Climate & Climate Change

BARACK Obama in his inaugural speech promised to “roll back the spectre of a warming planet.” In this context, it is worth contemplating a passage from his book ‘Dreams from My Father’. It reveals a lot about the way we view the world’s problems.

Obama is in Kenya and wants to go on a safari. His Kenyan sister Auma chides him for behaving like a neo-colonialist. “Why should all that land be set aside for tourists when it could be used for farming? These wazungu care more about one dead elephant than they do for a hundred black children.” Although he ends up going on safari, Obama has no answer to her question. That anecdote has parallels with the current preoccupation with global warming. Many people — including America’s new President — believe that global warming is the pre-eminent issue of our time, and that cutting CO2 emissions is one of the most virtuous things we can do.

To stretch the metaphor a little, this seems like building ever-larger safari parks instead of creating more farms to feed the hungry.

Make no mistake: global warming is real, and it is caused by manmade CO2 emissions. The problem is that even global, draconian, and hugely costly CO2 reductions will have virtually no impact on the temperature by mid-century. Instead of ineffective and costly cuts, we should focus much more of our good climate intentions on dramatic increases in R&D for zero-carbon energy, which would fix the climate towards mid-century at low cost. But, more importantly for most of the planet’s citizens, global warming simply exacerbates existing problems.

THE recent report in the journal Nature of an unexpected Antarctic warming trend has created a certain amount of skepticism – even among supporters of AGW. [1]

But in an AP news story, two of its authors (one is ‘hockey-stick’ inventor Michael Mann from the Real Climate blog) argue that this refutes the skeptics and is “consistent with” greenhouse warming.  Of course, as Roger Pielke, Jr, points out, not long ago we learned from Real Climate that a cooling Antarctica was ‘consistent with’ greenhouse warming and thus the skeptics were wrong: “So a warming Antarctica and a cooling Antarctica are both ‘consistent with’ model projections of global warming. Our foray into the tortured logic of ‘consistent with’ in climate science raises the perennial question, what observations of the climate system would be inconsistent with the model predictions?”

The results are based on very few isolated data from weather stations, plus data from research satellites.  And here is the rub: these are not data from microwave sounding units (MSU), such as are regularly published by Christy and Spencer, but data from infrared sensors that are supposed to measure the temperature of the surface (rather than of the overlaying atmosphere, as weather stations do).
