NASA chief slaps down climate sceptic senator Malcolm Roberts: 'You hold a number of misconceptions', North Queensland Register
"A senior NASA official has taken the extraordinary step of personally rejecting the claims of One Nation senator Malcolm Roberts that the agency had falsified key data to exaggerate warming in the Arctic. Gavin Schmidt, director of NASA's Goddard Institute for Space Studies, told Senator Roberts he was "mistaken" in his assertion that the US agency had "removed" Arctic data to mask warming in the 1940s."
"Thank you for your letter of the 14th November requesting information about the NASA GISTEMP analysis of global surface temperature history. Much of what you ask for is available directly from our website. Links there will lead you to the entirety of the raw data we use, all of which is public domain, along with our analysis code, which is also public. However, you appear to hold a number of misconceptions which I am happy to clarify at this time. Firstly, in the graphs you show the data is quite clearly (and correctly) labelled as originating from GHCN."
