Seal levels are rising, now the question is: are they rising due to an increase in temperature or something else. The sea levels cannot rise due to melting ice since ice has more volume than water (i.e it expands) hence melted ice would theoretically have less volume.
Using these datasets it is estimated that around 30% of the observed rate of rise over the satellite altimeter time period is due to ocean thermal expansion and 55% results from accumulated melting land ice. There is evidence that the land ice melt contribution has increased significantly over the past five years.

Are you saying that ice melting off of land and pouring into the oceans will not raise the sea levels? Even if iceburgs are melting, the part above the water would contribute to more water being in the oceans. Not to mention it would also contribute to the desalinization of the oceans.

Has volcanic activity been increasing?
We don't think so.
A look at the number of volcanoes active per year, over the last few centuries, shows a dramatic increase, but one that is closely related to increases in the world's human population and communication. We believe that this represents an increased reporting of eruptions, rather than increased frequency of global volcanism: more observers, in wider geographic distribution, with better communication, and broader publication.

How much ice melting in land would actually make a significant impact on global sea levels? I am curious what figure you will come up withedit on 10-7-2011 by LiveEquation because: global

Actually the ice will only displace its equivalent mass of water that it floats in.
So melting icebergs will not cause the sea levels to rise at all.
This means that we can write-off any rise in sea-levels from the Arctic ice cap if it were to melt entirely.
Antarctica however is an island so any melt run-off will cause a rise in the mean sea-level.

Actually the global warming data was manipulated to show changes in climate change. They are two different things. Global warming isn't debated but it's affect on climate change very much is.
If all the ice melts sea levels will rise between 1 and 3 meters I believe. That may not sound like much but it will be devastating to coastal regions. Those numbers may be off some as I haven't looked it up.

The first chart and the second chart are not the same. Plus they do not take into considerations volcano's on the sea floor. Overall there is increased volcanic activity despite the fact that it is not life threatening yet
Additional strong evidence that the historical increase in global volcanism is more apparent than real comes from the lower plot below. Here only the larger eruptions (generating at least 0.1 km3 of tephra, the fragmental products of explosive eruptions) are plotted. The effects of these larger events are often regional, and therefore less likely to escape documentation even in remote areas. The frequency of these events has remained impressively constant for more than a century, and contrasts strongly with the apparent increase of smaller eruptions with time.

There are any number of debatable reasons for the rising in global temps.
The growing number of sink holes is pretty easily explained though.
A large majority of sink holes are caused by damaged sewer, storm water and drinking water pipes. With the advent of modern civilisation touching nearly every corner of the globe, so have underground plumbing systems.
As they get old, they are often left in a neglected state(out of sight, out of mind) and subsequently are prone to failure.
Once the pipes start to leak they quickly erode the earth around them and eventually leave a void which in turn ends up causing a sinkhole.
