Document Summary

Lecture 22 bio220 role of greenhouse gases in climate change. Long-term prediction: ice age continues, exit current interglacial in 10-50 thousand years. 4 pioneers of climate prediction (developed models of climate change: tyndall, arrhenius, bjerknes, richardson. Arrhenius calculated effect of co2 as greenhouse gas: x2 [co2] = increase by 4 c, glacial interglacial due to co2. Increased coal burning = fend off next ice age. Richardson use equations to calculate numerical weather prediction. Eniac"s breakthrough prediction: 24hrs of weather in 24hrs. Weather climate: can"t predict weather far in advance (chaotic nature, climate = statistics of weather, predictable, assess predictive ability via backward prediction (compare to past records, Multiple models: intergovernmental panel on climate change: different groups in various countries on. Albedo reflectivity in energy balance: climate colling associated with uplift of mountain ranges, creation of new snowy regions. Keeling hypothesized annual co2 patterns because of seasons. Ipcc data: increase in temperature and sea level, decrease in snow.

There are lots of reports about the "greenhouse effect" on the news these days. These reports invariably contain dire predictions about the effects of elevated levels of CO2, resulting from air pollution, on climate changes and global warming. Consider all of your observations as you address the following questions. 13. What do plants do with CO2 present in the atmosphere? 14. Would you expect photosynthesis to be more or less efficient under "greenhouse effect" conditions? 15. Predict the overall response of plants to elevated CO2 levels. 16. How might the "greenhouse effect" be impacted by plants' response to it?

Affluent, more developed nations consume disproprtionate amount of Earth's resources and produce a disproportionate amount of wastes, inculding carbon dioxide and other greenhouse gases that are causing global climate change. The consquences of climate change include rising sea level, drought, and extreme weather events. Do you think affuent countries should be responsible for helping poorer, less developed countries bear the financial burden of these consequences?
