The number of times heads comes up when you toss a coin, number of students present in class, number of times a person has attended therapy sessions-these are all discrete variables. To help see the difference between continuous and discrete variables, imagine a really tall mountain with a trail leading up to the top.
Climate changes resulting from greenhouse gas increases could also significantly affect water supply and demand. For example, a local increase in temperature of several degrees Celsius could decrease runoff in the Colorado River Basin by tens of percent (25, 48).
Ocean acidification-another effect of global warming. Fossil fuel combustion and industrial processes release over six billion metric tons of carbon into the atmosphere each year.ffects of global warming. It increases the atmosphere temperature, it causes acid rain, Some chemicals emitted by the greenhouse like Chloroflorcarbons breaks the OZON layer which absorps some dengeriouse electromagnatic rediation, so dengriouse electromagnatic rediations like UV (ultrovilat rediations), X-ray etc.
