Dedicated to the balanced discussion of global warming
This is the third of a 5 part series reviewing the comments of the Science and Public Policy Institute (SPPI) in regards to “An Inconvenient Truth” (AIT).
ERROR 18 – I can’t find evidence for SPPI’s statement that the Arctic has
increased decreased in temperature 1 deg C in the last 60 years. SPPI falls victim here to the common Gore affliction of pointing out individual instances of information (ice bound ships) and assuming that this is conclusive data. I have called AIT out on this and I need to do the same with SPPI. Unless they can point to a reference for the temperature increase, I need to call this one spin.
ERROR 19 – Sorry, SPPI, this one is spin. NASA mapped the ice and it is adding in some places and subtracting in others but the balance is going down.
ERROR 20 – This one is tough. Gore definitely screws up saying that 40% of the world’s population gets their water from glacial melt. This isn’t true. I can’t find any evidence that snow melt is not decreasing as SPPI claims but since we are judging AIT, we have to give this one to SPPI.
ERROR 21 – There is no question that the glaciers in Peru are receding but as I wrote on this site before, the argument that it is caused by human caused global warming is very tenuous.
ERROR 22 – There is no question that glaciers have been shrinking for some time. Saying that this is caused by humans is very tenuous.
ERROR 23 – Gore definitely takes advantage of human suffering in the film and blames the Sahara on human caused global warming. He makes a poor argument here and this is where he also talks about Lake Chad so in essence this error is the same as 6. This is an example of double dipping so we can’t really say that SPPI was correct in both instances.
ERROR 24 – SPPI has definitely tried to spin this one. Gore was specifically talking about the Larsen ice shelf and it absolutely did recede dramatically in a short amount of time. Yes, much of Antarctica is getting colder but Gore’s facts were correct.
ERROR 25 – I cannot find evidence of where Mr. Gore says that half a dozen ice shelves the size of Rhode Island have broken up. Since I can’t find where it was said, I can’t say that AIT is wrong. I have to mark this as spin for SPPI. I am relying on the unofficial transcripts on this as I don’t want to watch the entire movie again just to find this reference.
ERROR 26 – There is no doubt that the ice shelf at Larsen was larger in history. There is also no doubt that it has changed shape dramatically over the years. I have to give this one to SPPI not because of what they said but because the shelf was so large in 1995. Global warming didn’t just start happening in the last 12 years so I have to call Mr. Gore on this reference since he is blaming global warming on the entire phenomenon. Rather, many scientists attribute this change to Arctic Oscillation and Mr. Gore doesn’t bother to mention this as a possibility.
