Climate change includes both the global warming driven by human emissions of greenhouse gases, and the resulting large-scale shifts in weather patterns. Most man-made emissions of CO2 come from burning fossil fuels. As more CO2 is released into the atmosphere, uptake of the gas by the oceans increases, causing the water to become more acidic. Climate change is the result of changes in Earth’s atmosphere (the layer of gas that surrounds Earth). China emits more CO2 than any other country. The Earth's average temperature is about 15C but has been much higher and lower in the past. These impacts extend well beyond an increase in temperature, affecting ecosystems and communities in the United States and around the world.
