Hansen's 1988 predictions:

Reality falls below predictions by 0.4-0.8

C

CO2 is not a climate driving force

IPCC 2007 predictions:

Every year that we now do not see tremendous increases in temperature will further prove a failure of the model with increasing certainty.

The IPCC and UN cannot claim to be backed by scientists, because science is proving them wrong.

The IPCC predictions keep on failing. Not a single one has predicted actual data. Yet, we increasingly credit them with some near-biblical prophets status."In 1988 Jim Hansen was consulted by the US Senate. He made three predictions about the next 30 years of expected global warming.In fact, temperatures are even lower, than he predicted."The three predictions are shown below (red, green, blue) compared to reality (black and gray).. Thus, using scientific reasoning: if in "[model] then [prediction]", the prediction fails, the model is wrong. "If CO2 is a driving force, then temperature rise of at least 0.8 degrees will occur", if these 0.8 degrees are not reached, then. (Simple, isn't it? Science. Everybody can do it).Figure and citation taken from Ref. [1]See also this (the figure speaks for itself):Note the point at 1998. Reality (blue line) and comparison with IPCC models. At that moment, politicians said "Climate change is accelerating at a much faster pace than was preciously thought by scientists", This, later, proved to be wrong, since in 2012 we can say that real climate temperatures fall well below all models.In 2007 IPCC came with this statement"a warming of about 0.2C per decade is projected" (IPCC Fourth Assessment Report: Climate Change 2007).(Note: a long-term natural trend, not attributed to CO2, is 0.06 degrees per decade)See image below between predictions (colored lines) from 2000 and range of models from 1990 (green and blue shaded areas), and reality (black line). The prediction are well above reality.Image fromcomparison of observed increase in human emission of CO2 with increase in GMTA during the 20century shows no relationship between the two. As a result, the claim by the IPCC of climate catastrophe is not supported by the data.[3] IPCC third assessment report.For more information, contact me at The University of The Algarve,
