Claiming that 'Earth isn't warming, because 2008 was cooler than 1998' is like saying 'Spring isn't happening, because April 15th was cooler than April 1!' To see the long term trend, you have to look at all the data.
Saying "climate change happened naturally in the past, and therefore human's can't cause it" is like saying "forest fires occurred naturally in the past. So there can't be arson."
Variation: Arson and camper carelessness can't cause fires, because forest fires often occurred naturally bef...

"Some say, 'Climate is always changing due to natural cycles. So it can't be us doing it.' That's like saying 'People die from natural causes. So there can't be murder!' Any good crime investigator must develop expertise on natural causes of death, so he can distinguish it from foul play. Sam...
"Science isn't "yes or no." Science is gradually reducing uncertainty. Consider gravity. We know gravity with a fairly high degree of understanding but there are still little areas of gravity theory that scientists are still arguing about exactly how it works. But just because scientists don't h...
Mitigation costs too much? This is like saying 'fixing the dodgy brakes on my car costs too much, so I'm going to ignore the problem.' The consequence will likely be a wrecked car, and you in hospital, broke and suffering. Mitigation is expensive, but not doing it will be far more so.
Renewables too expensive? Navy Secy. Mabus: "Every new technology is more expensive. What if we hadn’t started using computers because they were more expensive than typewriters? What if we hadn't started using cell phones because they were more expensive than land lines? Where would we be?"
"Let me address the argument that CO2 is benign because we exhale it. That's about as good an argument as saying a tsunami isn't dangerous because we drink water."— -- Rep. Jay Inslee at a 2011 committee hearing
"People across the northern hemisphere are facing the fact that a warming planet doesn't get rid of winter ... now is a good time to remind ourselves that weather, like death and taxes, will always be with us." — Robert Henson, University Corporation for Atmospheric Research
Telling the inhabitants of a coral that island that they're safe because sea level won't rise, is like a doctor telling a smoker, "stop worrying, you aren't going to die of lung cancer", while knowing full well that they're doomed to die from a coronary thrombosis. Ocean acidification (OA) and b...
If the Arctic is warming, why was the winter of 2010 so cold? The so-called Warm Arctic-Cold Continent Pattern is "kind of like leaving the refrigerator door ajar — the refrigerator warms up, but all the cold air spills out into the house." Variation: As the Arctic warms, so th...
One man's personal choices tell you nothing about the validity of the science. It's like saying, "Louis Pasteur sometimes neglected to wash before meals, so that proves that bacteria don't cause disease."
Saying 'stopping the Keystone pipeline won't stop global warming,' is like a civil rights skeptic saying in 1960, 'Why Woolworth's lunch counter? Getting served a cup of coffee won't end racism.'
"I wouldn’t characterize wanting to use the brakes on a foggy road as hysteria. Humanity is simply driving too fast for the conditions ahead, and should be more cautious."
Humans have overrun the planet to live in every ecosphere. We have had a dramatic impact on natural resources in every land we have colonised. But our impact pales in comparison with plankton.
"When we look at the last 4 decades, we've seen 0.5°C global warming. Some people say, 'well that's not much!' Then I tell them to think of their bodies: 2°C extra and you'd have a fever. An extra 4°C and you'd be dead!"—Prof. Hans Joachim Schellnhuber.
Does a winter cold snap disprove global warming? That's like saying in April, "Don't tell me the days are getting longer. Look how dark it is tonight!" Wide short-term fluctuations can mask a slow, long-term trend. Global warming won't eliminate winter, any more than long summer...
"...97–98% of the climate researchers most actively publishing in the field support the tenets of ACC [anthropogenic climate change] outlined by the Intergovernmental Panel on Climate Change..." —Anderegg, Prall, Harold, & Schneider (PNAS, 2010).
"This is like saying that if someone else drops more litter than you, then it's OK for you to drop litter."—Dr. Richard Milne
When CC walks his dog, he moves in a straight line, but his dog, TC, tugs on the leash and wanders right and left. TC is Temperature Change (short term variance) and his owner, CC, is Climate Change (long term trend). Of course, they both arrive at the same destination.
Fossil fuel industry is the only industry on earth throwing its waste out for free. If you run a restaurant, you have to pay someone to cart away your garbage. - inspired by Bill McKibben

‘People ask me: Is there a pause in global warming? My response: paws are for kittens & puppies. Global warming is still increasing.’ - Joshua Willis NASA Climate Scientist
Farmers know that plants grow best when all their needs are in balance, not just more and more CO2. Crops also need water, nutrients, correct temperature, pollination, weed & pest control, etc. Global warming means more droughts and floods. No amount of CO2 will grow corn in a ...
Human's aren't the first species to alter the atmosphere; that distinction belongs to cyanobacteria, (blue-green algae) which, some two billion years ago, invented photosynthesis. But we are the first species to be in a position to understand what we are doing.
Saying that CO2 is "only a trace gas" is like saying that arsenic is "only" a trace water contaminant.
Saying a cold winter disproves long-term global warming is like the guy who wins two hands of poker and thinks he's figured out how to 'beat the house.' Time to double down on his bets, right?
"The excess CO2 that is pumped into the air today will affect our planet for thousands of years into the future. I am not an alarmist, but I am alarmed. You should be too."—Dr. Stephen Mulkey.
"Man has been appointed as a steward for the management of God's property, and ultimately he will give account of his stewardship." (Luke 16:2)
Just as bad as wearing outdated disco clothes is believing this outdated idea: 'scientists still disagree if humans are causing climate change.'
"'Coal = Jobs.' Yes, for lung doctors."—Thomas Friedman, New York Times Columnist
"Past climate change is not a source of comfort. It's a cause for concern."— John Cook
"This generation has altered the composition of the atmosphere on a global scale through...a steady increase in carbon dioxide from the burning of fossil fuels." - President Lyndon Johnson, special message to Congress, February 8, 1965.
Sure, the climate always changes—just like asteroids have always hit the Earth. But does that mean that a big asteroid hitting the Earth today would not have a serious impact on human civilisation, just like the one that wiped out the dinosaurs, 65m years ago?
“Is heart surgery preferable to a good diet? Of course not. Let’s go for the good diet.”—Bill Gates, on geoengineering.
Just as silly: 'hyping real or imagined errors that make no difference to any significant scientific conclusion.' - Dr. Michael E. Mann
Do you believe information provided from the Watergate Burglars? No, neither should you believe computer hackers who steal private e-mails from scientists.
"A wait and see policy may mean waiting until it is too late." — 1979 National Academy of Sciences report, Carbon Dioxide and Climate: A Scientific Assessment.
Galileo championed the idea that Earth revolves around the sun, but some of his evidence was later proven wrong. Today, peer review and consensus are how science errors get corrected. "People who say science is not about consensus, do not understand science."
In 1931, a book was published, "100 Authors Against Einstein." Albert Einstein's response: "If I were wrong, then one would be enough."
"It's getting warmer. Storms are getting stronger...and it's getting harder to say this is an accident of nature" — Dr. Stephen Schneider.
"Don't look now, but that hoax just ate New Jersey."— Melinda Henneberger, Washington Post.
"The odds that natural variability created these [recent weather] extremes are minuscule... To count on those odds would be like quitting your job and playing the lottery every morning to pay the bills."—Dr. James Hansen, NASA
"(Climate Change) is ultimately an argument of humans vs. physics. It is not Republicans vs. Democrats, liberals vs conservatives, or environmentalists vs. industry. This issue is about whether the planet can live compatibly with our complex human brains." - Bill McKibben, climate activist and fou...

'When you focus on just atmospheric heat to measure global warming, it's like tracking the tip of your dog’s tail to determine its location, instead of the body of the dog.' — Greg Laden, biological anthropologist and science communicator.
"the climate changed before so we aren't changing it" is like saying "beavers felled trees before mankind, so lumberjacks cannot exist." — Sebastian Sassi
“Taking 1998 as the starting year is a joke. Why not 1997 or 1999? Anyone doing this gets an ‘F’ grade in introductory statistics.” — Pieter Tans, a climate scientist who worked on the 2013 IPCC report.
'Yes, the climate changed before. That's called an observation, but a scientist’s role is to explain why it changed before and now. — Peter Hadfield, retired British journalist and creator of popular science YouTube channel Potholer54,
“Every great scientific truth goes thru three phases: 1st people deny it, 2nd they say it conflicts with the Bible, 3rd they say they knew it all along.” — Neil deGrasse Tyson, American astrophysicist and science communicator.
'Certain gases trap heat in our atmosphere...Anyone who tells you that's uncertain is either very confused or they're lying.' — Naomi Oreskes, Professor of Science History at the University of Califormia (San Diego)
