You gotta read beyond the headline to see their bullshit. It’s all based on a model. tRUsT tHE sCiEnCe!

Tuesday’s global average temperature was calculated by a model that uses data from weather stations, ships, ocean buoys and satellites, Paulo Ceppi, a climate scientist at London’s Grantham Institute, explained in an email Wednesday. This modeling system has been used to estimate daily average temperatures starting in 1979.

“This is our ‘best guess’ of what the surface temperature at each point on earth was yesterday,” he said.

Instrument-based global temperature records go back to the mid-19th century, but for temperatures before that, scientists are dependent on proxy data captured through evidence left in tree rings and ice cores. “These data tell us that it hasn’t been this warm since at least 125,000 years ago, which was the previous interglacial,” Ceppi said, referring to a period of unusual warmth between two ice ages.
