Earth's Vital Signs



NASA's web page on global climate change tracks the 'vital signs of the planet'. The page shows the changes in Arctic sea ice, carbon dioxide, sea level, global temperature and the hole in the ozone layer over time. It also provides information on climate change and the role of humans.

There are also interactive guides including a "Climate Time Machine" and a "Global Warming Tube".

Follow Earth Vital Signs on Twitter.
