155	"CERN CLOUD experiment proved cosmic rays are causing global warming"		The CERN CLOUD experiment only tested one-third of one out of four requirements necessary to blame global warming on cosmic rays, and two of the other requirements have already failed.
156	"Mauna Loa is a volcano"		The global trend is calculated from hundreds of CO2 measuring stations and confirmed by satellites.
157	"Deniers are part of the 97%"		If anyone claims to be part of the 97 percent, it means they disagree with the contrarian argument that humans are having a minimal impact on global warming.
158	"It's planetary movements"		Blaming global warming on the movements of other planets is little more than 'climastrology' and curve fitting without a physical basis.
159	"Venus doesn't have a runaway greenhouse effect"		Venus very likely underwent a runaway or ‘moist’ greenhouse phase earlier in its history, and today is kept hot by a dense CO₂ atmosphere.
160	"Antarctica is too cold to lose ice"		Glaciers are sliding faster into the ocean because ice shelves are thinning due to warming oceans.
161	"Positive feedback means runaway warming"		Positive feedback won't lead to runaway warming; diminishing returns on feedback cycles limit the amplification.

175	"The 97% consensus on human-caused global warming is a robust result"		The 97% consensus on human-caused global warming is a robust result using two independent methods (volunteer abstract ratings and scientist self-ratings) and consistent with similar previous surveys.
176	"Ben Santer rewrote the 1995 IPCC report"		The IPCC operates by consensus. Ben Santer could not have and did not single-handedly alter the 1995 IPCC report. Accusations to the contrary are simply an attempt to re-write history.

185	"IPCC graph showing accelerating trends is misleading"		All of the statements made in the IPCC report regarding the figure in question are correct and supported.
186	"It's satellite microwave transmissions"		Satellite transmissions are extremely small and irrelevant.

193	"Ljungqvist broke the hockey stick"		Ljungqvist's temperature reconstruction is very similar to other reconstructions by Moberg and Mann.
194	"Loehle and Scafetta find a 60 year cycle causing global warming"		Loehle and Scafetta's paper is nothing more than a curve fitting exercise with no physical basis using an overly simplistic model.
195	"Postma disproved the greenhouse effect"		Postma's model contains many simple errors; in no way does Postma undermine the existence or necessity of the greenhouse effect.
196	"Removing all CO2 would make little difference"		Removing CO2 would cause most water in the air to rain out and cancel most of the greenhouse effect.

212	"No long tail means climate sensitivity is low"		New studies showing climate sensitivity may not be high fail to account for the accelerated warming in the deep ocean, but their estimates are nevertheless within the IPCC expected range.
213	"Northwest passage has been navigated in the past"		In the mid-20th Century, traversing the Northwest Passage was a difficult and dangerous endeavor, whereas today, virtually anyone can accomplish the passage.
214	"Nuclear testing is causing global warming"		CO2 warming is 10,000 times greater than the energy from every nuclear bomb ever exploded.
215	"Planting a trillion trees will solve global warming"		Maximum afforestation and reforestation (close to a trillion new trees) would sequester around 75 billion tons of carbon, which is 7–8 years of annual human emissions at current rates and enough to slow global warming by less than a quarter degree Celsius.
216	"Satellite record is more reliable than thermometers"		Thermometers are more reliable than satellites, so there!
217	"The connection between Hurricane Sandy and global warming"		There are several ways in which human-caused global warming contributed to the damage caused by Hurricane Sandy - by causing higher sea levels (bigger storm surges and flooding), warmer oceans (a stronger hurricane), and more moisture in the air (more flooding).
218	"Tropical thermostat limits sea surface temperature to 30°C"		There is no compelling physical justification to suggest that negative feedbacks restrict sea surface temperature to some maximum.
219	"Veganism is the best way to reduce carbon emissions"		Veganism has the potential to reduce global GHG emissions; however, it is not the only option and may not be the most achievable.
