dioxide from over 50 years ago demonstrates the multiple lines of evidence for the role of CO2 in Earth's climate system. Animations are used to describe Milankovitch cycles and the ice ages. Finally ...

find along the way. In this, the visualization also shows how far different layers of the atmosphere are and how clouds, satellites, and other flying objects differ in height. Passed initial science r ...

that provide ultra-high-resolution NASA computer models to look at how carbon dioxide in the atmosphere travels around the globe. The visualizations also illustrate differences in carbon dioxide level ...

build-up of carbon dioxide is happening because humans are putting carbon dioxide into the atmosphere faster than natural sinks can remove it. By burning fossil fuels, we have essentially taken millio ...

explanation of missing carbon is at [. A short animation that shows how carbon dioxide in the atmosphere has fluctuated over time. Comments from expert scientist: This is a very nice animation showing ...

years from EPICA (Dome D). Comments from expert scientist: This webpage offers a graph of Vostok CO2 and Antarctic surface temperature, the latter reconstructed using deuterium (a hydrogen isotope) d ...

Administration (NOAA) to learn about natural cycles and human-caused changes in our atmosphere. Links to additional data sets are provided. Comments from expert scientist: Scientific strengths: This r ...

been the largest driver of climate change over the past century. The increase of CO2 in the atmosphere has led to warming of surface temperatures over land and in the global oceans, ocean waters becom ...

cores contain climate indicators, examine the historical relationship between temperature and CO2 levels, understand that climate patterns cycle naturally, and will learn that current CO2 levels far ...

and fossil fuels have no measurable carbon-14 at all. As carbon dioxide concentrations in the atmosphere have risen over the past century or more, the ratio of carbon-13 to carbon-12 has fallen, which ...
