Climate Change

“Our planet’s climate is influenced by many natural factors, including the Earth’s tilt, its orbit around the sun, large volcanic eruptions, and changing ocean currents. Because we know a lot about how these forces work, we also know that none of them explain the sudden, recent warming of the globe. This modern global warming is a sudden departure from the temperatures that have been typical for the past 10,000 years. Evidence shows that only increased concentrations of greenhouse gases in the atmosphere—specifically carbon dioxide concentrations—can explain Earth’s observed warming trend.”1

Human activity is the cause of climate change. Our use and combustion of fossil fuels is the cause of the increase of carbon dioxide concentrations.
