How long has global warming effected the earth?
Approximately 4 billion years, give or take a few million years. Since the beginning, the earth has gone through continuous warming and cooling periods. For instance, about 200 million years ago dinsoaurs were roaming around the jungles of Colorado. Global cooling might have been their downfall. More recently, glaciers covered most of Wisconsin about 700,000 years or so ago. Since then there have been as many as 10-12 glacial advances and retreats. The most recent major glacial advance peaked out about 20,000 years ago, then global warming set in and glaciers retreated for about 10,000 years after which there was a slight glacial advance. The earth warmed again and peaked around 5,000 years ago. The warming period since the last major glacial advance was when man started developing agriculture, and have more time to invent stuff. About 2000 years ago there was a minor glacial advance in some areas, then warming. About 500-600 years ago the "little ice age" began with cooling temps that lasted to the mid 1800's. Since then it has been warming except for a cool down from about 1940-1970 when some scientists thought we were going into another "ice age". Since the mid 70's things have been warming rapidly. This warming has been a great opportunity for some folks to blame all global warming on human activities. So far I don't think anyone really knows for sure, but whatever the cause, it could have profound effects on all life on earth, just as it always has.
Was there an ice age around 1600BC?
We are in an Ice Age now, although in an inter-glacial period when most ide has retreated for a time. The current Ice Age began more than a million years ago. The most recent glacial period ended about 10000 years ago, so about 8000 BC.
The most recent ice age ended how many years ago?
The last glacial period is sometimes colloquially referred to as the 'last ice age'. But the use of 'ice age' is incorrect. Glacials, on the other hand, refer to colder phases within an ice age that separate interglacials. The end of the last glacial period is not the end of the last ice age. The end of the last glacial period was about 10,500 BCE, while the end of the last ice age has not yet come.
How are growth rings and ice cores useful in determining the ages of geologic events?
Geologists have learned to use growth rings in shells, as well as rhythmic layering in sediments and in glacial ice, to date events numerically back through recent Earth history.
When did the most recent ice age begin and end?
Strictly speaking the most recent Ice Age started about 2.6 million years ago and we are now in an interglacial period,(warm period), during the Ice Age. The last glacial period started 115,000 years ago and finished about 10,000 years ago, though there were a number of warmer periods during that time.

The San Juan Islands are a glacial feature left over?
Yes and no. A lot of the material that forms the San Juan islands are leftovers from glacial action. Material abundant on the islands that the glaciers brought includes most of the sand and gravel as well as 'erratic' boulders. Earlier features were also shaped and changed by the glaciers, but there are indeed rock formations in the San Juans that predate the Pleistocene (the most recent 20 or so glacial advances) glaciations. An interesting way to think about glacial effects (bringing material and changing the shapes and surface formations of material that was already present) to consider the southward advance and northward retreat of the glaciers.
