Roger Andrews addresses seven claims of the IPCC Working Group 2. I know that oil people are supposed to be automatically suspect, but open your mind and read what Andrews has to say as he handily addresses these points…
Claim 1: Glaciers continue to shrink almost worldwide due to climate change
Claim 2: Many terrestrial, freshwater, and marine species have shifted their geographic ranges ….. in response to ongoing climate change.
Claim 3: While only a few recent species extinctions have been attributed as yet to climate change, natural global climate change at rates slower than current anthropogenic climate change caused significant ecosystem shifts and species extinctions during the past millions of years.
Claim 4: Based on many studies covering a wide range of regions and crops, negative impacts of climate change on crop yields have been more common than positive impacts.
Claim 5: Impacts from recent climate-related extremes, such as heat waves, droughts, floods, cyclones, and wildfires, reveal significant vulnerability and exposure of some ecosystems and many human systems to current climate variability.
Claim 6: At present the worldwide burden of human ill-health from climate change is relatively small … and is not well quantified. However, there has been increased heat-related mortality and decreased cold-related mortality in some regions as a result of warming.
Claim 7: Violent conflict increases vulnerability to climate change.
