This year, the modern environmental movement turns 40. Earth Day in 1970 marked the first mass environmental protest, and whilst some ecological ideas have a much older pedigree, it is only during the past four decades that they have attracted mainstream attention. As the disappointment of the Copenhagen climate talks sinks in, it is easy to be pessimistic about the future of environmentalism. But I would argue that, taking the longer-term perspective, it is still very much in the ascendant.
The “Glaciergate” story is about a claim in the 2007 IPCC report that the Himalayan glaciers would melt by 2035. It turns out that the evidence for this claim was from a speculative comment made by a not-very-prominent glaciologist in New Scientist in 1999. The Times and The Express have gone to town with this story claiming that it undermines the whole of the IPCC.
So, what does it really mean? Read more
It is an increasingly familiar formula – a climate poll is released, the results are interpreted and analysed, and both sides claim victory. The initial analyses are inevitably the ones that scream ‘controversy’, while more considered accounts emerge at a later date. But while the polls may tell us something about public opinion, what do they tell us about climate change? Read more
Following the UEA email hack, it’s become part of the media narrative that opinion is turning against man-made global warming. It’s usually worth checking any such media claim about changes in public opinion that have supposedly occurred following a series of news stories, particularly ‘dramatic revelations’. Read more
In the wake of the “Climategate” affair – the illegal hacking and publication of a huge number of emails from the University of East Anglia’s Climatic Research Unit – I’ve been trying to put together some “points to remember” on the episode, along with some of the key points of evidence. Below is what I’ve managed to come up with. Owing to the story’s media profile, the volume of material out there is now pretty enormous and somewhat unwieldy. Nevertheless, I hope this at least begins to cover most the bases, and will generally be of some use. Read more
Following the announcement of the Copenhagen Accord, John Sauven, executive director of Greenpeace UK, declared Copenhagen “a crime scene”, with the world leaders who brokered the deal “guilty men and women.” Every crime scene demands a post-mortem, and in this entry, I”ll attempt to file a first report. I”ll warn you now: some scenes may disturb. Read more
Keep an eye on the Climate Scoreboard during the next two weeks… Note the dark blue curve in the graphic, this is the probability distribution, it shows the full range of temperature rise the current national emissions proposals would likely give rise to. Currently it’s 2-6 degrees with 3.8 degrees is the most likely outcome (according to their analysis, climate sensitivity etc.).
With my risk managers hat on, it’s hard not to notice that we could go way above 3.8 degrees… it looks like there’s a 5-10% of going over 5 degrees… the sting’s in the tail as they say!
For those of you not following the detail of ‘ClimateGate’ here’s a nice video explaining the meaning of the two most cited “conspiracy-proving” emails. Peter Sinclair also wades in with a short video covering the affair.
While this sort of accurate rebuttal is important, it reminds me of something Randy Olson argues in Don’t be such a scientist – that scientists often obsess too much about substance and accuracy, in every sphere they operate in. Olson even suggests that a scientist’s natural response to being called a bastard would be to present their birth certificate as counter evidence! Read more
A recent report by the Institution of Mechanical Engineers (IMechE) ((http://www.imeche.org/about/keythemes/environment/Climate Change/MAG)) boldly declared that the UK had already failed in its quest to prevent dangerous climate change:
“With only four decades to go, the UK is already losing the climate change mitigation battle. The greenhouse gas emission targets set by the Government require a rate of reduction that has never been achieved by even the most progressive nations in the world. If the UK is realistically going to reach an outcome equivalent to a reduction of 80% by 2050, we need to start mapping out an alternative solution using all engineering methods possible and not only relying on mitigation.”
Can you see where this is going yet? Read more
Given the Telegraph’s position as one of the foremost bastions of spurious climate change coverage, it’s hardly surprising that the paper was quick to seize on a recent piece of misguided misreporting from the BBC – a repackaged blog post by local weather reporter (and now, apparently, the BBC’s “climate correspondent”) Paul Hudson entitled “Whatever happened to global warming?”. According to the Telegraph’s blogs editor, Damian Thompson, Hudson’s article “represents a clear departure from the BBC’s fanatical espousal of climate change orthodoxy”. “BBC executives”, he tells us, “have swung the might of the corporation behind that orthodoxy, often producing what amounts to propaganda.” Read more
