evidence: Petitioners identify several instances of allegedly flawed data adjustments at specific weather stations, citing the records of some individual stations that they claim show inappropriate manipulation. The Coalition for Responsible Regulation references a non-peer-reviewed analysis by Eschenbach (2009) as a basis for claiming: ‘For example, adjustments made by the Global Historical Climatology Network (GHCN) in Darwin, Australia, transformed a temperature trend falling at 0.7°C per century to one that was warming 1.2°C per century.’ [...] The study’s authors make no claim that global warming science is ‘unsettled.’ In fact, they introduce the study with the following statement: ‘Over the past century, global average surface temperatures have warmed by about 0.75°C. Much of the warming occurred in the past half-century, over which the average decadal rate of change was about 0.13°C, largely due to anthropogenic increases in well-mixed greenhouse gases.’
