The document discusses evidence that the global climate is getting warmer. It provides temperature data from instruments over the past 200 years showing a slight warming trend. Proxy climate records using factors like tree rings, ice cores, lake sediments and coral growth extend the temperature record back thousands of years. When these multiple proxy records from around the world are combined, they indicate that the 0.6°C surface warming over the past 100 years is unprecedented over the past 2000 years and the recent warming therefore appears to be significant.
