Comment on: Akasofu, S.-I. On the Present Halting of Global Warming. Climate 2013, 1, 4–11

Abstract: A recent article which has set forth new interpretations of Earth’s recent climate history has included some questions of authentic scientific inquiry, particularly related to the impact of ocean oscillations on atmospheric temperatures. In fact, this very issue is currently being investigated by multiple research groups. On the other hand, the claim that a two-century linear temperature increase is a recovery from a recent cool period is not supported by the data. Furthermore, this thermal recovery hypothesis is not connected to any physical phenomenon; rather it is a result of a simplistic and incorrect curve-fitting operation. Other errors in the article are: the claim that the heating of the Earth has halted, misunderstanding of the relationship between carbon dioxide concentration and the resultant radiative forcing, and a failure to account for forcings other than carbon dioxide (such as other greenhouse gases, atmospheric aerosols, land use changes, etc.). Each of these errors brings serious question to the conclusions drawn in the referenced article. The simultaneous occurrence of all of these errors in a single study guarantees that its conclusions cannot be supported and, in fact, are demonstrably incorrect.

Goalposts are not just for sports: Climate deniers use them too!

with 8 comments

The difference is that in sports the goalposts are stationary while climate deniers constantly move them to suit their motives. It appears that even the most ardent climate change deniers are accepting what virtually every publishing climate scientist knows and what every international academy of sciences knows: human activities, especially the burning of fossil fuels such as coal, oil, and natural gas, are causing the planet to warm. And of course, our eyes also tell us. Here in the US and also around the world, we are observing an increase in the frequency and severity of drought, heat waves, fires, and floods. We also see the increasing sea levels which played a significant role in Sandy’s devastation.

So what about those goalposts and climate deniers? Well, the climate deniers are moving their goalposts from their earlier position that humans were not responsible for global warming. Now they accept what experts and our eyes tell us. New goalpost: They will tell you that although the planet is warming, it will not warm very much. (Go ahead and slap your hand against your forehead.)
