FEAR of global warming is a preoccupation of western societies at the beginning of this 21st century. This fear is usually explained in terms of changes in the surface temperature of the earth as averaged from varying numbers of thermometers from around but the world. But given the many disputes concerning how this data is collected, compiled, adjusted and averaged (see notes and links below), it would perhaps be better if there was some agreement to focus on the temperature as measured from one or just a few sites.
Tim Curtin has suggested that as carbon dioxide concentrations are reported for Mauna Loa, Hawaii, why not also focus primarily on this site when discussing global warming? [Read more…] about Let’s Stop Averaging Global Temperatures (Part 1)
Climate & Climate Change
High Fashion and the Climate Crisis
VOGUE is an exclusive magazine about what is really fashionable. This month Vogue Australia has a feature on the ‘Climate Crisis’.
Australian Green’s Senator Christine Milne explains in the article that unless we change our ways there may be no polar bears in the wild and Australia will lose its natural icons. The Great Barrier Reef, Kakadu and the snow caps on the Snowy Mountains will apparently be gone by 2030. Also, our beaches will have eroded and many Australian cities will be in managed retreat.
The solution, according to the Senator, is for women to “roll up their sleeves just as our great-grandmothers did in the Women’s Land Army during World War 11” and reduce our personal impact on the climate by one tonne of carbon dioxide in a year.
The fashionable way to achieve this is through simple choices including turning the airconditioner down a notch, catching the train once a week and reducing, reusing and recycling what we buy.
It can’t be easy getting a story in Vogue. It is testimony to the widespread appeal of this doom and gloom issue that it is featured in this month’s issue. Of course almost all of what is written is untrue, but then fashion has never been about the truth.

Chamber of Commerce Wants Trial on AGW
The business lobby, hoping to fend off potentially sweeping emission limits, wants the US EPA to hold a ‘Scopes’-like hearing on the evidence that climate change is man-made. Read more here.
Understanding Ice Sheets and Collapse
“FOR a glacier to maintain its present size it must have precipitation as snowfall at its source. This leads to a slightly complex relationship with temperature. If the regional climate becomes too dry, there will be no precipitation, so the glacier will diminish. This could happen if the region became cold enough to reduce evaporation from the ocean. If temperatures rise, evaporation is enhanced and so therefore is snowfall. Paradoxically a regional rise of temperature may lead to increased growth of glaciers and ice sheets. Today, for example, the ice sheets of both Antarctica and Greenland are growing by accumulation of snow…
“In the Greenland ice sheet several cores have more than 3 km of undisturbed ice which go back in time for over 105,000 years, much less than the Antarctic equivalent. The Vostok cores in Antarctica provide data for the past 414,000 years before the ice starts to be deformed. Dome F core reached 3035 m and Dome C core 3309 m, and both date back to 720,000 years. The Epica core in Antarctica goes back to 760,000 years, as does the Guliya core in Tibet. But what is more important than the age is that vast thicknesses of ice are preserved, and they retain complete records of deposition, in spite of the fact that temperatures at times during that period have been warmer than now. They do not fit the model of surface melting, either now or then. After three quarters of a million years of documented continuous accumulation, how can we believe that right now the world’s ice sheets are collapsing!” [Read more…] about Understanding Ice Sheets and Collapse
Stopping Volcanoes?
If our climate catastrophists want to twiddle the dials and stop climate change, they need to play God and change radiation in the galaxy, the Sun, the Earth’s orbit, tidal cycles and plate tectonics. Once they have mastered volcanoes, then we can let them loose on climate change. Read more here.
