Prof. Christy asserts that models are too sensitiv... | From our observations we calculated that value as 1.1 C (almost 2° Fahrenheit), while climate models estimate that value as 2.3 C (about 4.1° F). Again, this indicates the real atmosphere is less sensitive to CO2 than what has been forecast by climate models. | null | Victor Venema Scientist, University of Bonn, Germany: He said without providing evidence for this claim.

Incorrect: IPCC projections have compared well with the observed warming trend. | Globally, weather station data show that the world has warmed by roughly 1 °C so far–as has Australia. The warming trend over the last couple decades has matched climate model projections made during that time period. | It may be that a tipping point will be reached soon and that the world might start to warm rapidly but so far reality has stubbornly refused to conform to the Intergovernmental Panel on Climate Change’s computer modelling.

Misleading: Climate model projections show average long-term trends—by nature they will not "predict" short-term variability such as the "hiatus" period. | Climate models have, in fact, successfully projected the rate of global warming, comparing well with observed global temperature in recent years.

Cherry-Picking: The study relied on several local records of past climate rather than a global compilation, and failed to account for the important di... | Natural changes in climate cannot explain recent global warming, while the human-caused increase in greenhouse gas concentrations matches the observed warming well. The analysis contained in this paper—which includes important mistakes—does not demonstrate that natural cycles are responsible for modern climate change. | Most of the recent warming could be natural [...] we suggest that at most, the contribution of industrialisation to warming over the twentieth century would be in the order of 0.2°C.

And even extreme global warming would not be linked to sulfuric acid precipitation, which occurs on Venus because of volcanic emissions of sulfur gas. | While feedbacks (like the release of greenhouse gas from thawing permafrost) can amplify climate change, the effect has limits. In its current state, Earth is not at risk of “runaway warming” that reaches the extreme temperatures of Venus. | We are close to the tipping point where global warming becomes irreversible. Trump's action could push the Earth over the brink, to become like Venus, with a temperature of two hundred and fifty degrees, and raining sulphuric acid. | null | Andrew Dessler Professor, Texas A&M University: This is definitely hyperbole. What’s correct in it is that Venus has a massive atmospheric greenhouse effect, resulting in a surface temperature of 450 °C or 850 °F (compared to Earth’s of 14 °C or 58 °F).

Inadequate support: No reference is provided for the claim that solar activity is projected to decline beyond other Heartland Institute publications. | It is difficult to project solar activity, but research shows that even a substantial lull in solar activity would be far too weak to counteract human-caused global warming. | Forward projections of solar cyclicity imply the next few decades may be marked by global cooling rather than warming, despite continuing CO2 emissions. | null | Georg Feulner Senior Scientist, Potsdam Institute for Climate Impact Research (PIK): Comment taken from two prior evaluations of similar statements.

Therefore, CO2 levels could not have forced temperatures to rise. | null | Flawed Reasoning: A lag between the initiation of past warming due to other factors and rising CO2 does not mean mean that CO2 cannot have caused temperature to increase further. Misrepresents a complex reality: CO2 has been shown to begin increasing before temperature in some instances of past climate change, but also... | Because of the physics of the transfer of electromagnetic radiation, CO2 acts as a greenhouse gas, meaning that temperatures must increase as the concentration of CO2 increases.

Misleading: The rate of sea level rise is expected to increase as a result of ocean warming and melting glacial ice, so using the current rate to project the fut... | Continuing warming causes an accelerating rise of sea level, impacting coastal regions in a variety of ways—including increasing the damage from storm surge events. | Sea level rise, which was occurring long before humans could be blamed, has not accelerated and still amounts to only 1 inch every ten years. If a major hurricane is approaching with a predicted storm surge of 10-14 feet, are you really going to worry about a sea level rise of 1 inch per decade? | null | Benjamin Horton Professor, Earth Observatory of Singapore: Proxy analysis has clearly shown an acceleration in rate of sea-level rise. Our research* found that the rate of sea-level rise on the US Atlantic coast is greater now than at any time in the past 2,000 years. The research also shows a consistent link between g... |

Weather is naturally variable, but the trend of warming temperatures means that local record highs are set more often, and record lows less often. | The U.S. National Climate Assessment found that U.S. heat waves have already 'become more frequent and intense,' that the U.S. is shattering high temperature records far more frequently than it is shattering low temperature records (just as you’d expect), and that it is seeing correspondingly fewer cold spells. | null | Andrew King Research fellow, University of Melbourne: This is true and is also consistent with findings from other areas of the world.
