Posted on 02/19/2014 5:26:40 AM PST by SeekAndFind
Darker Arctic waters, revealed as a result of melting snow caps. are contributing to global warming. This finding was shared as part of the Proceedings of the National Academy of Sciences. The continued melting of polar snow caps is a well-documented phenomenon, with grassroots environmental action group Natural Resources Defense Council (NRDC) confirming NASAs finding that the extent of the polar icecap was the sixth lowest of all time.
Over the course of a decade, the Arctic has lost over 432,000 square miles (1.12 million square kilometers) of ice as compared to the average between 1981 and 2010. The white, reflective surface of the Arctic icecap is believed to be responsible for the reflection of sunlight back into space. The decrease in this reflective surface is believed to cause more heat to be trapped in the atmosphere, perpetuating the cycle of global warming.
In a study published by researchers at the Scripps Institution of Oceanography in California, dark Arctic waters are reportedly contributing to global warming. The extent of this phenomenon has been measured in terms of the reflectivity of Arctic snow. The study indicates that measurements of the reflectivity of sunlight by the Arctic icecaps have declined by about 8 percent in a measurement period between 1979 and 2011 accounting for over 6.4 W/m2 of solar energy that has been absorbed by the oceans during the period.
Despite the cyclic replenishment of snow, climatic changes across three decades have reduced the albedo value of arctic snow from 52 to 48 percent. Professor Veerabhadran Ramanathan, director of the Center for Atmospheric Sciences at the Scripps Institution of Oceanography, said that although scientists have been talking of the Arctic melting and the albedo decreasing for close to 50 years,

Fairly certain that this guys head being shoved up his 5th point of contact is the cause for GW.
Global Warming is a dark science.
I felt obliged to correct the record here.*Nobody* alive today has the *first clue* what the Arctic and Antarctic icecaps looked like 160 years ago....1,600 years ago...16,000 years ago....
Just a simple little $100 million annual budget "grassroots" group.
Sixth lowest? Sixth lowest ice cap coverage of all time, you say? Amazing! We’re all gonna die!!
I wonder where all that added evaporation is ending up?
Just curious, where did you get that graph? Thanks.
As of this writing, there is no Scientifically proven, laboratory tested, peer-reviewed, published article on any known Cause and Effect between the amount of CO2 and change in air temperature.
In the field, for example, the Global ppm of CO2 has increased in the last 17 years, but the Global air temperature has not changed, or has gotten colder depending on the site being measured.
Last year the Arctic Ocean Ice Cap grew in area and thickness with Global CO2 at its highest level, providing yet another addition to the very long list of field test failures to the proponents of the pop-culture, junk science speculation called Global Warming.
CO2 is essential for plants to obtain Carbon, and thus CO2 is an environmentally friendly Green House Gas right along with the most abundant Green House Gas, Water Vapor.
BTW, Water Vapor abundance in the atmosphere is 25,000 ppmillion, and CO2 is 400 ppmillion, +/-, adjusted for volcanic and seasonal variation.
Fear-mongering, Spendaholic Politicians can fool some of the real Scientists some of the time, but they have convincingly proven that they can fool all of the junk scientists all of the time.
Since abundant CO2 is essential for Green Plants to grow by the process of Photosynthesis, we FReepers are duty bound to break down the Spendaholic Politicians Barrycades that un-Scientifically discourage the increased generation of life-giving CO2.
Let us as FReepers storm the Anti-Green Energy, Phony CO2 Barrycades of the Spendaholic Politicians with the following chants:
“Support Green House Gas Increases:
CO2 means more plant food for you;
Carbon is a Plant’s Best Friend;
Make more CO2, not more Taxes;
Bring back our life-giving Coal fired plants:
Support the Green Energy Revolution!
They keep saying what they think is causing “global warming”, yet, they have yet to prove there is global warming.
“Over the course of a decade, the Arctic has lost over 432,000 square miles (1.12 million square kilometers) of ice as compared to the average between 1981 and 2010. “
It is all back now and much more of it. So, to quote there is a loss is a lie.
ONE MILLION SQUARE MILES OF ***NEW*** ICEPACK IN 2013... **** this communist liar.
The fact is 50% more Arctic Sea Ice. That is well known. But all the AGW people still write and speak as if the ice cap were nearly nonexistent. State the fact then act if the actual situation were opposite the obvious and admitted facts.
The Big Government crooks desperately want to keep this hoax alive so they can grow government even bigger.

Thanks for the info. Very useful Site to refute the hysterical warmists indeed.
These guy’s time frames are all over the map and seem to be cherry picked. Years picked are not within the sample.
Like saying that 2012 was warmer than the average of 1910-1920.
