We are descendents of the ice age.

We are descendents of the ice age. Periods of glaciation have spanned the whole of
human existence for the past 2 million years. The rapid melting of the continental glaciers at
the end of the last ice age spurred one of the most dramatic climate changes in the history of
the planet. During this interglacial time, people were caught up in a cataclysm of human
accomplishment, including the development of agriculture and animal husbandry. Over the
past few thousand years, the Earth’s climate has been extraordinarily beneficial, and humans
have prospered exceedingly well under a benign atmosphere.
Ice ages have dramatically affected life on Earth almost from the very beginning. It is
even possible that life itself significantly changed the climate. All living organisms pull
carbon dioxide out of the atmosphere and eventually store it in sedimentary rocks within the
Earth’s crust. If too much carbon dioxide is lost, too much heat escapes out into the
atmosphere. This can cause the Earth to cool enough for glacial ice to spread across the land.
In general the reduction of the level of carbon dioxide in the atmosphere has been
equalized by the input of carbon dioxide from such events as volcanic eruptions. Man,
however, is upsetting the equation by burning fossil fuels and destroying tropical rain forests,
both of which release stored carbon dioxide. This energizes the greenhouse effect and causes
the Earth to warm. If the warming is significant enough, the polar ice caps eventually melt.
The polar ice caps drive the atmospheric and oceanic circulation systems. Should the
ice caps melt, warm tropical waters could circle the globe and make this a very warm,
inhospitable planet.
Over the past century, the global sea level has apparently risen upwards of 6 inches,
mainly because of the melting of glacial ice. If present warming trends continue, the seas
could rise as much as 6 feet by the next century. This could flood coastal cities and fertile
river deltas, where half the human population lives. Delicate wetlands, where many marine
species breed, also would be reclaimed by the sea. In addition, more frequent and severe
storms would batter coastal areas, adding to the disaster of the higher seas.
The continued melting of the great ice sheets in polar regions could cause massive
amounts of ice to crash into the ocean. This would further raise the sea level and release more
ice, which could more than double the area of sea ice and increase correspondingly the
amount of sunlight reflected back into space. The cycle would then be complete as this could
cause global temperatures to drop enough to initiate another ice age.
