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.”

New York Times op-ed claiming scientists underestimated climate change lacks supporting evidence

“Most of the specific facts and statistics in this op-ed are correct, but the overall effect is significantly misleading. The author’s central point is that scientists have been drastically underestimating the scope and the pace of climate change until just the past decade or so, and recent events such as permafrost melting, ice cap loss, and extreme weather events have caught them by surprise. This is simply not true.”

Washington Post article accurately describes latest estimate of accelerating Antarctic ice loss

“The article presents the results of the study accurately, and uses multiple comments from scientists both involved and not-involved in the study to highlight the key findings. Some of the explanations are simplified, and there is a slight attempt at the end to downplay the results by suggesting scientists can’t predict the future. It is correct that the study presented is not making predictions, rather documenting past changes, but the positive trend is what we would expect based on the longer record of change we have for glaciers and ice caps.”

Scientists explain what New York Magazine article on “The Uninhabitable Earth” gets wrong

“While it is clear that ongoing warming of the global climate would eventually have very severe consequences, the concept of the Earth becoming uninhabitable within anywhere near the timescales suggested in the article is pure hyperbole. The author has clearly done very extensive research and addresses a number of climate threats that are indeed major issues, but generally the narrative ramps up the threat to go beyond the level that is supported by science.”

Breitbart article falsely claims that measured global warming has been “fabricated”

“In a cursory attempt at both reporting and climate science, the author glibly highlights a document heavy on accusation and light on reasoned engagement with fact. Implying nefarious motives behind temperature measurement bias correction without providing readers any indication of why this is necessary is misleading and a dereliction of the author’s journalistic responsibility.”
