out of the ice age ... global warming

There has been no satisfactory theory presented to explain earth's ice age history. The cause of an ice age is believed to be related to several simultaneously occurring ice-age-factors, i.e. astronomical cycles, atmospheric composition, plate tectonics, and/or ocean currents. Regardless, during the peak of the current ice age, the formation of 1.9 to 2.5 mile thick ice sheets caused a global sea level drop of about 390 ft. Therefore, while we may now be experiencing short-term volatility in our weather cycles, the expectation is that as in the past the earth will warm until it is once again ice free -- and the sea level has returned to its ice free level. Thus, if our historical science is correct, we are experiencing "natural" global warming as the earth warms out of its current ice age
