According to new computer models used with the imput of current greenhouse gas rates of the world as they are today, the Arctic could be iceless by 2040. They say that this is partially the product of a speeding warmth rate due to the more melted ice resulting in less of an ability to cool the water back down as it absorbs more heat from the sun. This is a much grimmer outlook as noted by the article, since previous reports have given the ice levels times of 2060 or even 2105 before ice fully melted. The outlook gave us much longer if there were reductions in greenhouse gas expulsion: Things with the environment always get me a bit ancy because of the uncertainty in their conduct but the looming possibility of it being a reality, so i'm not sure what to think of this. The lack of real change made is i think what scares me the most, we as one unit of mankind need to enact more progressive measures that substantially decrease our impact on the environment before it's too late.
