Many “skeptics” have for years already justifiably objected to various aspects of UN-driven climate-alarmism (e. g.: [1] The `Hockey Stick’: A New Low in Climate Science, by John L. Daly; first posted in 2001).

The all-out climate-alarmism propaganda campaign is now dying a slow death. New, well-founded objections are being raised by reputable climate researchers and institutions.  One important fact emerges.  That is that rising atmospheric CO2 levels, of which a minuscule fraction (3%) is due to man-made causes, have little to do with rising global temperature trends.  Still, it is not likely that the mainstream media will soon tell us anything about the fundamental truth that needs to be faced by anyone involved in climate science: the science is not settled, and predictions about climate trends are “unrealistic” because too little is known about what makes Earth’s climate system tick.

Arctic shows no signs of warming

Arctic chills down
“The Arctic shows no signs of warming, according to the latest data from the Danish Meteorological Institute’s Centre for Ocean and Ice. Last month, in fact, virtually every single day saw temperatures below the mean experienced over the last half-century. The Danish data – taken daily – casts doubt on climate models that had predicted a steady warming of the Arctic.”

[5] CO2 field experiment likely to cause “do-over” for climate models

Posted on [6] July 6, 2010 by [7] Anthony Watts

I have two press releases here, one via EurekAlert, and one from Max Planck. Plus at the end a summary of points via WUWT regular [8] Pierre Gosselin. First, a key point. You can see the CO2 respiration of the biosphere in the Mauna Loa CO2 record below:

CO2 Trend for Mauna Loa - note the dip in 2008 when global temperatures plummeted, and the step again from 2009 into 2010 when an El Niño occurred. ([9] More)

[From] a summary of key points via Pierre Gosselin:

….4. The climate is quite temperamental: countless factors are involved and many feedback mechanisms enhance effects such as the anthropogenic greenhouse effect. This makes it difficult to make predictions, especially as many processes in the Earth system are still not completely understood.

….

6. Particularly alarmist scenarios for the feedback between global warming and ecosystem respiration thus prove to be unrealistic.”

….

8. “It is still not possible to predict whether this attenuates the positive feedback between carbon dioxide concentration and temperature,” says Markus Reichstein. “The study shows very clearly that we do not yet have a good understanding of the global material cycles and their importance for long-term developments.”

9. “We were surprised to find that the primary production in the tropics is not so strongly dependent on the amount of rain,” says Markus Reichstein. “Here, too, we therefore need to critically scrutinize the forecasts of some climate models which predict the Amazon will die as the world gets drier.”
