Document Summary
Halocarbons are extremely effective 12000 x more than co2. H20 0. 5x co2: current [co2] is 395 ppm. 2: causes ice and permafrost areas to melt, decomposition of un-decomposed plant material now occurs in former permafrost soils. Increase temperature has an effect on decomposers: soil was formerly permaforsted, now can decompose, decomposition under aerobic and anaerobic conditions produce different side produces like methane and. It doesn"t mean in the yellow area it will fully die out and dissappear, but it not be as nearly as prevalent and dominant as it is now: modelled altitudinal changes tree line shift. Batrachochytrium (lethal fungus) prefers and thrives in the new climate conditions and negatively affects frog populations. Fungy colonizes skin of frogs and so kills them because they breathe through their skin. Success of fungi is infuenced by climate change climate has become drier and warmer in costa.
