New analysis released by Berkeley Earth

The latest Berkeley Earth study shows that the average global land temperature has risen by 2.5 degrees Fahrenheit (1.4 degrees Celsius) since 1750, including 1.5 degrees F (0.9 degrees Celsius) in the past 50 years. This closely agrees with findings from past studies by the National Oceanic and Atmospheric Administration (NOAA), NASA and others, and is rigorous enough to satisfy Richard Muller, a prominent scientist who was once skeptical that climate change was real and more so, that it is caused by humans. The good match between this new temperature record and historical carbon dioxide records suggests that the most straightforward explanation for global warming over this period is human greenhouse gas emissions.
