Arctic temperature amplification takes a hit in GRL

From Wikipedia: Polar amplification is the greater temperature increases in the Arctic compared to the earth as a whole as a result of the effect of feedbacks and other processes. It is not observed in the Antarctic, largely because the … Continue reading

Mercury in California fog linked to ocean upwelling

From the AGU fall meeting in SFO and the University of California – Santa Cruz  comes this rather odd statement that I thought was interesting. It seems like an ecological horror story until you realize it is all natural processes … Continue reading

RC’s Dr. Eric Steig boreholes himself on Antarctica

This is something that needs wider circulation, hence its appearance here. I’ve been mulling over how to best present this, and decided there’s nothing I could do in the way of excerpts that still told the story effectively, so I … Continue reading

Has Trenberth’s missing heat been found? Southern Oceans are losing heat

A paper published August 20th in Geophysical Research Letters finds from newly deployed observation systems that the Southern Oceans show an annual net heat loss of -10 Wm-2. Key Points Southern Ocean air-sea fluxes are under-observed, leading to large uncertainty … Continue reading

Earth’s entire thermal infrared spectrum observed

From AGU highlights, interesting, but readers should note that this is one point on Earth in Chile, not a summation of the  atmospheric absorption, emission, and transmission of infrared radiation for the entire globe. For first time, entire thermal infrared … Continue reading

Study shows the Arctic was much colder while Earth was warmer during Eemian warm period

Warm Climate – Cold Arctic? The Eemian is a poor analogue for current climate change 12.06.2012/Kiel. The Eemian interglacial period that began some 125,000 years ago is often used as a model for contemporary climate change. In the international journal … Continue reading

Pollution enhanced thunderstorms warm the planet?

From the DOE/Pacific Northwest National Laboratory, a new paper in GRL saying something that doesn’t make much sense to me. As shown in the diagram above, thunderstorms transport heat from the lower troposphere upwards. The heat source at the base … Continue reading

Trenberth’s missing heat still missing: new paper shows a near flat ocean temperature trend – 0.09°C over the past 55 years

A new paper published today in Geophysical Research Letters describes how the oceans have warmed only 0.09°C over the last 55 years, from 1955-2010. Don’t let the red line fool you, read on. Key Points A strong positive linear trend … Continue reading

From Schmidt 2005 to Miller 2012: the “not needed” excuse for omitted variable fraud

Guest post by Alec Rawls Miller et al. 2012 recently provided some pretty strong evidence for a solar driver of climate. “This is the first time anyone has clearly identified the specific onset of the cold times marking the start … Continue reading
