Trends in global warming
After September of this year, the Earth will be entering its 22nd year without statistically significant warming trend, according to satellite-derived temperature data.
Since September 1994, University of Alabama in Huntsville’s satellite temperature data has shown no statistically significant global warming trend. For over 20 years there’s been no warming trend apparent in the satellite records and will soon be entering into year 22 with no warming trend apparent in satellite data — which examines the lowest few miles of the Earth’s atmosphere.
Satellite data from the Remote Sensing Systems (RSS) group also shows a prolonged “hiatus” in global warming. After November of this year, RSS data will be in its 22nd year without warming. Ironically, the so-called “hiatus” in warming started when then vice President Al Gore and environmental groups touted RSS satellite data as evidence a slight warming trend since 1979.
For years, climate scientists have been debating the “hiatus” in global warming, pushing dozens of explanations for why global temperatures had not risen significantly in the last decade or so in the surface record and for the last two decades in the satellite record. but the debate was cut short in June when the National Oceanic and Atmospheric Administration .
The study was highly criticized for inflating the temperature record since the late 1990s to show vastly more global warming than was shown in older data. The warming “hiatus” was eliminated and the warming trend over the period was more than doubled.
“There’s been so much criticism of NOAA’s alteration of the sea surface temperature that we are really just going to have to use the University of East Anglia data, ” Pat Michaels, a climate scientist with the libertarian Cato Institute, told The Daily Caller News Foundation.
“I don’t think that’s going to stand the test of time, ” Michaels said of NOAA’s recent adjustments.
But what Michaels and others say is more problematic is the growing divergence between NOAA’s new temperature data versus satellite data and records from the UK Met Office. NOAA’s data shows significantly more warming than Met Office or satellite records.
“It’s a major problem because outside of the north polar region, the upper troposphere is supposed to warm faster than the surface, ” Michaels said.
“Pretty much every projection made by our climate models for sensible weather is simply not at all trustworthy, ” Michaels said.
