Human activities have dramatically increased atmospheric CO2 levels, causing imbalances in the global carbon cycle
Claim:
Human additions of CO<sub>2</sub> are in the margin of error of current measurements and the gradual increase in CO<sub>2</sub> is mainly from oceans degassing as the planet slowly emerges from the last ice age.
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.”
Ian Plimer incorrectly claims human-caused emissions are short-lived
Claim:
The atmospheric residency time of carbon dioxide is five years and it is quickly sequestered into plants, marine life, oceans and sediments.
The Australian publishes "deeply ill-informed" opinion on climate by Ian Plimer
“This article is an amalgamation of logical fallacies, misleading talking points, and downright factually incorrect statements regarding the physics of the climate system. Every talking point in this article has been debunked many times over and it is astonishing that this was published.”
