A few comments on the NetRightDaily article about climate change

An article on the website NetRightDaily makes the following assertion relevant to climate change:
“The global ice area is virtually the same today as it was in 1979.”


In support of this assertion the article links to this graph.
However, according to a study conducted by NASA, “the planet has been shedding sea ice at an average annual rate of 13,500 square miles (35,000 square kilometers) since 1979, the equivalent of losing an area of sea ice larger than the state of Maryland every year.”
The NetRightDaily article also asserts:
“[T]he satellite system, which – unlike ground monitoring stations – is not impacted by localized variants caused by development, has found that the global warming pause now stands at seventeen years.”
However, the journal Science recently published a paper which concludes that there has not been a “pause” in global warming.
Also, note that the choice of “seventeen years” is intentional. According to the above article:
“The global warming pause or hiatus narrative has often been helped by the way proponents of this idea conduct their analysis. By starting with 1998, a record hot El Niño year, the warming trend naturally appears to be smaller.”
