Summary

What if the missing heat has been there all along? In 2013, the Intergovernmental Panel on Climate Change flagged an odd phenomenon: Atmospheric temperature data collected over the past few decades suggested that global warming had slowed down beginning around 1998. Global warming skeptics crowed, and scientists delved into the global climate system to find out where the missing heat had gone. But a new analysis suggests that the real culprits are the data themselves. When better corrections for various sources of bias are applied to the data, the authors say, the so-called global warming hiatus vanishes—and in fact, they argue, global warming may have sped up.
