The failed Arctic Ocean predictions of global warming scientists

Link here. The post at the link carefully documents the endless numbers of failed doomsday predictions foisted upon us for the past decade, claiming that due to global warming the Arctic Ocean icecap would be gone by 2018.

Instead, in the past three years there is evidence that the icecap has begun to thicken and expand, recovering from a two decade decline. Though this is not a certain conclusion, what is certain is that there is no sign of the icecap vanishing, in any sense. Every prediction documented at the link, by so-called experts, is completely bogus.

There is a reason the public does not take global warming very seriously. Its advocates have cried wolf too many times. Their predictions of doom have consistently failed. Every. Single. Time.

Is the Arctic icecap now larger than in 1971?

This story compares a 1971 National Geographic map of the Arctic Ocean and its icecap with modern satellite data, and finds that the icecap is actually significantly larger now.

Take a look. Then come back to read my analysis.

Back? Okay. First, we are presently in the midst of summer in the Arctic, so the icecap shown on the modern map should shrink somewhat this year. Second, it is not clear what time of year the National Geographic map portrays. Is it maximum ice during the winter? Or they average for the year?

These questions however avoid the bigger point here, which is that there doesn’t really appear to be any significant change overall to the Arctic icecap in the past half century. The icecap had seen some major shrinkage during the first decade of the 21st century, but in recent years it has begun recovering. So much for the many past predictions by global warming activists that the Arctic will be ice free in summer because of global warming, by 2008, 2014, or 2018.

Cryosat has released its first seasonal variation map, tracking the growth of the Arctic icecap for the winter of 2010-2011.

The video at the link is quite interesting to watch. Note however that the press information says nothing about whether the icecap was larger or smaller than expected, something that probably is not surprising. It will probably take decades of further work to get the true context of these results.

Another Al Gore doomsday prediction bites the dust

In a new paper published yesterday, climate scientists described a newly discovered deep, cold current flowing off Iceland’s coast that appears to make the ocean conveyor belt that warms the northern Atlantic less sensitive to climate change than previously thought.

In other words, another one of Al Gore’s doomsday predictions has proven false.

More significantly, scientists now have no understanding why the ocean conveyor belt shut down during past ice ages, as their most favored theory now appears insufficient.

Wither the Arctic Icecap?

In a paper published today in Geophysical Research Letters, climate scientists have estimated the distribution and trends for the Arctic icecap from 1980 through March 2011. What they have found is a significant decline in older ice on top of an overall declining trend that showed a strong but partial recovery since 2008. The graph below, from the paper, illustrates clearly these trends.

What this means for the icecap itself remains unclear. As the scientists themselves note in their conclusion:
