Technically, by some definitions, we are in a ice age. It is unusual in the history of the earth that ice exists on the poles. I heard that the current Ice Age began about 3 million years ago but this article disagrees.
quote from link below
"...
The present ice age began 40 million years ago with the growth of an ice sheet in Antarctica. It intensified during the Pleistocene (starting around 3 million years ago) with the spread of ice sheets in the Northern Hemisphere. Since then, the world has seen cycles of glaciation with ice sheets advancing and retreating on 40,000- and 100,000-year time scales. The last glacial period ended about ten thousand years ago...."

Wikipedia says,
"Glaciologically, ice age is often used to mean a period of ice sheets in the northern and southern hemispheres; by this definition we are still in an ice age (because the Greenland and Antarctic ice sheets still exist). More colloquially, when speaking of the last few million years, ice age is used to refer to colder periods with extensive ice sheets over the North American and Eurasian continents: in this sense, the last ice age ended about 10,000 years ago."
So by the Glaciologically definition we are in an ice age if there is any permanent polar ice. Even the most alarmist global warming proponents do not say that all polar ice will melt so quickly as to be all gone in your life time.

No. If we were in an ice age, the whole world would be coated in ice

Most don't think so, there seems to be a major warming trend, possibly as widespread as the entire solar system. At least one scientist has suggested as much in a worthwhile source. Take everything, even science, with a grain of salt.

(Nyuk!) Yeah. It's the one the same 'eco-scientists' predicted back in the '70s. But don't worry. It'll be over in a month or so. Ignore the quacks or they'll have you clucking in no time. They want everybody to be as scared, helpless, and panicky as they are.~~
