Some scientists theorize that global warming a. will eventually result in colder temperatures at the north and south poles b. is the result of increased levels of carbon dioxide in the atmosphere c. is caused by melting glaciers d. will result in a sharp drop in ocean levels

in the long term, the benefits of mitigation will outweigh the costs. climate change can have large consequences, such as more extreme weather events and a rise in sea level. society can adapt to and mitigate climate change to cope with these challenges. both adaptation and mitigation have their costs and benefits.
