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

Climate myths by Carter What the Science Says Usage
"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
6
"It hasn't warmed since 1998" For global records, 2010 is the hottest year on record, tied with 2005. 5
"Climate's changed before" Climate reacts to whatever forces it to change at the time; humans are now the dominant forcing. 4
"There's no correlation between CO2 and temperature" There is long-term correlation between CO2 and global temperature; other effects are short-term. 4
"It's cooling" The last decade 2000-2009 was the hottest on record. 4
"CO2 limits will make little difference" If every nation agrees to limit CO2 emissions, we can achieve significant cuts on a global scale.
4
"There's no empirical evidence" There are multiple lines of direct observations that humans are causing global warming. 3
"It's not bad" Negative impacts of global warming on agriculture, health & environment far outweigh any positives. 3
"Models are unreliable" Models successfully reproduce temperatures since 1900 globally, by land, in the air and the ocean. 3
"CO2 is plant food" The effects of enhanced CO2 on terrestrial plants are variable and complex and dependent on numerous factors
3
"There is no consensus" 97% of climate experts agree humans are causing global warming. 2
"Climategate CRU emails suggest conspiracy" A number of investigations have cleared scientists of any wrongdoing in the media-hyped email incident. 2
"It's a natural cycle" No known natural forcing fits the fingerprints of observed warming except anthropogenic greenhouse gases. 2
"Hockey stick is broken" Recent studies agree that recent global temperatures are unprecedented in the last 1000 years. 2
"It's not happening" There are many lines of evidence indicating global warming is unequivocal.
2
"CO2 limits will harm the economy" The benefits of a price on carbon outweigh the costs several times over.
2
"Al Gore got it wrong" Al Gore book is quite accurate, and far more accurate than contrarian books. 1
"It cooled mid-century" Mid-century cooling involved aerosols and is irrelevant for recent global warming. 1
"It warmed before 1940 when CO2 was low" Early 20th century warming is due to several causes, including rising CO2. 1
"It's Urban Heat Island effect" Urban and rural regions show the same warming trend. 1
"Temp record is unreliable" The warming trend is the same in rural and urban areas, measured by thermometers and satellites. 1
"1934 - hottest year on record" 1934 was one of the hottest years in the US, not globally. 1
"It's the sun" In the last 35 years of global warming, sun and climate have been going in opposite directions
1
"Antarctica is gaining ice" Satellites measure Antarctica losing land ice at an accelerating rate. 1
"Hurricanes aren't linked to global warming" There is increasing evidence that hurricanes are getting stronger due to global warming. 1
"Sea level rise is exaggerated" A variety of different measurements find steadily rising sea levels over the past century. 1
"Greenland is gaining ice" Greenland on the whole is losing ice, as confirmed by satellite measurement. 1
"Arctic icemelt is a natural cycle" Thick arctic sea ice is undergoing a rapid retreat. 1
"Animals and plants can adapt" Global warming will cause mass extinctions of species that cannot adapt on short time scales. 1
"Oceans are cooling" The most recent ocean measurements show consistent warming. 1
"It's not us" Multiple sets of independent observations find a human fingerprint on climate change. 1
"Global warming stopped in 1998, 1995, 2002, 2007, 2010, ????" Global temperature is still rising and 2010 was the hottest recorded.
1
"Earth hasn't warmed as much as expected" This argument ignores the cooling effect of aerosols and the planet's thermal inertia. 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
"It's internal variability" Internal variability can only account for small amounts of warming and cooling over periods of decades, and scientific studies have consistently shown that it cannot account for the global warming over the past century.
1
"CO2 limits won't cool the planet" CO2 limits won't cool the planet, but they can make the difference between continued accelerating global warming to catastrophic levels vs. slowing and eventually stopping the warming at hopefully safe levels 1
"It's El Niño" El Nino has no trend and so is not responsible for the trend of global warming. 1
"Climate sensitivity is low" Net positive feedback is confirmed by many different lines of evidence. 1


Back to Climate Skeptics

whaddaya mean, snaKKKe, "cfannot be followed logically"? Perfectly logical, perfectly clear, and what it all boils down to is Al Gore has been right all along, and the deniers, like you, have had your heads in the sand all along. He was right. The earth is warming. glaciers are melting. Growing zones have all moved one zone north. The arctic ice cap is melting first, as the climate models predicted, which destabilizes the winter weather in the eastern u.s., as the models predicted. Temperature-sensitive coral,home to a large fraction of the world's edible fish, is dieing. The oceans are heating and becoming more acidic. Decreassed snow cover melts earlier, and flows down the rivers to the sea before it can be used to irrigate crops that much of the world's population needs to feed itself. Close to tewnty years ago now, Gore started saying that would happen, AND HE WAS RIGHT. You weren't.

And it's been around twenty years, too, since he told EVERYBODY that green investments and carbon exchange not enly helped the planet but would be good investments. Then he put his own money where his mouth is. He risked his own capital, and now it's paying off. He made no secret of it. If you'd followed his advice instead of ranting, you might be rich too, instead of still sitting down in the basement playing video war games. Tough luck, boyo, you should have listened to Al.

Al Gore is a psychopath, a liar and a thief!...

You left out PIG...

Al Gore is a psychopath, a liar a pig and a thief!...

Forum on climate change postponed due to snow



BOSTON - A legislative forum on climate change has been postponed, ironically, due to the weather.

"I hope these repeated, severe storms serve as a platform for some important conversations around bolstering our natural and built infrastructure against climate change once a new date has been set for this discussion," said State Sen. Marc Pacheco (D-Taunton), who chairs the Senate Committee on Global Warming and Climate Change and organized the summit.

The forum had been scheduled for Tuesday at the Statehouse, but the MBTA is shut down Tuesday as Massachusetts continues to dig out from an unprecedented amount of snowfall.

Pacheco's forum was going to include numerous speakers from environmental organizations and academia as well as Secretary of Energy and Environmental Affairs Matthew Beaton, Senate President Stan Rosenberg (D-Amherst) and other legislators. Raymond Bradley, director of the Climate System Research Center at UMass Amherst, and Richard Palmer, a professor in the Department of Civil and Environmental Engineering at UMass Amherst, were among those who had been slated to attend.

Boston Turns to Snow Farms, Melting Trucks in Desperate Effort to Unclog City Streets



Over the past 30 days, the city of Boston has been pummeled by multiple storms that have dumped more than 70 inches of snow on the city, breaking the previous 30-day record total of 58.8 inches set in 1978.
While clearing the roads and walkways is one challenge, disposing of the large piles of snow scattered around an already congested city is another, especially with a fourth snowstorm forecast to move into New England later this week.
In order to reduce the piles of snow, Boston has opened five ‘snow farms' at vacant parcels of land throughout the city, where work crews continue to unload thousands of truckloads of snow. Yet as one whopper of a storm follows another and frigid temperatures remain, space in Boston grows ever tighter.
The city has received an unprecedented amount of snow, according to Mayor Marty Walsh, and they've had to use industrial snow melters, on loan from Northeastern University and the Massachusetts Port Authority, to melt snow as all five snow farms approached capacity at various points.
Despite the public works department melting more than 6,000 truckloads of snow over the past several days, Walsh told the Boston Globe that the snow melters were struggling to keep up with demand and the city has considered dumping snow in Boston Harbor. However, it would first need to notify the Boston Conservation Commission due to the fact that road salts and other chemicals in the snow could pose an environmental risk.
