Has "Global Warming" Ended?

David Whitehouse, the BBC Science Correspondent from 1988-1998 and a Ph.D. in astrophysics, notes that global warming seems to have stalled:

The fact is that the global temperature of 2007 is statistically the same as 2006 as well as every year since 2001. Global warming has, temporarily or permanently, ceased. Temperatures across the world are not increasing as they should according to the fundamental theory behind global warming – the greenhouse effect. Something else is happening and it is vital that we find out what or else we may spend hundreds of billions of pounds needlessly.

What needs to be made explicit is that if man-made emissions were important, we should have been seeing some additional increase in temperature over the last decade.

The stationary temperature could be very significant.

In the "systems" approach to natural environments, if you change an input to a system which is in equilibrium, you can expect it to oscillate around that equilibrium before returning to it.

If you steadily increase the peturbing change, then the system can be expected to oscillate more and more wildly until the input reaches the threshold at which the system establishes a new equilibrium.

The constant temperature suggests that either the system has bedded in at its' new equilibrium, or (more likely in my amateur opinion) that the increase in CO2 is not disturbing the system.

Either way, staying stable is not what the temperatures should be doing if CO2 were a problem.

The Earth's temperature has been and continues to be primarily related to the Sun's solar output. The last 3000 years have been shown to be identically correlated with solar output. Why this fact seems to be unpublished in the media is amazing. I have read the article recently quoted here and I believe it to be true and accurate science.

I am somewhat confused. The global temp was posted and has been declared the second highest temp on record. Where are your statistics taken from. Here is one link that shows the global temperature climb over the decades including 2007.
