can not disprove anything. Just like the Church could not disprove the Galileo's statement of Earth revolving around the Sun. My post is for Short takes not for you two morons. Study more and be more knowledgeable before you open your big stupid ugly smelly mouths. STFU! LMAO! Cocksair, I really did not know you lack such such very basic Scientific and General knowledge, Read more below: .. Lunar Tides The tides at a given place in the Earth's oceans occur about an hour later each day. Since the Moon passes overhead about an hour later each day, it was long suspected that the Moon was associated with tides. Newton's Law of Gravitation provided a quantitative understanding of that association.
Differential Forces
Consider a water molecule in the ocean. It is attracted gravitationally by the Earth, but it also experiences a much smaller gravitational attraction from the Moon (much smaller because the Moon is much further away and much less massive than the Earth). But this gravitational attraction of the Moon is not limited to the water molecules; in fact, the Moon exerts a gravitational force on every object on and in the Earth. Tides occur because the Earth is a body of finite extent and these forces are not uniform: some parts of the Earth are closer to the Moon than other parts, and since the gravitational force drops off as the inverse square distance, those parts experience a larger gravitational tug from the Moon than parts that are further away. In this situation, which is illustrated schematically in the adjacent figure, we say that differential forces act on the body (the Earth in this example). The effect of differential forces on a body is to distort the body. The body of the Earth is rather rigid, so such distortion effects are small (but finite). However, the fluid in the Earth's oceans is much more easily deformed and this leads to significant tidal effects.
A Simple Tidal Model
We may illustrate the basic idea with a simple model of a planet completely covered by an ocean of uniform depth, with negligible friction between the ocean and the underlying planet, as illustrated in the adjacent figure. The gravitational attraction of the Moon produces two tidal bulges on opposite sides of the Earth. Without getting too much into the technical details, there are two bulges because of the differential gravitational forces. The liquid at point A is closer to the Moon and experiences a larger gravitational force than the Earth at point B or the ocean at point C. Because it experiences a larger attraction, it is pulled away from the Earth, toward the Moon, thus producing the bulge on the right side. Loosely, we may think of the bulge on the left side as arising because the Earth is pulled away from the water on that side because the gravitational force exerted by the Moon at point B is larger than that exerted at point C. Then, as our idealized Earth rotates under these bulges, a given point on the surface will experience two high and two low tides for each rotation of the planet.
More Realistic Tidal Models
The realistic situation is considerably more complicated: 1. The Earth and Moon are not static, as depicted in the preceding diagram, but instead are in orbit around the common center of mass for the system. 2. The Earth is not covered with oceans, the oceans have varying depths, and there is substantial friction between the oceans and the Earth. These make a more realistic description much more complicated, but the essential ideas remains as illustrated in the preceding diagram. Here are realtime links to the present tidal conditions in San Francisco Bay and Houston-Galveston and here is a link to a set of graphs for the tidal levels over current 24-hour periods for various tidal stations. Notice in comparing these graphs the differences in the detailed tidal fluctuations for different locations (for example, compare the graph for Tacoma, Washington, with that for South Pass, Louisiana). These differences are produced by the complicating factors mentioned above.
Spring Tides and Neap Tides
Another complication of a realistic model is that not only the Moon, but other objects in the Solar System, influence the Earth's tides. For most their tidal forces are negligible on Earth, but the differential gravitational force of the Sun does influence our tides to some degree (the effect of the Sun on Earth tides is less than half that of the Moon). Competition between the Sun and Moon in producing tides.
For example, particularly large tides are experienced in the Earth's oceans when the Sun and the Moon are lined up with the Earth at new and full phases of the Moon. These are called spring tides (the name is not associated with the season of Spring). The amount of enhancement in Earth's tides is about the same whether the Sun and Moon are lined up on opposite sides of the Earth (full Lunar phase) or on the same side (new Lunar phase). Conversely, when the Moon is at first quarter or last quarter phase (meaning that it is located at right angles to the Earth-Sun line), the Sun and Moon interfere with each other in producing tidal bulges and tides are generally weaker; these are called neap tides. The figure shown above illustrates spring and neap tides.
Tidal Coupling and Gravitational Locking
We have introduced tides in terms of the effect of the Moon on the Earth's oceans, but the effect is much more general, and has a number of important consequences that we will discuss further below. For example, as a consequence of tidal interactions with the Moon, the Earth is slowly decreasing its rotational period and eventually the Earth and Moon will have exactly the same rotational period, and these will also exactly equal the orbital period. Thus, billions of years from now the Earth will always keep the same face turned toward the Moon, just as the Moon already always keeps the same face turned toward the Earth.
