Ice core study clarifies climate CO2 link

A new study clarifies the link between carbon dioxide and temperature increases. Ice core samples from the last glacial period were used to prove the link.

The previous Ice Age occurred between 20,000 and 10,000 years ago, and samples from that period show that temperatures rose after, not before, the melting. This points toward rising carbon dioxide levels having a direct effect on global temperatures.

Another study, called “Climate of the Past”, had similar findings, but used different methods and ice cores. Both papers pointing to the same result greatly clarifies the effects of climate warming.
