Medieval Warm Period
Was the earth warmer during the 'Medieval Warm Period' than now? No. Regional temperatures do not represent the global temperature. The Medieval Warm Period (MWP) temperature graphs that people use to claim otherwise, do not represent the global average temperature.

Models Can Be Wrong
It's a common mistake people make... the point is not that models 'can' be wrong. The point is models are 'always' wrong. But that does not mean that they are not relevant and useful for understanding how things work.

Ocean Cooling
Did the ocean actually start cooling and global warming stop? The data showed that the Atlantic had gone cold. But the scientist that was looking at the data knew that the inertia of the system should not allow such a thing to happen. But there it was... in the data. Knowing the models and the forces involved he did some more investigating and found something... he looked at his wife and said "Oh, no,". What's wrong?" his wife asked? He replied, "I think ocean cooling isn't real."

Richard Lindzen
Rebuttal to Richard Lindzen: In general, to support his contentions that global warming is not a serious threat, Lindzen relies on largely unsupported claims pertaining to well reasoned science regarding forcing and feedback's. Some of his contentions have been reasonably contested and in some cases the opposite of his claims have proven true. He tends to say it won't be so bad, but seems to be largely ignoring the economic costs of moving infrastructure and resource scarcity issues.

Ross McKitrick - The McKi 'trick'
Rebuttal to Ross McKitrick, an economics professor sowing the seeds of doubt regarding human caused climate change and global warming? Much like John Coleman, McKitrick uses red herrings and appeals to your 'the living the good life' theme in order to say the climate scientists are wrong and that they can't really prove anything. Like others, he uses facts out of context to support his unsubstantiated opinions.

Station Drop Out
Many in the denialist camp like to talk about the fact that many temperature reading stations were taken out, and that is why the temperature readings showed global warming. But in reality, this is "Pure disinformation". According to Gavin Schmidt (NASA/GISS) "You can do the same analysis with only stations that remained and it makes no difference."

The Copenhagen Distraction
Rebuttal to Bjorn Lomborg on Global Warming: Bjørn Lomborg intentionally or unintentionally obfuscated the political will to mitigate climate change and certainly gained recognition and made money on his assertions. He put together his own conference and called it the Copenhagen Consensus. He wrote a book called 'The Skeptical Environmentalist ' for which the Denmark Ministry of Science found him guilty of 'scientific dishonesty'.

Troposphere Not Warming
This is a common denialist/skeptic meme. The reality is that while there are significant complexities in the tropospheric measurements and models, homogenized analysis indicates that the troposphere is doing what is expected of it in accord with the various models and general expectations.

Volcanoes Emit more CO2 than Mankind
This is a pervasive myth that continues to circulate. The idea that volcanoes put out more CO2 than mankind through human industrial output is patently false. Volcanoes put out around 0.2 Gt (200 million tons of CO2). The facts are clear and measured. As of 2010, humans put out on average of around 27Gt (Twenty Seven 'Gigatons') of CO2 per year. That's 2,700 million tons compared to natural cycles 200 million ton output.
