Trust science ? Part 2...

...Some climate models may need to be "substantially revised" in the light of new research into the airborne particles that seed clouds.One of the most detailed studies to date of the particles, known as aerosols, has found serious shortcomings in existing descriptions of how they arise in nature. The work suggests that one or more unidentified organic gases – produced either naturally or from human activities – has a significant influence on the Earth's cloud cover. The research, reported in the journal Nature, has implications for certain predictions about climate change because aerosol particles and the clouds they seed have a cooling effect on the Earth by reflecting radiation from the sun.Jasper Kirby head of the CLOUD (Cosmics Leaving OUtdoor Droplets) experiment at Cern, the particle physics laboratory near Geneva, studied various gas mixtures of sulphuric acid, water and ammonia – the three gases thought to give rise to aerosol particles at the low altitudes where clouds form...more here...
...and Nigel Calder, writing on WuWT, has this to say... to see it on the broader canvas of the politicized climate science of the early 21st Century, the chief reaction becomes a weary sigh of relief. Although they never said so, the High Priests of the Inconvenient Truth – in such temples as NASA-GISS, Penn State and the University of East Anglia – always knew that Svensmark’s cosmic ray hypothesis was the principal threat to their sketchy and poorly modelled notions of self-amplifying action of greenhouse gases.In telling how the obviously large influences of the Sun in previous centuries and millennia could be explained, and in applying the same mechanism to the 20th warming, Svensmark put the alarmist predictions at risk – and with them the billions of dollars flowing from anxious governments into the global warming enterprise...more here... and from Henrik Svensmark... convincing evidence indicates global warming is caused by cosmic rays and the sun — not humans...The science is now all-but-settled on global warming... but Al Gore, the IPCC and other global warming doomsayers won’t be celebrating. The new findings point to cosmic rays and the sun — not human activities — as the dominant controller of climate on Earth...

Trust science, and scientists ? Sure can...

politicising science by advocating particular responses to climate change (most of which will damage our standards of living for no benefit)
claiming that the IPCC is an impartial review of climate science,
passing off greenpeace and WWF propaganda as credible science,
making catastrophist predictions about future climate,
conflicting themselves by accepting research grants from a government that itself advocates AGW alarmist policies,
playing down uncertainty in their results and claiming the science is settled,
fudging data in order to make it fit with their pre-conceived conclusions,
silencing dissent and skewing the peer-review process (so that it essentially becomes "pal-review")
refusing to share methods and calculations for independent confirmation of their results,
hypocritical do-as-I-say-not-as-I-do attitudes (eg. Al Gore and Flannery, above)
abusing and smearing (dare I say, disrespecting) anyone that dares mention any of the above.Those are the simple reasons why climate science as a discipline has lost respect. The public is not stupid, and it can see when it is being misled. More openness, more debate, more honesty and less divisive language would help reverse the trend. Read the full article here...

A NASA study which analyzes satellite data from the years 2000 through 2011, published in the peer-reviewed science journal Remote Sensing, reports that Earth's atmosphere is allowing far more heat to be released into space than global warming proponents' computer models have predicted.
The data also supports prior studies which suggested that increases in atmospheric carbon dioxide trap is far lesser than what has been claimed by the global warming doomsters. The discrepancy between the model-based forecasts of rapid global warming and meteorological data showing a slower rate of warming has given rise to heated debates for more than two decades. "The satellite observations suggest there is much more energy lost to space during and after warming than the climate models show," Dr. Roy Spencer, study co-author and principal research scientist in the Earth System Science Center at The University of Alabama in Huntsville, said in a press re the oceans." Not only does the atmosphere release more energy than previously thought, it starts releasing it earlier in a warming cycle. "At the peak, satellites show energy being lost while climate models show energy still being gained," Spencer said. When applied to long-term climate change, the research suggests that the climate is less sensitive to warming due to increased carbon dioxide concentrations in the atmosphere than climate modelers have theorized. A major underpinning of global warming theory is that the slight warming caused by enhanced greenhouse gases should change cloud cover in ways that cause additional warming, which would be a positive feedback cycle. Numerous decisive factors, including clouds, solar radiation, heat rising from the oceans and different time lags make it impossible to accurately identify which piece of Earth's changing climate is a feedback from man-made greenhouse gases. "There are simply too many variables to reliably gauge the right number for that," Spencer said. "The main finding from this research is that there is no solution to the problem of measuring atmospheric feedback, due mostly to our inability to distinguish between radiative forcing and radiative feedback in our observations." The research team used surface temperature data gathered by the Hadley Climate Research Unit in Britain. The radiant energy data was collected by the Clouds and Earth's Radiant Energy System (CERES) instruments aboard NASA's Terra satellite. The six climate models were chosen from those used by the U.N.'s Intergovernmental Panel on Climate Change. " Read the full article here...
