Document Summary

Basic principal energy in earth (cid:224) in=out, done by matching the inputs and outputs: inputs=outputs, earth re emits heat, and greenhouse gases captures and doesn"t let it get reemitted, so we have a deficit, in this surface in order to achieve energy balance earth has to heat up so it can reemit, so the temp of the earth is raised by 33 degree"s, greenhouse gases act as a blanket that increases surface temperature, earths temperature with or without greenhouse gases the different in temp without is 19, with is 14. Components of the climate system the lithosphere. Oscillating system weathering start here! start here! bicarbonate ion reacts with minerals reacts with minerals. Summary of interactions between components of climate system. Oxygen isotope ratios 18o / 16o can help estimate past volumes of ice-sheets. Oxygen isotope ratios o / o can help estimate past volumes of ice sheets: warm period normal ratio o18/o16, glacial period (cid:224) oceans are enriched in o18.
