Document Summary

Env100y5- lecture 49- the climate system and climate change: (continuation) Scientists test climate models by entering data from the past to see if it accurately replicates the present. Ipcc summarizes evidence of climate change and predicts future impacts: intergovernmental panel on climate change (ipcc, trend = pattern that persists within a data set, even after a short-term fluctuations and anormalies have been accounted for. Not the most potent greenhouse gas, but it is abundant: major contributor to the anthropogenic or enhanced greenhouse effect. Human activity has released carbon from sequestration in long-term reservoirs. Human activities accelerate the fluxes of material from one reservoir to another in biogeochemical cycles: ex. Warming of average temperature, resulting in changes in: evapotranspiration rates, surface runoff, soil moisture, temperature means and extremes. Changes in atmospheric circulation and weather patterns, resulting in changes in: plants/animal habitats, frequency and intensity of storms, floods, droughts, growing seasons for crops.
