Europe's freeze further proof of global warming!


by Peter Westmore

News Weekly, March 24, 2018

For weeks, Europe and North America have been in the grip of an icy freeze that has caused snow to fall as far south as Greece and southern Italy, and across much of the United States. Such events are not unknown, but usually happen earlier than March, the beginning of spring.

But for climate alarmists, the explanation has to be that the freezing cold – like hot weather – is proof of global warming, aka “climate change”.

Their explanation is ingenious. They claim that warm air at the North Pole has displaced cold air southward, and the North Pole is “hot”.

For example: “Just how hot is the Arctic now?” tweeted Peter Gleick, president emeritus of the Pacific Institute and a member of the U.S. National Academy of Science. “Hotter than ever measured in winter. Human-caused climate change is beginning to radically transform our planet.”

The question is: who is Peter Gleick?

An internet search reveals that he has no special knowledge of climate science, but rather claims expertise in water policy. In relation to environmental issues, he is a climate extremist. His website quotes him as saying in 1989: “Among all the major environmental threats, global climatic change appears to be the most likely to affect international politics because of its wide scope and magnitude.”

Freezing cold

The facts, however, contradict this. Temperatures in the Arctic are freezing cold. The clearest indicator of this is to be found in the published Arctic Sea Ice data, which is freely available online.

Arctic Sea Ice extent is an indicator of the area where temperatures are below freezing. The latest images show that the Arctic Sea Ice extent is above 15 million square kilometres, about the same as seen at this time in recent years, and a little lower than the average Sea Ice extent for the period 1980–2000.

The image shows that every year, sea ice varies between a minimum of about 6 million sq km in September, and a maximum of 15-17 million sq km in March.

Looking at global temperatures, satellites have been monitoring global temperatures since about 1980.

The figures for these are published monthly by one of America’s leading meteorologists, Dr Roy Spencer. Before becoming a principal research scientist at the University of Alabama in Huntsville (UAH) in 2001, he was a senior scientist for Climate Studies at NASA’s Marshall Space Flight Center, where he and Dr John Christy received NASA’s Exceptional Scientific Achievement Medal for their global temperature monitoring work with satellites. He still works for NASA.

On his website, Dr Spencer charts the satellite data showing average global temperatures, as analysed at the University of Alabama, Huntsville Campus.

The latest figures show that average temperatures in the lower troposphere (at the earth’s surface) is about 0.2 degrees Celsius above the average for the 30 years from 1981 to 2010. The peaks in this data occur at times of El Niño, the global temperature peak that is often associated with droughts in Australia.

Current global average temperatures, according to Dr Spencer, are lower than they were at the time of the 1996 and 2016 El Niños.

These observations radically differ from the scenarios published by the Intergovernmental Panel on Climate Change (IPCC), which has predicted a 2-degree Celsius rise in temperatures in this century alone.

In light of the freezing weather recently observed in the northern hemisphere, it will be interesting to watch how future temperatures vary from the long-term averages. Over recent months, the temperature trend according to the UAH data is downward.

Rising sea levels?

Another widely publicised claim is that sea levels are rising at unprecedented speeds, and that sea levels will rise by metres by the end of the century.

These are often accompanied by apparently alarming pictures or videos of icebergs breaking off from the ice shelves of Antarctica and Greenland. In fact, as the ice shelves are already floating on water, and represent rivers of ice flowing down to the sea, these are entirely natural events that have occurred since time immemorial.

Historically, icebergs have been seen off the coast of New Zealand, although none have been seen recently, and the sinking of the Titanic over a century ago was due to an iceberg that had broken away from somewhere near Greenland months or years earlier.
