Notes & Quotes from the Climate Change Scene April 27, 2015

A GROUP OF SCIENTISTS spearheaded by a British fellow named Lord Lawson is launching another analysis to determine whether climate data — more specifically temperatures — have been adjusted to prove the theory of global climate change. According to an article in the UK Independent, Lawson, founder of the Global Warming Policy Foundation (GWPF) and a noted climate change denier, the study will “review the technical challenges in accurately measuring surface temperature, and will assess the extent of adjustments to the data, their integrity and whether they tend to increase or decrease the warming trend”. We’ve been down this road before, notably by the Berkeley Earth project ( ), but it apparently came to the wrong conclusion for this team. You might, however, find the conversation taking place in the messages following the article to be enlightening. (I’ve added my own two cents to the conversation this afternoon.)


BUSINESS LEADERS SUPPORT CLIMATE CHANGE POLICIES. In a largely unpublicized meeting last week, 450 representatives of hundreds of international businesses came up with a set of targets and goals to be presented at the forthcoming major meeting on climate change in Paris. According to an eyewitness report, those in attendance agreed to propose some benchmarks that went even farther than what is needed to meet the worldwide goal of keeping the temperature rise under 2C over the next 35 years. “At least in Europe, it seems that business is coming around to see that they must be part of the solution to climate change. It seems they accept the science and also see the business opportunities from acting on climate change. And they also know that they can’t wait for governments to act,” the article reported. This participation by companies who are often painted as selfish and unmotivated to help solve a problem to which they are major contributors is welcome!


A “TEMPORARY” LULL IN WARMING will not have measurable effect on long-term global climate change trends. The much-ballyhooed (by the Right) slowdown in the pace of temperature increases in the air has provided deniers a lot of largely useless ammunition in their effort to play ostrich. But a new study compares climate models that include the current slowdown to those which don’t include it and the outcomes are so similar as to be essentially the same. That’s according to a press release from the Australian ARC Centre of Excellence for Climate System Science. “This much hyped global warming slowdown is just a distraction to the task at hand,” said lead author and Chief Investigator Prof Matthew England. “This shows that the slowdown in global warming has no bearing on long-term projections – it is simply due to decadal variability. Greenhouse gases will eventually overwhelm this natural fluctuation.”
