What NASA failed to mention, though, was far more important: The agency's own satellite temperature data for last year show that 2014 was only the sixth warmest since NASA» Remote Sensing Systems (RSS) satellites went up less than four decades ago.

Since the satellite record began in 1979, summer sea ice cover has fallen by around 13 % per decade, with rising temperatures playing a large role in the decline.

[8] This was virtually identical to the statement found in the ISPM [ISPM v. 1 2.1 b] and echoed the summary statement: «Globally - averaged measurements of atmospheric temperatures from satellite data since 1979 show an increase of 0.04 °C to 0.20 °C per decade over this period» [ISPM v. 1 ES].

If, however, global temperature where to track the CO2 increase shown on the chart, it would need to increase by 2.54 degrees C. Indeed, the satellite record shows a trend in temperature of 0.14 C per decade, for an increase of 0.43 C since the start of the satellite record.

This time period is too short to signify a change in the warming trend, as climate trends are measured over periods of decades, not years.12, 29,30,31,32 Such decade - long slowdowns or even reversals in trend have occurred before in the global instrumental record (for example, 1900 - 1910 and 1940 - 1950; see Figure 2.2), including three decade - long periods since 1970, each followed by a sharp temperature rise.33 Nonetheless, satellite and ocean observations indicate that the Earth - atmosphere climate system has continued to gain heat energy.34

Florida State University's James Elsner said ground data show every decade has been warmer than the last since the middle of the 20th century and satellite data - based observations «show continued warming over the past several decades.»

«Sure, they'll probably try to confuse us with trick questions: Like why, apart from natural 1998 and 2015 El Nino spikes, satellites haven't recorded any statistically significant global warming for nearly two decades; why sea levels have been rising at a constant rate of 7 inches per century without acceleration; and why no category 3 - 5 hurricanes have struck the U.S. coast since October 2005 — a record lull since 1900.

The current warming trend is of particular significance because most of it is extremely likely (greater than 95 percent probability) to be the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over decades to millennia.1 Earth - orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale.

In particular, over the past three decades (since 1980), robust evidence from satellite observations of the TSI [total solar irradiance] and volcanic aerosols demonstrate a near - zero -LRB--- 0.04 W m — 2) change in the natural forcing compared to the anthropogenic AF increase of ~ 1.0 ± 0.3 W m — 2.»
