Back in the wider world, regular readers will have noticed this blog rarely ventures onto the climate change topic these days. The reason for this is simple, it is not about science.
While a number of other blogs continue to expend energy on arguing with climate activists and scientists who push the alarmist narrative, pulling apart findings and assertions and countering with studies and findings from scientists who reject the alarmist creed, this blog long ago explained that such debate is a waste of time. Climate change long ago ceased to be a scientific issue, it has for a number of years been a political issue.
Several days ago this argument was bolstered by a couple of stories in the Telegraph concerning the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC) which is due to be published on Friday. Scientists are struggling to explain why global warming has slowed to a statistically meaningless level for the last 15 years, despite rising greenhouse gas emissions.
If climate change was a scientific issue the discussion about how to handle this fact, which contradicts all of the claims and projections made by climate alarmists reliant on computer models, would be exclusively between scientists. But as the Telegraph explained, other parties are actively influencing the report:
In a leaked June draft of the report’s summary from policymakers, the IPCC said the rate of warming in 1998-2012 was about half the average rate since 1951.
Several governments who fund the body have since complained about how the issue is tackled in the report.
Germany called for the reference to the slowdown to be deleted, saying a time span of 10-15 years was misleading in the context of climate change, which is measured over decades and centuries.
The US also urged the authors to include the “leading hypothesis” that the reduction in warming is linked to more heat being transferred to the deep ocean.
Belgium objected to using 1998 as a starting year for any statistics. That year was exceptionally warm, so any graph showing global temperatures starting with 1998 looks flat, because most years since have been cooler.
While Hungary worried the report would provide ammunition for sceptics.
This isn’t science, this is politics.
As such, rather than waste time countering scientific claims and trying to get one over the Michael Manns of this world, the focus should be on challenging the core of the alarmist cause – the governments and politicians who are clearly directing matter for their own ends.
In a follow up story on Saturday, the Telegraph reported that:
Jonathan Lynn, a spokesman for the IPCC, declined to comment on the content of the report because it is still to be finalised but insisted it would provide “a comprehensive picture of all the science relevant to climate change”.
More accurately, what it will provide is a picture of the ‘science’ relevant to climate change that has been shaped to fit the desired narrative of politicians, who then use the report as an excuse for more political actions to ‘fight’ climate change – which translate into more taxes, less conventional power generation, higher energy prices and more restrictions on supply. That is what needs to be challenged. Arguing statistics and method with scientists won’t make one iota of difference.
