Right…and starvation leads to obesity.
The alarmists at the German Potsdam Climate Institute now claim global warming leads to colder and snowier winters, which lead to accelerated ice melt in Antarctica. In their latest blog article, Dr. Sebastian Lüning and Prof. Fritz Vahrenholt say this is like claiming eating more makes you lose weight.
Ricarda Winkelmann is standing on the ice, blond hair in the wind, the German Polarstern ice-breaking research vessel is clearly visible in the background. She’s beaming because she has finally arrived on the 7th continent, which holds a multitude of secrets. Her red parka keeps her warm and protects her. Luckily there are no polar bears here, and so there is no danger to the penguins.
That’s how one could interpret the attractive photo that the Potsdam Institute for Climate Impact Research (PIK) included with its press release of 12 December 2012. The title: More ice loss through snowfall on Antarctica. This is how the fight against climate change gets a nice look, and is fresh wind for the PIK climate machinery.
Let’s look more closely at the title: “More ice loss through snowfall on Antarctica“. Now the ice in Antarctica is suppsedly melting faster than ever. The blame for this is heavier snowfall? How intersting. But that just doesn’t seem very logical. Didn’t we learn at school that glaciers grow when it snows more? And when it snows less, then they shrink. Now suddenly this is supposed to no longer apply? Very peculiar. That’s like saying global warming leads to colder winters.
Let’s look at the PIK press release:
Stronger snowfall increases future ice discharge from Antarctica. Global warming leads to more precipitation as warmer air holds more moisture – hence earlier research suggested the Antarctic ice sheet might grow under climate change. Now a study published in Nature shows that a lot of the ice gain due to increased snowfall is countered by an acceleration of ice-flow to the ocean. [...] Between 30 and 65 percent of the ice gain due to enhanced snowfall in Antarctica is countervailed by enhanced ice loss along the coastline,” says lead-author Ricarda Winkelmann.”
There’s a lot in the lines above. These mysterious claims are repeated elsewhere in other words, which we now examine.
First they explain why it is going to snow more in Antarctica in the future, namely because the air will become more humid because of the warming. That sounds plausible enough. And then a rather unusual claim pops up: Are the previous studies showing that growth of the Antarctic ice sheet suddenly wrong? This is what their unfortunate formulation suggests.
The last sentence of that part, however, finally brings clarification: “30 and 65 percent of the ice gain due to enhanced snowfall in Antarctica is countervailed by enhanced ice loss along the coastline”. Conversely, that means that 70 to 35% remains and thus causes the Antarctic ice sheet to grow. And this Antarctic sheet growth directly contradicts what the title of the study suggests: “more ice loss”.
Here we get the impression that this was poorly formulated on purpose in order to mislead the reader. This is deceptive to the highest degree. A correct title could have been, for example: “Antarctic ice sheet will continue to grow, but more slowly than previously expected.” Why wasn’t the title formulated clearly? Is the latest literature on the subject still not available in Potsdam? New ice measurements show that the Antarctic ice sheet is indeed growing (See our blog article “New ICEsat-Satellite data are in: Antarctic ice sheet has grown in mass“). Instead we read the following statement in the PIK press release, which completely misleads the layperson:
During the last decade, the Antarctic ice-sheet has lost volume at a rate comparable to that of Greenland.”
That has got to be a joke because it’s wrong from front to back.
