Video of Ian Plimer incorrectly states that human CO2 emissions are not responsible for increased atmospheric CO2 concentrations and global warming

Multiple independent lines of evidence indicate that the present-day increase in atmospheric CO2 is caused by human emissions from fossil fuels and land use change. A significant fraction of annual CO2 emissions remains in the atmosphere each year and has steadily accumulated since the onset of the industrial era, driving global warming. Ocean temperature-CO2 feedbacks are important in millennial-scale glacial-interglacial transitions but do not explain the current atmospheric CO2 increase.

Video interview of Ian Plimer at Sky News falsely claims that a new study announces an incoming ice age, partly based on an incorrect Daily Mail headline

“This video is chock full of false and misleading information, and presented in a way to make the correct scientific information seem like a farce. For example, the direct link between human emissions of carbon dioxide and global warming is very well established. The physics and chemistry of this link has been understood for well over 100 years, and science continues to affirm it.”

Ian Plimer op-ed in The Australian again presents long list of false claims about climate

“This article is a mixture of misdirection, misleading claims, and outright falsehoods. The author attempts to paint a picture of current climate change as simply a continuation of natural changes that have occurred in the past. But this neglects the clear evidence that climate change over the last two centuries has been shown to be largely man-made, that it is much more rapid that anything we have seen in the last two thousand years if not longer, and that it is occurring in the context of a globe with more than 7 billion human inhabitants.”

Water vapor is a greenhouse gas, but it is not a major driver of global warming

Water vapor is fundamentally different from the other greenhouse gasses which directly cause global warming. It leaves the atmosphere in a matter of days and its atmospheric concentration is ultimately governed by temperature. It is critical for the natural greenhouse effect, but it is a negligible contributor to the enhanced greenhouse effect. We already know, beyond any reasonable doubt, that human emissions of the other greenhouse gasses is the primary cause of global warming.

Temperatures on Earth are increasing and the rise is drastically outpacing previous natural changes in the planet’s climate

Temperature data indicate that global temperatures are already higher than at any other period in the past several thousand years. Multiple independent lines of evidence indicate that the Earth is currently warming at a rate that is much faster than past changes in climate. Increasing atmospheric carbon dioxide levels due to human activities are a key driver of this change, as has been consistently shown by a consensus of scientific data.
