Top 10 Global Warming Myths

Skeptic Arguments What the Science Says
"Ice age predicted in the 70s" The vast majority of climate papers in the 1970s predicted warming.
"Hockey stick is broken" Recent studies agree that recent global temperatures are unprecedented in the last 1000 years.
"It cooled mid-century" Mid-century cooling involved aerosols and is irrelevant for recent global warming.
"CO2 lags temperature" CO2 didn't initiate warming from past ice ages but it did amplify the warming.
"Models are unreliable" Models successfully reproduce temperatures since 1900 globally, by land, in the air and the ocean.
"It's the sun"

In the last 35 years of global warming, sun and climate have been going in opposite directions

"Water vapor is the most powerful greenhouse gas"

Rising CO2 increases atmospheric water vapor, which makes global warming much worse.

"Antarctica is gaining ice" Satellites measure Antarctica losing land ice at an accelerating rate.
"Climate's changed before" Climate reacts to whatever forces it to change at the time; humans are now the dominant forcing.
"It's Urban Heat Island effect" Urban and rural regions show the same warming trend.
"We're coming out of the Little Ice Age"

Scientists have determined that the factors which caused the Little Ice Age cooling are not currently causing global warming

"Satellites show no warming in the troposphere" The most recent satellite data show that the earth as a whole is warming.
"Greenland is gaining ice" Greenland on the whole is losing ice, as confirmed by satellite measurement.
"CO2 is not a pollutant"

Through its impacts on the climate, CO2 presents a danger to public health and welfare, and thus qualifies as an air pollutant

"Extreme weather isn't caused by global warming" Extreme weather events are being made more frequent and worse by global warming.
"Temp record is unreliable" The warming trend is the same in rural and urban areas, measured by thermometers and satellites.
"Arctic icemelt is a natural cycle"

Thick Arctic sea ice is undergoing a rapid retreat.
