Sorry to be repetitive but it’s a new week and surprise, there’s another dirty big blowie discovered in the IPCC’s reports.
One of the many dire forecasts from the panel was that by 2020 global warming would shrink African agricultural production by 50 per cent.
Er, not so.
The origin of this claim was a report written for a Canadian advocacy group by Ali Agoumi, a Moroccan academic who draws part of his current income from advising on how to make applications for “carbon credits”. As his primary sources he cited reports for three North African governments. But none of these remotely supported what he wrote. The nearest any got to providing evidence for his claim was one for the Moroccan government, which said that in serious drought years, cereal yields might be reduced by 50 per cent. The report for the Algerian government, on the other hand, predicted that, on current projections, “agricultural production will more than double by 2020″. Yet it was Agoumi’s claim that climate change could cut yields by 50 per cent that was headlined in the IPCC’s Working Group II report in 2007.
UPDATE:
This has long been suspected. Now it’s been scientifically verified.
“We concluded, with overwhelming statistical significance, that the IPCC’s climate data are contaminated with surface effects from industrialisation and data quality problems. These add up to a large warming bias,” he said.
Straw and camel’s back, anyone?
