Document Summary
2. precipitation, as well as how quickly water evaporates. Forest fires release co 2 which leads to even more warming: normally, tundra hides away carbon in form of soil organic matter due to decomposition rates being extremely low; however, during, documenting positive and negative feedback. Milder temperatures have triggered deadly infestations of beetles in areas where they had not been abundant before, threatening boreal forest ecosystem: copepods are small crustaceans that serve as key primary consumers in marine plankton. Some plants and animals that have restricted geographic ranges and grow on mountaintops are running out of habitat: amphibians are in rapid decline globally due to numerous threats--40% of amphibian species face imminent extinction. Local changes to temperature and precipitation may shrink or eliminate the already narrow ranges of many amphibians: ocean acidification, ocean"s capacity to absorb co 2 is not limitless but is still vast.
