NASA announced this week that April 2016 was 1.1 degrees Celsius warmer than the average of 1951-1980. However, that time frame includes recently “cooked” data wherein earlier decades saw the temperatures adjusted downward, thus making the first decade and a half of the 21st century appear warmer. NASA chose not to use more reliable satellite temperature data, which had documented the April 1998 El Niño weather as actually being warmer, and these temperature anomalies can’t compare with the elevated temperature records of the 1930s, or even 1998.
More troubling, NASA left out the inconvenient truth that these above-average temperatures occur worldwide during strong El Niño years, and that since 1998 (another strong El Niño), there has been a temperature hiatus (or pause) based on the most reliable method for measuring global temps: satellites.
Even climatologist and environmental activist Michael Mann wrote in a recent study that this distortion of the climate record to eliminate the global warming slowdown or hiatus since the turn of the century has been “overstated, lacks sound scientific basis, or/is unsupported by observations.”
Yet it is this distorted record that both NOAA and NASA are using to make these alarmist statements of a so-called string of hottest months. And while NASA’s Goddard director, Gavin Schmidt, acknowledges 2015 got an assist from El Niño, he believes the combination of man-made warming and El Niño warming is sending temperatures spiraling higher.
“This assertion is not supported by the NASA GISS data,” says Dr. David Whitehouse, co-founder of the think-tank Global Warming Policy Forum. “In 2015, no month between January – September set a record for that month.” He also says it is “unwise to use 2015 in any trend analysis” because of that year’s El Niño and to wait for the cooling La Niña effect to assess the temperature record.
In fact, “satellite data shows that 2015 was nowhere near as warm as 1998 or 2010, and that there has been no warming for nearly two decades.” Because NASA and NOAA tampered with the historical data, the “actual temperatures are now diverging at a rate of 1.3 degrees Celsius per century,” writes Tony Heller on his site Real Science (see slideshow).
NASA then declared 2015 the warmest year on record using heavily adjusted temperature readings, and excluding the satellite record and ocean temperatures. That’s important because “70 percent of the Earth is oceans,” and “we can’t measure those temperatures very well,” says MIT’s Dr. Richard Lindzen.
Heller plotted out the actual temps versus the cooked temps to show how much tampering had occurred. If a La Niña episode does occur, it will dramatically lower temps worldwide and have the same, yet opposite, effects on the mid-latitude jet streams. This causes Arctic air usually confined further north to move southwards, invariably bringing more frigid temps, winter storms, and higher heating bills.
