Favourite climate myths by William Happer

Below are many of the climate myths used by William Happer plus how often each myth has been used.

Climate myths by Happer What the Science Says Usage
"Hockey stick is broken" Recent studies agree that recent global temperatures are unprecedented in the last 1000 years. 1
"Medieval Warm Period was warmer"

Globally averaged temperature now is higher than global temperature in medieval times.

1
"CO2 lags temperature" CO2 didn't initiate warming from past ice ages but it did amplify the warming. 1
"Models are unreliable"

Models successfully reproduce temperatures since 1900 globally, by land, in the air and the ocean.

1
"CO2 limits will harm the economy"

The benefits of a price on carbon outweigh the costs several times over.

1
"It's not bad" Negative impacts of global warming on agriculture, health & environment far outweigh any positives. 1
"Hurricanes aren't linked to global warming" There is increasing evidence that hurricanes are getting stronger due to global warming. 1
"Greenland was green" Other parts of the earth got colder when Greenland got warmer. 1
"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

1
"CO2 was higher in the past"

When CO2 was higher in the past, the sun was cooler.

1
"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

1
"Extreme weather isn't caused by global warming" Extreme weather events are being made more frequent and worse by global warming. 1
"Climate sensitivity is low" Net positive feedback is confirmed by many different lines of evidence. 1
"CO2 is plant food"

The effects of enhanced CO2 on terrestrial plants are variable and complex and dependent on numerous factors

1
"CO2 is just a trace gas"

Many substances are dangerous even in trace amounts; what really matters is the total amount of CO2 in the atmosphere.

1
"Climategate CRU emails suggest conspiracy" A number of investigations have cleared scientists of any wrongdoing in the media-hyped email incident. 1
"Earth hasn't warmed as much as expected" This argument ignores the cooling effect of aerosols and the planet's thermal inertia. 1
"Ocean acidification isn't serious" Ocean acidification threatens entire marine food chains. 1
"Breathing contributes to CO2 buildup" By breathing out, we are simply returning to the air the same CO2 that was there to begin with. 1
"IPCC ‘disappeared’ the Medieval Warm Period"

The IPCC simply updated their temperature history graphs to show the best data available at the time.

1
"It's not urgent"

A large amount of warming is delayed, and if we don’t act now we could pass tipping points.

1
"Clouds provide negative feedback" Evidence is building that net cloud feedback is likely positive and unlikely to be strongly negative. 1
"Renewable energy investment kills jobs"

Investment in renewable energy creates more jobs than investment in fossil fuel energy.
