We discussed the arctic tundra in class as a biome. These scientists are looking into the permafrost and what possibly could happen if large amounts of it 'defrost' in the coming years. It seems that they are worried about the amount of methane and carbon dioxide that could be produced.
Comment on the the ecology of the biome and how heating up the permafrost could affect the entire ecosystem. AP Biology students might also want to focus on the positive feedback look that is mentioned in the article. Lastly, determine whether this is valid science and worthy of the money invested by the Department of Energy
