Northern Sea Ice Expanding

Forbes has an article describing the latest NASA findings concerning satellite monitoring of Arctic sea ice. The article notes that when the system was deployed in 1979, the Arctic was just coming out of a cooler period. Nevertheless, the sea ice measurements for 1979 were used as the "base line" for all subsequent measurements. Thus, in the warmer 1980's and 1990's, the sea ice retreated to a certain extent. But now that we have been in a cooling trend, the sea ice once again expanded. It is now 5% more than in 1979.

In a related topic, The Daily Caller reports:
Weather agencies in Australia, Paraguay and Switzerland may be manipulating temperature data to create a sharper warming trend than is present in the raw data — a practice that has come under scrutiny in recent months.

Most recently, Dr. H. Sterling Burnett with the Heartland Institute detailed how the Swiss Meteorological Service adjusted its climate data “to show greater warming than actually measured by its temperature instruments.”

In his latest article, Sterling wrote that Switzerland’s weather bureau adjusted its raw temperature data so that “the temperatures reported were consistently higher than those actually recorded.” For example, the cities of Sion and Zurich saw “a doubling of the temperature trend” after such adjustments were made.
The article goes on to describe similar shenanigans discovered to have been perpetrated by weather agencies in Paraguay and Australia.
