There has been an unending stream of media reports about how the last few years have been the warmest on record.
They gloss over that they are only referring to the last 150 years, because temperatures have been higher than today on several occasions over the past 10,000 years, a period between glaciations know as the Holocene.
Recently, a presentation by Tony Heller caught my attention, in which he had facts, coupled with evidence, that shed light on the media’s hypocrisy.
What follows uses some of the materials from Mr. Heller’s presentation, coupled with additional information. (Relevant links are itemized below.)
The first chart is Figure 3, from Dr. Roy Spencer’s evaluation of the heat island effect.
It shows that the urban heat island effect has skewed reported temperatures higher than where population density is low. Areas with low population density are representative of the vast majority of land surface areas.
Heller points out that temperatures in the 1930s were higher than today. He uses the 1930 and 1936 Olympics to highlight this fact.
Lake Placid, 1932 Olympics:
And Garmisch-Partenkirchen, 1936 Olympics:
Heller also used the next chart from Real Climate Science. It shows that the temperatures, as supported by the above news articles, were higher in the 1930s than today.
Nearly every year over the past decade, the media, including the Associated Press (AP) and Reuters, have published stories about the current year’s temperature being the highest on record.
Americans have been fed misinformation, including from our governmental agencies, including NASA and NOAA. Here’s the headline from NASA’s website:
“NASA, NOAA Analyses Reveal 2019 Second Warmest Year on Record”
BUT the headline is wrong:
Today’s temperatures are not the highest, or second highest, on record: Not for the past one-hundred-fifty years, or for the past 10,000 years.
