I'm only mildly concerned about the 'increases' in green house gases and global warming. Throughout Earth's history, there have been periods of warming and cooling - plenty of this attributable to natural acts (volcanism being the main source, meteorite impacts, etc). Certainly, the use of fossil fuels and reductions of the rain forests have led to an undetermined effect on global warming.
I am concerned more about the human race's ability to reach the point where lack of clean water and resources needed to maintain the current style of living are used up (concrete, steel, etc.). Steven Hawking preached last week that humans should concentrate on space exploration and leaving Earth before a cataclysmic disaster kills us all (either natural or through MAD weapons -bio and nuclear threats).
Seeing Venice, Italy disappear will be a sad day for us all but IMO the US will be put in a precarious place unless we cut our love of oil and improve relations with enemy nations. There's not enough resources available (steel and concrete) to 'modernize' China and India to the state were in today. Our ability to continually innovate and improve technology while becoming a service economy will continue to separate the US from the rest. It's tough knowing we're outsourcing our manual labor force - but a necessary act for long-term sustainability.
The best part about all of this is that we have the ability and ingenuity to make all these things possible (using different materials, 'creating' materials, altering fuel source usage, etc.).
