Climate Change Data: Change in Atmospheric CO2 levels - Carbon Dioxide

Climate Change Studies, Reports and Data:Increasing Atmospheric Carbon Dioxide (CO2)

change in atmosphere CO2levels, graphSo, you've heard the atmospheric levels of carbon dioxide are rising; CO2 is one of thegreenhouse gases. According to NASA, this graph, based on the comparison of atmospheric samples contained in ice cores and more recent direct measurements, provides evidence that atmospheric CO2 has increased since the Industrial Revolution.

  Nasa, Graph of Atmosphereic carbon, The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. The current warming trend is of particular significance because most of it is very likely human-induced and proceeding at a rate that is unprecedented in the past 1,300 years.1
