No indication of global warming in US cornbelt region temperature data

The graph below is very consistent with what I find every time I have analyzed actual local temperature data: no indication of global warming.

“Big oil” global warming conspiracy case dismissed

“The cities’ suits against oil companies, however, do not show an industry conspiracy to suppress climate science from the public, U.S. District Judge William Alsup said, according to journalists who attended the hearing.” click here

Global warming goes on trial in California

“Global warming goes on trial at 8.00 am this Wednesday, 21 March 2018, in Court 8 on the 19th floor of the Federal Building at 450 Golden Gate Avenue, San Francisco. Court 8 is the largest of the courtrooms in the Federal District Court of Northern California. They’re clearly expecting a crowd. The 8 am start, rather than the usual 10 am, is because the judge in the case is an early bird.” click here

Global cooling means global warming is real

“Yes. How could we ever have doubted it? All this freezing weather we’ve been having is, of course, yet another sign that global warming is real. And anyway, we shouldn’t take any notice of all this white stuff that is shutting down schools, making journeys impossible, and generally freezing our asses off. Rather, we should be focusing our attention on what’s happening way to the north where no one actually lives. Apparently.” click here

Global Temperatures Continue to Drop

Global surface temperature measurements are unreliable

It is well-known that the surface temperature measurement networks have some serious problems (e.g. look here). So much so that knowledge of the historical global temperatures is inadequate to draw definitive conclusions regarding global temperature trends. The use of the term “uncertainty” here suggests that those who believe in global warming will continue to hold that belief regardless of the poor quality of the underlying data, which actually represents a lack of knowledge. They seem to have confounded the concept of uncertainty with the reality of not having knowledge.

Int. J. Climatol. 2018;1-15. DOI: 10.1002/joc.5458

There is overwhelming evidence that the climate system has warmed since the instigation of instrumental meteorological observations. The Fifth Assessment Report of the Intergovernmental Panel on Climate Change concluded that the evidence for warming was unequivocal. However, owing to imperfect measurements and ubiquitous changes in measurement networks and techniques, there remain uncertainties in many of the details of these historical changes. These uncertainties do not call into question the trend or overall magnitude of the changes in the global climate system. Rather, they act to make the picture less clear than it could be, particularly at the local scale where many decisions regarding adaptation choices will be required, both now and in the future. A set of high-quality long-term fiducial reference measurements of essential climate variables will enable future generations to make rigorous assessments of future climate change and variability, providing society with the best possible information to support future decisions. Here we propose that by implementing and maintaining a suitably stable and metrologically well-characterized global land surface climate fiducial reference measurements network, the present-day scientific community can bequeath to future generations a better set of observations. This will aid future adaptation decisions and help us to monitor and quantify the effectiveness of internationally agreed mitigation steps. This article provides the background, rationale, metrological principles, and practical considerations regarding what would be involved in such a network, and outlines the benefits which may accrue. The challenge, of course, is how to convert such a vision to a long-term sustainable capability providing the necessary well-characterized measurement series to the benefit of global science and future generations.
