Via Powerline, the executive summary of this report. A few points:
1. Instrumental temperature data for the pre-satellite era (1850-1980) have been so widely, systematically, and unidirectionally tampered with that it cannot be credibly asserted there has been any significant "global warming" in the 20th century. [snip]7. Numerous peer-reviewed papers in recent years have shown the overstatement of observed longer term warming is 30-50% from heat-island contamination alone.
8. Cherry-picking of observing sites combined with interpolation to vacant data grids may make heat-island bias greater than 50% of 20th-century warming.
9. In the oceans, data are missing and uncertainties are substantial. Comprehensive coverage has only been available since 2003, and shows no warming.
10. Satellite temperature monitoring has provided an alternative to terrestrial stations in compiling the global lower-troposphere temperature record. Their findings are increasingly diverging from the station-based constructions in a manner consistent with evidence of a warm bias in the surface temperature record.
11. NOAA and NASA, along with CRU, were the driving forces behind the systematic hyping of 20th-century "global warming".
The president wants NASA to focus on global warming rather than space exploration when it's been too politicized already. The wrong direction--to more deception.
We can argue whether elements of the space program should be privatized or not, but we will still need to be able to assert ourselves and defend ourselves there--our society is built on satellite communication.
We need to get back to real scientific inquiry rather than this politicized science that has poisoned the well of the public trust.
