Micheal Mann and Snopes both did hit pieces on me this week. I must be making them nervous. Here is the Snopes article.
Since 2014, climate-change deniers have squeezed millions of views, Facebook shares, and Twitter retweets by retelling a story alleging the discovery of “faked” NASA data designed to “fit a climate change narrative.” Though copied almost wholesale from a blog post
The blog post was one I made in 2o12. But instead of pointing to my web site, they linked to an archived version – most likely to keep people from visiting my blog. It included this animation, showing NASA data tampering.
They go on :
The “smoking gun” concerns a climate record known as the NASA Goddard Institute for Space Studies Surface Temperature Analysis (GISTEMP). These records are based on a massive global dataset of temperature stations from around the world, combining several collections of data originally collected by individual weather stations. The record provides “a measure of the changing global surface temperature with monthly resolution for the period since 1880, when a reasonably global distribution of meteorological stations was established.”
This is what Snopes describes as a “reasonably global distribution of meteorological stations” The map shows where GHCN has daily temperature data from 1890.
Then they went to their go-to man, Zeke Hausfather, who told them :
All told, the most significant effect of all these changes came from the time-of-day adjustments. Collectively, the adjustments served to produce a slightly increased warming trend in the United States record compared to the earlier records.
This is complete nonsense. TOBS (time of day) is about one third of the total adjustment, and goes the opposite direction of the massive upwards adjustments since the year 2005.
Snopes made no attempt to contact me. Had they done that they would have known that essentially all of the adjustments since 1990 are due to fake data.
In the 1999 paper where I got the NASA temperature graph, Hansen complained that the US is cooling.
Yet in the U.S. there has been little temperature change in the past 50 years, the time of rapidly increasing greenhouse gases — in fact, there was a slight cooling throughout much of the country.
Snopes described this switch from cooling to rapid warming as :
Collectively, the adjustments served to produce a slightly increased warming trend in the United States record compared to the earlier records.
This is what they call a “slightly increased warming trend.”
Climate journalism is a complete shambles, and has nothing to do with actual journalism.
