Tear fund: telling porkies?

Much as I am a fan of Tear Fund (and they've sold lots of my books), have they been caught telling porkies about climate change? They put out publicity in 2006 about a man who caught malaria in the Ethiopian Highlands because of climate change. Careful research showed that over the time they suggested, the mean temperature hadn't risen at all and the natural variability of temperature hadn't changed at all. Have a listen to this.
