Is global warming a global problem?

Answer: No.

The current warming trend has lasted 6000 years and seems to have (at least temporarily) ended in 1998.
To expand on this, the overall warming trend has been taking place over the last 12,000 years. The earth has historically had much higher CO2 levels and temperatures than today and has still supported vibrant life. The only global problem for humans is the hysteria that can result from people believing that what humans see to today is somehow unprecedented.

A:

Yes. Around 2008 some scientists began to warn that changes were coming on faster than the international panels had predicted. Also as predicted, only sooner, the world was beginning to suffer historically unprecedented heat waves, droughts, floods and storms. The sea level was rising while mountain glaciers, the Greenland and Antarctic ice sheets, and Arctic sea ice melted back, all at accelerating rates. Important ecosystems from alpine meadows to coral reefs were showing signs of stress. For the scientists, as Michael Oppenheimer remarked at Fordham University conference on climate change (New York, Jan. 25, 2008), "Seeing their own predictions come true has been a frightening experience."

Global warming is a global problem that requires a global solution. Nations can not expect the solution to come from other, possibly more altruistic countries, while they take a free ride.  

A:

the good news is that the Earth is in far better shape that a few were proposing and people need not live in fear.
