Document Summary
Co2 in ocean decreases ph, more acidity, sea butterflies go extinct cuz shell dissolves: mosquito population will increase, spreading diseases. 15-37% species extinct by 2050: 6th mass extinctions. Water vapor 4: green house gasses: co, co2, methane, ozone (can damage tissue), h2, Fluorochlorocarbons, water vapor: chapman cycle: o2 + uv-c = 2o, 2o + 2o2 = 2o3, cl + o3 = clo + o2, o3 + uv = O2 + o, clo + o = cl + o2. We use o2 and create o3 with the chlorine that we produce, creating more o2, creating more ozone, and so forth. O3 is safe in stratosphere because it protects from uv-b and uv-c. Cfc"s, hcfc"s, and halons also damage: cfc and hcfc are coolants, halons move into stratosphere, stable there. But when there, they can be hid by. Uv-b or c and do something with radicals up there: have long lifes, read up on these shits on lecture slides.
