While we rely on them for most of our energy and will likely do so for years to come, as the Environmental Protection Agency () notes: ‘Scientists are certain that human activities are changing the composition of the atmosphere, and that increasing the concentration of greenhouse gases will change the planet’s climate. However, they are not sure by how much it will change, at what rate it will change, or what the exact effects will be.’ Despite these uncertainties it is clear that climate change is a serious problem that requires research for solutions and effective policies that allow us to meet our energy needs while protecting the environment. That’s why oil and gas companies are working to reduce their greenhouse gas emissions.
