A recent NOAA article is just what Doctor Doom ordered. It claims the 18-year “hiatus” in rising planetary temperatures isn’t really happening. (The “pause” followed a 20-year modest temperature increase, which followed a prolonged cooling period.)
Published in Science magazine to ensure extensive news coverage before critics could expose its flaws, the report was indeed featured prominently in the national print, television and electronic media.
It’s part of the twin peaks thesis: Peaking carbon dioxide levels will cause peaking temperatures, which will lead to catastrophic climate and weather. Unfortunately for alarmists, the chaos isn’t happening.
No category 3-5 hurricane has hit the United States for a record 9-1/2 years. Tornadoes, droughts, polar bears, polar ice, sea levels and wildfires are all in line with (or improvements on) historic patterns and trends. The Sahel is green again, thanks to that extra CO2. And the newly invented disasters they want to attribute to fossil fuel-driven climate change – allergies, asthma, ISIS and Boko Haram – don’t even pass the laugh test.
The NOAA report appears to have been another salvo in the White House’s attempt to regain the offensive, ahead of the Heartland Institute’s Tenth International Climate Conference. However, a growing number of prominent analysts have uncovered serious biases, errors and questions in the report.
Climatologists Pat Michaels, Dick Lindzen, and Chip Knappenberger point out that the NOAA team adjusted sea-surface temperature (SST) data from buoys upward by 0.12 degrees Celsius, to make them “homogenous” with lengthier records from engine intake systems in ships. However, engine intake data are “clearly contaminated by heat conduction” from the ships, and the data were never intended for scientific use – whereas the global buoy network was designed for environmental monitoring.
So why not adjust the ship data downward, to “homogenize” them with buoy data, and account for the contamination? Perhaps because, as Georgia Tech climatologist Judith Curry observed, this latest NOAA analysis “will be regarded as politically useful for the Obama administration.” However, it will not be “particularly useful” for improving our understanding of what is happening in Earth’s climate system.
Dr. Curry and the previously mentioned scientists also note that the buoy network has covered an increasingly wide area over the past couple decades, collecting high quality data. So again, why did NOAA resort to shipboard data? The ARGO buoys and satellite network (both omitted in this new analysis) do not show a warming trend – whereas the NOAA methodology injects a clear warming trend.
Britain’s Global Warming Policy Forum succinctly concludes: “This is a highly speculative and slight paper that produces a statistically marginal result by cherry-picking time intervals, resulting in a global temperature graph that is at odds with those produced by the UK Met Office and NASA,” as well as by other exhaustive data monitoring reports over the past four decades.
