"Land-Ice" called Permafrost at risk of destruction
There was a post on the blog which discussed the connection between carbon and temperature, and the effect that these two things have on our earth. This is exactly what I wrote my research paper on so I thought I would elaborate more in the "land ice" that Lyndsay mentioned. This "land-ice" is also known as the arctic permafrost, and extensive research done by scientists in the past few years have shown that temperature and carbon have both been the large cause of the disintegration of the permafrost. Carbon is stored in this land ice layer and as it is emitted into Earth's atmosphere, the temperature around the Earth, not just in arctic regions is increasing. It has brought on great concern regarding the condition of the permafrost, and scientists have concluded that the image of the Earth's arctic which holds the staple of the white ice permafrost is drastically changing. With the disappearance of the permafrost, the temperature across the rest of the Earth is increasing. Scientists have said that the disappearance of the permafrost is increasing the amount of Carbon in the atmosphere and also raising the temperature of the Earth. Unfortunately, it seems that as this"land ice" continues to disappear, the planet is only more susceptible to the dreadful effects of global warming. To quote a research scientist Matthew Sturm, who did extensive field work to investigate the condition of the permafrost; "As long as this highly reflective cover is intact and extensive, sunlight coming directly into the Arctic is mostly reflected back into space, keeping the Arctic cool and a good repository for the heat brought in from lower latitudes. But if the cover begins to melt and shrink, it will reflect less sunlight and the Arctic will become a poorer repository, eventually warming the climate of the entire planet."
