Carbon and Climate: an interactive discussion with scientists

El Niño: A change in wind and ocean circulation along the equator in the Pacific that impacts weather patterns around the world and disrupts the marine food web. More information
Carbon Dioxide: Measurements from the Mauna Loa observatory since 1958 and recent satellite imagery show an annual cycle plus a long-term rise in atmospheric CO2 levels. More information
Fast Carbon, Slow Carbon: A banana and a chunk of coal are examples of fast and slow carbon cycling between the air and land. More information
UV Index: The strength of ultraviolet radiation received at the surface of the Earth, or UV Index, varies by month, sun angle, clouds, air pollution and land elevation. More information
Ozone Hole: The annual thinning of the ozone layer above Antarctica is slowly improving, thanks to the Montreal Protocol that limited the use of ozone depleting chemicals. More information
Ozone Layer: A chemical made of 3 oxygen atoms, ozone in the stratosphere is important because it absorbs harmful UV radiation from the sun, protecting life on Earth. More information
Solar Radiation: Most energy on Earth comes from the Sun as radiation. Lightbulbs are used to illustrate primary wavelengths of solar radiation received: infrared, visible, UV. More information
Air Quality: We all breathe air. Monitoring Earth's air pollution from space shows how humans have a big effect on air quality and how it changes over time. More information
