How exactly is the surface temperature which is insulated from the magnetic core by quite a large layer of crust changing the orientation of the earths magnetosphere? I thought that the movement of the pole was caused mostly by an increase in seismic activity over recent times (as in we've had more severe incidents which have been said to shift the pole)
http://en.wikipedia.org/wiki/North_Magnetic_Pole
It has been known ALL MY LIFE that the magnetic poles wander, and in fact have undergone complete pole reversal on average once every 450,000 years. This is not a linear process, and will experience times of acceleration and deceleration.
http://en.wikipedia.org/wiki/Geomagnetic_reversal
in fact there were articles on how the magnetic north has been shifting further and faster each year all over the place and something about runways having to repaint the north indicator on runways. (you look it up)
Anyway.. to throw some tinder onto this fire.. I've always believed that our period of climate change (bear in mind we are always in a period of climate change as climate is NOT static and its stupid to think it is) may more directly influenced by cloud formation than we are lead to believe. Hence changing the magnetic north will change the distribution of Cosmic Carged Particles and this in turn will affect local climate areas. Not to mention that since the mass adoption of Jet engines (the time scale on this matches with a lot of the accelerating climate change graphs too by the way) on aircraft we have noticed artificial coalescence of clouds by compression of the water vapour through the engine.. this causing Contrails or whathaveyou which if you watch over the course of a day (anecdotal - take with a grain of salt) seem to cascade into larger cloud formations.. this plus the location of clouds in respect to the land mass I believe needs more studying before we can make any solid claims on the trends that cause/indicate/influence global climate.. and further than that local weather.
ALSO it is very important to note that in a warmer environment that there will be increase in atmospheric CO2 as the ocean will not be able to absorb as much CO2 at higher temperatures (check out solubility of CO2 in water).

So in summary while I strongly believe most of these types of reports are funding seeking scare mongering nonsense, I do believe that we are in a state of climate change, people do have an effect, and we should all be doing our part to plan for a better future.. but please.. please.. base decision and actions on an accurate model. if the model doesnt work with more data, fix the model. Im not a denialist.. I just dont believe we have an accurate model yet.
