Will More Earthquakes Result From Global Warming?

Along with global warming there are some changes expected in vegetation, water levels, temperatures in various climatic zones and, I hypothesise, possibly even more earthquakes.

My reasons are as follows:
As the surface of the earth heats up the water heats up and expands and so rises. The melting of ice that rests on land mass also contributes to the rise in water levels and so one might wonder whether the slight weight redistribution of water (coming further op onto land and less mass of ice on land where ice is melting) would effect movement of tectonic plates.

It was reported in New Scientist (5 May 2007) that South Asia’s monsoons dump so much rain on the Himalayas that the sheer weight appears to suppress seismic activity along the mountain range. Another theory is that the rains trickle down through fissures in the rock and possibly lubricate tectonic plates.

If that is the case, why should we not experience a change in tremor activity on earth because of redistribution of water, which causes a greater area of the surface of the earth to be covered and, possibly more importantly, because when the earths surface gets hotter it should expand (generally heating causes expansion)?
If tectonic plates expand it seems obvious that tremors could result.
