Interesting climate facts

" Ø The RSS satellite dataset shows no global warming at all for 223 months from January 1997 to July 2015 – more than half the 439-month satellite record.

Ø There has been no warming even though one-third of all anthropogenic forcings (CO2) since 1750 have occurred since January 1997, during the pause in global warming.

Ø The entire RSS dataset from January 1979 to date shows global warming at an unalarming rate equivalent to just +1.2 Cº per century.

Ø Since 1950, when a human influence on global temperature first became theoretically possible, the global warming trend has been equivalent to below +1.2 Cº per century.

Ø The global warming trend since 1900 is equivalent to +0.75 Cº per century. This is well within natural variability and may not have much to do with us.

Ø The fastest warming rate lasting 15 years or more since 1950 occurred over the 33 years from 1974 to 2006. It was equivalent to +2.0 Cº per century.

Ø Compare the warming on the Central England temperature dataset in the 40 years 1694-1733, well before the Industrial Revolution, equivalent to 
+4.33 C°/century.

Ø In 1990, the IPCC’s mid-range prediction of near-term warming was equivalent to +2.8 Cº per century, higher by two-thirds than its current prediction of +1.7 Cº/century.

Ø The warming trend since 1990, when the IPCC wrote its first report, is equivalent to +1 Cº per century. The IPCC had predicted more than two and a half times as much.

Ø To meet the IPCC’s central prediction of +1 C° warming from 1990-2025, in the next decade a warming of 0.75 C°, equivalent to +7.5 C°/century, would have to occur.

Ø Though the IPCC has cut its near-term warming prediction, it has not cut its high-end business as usual centennial warming prediction of +4.8 Cº warming to 2100.

Ø The IPCC’s predicted +4.8 Cº warming by 2100 is well over twice the greatest rate of warming lasting more than 15 years that has been measured since 1950.

Ø The IPCC’s +4.8 Cº-by-2100 prediction is four times the observed real-world warming trend since we might in theory have begun influencing it in 1950.

Ø The oceans, according to the 3600+ ARGO buoys, are warming at a rate of just 0.02 Cº per decade, equivalent to +0.23 Cº per century, or +1 C° in 430 years.

Ø Recent extreme-weather events cannot be blamed on global warming, because there has not been any global warming to speak of. It is as simple as that."
