Carbon dioxide in the earth’s atmosphere is at a level that is unprecedented in human experience. University of Dayton professor Bob Brecha explains how we know that we are responsible for the excess CO2.

Carbon dioxide, or CO2 is an important natural part of our atmosphere. Right now, CO2 levels are increasing rapidly. How much of this is part of a natural cycle or is it due to humans?  Scientists know how to answer this question.

Survey Of Dayton Residents Finds Climate Change Concerns

Thanks to an unusually warm spring followed by a hot summer, Cleveland and Columbus both had their highest average annual temperatures this past year. Both cities broke records set in 1998.

Dayton and Cincinnati fell short of breaking their records. But it was still among the five hottest years those cities have posted.

State climatologist Jeffrey Rogers says more and more evidence points to climate change for the spiking temperatures and he says warmer temperatures in Ohio mean more rain

Climate, Human Population and Human Survival: What the Deep Past Tells Us about the Future

The melting of glaciers due to global warming is threatening fresh water supplies to human populations in a number of regions. Shown here: Canada's Athabasca Glacier.

The controversies generated by climate science in recent years center around the human relationship with the natural world and with natural resources. This month, historian John Brooke puts that critical question in historical perspective—deep historical perspective. For most of human history, our species had to struggle to survive powerful natural forces, like climate and disease. In the past three centuries, however, things have changed dramatically: that struggle has been reshaped by the unprecedented growth of the human population—from under one billion to now over seven.
