Going Underwater, But Who Is To Blame?

Of course, the cause is "climate change." This phrase has come to automatically mean an implication of mankind and industrialization. Yes, climate changes. Sea levels have been rising for 10,000 years. Why blame man? They were rising faster in the previous decade than they are in this one!

...sea level is certainly rising – of course, it has been rising for the past 10,000 years. During the last glacial period, sea level dropped 400 feet as water was tied up in ice, and as we have moved out of the cold glacial period, sea level has recovered. The question for climate change experts is not “Is sea level rising” but rather “Is sea level rise accelerating?” In 2001, the Intergovernmental Panel on Climate Change (IPCC) wrote “No significant acceleration in the rate of sea level rise during the 20th century has been detected”, while in 2007, IPCC wrote “Global average sea level rose at an average rate of 1.8 [1.3 to 2.3] mm per year over 1961 to 2003. The rate was faster over 1993 to 2003: about 3.1 [2.4 to 3.8] mm per year. Whether the faster rate for 1993 to 2003 reflects decadal variability or an increase in the longer-term trend is unclear.” To say the least, the IPCC has been very cautious on the issue of accelerated sea level rise.
