Climate Change and the Human Effect
Human activities, especially the burning of carbon fuels, have warmed the earth by dramatically increasing the concentrations of heat-trapping or greenhouse gases, such as carbon dioxide (CO2), in the earth’s atmosphere. The presence of greenhouse gases in our atmosphere is natural and is what makes our planet habitable by regulating temperature extremes. But as humans pump more of these gases into the atmosphere, our world’s delicate and complex climate system is being increasingly stressed.
The impacts of climate change can already be observed in many places, from rising sea levels to melting snow and ice, to changing weather patterns and increasingly violent storm systems. These effects are already affecting ecosystems, freshwater supplies, human health, agriculture yields, and physical property.
Science Behind the Facts
Scientists and climate change experts from around the globe have reached consensus that the current trajectory of rising greenhouse gas concentrations is pushing our planet’s climate into uncharted territory. Carbon dioxide levels are much higher today that at any other time in the past eight-hundred millennia. Through all those millennia, there has been a clear correlation between CO2 concentrations and global temperatures.

What Can We Do?
Although climate change may not be avoided entirely, the most severe impacts of climate change can be avoided by substantially reducing the amount of greenhouse gases released into the atmosphere. The single largest anthropogenic source of heat-trapping emissions is from the generation of electricity. Roughly 50% of the electricity generated across the United States is produced by burning coal – a dirty and polluting carbon fuel. Another 25% is produced by burning natural gas – another heat-trapping fossil fuel.
One of the easiest and most effective ways you can help our country transition away from burning polluting carbon fuels for electricity generation is by switching your home’s electricity source to clean, renewable wind power. By choosing Clean Currents, you are directly increasing demand for further domestic wind power development. Learn how Clean Currents wind power works, or:
