I am speechless

I can't even muster up a response to this from the house side of S. Dakota:

NOW, THEREFORE, BE IT RESOLVED, by the House of Representatives of the Eighty-fifth Legislature of the State of South Dakota, the Senate concurring therein, that the South Dakota Legislature urges that instruction in the public schools relating to global warming include the following:

(1) That global warming is a scientific theory rather than a proven fact;
(2) That there are a variety of climatological, meteorological, astrological, thermological, cosmological, and ecological dynamics that can effect [sic] world weather phenomena and that the significance and interrelativity of these factors is largely speculative; and
(3) That the debate on global warming has subsumed political and philosophical viewpoints which have complicated and prejudiced the scientific investigation of global warming phenomena; and

BE IT FURTHER RESOLVED, that the Legislature urges that all instruction on the theory of global warming be appropriate to the age and academic development of the student and to the prevailing classroom circumstances.

High CO2 reduces roundup effectiveness http://goo.gl/652N

I encourage everyone to download and read the climate change report put out by the US Global Change Research Consortium.
http://goo.gl/652N
Here is an excerpt:

"Controlling weeds currently costs the United States
more than $11 billion a year, with the majority
spent on herbicides;241 so both herbicide use and
costs are likely to increase as temperatures and
carbon dioxide levels rise. At the same time, the
most widely used herbicide in the United States,
glyphosate (RoundUp®), loses its efficacy on weeds
grown at carbon dioxide levels that are projected
to occur in the coming decades (see photos below).
Higher concentrations of the chemical and more
frequent spraying thus will be needed, increasing
economic and environmental costs associated with
chemical use."

Too little time is the reality

Or not enough time....So how do things end up taking so much time.......
First, understand that what I am talking about is a complex system with 100's of components and 1000's of technical details, i.e. a medium size IT operation.....

The system is complex because there are dependencies among the components. The Network infrastructure is really a lot appliance computers dedicated to networking, with often remote services from outsource providers. Storage is often handled centrally by a SAN or a NAS and there are usually multiples of them at various stages of life cycle. Then there are other shared resources, authentication servers, time servers, database servers......some can be outsourced as well.

Each of these groups have multiple parts or future possibilities: speed, size, expandability, power consumption, space consumption, robustness, life cycle (depreciation) and technical compatibility with other components.

Here is an example of what I mean.
We want to expand one type of storage. This storage needs to be in a specific location because of networking constraints. That location has space but no power available. There is a set of servers in the space that are being retired and eventually replaced by servers in another location. That's where the power will come from, retiring these servers. To do that we need to schedule downtime with the users. Their next window is three weeks out. In the mean time, we realize that this server we are moving can't move because it's dependency on a local SAN storage is not moving with it. That's not moving because another server is using it that can't move in the same time frame. We now have to schedule a replace storage expansion at another location. That's going to put us beyond the first three week window, and the next window is a month away. So can we get this storage expansion (not the same storage as we started with) done before the next downtime window? And guess what? We are back to the beginning of this process, but with a whole different objective. And on it goes.....
