Tide gauge data tampering in Australia?

“Within Australian universities, from Murry Shelby to Bob Carter, from Peter Ridd to myself, academics not supporting the narrative are simply forced to leave, in a way or another, or not even start, as Bjorn Lomborg. I do not believe anyone within Australian universities will declare that the sea levels in Fremantle have been rising since 1897 without any significant acceleration component, and in the next 8 years they may rise on average of not even 25 millimetres, but  16 millimetres  …..” click here

Is the ‘climate change’ policy political movement over?

“Climate change is over. No, I’m not saying the climate will not change in the future, or that human influence on the climate is negligible. I mean simply that climate change is no longer a pre-eminent policy issue. All that remains is boilerplate rhetoric from the political class, frivolous nuisance lawsuits, and bureaucratic mandates on behalf of special-interest renewable-energy rent seekers.” click here

‘Climate science’ in its current state is not self-correcting

“Many problems plagued climatology since climate science took over in the 1980s. Each specialist in a different area suddenly became an expert in climate and climate change. They brought their different perspectives, sometimes helpful, but usually unhelpful and even distorting. Most came for funding opportunities, but many for the political objectives. They all lack awareness that climatology is a generalist discipline. It involves putting together, in a systems approach manner, all the studies from specialists who, because they get involved in climate studies, call themselves climate scientists. This piecemeal approach reflects the problems of creating computer climate models. Modellers assemble as many facts as they think apply, or will achieve their result and then, with improper or inadequate connecting mechanisms, put together what they think represents global climate.” click here

Urbanization impacts China surface temperature trends

Most estimates of Chinese regional Surface Air Temperatures since the late-19th century have identified two relatively warm periods – 1920s–40s and 1990s–present. However, there is considerable debate over how the two periods compare to each other. Some argue the current warm period is much warmer than the earlier warm period. Others argue the earlier warm period was comparable to the present. In this collaborative paper, including authors from both camps, the reasons for this ongoing debate are discussed. Several different estimates of Chinese temperature trends, both new and previously published, are considered. A study of the effects of urbanization bias on Chinese temperature trends was carried out using the new updated version of the Global Historical Climatology Network (GHCN) – version 4 (currently in beta production). It is shown that there are relatively few rural stations with long records, but urbanization bias artificially makes the early warm period seem colder and the recent warm period seem warmer. However, current homogenization approaches (which attempt to reduce non-climatic biases) also tend to have similar effects, making it unclear whether reducing or increasing the relative warmth of each period is most appropriate. A sample of 17 Chinese temperature proxy series (12 regional and 5 national) is compared and contrasted specifically for the period since the 19th century. Most proxy series imply a warm early-20th century period and a warm recent period, but the relative warmth of these two periods differs between proxies. Also, with some proxies, one or other of the warm periods is absent.

Climate sensitivity, global warming potential calculations distorted by small denominators

“At this point, it is crucial to observe that every other gas is compared to CO2 to determine its GWP value. In other words, whatever GWP value is determined for CO2, that value is re-set equal to 1, so that the calculation of GWP for a gas produces a number compared to CO2. The slope of the absorption curve for CO2 becomes the denominator of the calculation to find the GWP of every other gas.” click here

Climate change will help U.S. corn production

“Contrary to previous analyses, research published by Michigan State University shows that projected changes in temperature and humidity will not lead to greater water use in corn. This means that while changes in temperatures and humidity trend as they have in the past 50 years, crop yields can not only survive – but thrive.” click here

Climate changes are driven primarily by the sun

“Hailed as ‘the last piece of the puzzle’ in codifying our understanding of the mechanism(s) that cause climate changes, scientists are increasingly turning to Sun-modulated cosmic ray flux and cloud cover variations as the explanation for decadal- and centennial-scale global warming and cooling. In other words, climate changes are increasingly being attributed to natural variability, not anthropogenic activity. “ click here
