MSNBC reports that a scientific paper published in the peer-reviewed journal Nature on Wednesday concluded that during the end of the last Ice Age (12,000 years ago), global temperatures rose after carbon dioxide levels started to rise.  This provides even more scientific evidence that there is a connection between warming temperatures and rising carbon dioxide.

For this study, which was funded by the National Science Foundation, researchers reconstructed temperature records from ice and soil cores at 79 sites around the world from around the same time period.

Earlier studies postulated that changes in Earth’s orbit may have triggered the warming trend by causing ice sheets to melt, but the new study suggests CO2 played a more important role.
