Last week, we reported on the results of the Berkeley Earth Surface Temperature (BEST) study, and they were, well, convincing. Not only did researchers confirm the accuracy of historical temperature records across the globe, it reinforced its anthropogenic origin. And, to further highlight their findings, BEST researchers compiled thousands of data sets on temperature anomalies over the course of two centuries into one alarming video of a warming world.The video above visualizes surface temperature records dating back to 1800, combining around 1.6 billion temperature reports from 15 preexisting data archives. According to BEST, one of the main objectives of unifying historical data was to "resolve current criticism of the former temperature analyses, and to prepare an open record that will allow rapid response to further criticism or suggestions."
Berkeley Earth has published their merged data set online, along with other alarming charts and graphs that highlight their findings.
Despite the sheer volume of temperature records used to make this video timeline and the complexness of BEST's undertaking to gather the data, it is perhaps one of the most succinct and alarming representations of the measurable impact of climate change over time.
