fungi in Alaska begin to adapt to high temperatures, speeding up their metabolism, growing and reproducing at a faster pace. Global warming is increasing with each day that passes and the poles begin to thaw. fungi (mold), also contribute to the production of greenhouse gases. fungi are responsible for destroying the organic matter such as leaves that fall from the trees, and feed nutrients to plants. Fungi breathe as humans; they inhale oxygen and exhale CO2. Because in Alaska most of the time it’s cold, fungi are asleep and do not contribute to global warming, but with high temperatures (10-30 °C), the organisms wake up and generate CO2.
