Global temperature records are built from thousands of measurements taken on land, at sea and from satellites. This short explainer from NASA Goddard shows how those numbers are collected, checked and combined into a single record.
Scientists say the strength of the record comes from using several independent sources that point the same way, rather than relying on any one instrument.
Press play for a clear, jargon-free walk through the method, then read our environment coverage for what the data means locally.
Great reporting. This is the clearest summary of the story I have read so far.
Good question. We will update the article as soon as there is word.
Interesting angle. Does anyone know if there is an official statement yet?
Thanks for reading and for the feedback!
