The world has warmed more slowly than had been predicted by computer models, which were “on the hot side” and overstated the impact of emissions on average temperature, research has found. Michael Grubb, the professor of international energy and climate change at University College London and one of the study’s authors, admitted that his previous prediction had been wrong. He stated during the climate summit in Paris in December 2015: “All the evidence from the past 15 years leads me to conclude that actually delivering 1.5°C is simply incompatible with democracy.” Speaking to The Times, he said: “When the facts change, I change my mind, as Keynes said.” —Ben Webster, The Times, 19 September 2017
To have the discrepancy between climate model predictions and reality acknowledged in Nature Geoscience is good. It has already resulted in a substantial debate about this most fundamental approach to assessing the impact of man-made climate change, demonstrating once again that ‘the science’ is definitely not settled. Assumptions made about important details of climate science that were accepted a decade ago are becoming increasingly frayed. Let us hope that a new era of scientific reality will replace the far-to-simple messages previously proclaimed to the public. – David Whitehouse, GWPF Observatory, 19 September 2017
A report published 3 years ago by the Global Warming Policy Foundation showed that the best observational evidence indicates our climate is considerably less sensitive to greenhouse gases than climate models are estimating. “The observational evidence strongly suggests that climate models display too much sensitivity to carbon dioxide concentrations and in almost all cases exaggerate the likely path of global warming,” says Nic Lewis. —Global Warming Policy Forum, 18 September 2017
Gary D. Cohn, the top White House economic adviser, told ministers from several major allies on Monday that the Trump administration was “unambiguous” about its plans to withdraw from the Paris agreement on climate change unless new terms were met. President Trump announced in a Rose Garden speech in June that the Paris agreement — under which nearly 200 nations pledged voluntary targets to cut planet-warming greenhouse gas emissions and to support poor countries grappling with rising global temperatures — was bad for America’s economy. He said the United States would withdraw from the agreement but left open the possibility that he might try to “renegotiate” the accord. —The New York Times, 18 September 2017
The BBC has reprimanded the presenter of Radio 4’s Inside Science after he called on his Twitter followers to write to their local MPs about the reappointment of Graham Stringer, a climate change skeptic, to a parliamentary committee. —Graham Ruddick, The Guardian, 18 September 2017
