There are long-term cycles and short-term cycles, and then there's something new today. You see, we're well into a solar minimum (which is also a cycle) and we should be getting colder as the Sun's output falls a bit. Instead, we're getting record high global temps. The difference? All that CO2 being dumped into the atmosphere. The predicted (from the 1800s) rise from such a change is the salient fact of climate today.
And yet, man has managed to mess it up. Recently, we've gotten the bad news that the increased snowfall in Antarctica (that's also due to climate warming) is not enough to offset the melting along coastal areas.
Floridians are not going to like what happens. Up until this decade, most of the sea rise was actually thermal expansion as the oceans warmed up. That's now changing.
