Global Warming Skeptic Contradictions
Contradictions | Add New Contradiction
The following table lists skeptic arguments that contradict each other. Please feel free to submit a new pair of contradicting arguments.
| Argument 1 | Argument 2 | Submitter |
| It's geothermal | It's the sun | John Cook |
| It's albedo | It's the sun | John Cook |
| It's the sun | It's CFCs | John Cook |
| It's the sun | It's methane | John Cook |
| It's El Niño | It's the sun | Eric L |
| Comment: McLean et al claimed that El Nino explained so much of the warming there was no room for warming due to CO2. There is nothing CO2 specific about this reasoning, so if the claim were valid it would apply equally well to everything else that has been claimed to be the cause of global warming. | ||
| CO2 is just a trace gas | CO2 effect is saturated | Eric L |
| Comment: There's too little of it to have any effect, and also enough to have all the effect it could ever have? | ||
| Greenhouse effect has been falsified | It's CFCs | James Wight |
| Greenhouse effect has been falsified | It's methane | James Wight |
| Greenhouse effect has been falsified | Water vapor is the most powerful greenhouse gas | James Wight |
| Greenhouse effect has been falsified | CO2 effect is saturated | James Wight |
| Climate's changed before | Climate sensitivity is low | John Cook |
| Comment: Dramatic climate change in the past implies high climate sensitivity which contradicts low climate sensitivity. | ||
| Medieval Warm Period was warmer | Climate sensitivity is low | dana1981 |
| Comment: If the MWP was warmer due to a relatively small external forcing, it means the climate must be quite sensitive. Those who make the low climate sensitivity argument should actually be fans of the original 'hockey stick', which showed little climate variation and thus suggested a low climate sensitivity. | ||
| The science isn't settled | Humans are too insignificant to affect global climate | NewYorkJ |
| Comment: Often contrarians will make claims like "we just don't know and it's arrogant to think otherwise" (perhaps that argument needs to be explored separately) followed or preceded by confident statements presented as fact. | ||
| Technological breakthroughs will fix global warming | It's unstoppable | James Wight |
| Climategate CRU emails suggest conspiracy | Phil Jones says no global warming since 1995 | Rob Painting |
| Comment: Skeptics claim CRU data is fraudulent, yet it's okay to use said data if they think it supports their argument. | ||
| It's cooling | Global warming theory isn't falsifiable | Andy Skuce |
| Models are unreliable | Better to geoengineer | angliss |
| Comment: Projecting the effects of geoengineering requires reliable models. | ||
| Greenland was green | Climate sensitivity is low | James Wight |
| Temp record is unreliable | Earth hasn't warmed as much as expected | James Wight |
| Temp record is unreliable | Hansen's 1988 prediction was wrong | James Wight |
| Temp record is unreliable | Models exagerate projected temperature rise | James Wight |
| Solar Cycle Length proves its the sun | Temp record is unreliable | James Wight |
| Comment: The correlation between temperature and solar cycle length doesn't mean anything if the temperature record is unreliable. | ||
| Temp record is unreliable | It warmed before 1940 when CO2 was low | James Wight |
| CO2 is just a trace gas | CO2 is plant food | John Cook |
| Mars is warming | It hasn't warmed since 1998 | Eric L |
| Comment: The study showing Mars warming was based on two pictures of Mars, the first of them taken in 1977. So it can't be warming here for the same reason it's warming there and also cooling here. | ||
| Mars is warming | Models are unreliable | Eric L |
| Comment: The Mars warming is not directly measured, it was determined by climate simulation. | ||
| We didn't have global warming during the Industrial Revolution | It warmed before 1940 when CO2 was low | Stuart |
| We're coming out of an ice age | We're heading into an ice age | Stuart |
| It's waste heat | Humans are too insignificant to affect global climate | Jacob Bock Axelsen |
| Comment: If waste heat can force the climate, then humans can indeed affect the climate in contradiction with the second claim. | ||
| Climategate CRU emails suggest conspiracy | It's natural variability | rogerfjellstadolsen |
| IPCC overestimate temperature rise | Climate's changed before | rogerfjellstadolsen |
| NASA GISS adjustments introduce warming bias | It's natural variability | rogerfjellstadolsen |
| IPCC is alarmist | We're heading into cooling | rogerfjellstadolsen |
| Medieval Warm Period was warmer | Monckton finds low climate sensitivity | rogerfjellstadolsen |
| IPCC's AR5 admitted it's the sun | IPCC is alarmist | rogerfjellstadolsen |
| Scientists can't even predict weather | Ice age predicted in the 70s | rogerfjellstadolsen |
| Peer review process was corrupted | 900+ peer reviewed papers are skeptical of AGW | rogerfjellstadolsen |
| Ice age predicted in the 70s | We're heading into cooling | rogerfjellstadolsen |
| We're coming out of the Little Ice Age | We're heading into cooling | rogerfjellstadolsen |
| Comment: Latest denier blog theories: Seven New Papers Forecast Global Cooling, Another Mini Ice Age Soon https://climatechangedispatch.com/seven-new-papers-forecast-global-cooling-another-mini-ice-age-soon/amp/ | ||
| They changed the name from 'global warming' to 'climate change' | Other planets are warming | anticorncob6 |
| Comment: (Argument 2 could be many other things.) Global warming is happening naturally, yet they changed the name after noticing no warming. | ||
| Nazis invented global warming | Calling skeptics 'deniers' is equating them to Holocaust deniers | anticorncob6 |
| Comment: You can't compare "skeptics" to those who deny the holocaust, yet you can compare "alarmists" with those who did the holocaust. | ||
| God promised Noah no floods | Climate's changed before | anticorncob6 |
| Comment: "Climate's changed before" relies on scientific data about Earth's past, which contradicts young-earth creationism and Noah's flood. | ||
| AGW advocates wont debate with skeptics | Deniers are part of the 97% | Barry Woods |
| Comment: Comment: by calling sceptics deniers who make contradictory statement AGW advocates try to exclude '"skeptics" from the debate, yet AGW advocates are not immune from making contradictory statements. An example from an new single paper: Lewandowsky, John Cook, Lloyd-Springer Philosphy. http://link.springer.com/article/10.1007/s11229-016-1198-6 The contradictory statement relates to the use of denier, denialist, within a single paper!: 3 statement are: "…views in the “community” of denialists…" "No such corrective processes can be observed in denialist discourse…" "…incoherencies manifest in denialist discourse…" The fourth use in a footnote, which states that: "We use denial as a noun that describes a political or discursive activity but we avoid labels such as “denier” or “denialist” that categorize people." They seem a little confused about who are the people who are incoherent and contradictory, by both simultaneously labelling/categorising a whole group of people as denialist or deniers, but simultaneously stating that they do no such thing. Perhaps John Cook can comment. | ||
| CO2 is good for plants | CO2 is just a trace gas | Barry Woods |
| Comment: Actually I meant to compare = CO2 is plant food - & - CO2 is a trace gas (but can't submit a previously submitted pair) John Cook says they contradict each other, but both these statements are arguably true. (essential for photosynthesis and ~0.04% of the atmosphere) perhaps John can explain why he thinks - CO2 is plant food - contradicts - CO2 is a trace gas | ||
| China pollutes more | Chinese station data is missing | Barry Woods |
| Comment: sounds contradictory, but on close inspection talking about 2 entirely different subjects, not able to link to references of any "sceptics" saying his? this would help. | ||
| Science should keep out of politics | Calling skeptics 'deniers' is equating them to Holocaust deniers | Barry Woods |
| Comment: references to Nuremberg trials (Huhne) for sceptics by politicians can only polarise the debate | ||
| CO2 emissions do not correlate with CO2 concentration | CO2 limits take money away from real threats | johngoldner |
| Comment: 1700 TO 1770 36 ERUPTIONS 1770 TO 1870 94 ERUPTIONS 1870 TO 1958 188 ERUPTIONS 1958 TO 2015 197 ERUPTIONS Volcano data from NOAA | ||
| Models are unreliable | Monckton finds low climate sensitivity | IanR |
| Comment: Low climate sensitivity is a prediction of a model, yet models are unreliable in another context. | ||
| There is no consensus | Climategate CRU emails suggest conspiracy | chuck101 |
| Comment: The argument is that there is a huge conspiracy of the majority of climate scientists to hide inconvenient facts about (lack of) Global Warming, and essentially lie and exaggerate the effects thereof. But if there is no consensus, how can there be a conspiracy? | ||

| Climate 'Skeptics' are like Galileo | Global warming is a hoax | jyushchyshyn |
| Comment: It is the "warmers" who are under pressure to recant. | ||
| Global warming stopped in |
It's internal variability | Bob Loblaw |
| Comment: The "global warming stopped" argument pretends that only CO2 can cause warming, so a pause in warming disproves AGW theory, whereas the "internal variability" argument depends on the idea that many other factors can affect temperatures, so it can't be CO2. | ||
| Our country shouldn't go first | It's too late | jyushchyshyn |
| AGW is religion | God promised Noah no floods | jyushchyshyn |

| Comment: Logarithmic = strong effect for trace gases and little effect for abundant gases | ||
| Models are unreliable | Other planets are warming | jyushchyshyn |
| CO2 is just a trace gas | It's methane | jyushchyshyn |
| Technological breakthroughs will fix global warming | Other planets are warming | jyushchyshyn |

| Technological breakthroughs will fix global warming | It's too hard | jyushchyshyn |
| Any warming will increase downward radiation | CO2 limits will make little difference | jonicol |
| Comment: The second is true. A straight forward and rigorous calculation shows that increased absorption by CO2 is exactly off set by increased absorption of downward radiation so Idown = Iup/4 whatever Nco2 might be, at any frequency. Additional CO2 = no additional warming. Radiation by CO2 at top of Troposphere, enhances cooling. | ||
| The Earth warmed 11 degrees in the last 10,000 years | Most of the last 10,000 years were warmer | James Wight |
| Phil Jones says no global warming since 1995 | It's cooling | James Wight |
| Comment: If the warming trend since 1995 is not statistically significant, the cooling trend since 2002 certainly isn't. | ||
| Humidity is falling | Water vapor is the most powerful greenhouse gas | James Wight |
| Aerosols provide too much uncertainty | Climate scientists are manipulated by funding threats and promises | James Wight |
| Comment: Not contradictory exactly but hypocritical. The reason why we don't have good aerosol measurements is because climate scientists couldn't get funding for a satellite. | ||
| CO2 was higher in the past | CO2 measurements are suspect | perseus |
| Comment: Beck suggests that estimates of CO2 concentrations over the last few hundred years are unreliable however other sceptical sources are happy to accept estimates of CO2 concentrations over hundreds of millions of years ago to ‘prove’ that temperature doesn’t depend on CO2 concentrations Stephen Latham | ||
| It's clouds | Negative feedbacks will stabilise climate | Ari Jokimäki |
| Comment: Usually the negative feedback mentioned is clouds. | ||
| It's clouds | Infrared Iris will reduce global warming | Ari Jokimäki |
| A drop in volcanic activity caused warming | It's the sun | dana1981 |
| A drop in volcanic activity caused warming | Climate sensitivity is low | dana1981 |
| Comment: Volcanic activity hasn't changed significantly, so to explain global warming, climate sensitivity would have to be high. | ||
| It's the sun | Climate sensitivity is low | dana1981 |
| Comment: For the small change in solar output over the past century to explain a non-negligible amount of global warming, climate sensitivity would have to be high. | ||

| It's cosmic rays | Clouds provide too much uncertainty | James Wight |
| Comment: The argument goes that clouds may counteract global warming, which contradicts the notion that cosmic rays are causing global warming via their effect on cloud formation. | ||
| Models are unreliable | CO2 limits will harm the economy | James Wight |
| Comment: The prediction that CO2 limits will harm the economy relies on economic modelling! | ||
| It's not bad | Climate is chaotic and cannot be predicted | James Wight |
| Comment: If we can't predict it, how do we know it's not bad? | ||

| Climate sensitivity is low | It's not bad | Wadard |
| Climate sensitivity is low | CO2 was higher in the late Ordovician | Wadard |
| Comment: ... because climate sensitivity is high. | ||
| Climate sensitivity is low | CO2 was higher in the past | Wadard |
| Comment: You would expect CO2 to have been higher in the past if climate sensitivity is high. | ||
| Greenland ice sheet won't collapse | Models are unreliable | Wadard |
| Comment: You need reliable models to explore the probability of any claim about the future, including that 'the Greenland ice sheet won't collapse'. | ||
| Growing forests can offset our CO2 emissions | Models are unreliable | Wadard |
| Comment: Reliable modeling on available land, water, nutrient, supporting biomass, and other environmental factors is required to calculate how much forest we need to grow to offset our co2 emissions, or even whether we can. | ||
| Better to adapt than mitigate | Models are unreliable | Wadard |
| Comment: One needs reliable civil, construction, engineering, production, financial, risk as well a climate and biomass models in order to best adapt. If we think that models are so unreliable, then it's safer to mitigate. | ||
| 500 scientists refute the consensus | Models are unreliable | Wadard |
| Comment: Comment: 500 scientists need reliable models to refute the consensus. | ||

| Comment: Different time. | ||
| It's not bad | Human CO2 is a tiny % of CO2 emissions | tmurdock |
| It's cosmic rays | Mars is warming | tomhuld |
| Comment: Cosmic rays are supposed to change the climate by affecting cloudiness. This doesn't work on Mars (or Iapetus, or Enceladus). | ||
| Regional climate change is more important than global temperature change | It's freaking cold! | John Cook |
| Comment: When global temperature is high, skeptics point out specific regions with high temperature that are pushing the global average up and hence is a regional phenomenon, not global. But when a specific region is cold, this is cited as proof of global cooling. | ||
| CO2 measurements are suspect | There's no correlation between CO2 and temperature | James Wight |
| Mars is warming | Temp record is unreliable | Eric L |
| Comment: Really, we could tell Mars was warming from two flyby pictures of it but we have no idea what's going on today? | ||
| Better to adapt than mitigate | CO2 limits will harm the economy | Andy Skuce |
| Comment: Bangladeshi farmers are more able to adapt to rising sea levels than rich economies to rising carbon taxes. | ||

| CO2 emissions do not correlate with CO2 concentration | Human CO2 is a tiny % of CO2 emissions | Stuart |
| Comment: Human emissions are small so they can't be the source of the recent rise, but emissions are HIGHER than the recent rise. | ||
| There's no correlation between CO2 and temperature | CO2 lags temperature | Stuart |
| Water vapor is the most powerful greenhouse gas | Clouds provide too much uncertainty | Nick Palmer |
| Comment: I was looking for Argument 2 to be more like clouds cause cooling (Lindzen etc). More water vapour = more clouds | ||
| 900+ peer reviewed papers are skeptical of AGW | Climategate CRU emails suggest conspiracy | Stuart |
| Comment: A conspiracy keeps skeptical arguments out of the peer-reviewed literature, but there are hundreds of skeptical papers out there. | ||
| It's Urban Heat Island effect | Jupiter is warming | Jacob Bock Axelsen |
| Comment: Arg 1 implies that there is no cooling, but there are no cities on Jupiter to cause the Urban Heat Island effect. | ||
| Glaciers are growing | Glaciers have been receding since the 1800's | Jacob Bock Axelsen |
| Comment: glaciers cannot grow and recede at the same time | ||
| Climate is chaotic and cannot be predicted | It's cosmic rays | Jacob Bock Axelsen |
| Comment: Predictability versus a clear prediction... a contradiction | ||
| Models are unreliable | It's the sun | rogel |
| Comment: If you don't admit second order predictability, you can't invoke any external forcing as an explanation for recent warming | ||
| The sun is getting hotter | It's cooling | Jacob Bock Axelsen |
| Comment: If the sun drives the climate, then how can it be cooling? | ||
| Ice age predicted in the 70s | Models are unreliable | Jacob Bock Axelsen |
| Comment: no prediction can be made without a model, but they are unreliable | ||
| We're heading into an ice age | Models are unreliable | Jacob Bock Axelsen |
| Comment: argument 1 is a prediction which can only be made with a model. 2 models are moot. | ||
