Carbon dioxide is everywhere: in the air, rising from cracks in the ocean floor, and in your soda can. Now it's showing up in the news! Find out why carbon dioxide is such a hot topic, and why it's going to be around for a long, long time.

 The Sun is the main source of power for the Earth's climate machine. Space-based measurements, begun in 1978, indicate Earth receives an average of 1,361 W/m<sup>2</sup> of incoming sunlight, and the amount varies by about one-tenth of a percent over the course of the 11-year solar cycle.

Human activities, mainly burning fossil fuels, are increasing the amount of carbon dioxide in our atmosphere, amplifying the natural greenhouse effect and making the pH of the ocean more acidic.

NOAA's Susan Solomon was awarded the 2009 Volvo Environment Prize for her pioneering contributions in atmospheric chemistry and physics.

The purpose of this investigation is to facilitate understanding of the basics of cloud formation involving the changing state of water. This activity should enhance the understanding of the change of state concept, which is important in the study of meteorology.

This animated video explains how the molecular structure of atmospheric gases can absorb and re-radiate infrared energy. The video uses simple models and analogies to aid in student understanding.

This image depicts a representative subset of the atmospheric processes related to aerosol lifecycles, cloud lifecycles, and aerosol-cloud-precipitation interactions that must be understood to improve future climate predictions.
