Research Summary 2

A raft of recent peer reviewed studies -- many which take advantage of new satellite data -- back up claims that it is emissions from tailpipes and smokestacks (and now factory farmed food animals, which release methane) that are causing global warming. A growing cadre of so-called "global warming skeptics," however, deny these connections and chalk it up to natural cycles.

The article “Global Warming is a Myth,” by Edmund Contoski, claims that global warming is a hoax. He also asserts that carbon dioxide (CO2) has no connection to global warming, the human production of CO2 has little contribution to the greenhouse effect, and that the warming of the earth has benefits.

The evidence Contoski uses says, “Manmade emissions of carbon dioxide were not significant before worldwide industrialization began in the 1940s. They have increased steadily since. Over 80% of the 20th century’s carbon dioxide increase occurred after 1940…the climate also failed to behave according to the greenhouse hypothesis, as carbon dioxide was strongly increasing while global temperatures cooled.” This data showed that with the increase of CO2 emissions, the global temperature trend displayed a decrease, thus there showed no relationship between the gas and global warming.

Furthermore, Contoski provides information from the journal Science that says, “termites alone emit ten times more carbon dioxide than all the factories and automobiles in the world.” In addition, “Natural wetlands emit more greenhouse gases than all human activities combined.” With these facts, Contoski stated that with nature emitting so much more gas than humans, “how much effect could regulating the tiny remainder have upon world climate, even if carbon dioxide determined climate?”

To oppose the position of detrimental effects of global warming, Contoski offers disputes for the claims such as “spread of malaria, more human deaths…a loss of biological diversity…” facts such as the location of the greatest biological diversity—the tropics—an area right next to the equator. Contoski also says that agricultural areas require more heat, and with warming, there can be longer growing seasons, allowing agriculture to spread to some of the colder areas. He also uses the statistic, “Worldwide, far more people die every year from cold than from heat”, to refute the claim that more people could die of global warming.
