Homogenization of Temperature Data By the Bureau of Meteorology

Background

I worked for Australia’s Bureau of Meteorology – BOM for 2 years from 1973 to 1975. I was trained in weather observation and general meteorology. I spent 1 year observing Australia’s weather and 1 year observing the weather at Australia’s Antarctic station at Mawson.

As part of it’s Antarctic program, Australia drills ice cores at Law Dome near it’s Casey station. On our return journey in 1975 we repatriated a large number of ice cores for scientific analysis. The globe’s weather and climate records are stored in these ice cores for the past 1 million years approximately.

How To Tell Who’s Lying To You: Climate Science Edition

Scott Adams — known, among other things, as the cartoonist behind the Dilbert series — has an excellent blog on which he posts something thoughtful nearly every day.  His particular interest is in the arts of persuasion.  Recently he has dipped his toe into the subject of “climate science,” with a focus on the apparent inability of partisans on either side of the debate ever to convince a single person to come over from the other side.  Now, suppose you come to this debate with no scientific expertise and no ax to grind for either side.  The debate has very significant public policy implications, and understanding it is important to being an informed voter.  How are you to supposed to evaluate the arguments and come to a view?  Adams comments:

My bottom-line belief about climate science is that non-scientists such as myself have no reliable way to evaluate any of this stuff. Our brains and experience are not up to the task. When I apply my tiny brain to sniffing out the truth about climate science I see rock-solid arguments on both sides of the debate.

Social Cost of Carbon

The monster of all climate modeling efforts is the so-called Social Cost of Carbon (SCC). This involves what are called Integrated Assessment Models or IAMs. These models reflect the fact that, from a policy standpoint, the issue of climate change is simply an enormous environmental impact assessment.

An IAM begins with a CO2 emission model, then adds a climate change model, plus a physical damage-from-climate change model, followed by a global economic damage (from the physical damage) model. This complex combination of models is the ‘integration’ part.

Skeptical Climate Scientists Coming In From the Cold

In the world of climate science, the skeptics are coming in from the cold.

Researchers who see global warming as something less than a planet-ending calamity believe the incoming Trump administration may allow their views to be developed and heard. This didn’t happen under the Obama administration, which denied that a debate even existed. Now, some scientists say, a more inclusive approach – and the billions of federal dollars that might support it – could be in the offing.

“Here’s to hoping the Age of Trump will herald the demise of climate change dogma, and acceptance of a broader range of perspectives in climate science and our policy options,” Georgia Tech scientist Judith Curry wrote this month at her popular Climate Etc. blog.
