Greenland Ice Sheet Not Covered In Soot
An anonymous reader writes with word of a a new study of the Greenland ice sheet led by Dartmouth adjunct assistant professor Chris Polashenski, which maintains that the darkening sensed there by satellites is not caused by dust and soot deposited by forest fires and industry, but rather by the slow degradation of the sensors on the satellites themselves.
[Polashenski] and his colleagues analyzed dozens of snow-pit samples from the 2012-2014 snowfalls across northern Greenland and compared them with samples from earlier years. The results showed no significant change in the quantity of black carbon deposited for the past 60 years or the quantity and mineralogical makeup of dust compared to the last 12,000 years, meaning that deposition of these light absorbing impurities is not a primary cause of reflectivity reduction or surface melting in the dry snow zone. Algae growth, which darkens ice, also was ruled out as a factor. Instead, the findings suggest the apparent decline in the dry snow zone's reflectivity is being caused by uncorrected degradation of sensors in NASA's aging MODIS satellites and that the declining trend will likely disappear when new measurements are reprocessed.
Do you expect Retractions? There will be none. Part of the reasons is because those "99% of the scientists were non-existing from the beginning.
What you witnessed is a classical social manipulation, human tendency to conform and to be part of the group. If television tells you that "99% of the scientists" believe that Global warming is real, then you will probably accept additional carbon taxes easier.
The problem is that most of the scientists do agree that humanity is changing the earth. You no longer need to be a scientists to see that. For example, in Europe there are no more large populations of bears, tauruses, wolves and wild horses. These animals became extinct before industrial revolution. Last mammothes on Earth died when humans already knew how to write. Heck, some of the rhinoceros will probably be extinct this decade.
However most of discussions were about a) bankrupting US coal industry and closing coal factories (while China opens new coal electric plant almost every week) and b) imposing additional taxes on the taxpayers of industrialized nations.
No. The ice is thickening. Not running into the water. The edges, in fact, are retreating due to shelf collapses (which may well be the normal course of things... we don't have any kind of a baseline si that we can tell.)

Conveniently Global Warming initiative somehow morphed into the Climate Change, or, more accurately, fight against Climate change. I have to believe that every educated person will agree that the only thing that is constant it is change itself, including climate. Climate is changing slowly, also changes in cycles and has many variables. And yes, human are f***king up the biosphere.

NASA has issued new study saying that Antarctica stated that since 1992, a lot of ice has been added to the continent this is the link to NASA: https://www.nasa.gov/content/g...

Most cynical opponents to those who were pushing Global Warming were citing that it was about the money and carbon tax in the particular.
... are you arguing that now? Do you think scientists are warning about human-made global warming for money and the carbon tax?
I am convinced that in my lifetime I will see another initiative related to the fight against Global Cooling. As such Climate Change is much more convenient because bureaucrats can fight any change irrespective of the direction of the change.
Here is some information about various cooling claims:

Yes, they claim to have found a slight accounting error in the work that attributes the inputs for the observed sea level rise, it was found with new satellites, improved data resolution, and longer time scales. That small portion of the rise must now be accounted for 'elsewhere', it probably won't be until we make similar measurement improvements 'elsewhere'. Remove the politics and this paper is only interesting to beancounter geeks, it does not challenge existing theories or observations, let alone disprove them. Most importantly, it does not change the observed sea level rise.
This paper is actually a continuation of the valuable and ongoing work that the 'climategate' beat up was desperately trying to discredit and disrupt via character assassination. ie - Robust climate data. Climate data sets are collected, cleaned, maintained and published by NASA and other organisations, here's a list of the main data sets used by climate researchers. The IPCC does not perform or fund research or data collection, it summarises existing peer-reviewed publications into various reports aimed at different audiences.
Anyone who genuinely wants to debunk global warming should start here, trust me, climate scientists will respond with collective sigh of releif should anyone succeed.

RealClimate.org maybe wouldn't be the best place to start. There's a lot of very aggressively close minded chaps dominating the forums. I know, who'd have thought that could happen on an internet forum?
Real climate is also co-founded by Michael Mann, whom I really take some issue with. Tell me I'm making a mountain out of a mole hill, but his paleo reconstructions of temperature have really bothered me in the past. Nothing to do with the results, not as much to do even with his methodology now that his later work is addressing and correcting problems. The presentation and usage of the 'hide the decline' trick in graphs is just disgusting. When your paleo reconstruction ends around 1900, just end the graph there. If your paleo reconstruction doesn't show the same temperature rise since 1900 as instrumental, then show that too. What you DO NOT DO, is paste in the instrumental record with a thick enough line to hide the paleo reconstruction since 1900. Even further, don't point to the overlapped instrumental part of the graph as startling and clear evidence of an abrupt trend in the data starting at 1900.
If your wanting to have an open and honest discussion about the evidence, that's a difficult environment. Even scientists with a decent publishing record within the field like Lindzen are put under a microscope for criticism for not conforming to the 'consensus'. Even researchers widely embraced and accepted like Mauritsen have their results heavily disputed and interpreted there. When statisticians like McShane and Wyner take issue with the statistical methods in Mann and others work, Mann takes to his blog for the 'final' word while leaving out any response to their real and legitimate questions and arguments. I'm not anticipating that it's going to be a particularly receptive audience as you seem to believe.
