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.

"99%"of the scientists were non-existant

[Trachman]

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.

Re:Global warming has been changed to Climate Chan

[buchner.johannes]

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.

Your stage of denial is 3, and you are implying a appeal to nature fallacy. Here are the relevant links:

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:
