Calling NASA’s Ruedy On His BS

Reader daveandrews723 got this E-Mail from Reto Ruedy at GISS

It is true that our estimates for the global mean temperature anomalies occasionally change, since we base them on the best currently available data; those do change with time as records from more stations are digitized and made available, as corrections to earlier incorrect reports are obtained, as metadata are used to account for changes in reports that have nothing to do with climate change but were caused by changes in instrumentations, reporting procedure, location of the measuring instrument etc. Finally, those estimates may change slightly as the time series get longer, which allows us to assess better how to combine records from different stations and how to bridge spatial or temporal data gaps. Sometimes those changes result in increasing trends, sometimes trends are decreased. It seems that the sources you consulted cherry-picked the former instances.

A major change that decreased the trend happened when we included ocean temperatures in addition to land based sources only, and a slight decrease was caused when we adjusted the data for urban effects. All other changes had only minor effects on the global means.

Any major changes/adjustments have always been documented on the web and in the scientific literature by the people who made them (mostly NOAA/NCDC) and so did we whenever we adopted those changes, so none of the graphs you refer to is news to us.

Maybe he isn’t aware of what his team is doing to destroy the global temperature record, but his claims don’t hold up to any scrutiny. The animation below shows NASA changes to the global surface temperature record since 1981.

These are land-only temperatures – so the ocean excuse doesn’t work. The past is always getting colder, and the slope is always increasing. The trend from 1890 to 1978 has increased by 40% since Hansen 1981.

GISS also overwrites their data as they alter it, and they try to block web crawlers to make it difficult to document their tampering.

The next graph shows the total alterations to the NASA global surface temperature record since 1981.

Perhaps he isn’t aware of what his group at GISS is doing to destroy the integrity of the surface temperature record. His comments above would seem to indicate that.

60 Years Of No Major Hurricanes In New England

This week in 1954, Boston’s Old North Church was damaged by hurricane Carol.

Another major (category 3-5) hurricane hit New England ten days later. There have been no major hurricanes in New England since.

Get The Shovels Out

At the end of another long hot summer in Greenland, the research station in the center of the ice cap is nearly buried in new snow which accumulated over the summer

Climate experts tell the press that Greenland is melting down, even though their own data shows a net surface gain of 300 billion tons of ice over the past year, and that more than 90% of the surface has gained ice.

Arctic Shipping Update

Climate experts say that Northeast and Northwest Passages are open for business, but neither will open up this year.

Self-Fulfilling Prophesy From Gavin Schmidt

In 1998, Gavin warned us that climate data sets will be “distorted and twisted beyond all usefulness”

Eos, Vol. 79, No. 28, July 14, 1998

Unless we are vigilant, “data sets” will evolve and data that have been so painstakingly collected and saved will be distorted and twisted beyond all usefulness. Our care in using data should be a force analogous to natural selection, keeping data sets fit for the purposes intended. If we do not take care, the gold standards of climatology may in time turn to lead.

—Gavin Schmidt, NASA Goddard
Institute for Space Studies, NY., USA;
E-mail: gschmidt@giss.

All that is labeled data is not gold – Schmidt – 2006 – Eos, Transactions American Geophysical Union – Wiley Online Library

And that is exactly what he did. The animation below shows how Gavin has altered the US temperature record since 1998, and turned the gold standards of climatology into lead

Shock News : BOM Is Tampering With Climate Data

ScreenHunter_2207 Aug. 22 23.18

THE Bureau of Meteorology has been accused of manipulating historic temperature records to fit a predetermined view of global warming.
Researcher Jennifer Marohasy claims the adjusted records resemble “propaganda” rather than science.

Dr Marohasy has analysed the raw data from dozens of locations across Australia and matched it against the new data used by BOM showing that temperatures were progressively warming.

In many cases, Dr Marohasy said, temperature trends had changed from slight cooling to dramatic warming over 100 years.
