Googling your carbon footprint

I decided to have a cup of coffee rather than randomly searching Google for a few minutes. For the good of the planet.

The Sunday Times reported that 2 Google searches have the the same carbon footprint as boiling water for a cup of tea. (I am hoping the same applies to coffee but I’m erring on the side of caution by forsaking half a dozen notional searches.)

These statistics aren’t completely convincing, being generated, as they were, by a guy who’s set up a website to sell a clean conscience to websites.

People want websites they visit to be eco-friendly. CO2Stats helps you attract and retain those visitors.
CO2Stats is the only service that automatically calculates your website’s total energy consumption, helps to make it more energy efficient, and then purchases audited renewable energy from wind and solar farms to neutralize its carbon footprint – all for a flat, affordable monthly fee. (from co2stats)

The estimated carbon footprint of your search varies wildly between

[Wissner-Gross’s] research indicates that viewing a simple web page generates about 0.02g of CO2 per second. This rises tenfold to about 0.2g of CO2 a second when viewing a website with complex images, animations or videos. (from the Sunday Times)

So, “stick to really dull webpages and don’t visit YouTube or sites that use Flash” sounds more immediately effective advice than buying spurious energy credits.

In any case, this turns out to be at the low-end of the carbon footprint estimates:

….. carbonfootprint.com, a British environmental consultancy, puts the CO2 emissions of a Google search at between 1g and 10g, depending on whether you have to start your PC or not. Simply running a PC generates between 40g and 80g per hour, he says. Chris Goodall, author of Ten Technologies to Save the Planet, estimates the carbon emissions of a Google search at 7g to 10g (assuming 15 minutes’ computer use).
Nicholas Carr, author of The Big Switch, Rewiring the World, has calculated that maintaining a character (known as an avatar) in the Second Life virtual reality game, requires 1,752 kilowatt hours of electricity per year. That is almost as much used by the average Brazilian.

Wait, if using a PC at all emits ~60g an hour, ie, 1g a minute, doesn’t that mean you are saving 0.8g a minute by looking at complex websites?

And that bit about “depending on whether you have to switch your PC on” is really confusing. (When I work out how to use my PC without switching it on, I’ll post the information here.)

I am sure that computer use is mostly a waste of energy. I am sure that big powerful servers are even greedier than my PC.

However, I’m not convinced by the idea that you can buy your way out of responsibility for ecological damage. Paying to generate some less-polluting-energy doesn’t mean that the more-polluting-energy you used before suddenly disappears.

Congestion charges, aviation carbon taxes and so on. They all suggest that you won’t cause ecological damage if you can afford to pay for it. It’s like buying and selling medieval indulgences.

This would be great if the Earth was susceptible to bribery. I think these schemes are usually just ways for us to avoid taking any real steps to stop destroying the Earth. In some ways, they are worse than doing nothing, because they give us the illusion that we are taking serious steps to save the environment and that we can do this without any major inconveniences.

And they give the climate-change deniers some pretty obvious strawmen to direct their denying at. For example, here are some of the comments on the Times article:

When does this global warming hysteria end. It seems like all these die-hard environmentalists would like us all living in huts with no electricity, comforts, or heating. Especially considering this freezing winter (against all predictions), I’d like to see them go first.

Like a mouse climbing up the leg of an elephant with rape on its mind. Global warming at/isn’t going to happen

I call for a moratorium on publishing articles like this one. The amount of CO2 generated when my head starts to steam is much higher than a Google search. Multiply that by the millions of sane people who agree with me that GW is a crock and GW might actually come true.

(Replace the misused “sane people” with a more accurate “Americans” and you get the flavour of a lot of these comments. What is it about living the USA that makes some people unable to see beyond their own carports?)

The calculations are ridiculous and blatantly misleading.
But no surprise, it appears that this will be another cold year and the “environmentalists” are running up and down in a total panic that they failed to fully socialize the world while for a few years was a bit warmer.

And why should we care how much energy Google uses…because of the myth of Global Warming that is being forced down our throats.
2007 was the warmest year on record, no wait, we were wrong about that, the warmest year was 1945. Artic sea ice will be gone soon, no wait, we were wrong about that

It looks as if even people who are too monumentally stupid to see that a cold year doesn’t in itself invalidate climate change are still bright enough to see that these figures are a bit bogus.

Why give them ammunition? The idea of a “carbon footprint” as an individual moral issue, susceptible to individual guilt and contrition is just mistaken. It’s obviously good to do whatever we can as individuals, but it’s a social and political issue, which needs serious social and political solutions.
(end opinionated rant.)

Getting climate change and asbestos wrong

You’d think that there had been enough pop science articles about climate change for even the thickest journalists to have grasped that “global warming” is

  • short-hand for complicated climatic processes, more accurately referred to as anthropogenic climate change, which don’t necessarily involve warming in any given place. (For instance, the diversion of the Gulf Stream could make the UK colder.)
  • not specifically identifiable in any given day’s or year’s temperatures in any particular place. Climate is not necessarily the same as weather

I assume that Christopher Booker is not a complete fool. He’s expensively educated, and he studied at Cambridge. So, it’s hard to see why he’s spreading ideas as confused as those in his Telegraph article, where seems imply that climate change is pretty well only “global warming” and the fact that some Russian measurements are wrong makes it all false anyway. (I paraphrase)

The world has never seen such freezing heat
A surreal scientific blunder last week raised a huge question mark about the temperature records that underpin the worldwide alarm over global warming. On Monday, Nasa’s Goddard Institute for Space Studies (GISS), which is run by Al Gore’s chief scientific ally, Dr James Hansen, and is one of four bodies responsible for monitoring global temperatures, announced that last month was the hottest October on record.(from the Telegraph)

Oh dear, Christopher, the point really isn’t whether a given month is “hot”.

How can you explain this to someone who believes that it is somehow discrediting Al Gore’s arguments to mention Al Gore’s name in the context that someone he knows has been misled by being supplied with a handful of duff numbers?

The science is too difficult for me to understand, but I’m pretty confident that it rests on millions of different types of observations, over many years and all parts of the world. And the work has been analysed and peer-reviewed by legions of climate scientists.

So, it’s not actually proven. (And, granted that my own assessment that the climate has changed dramatically over my lifetime, let alone Christopher Booker’s, is anecdotal.) But there seems to be such a serious weight of evidence to support it, it would be pretty dumb to imagine it is contradicted by one month’s error figures.

Pretty well as dumb as this complete misunderstanding of the evidence on asbestosis, for example, on the basis of some spuriously-qualified scientist :

Booker’s articles in The Daily Telegraph on asbestos and also on global warming have been challenged by George Monbiot in an article in The Guardian newspaper
Booker’s scientific claims, which include the false assertion that white asbestos (chrysotile) is “chemically identical to talcum powder” were analysed in detail by Richard Wilson in his book Don’t Get Fooled Again (2008).
Wilson also highlighted Christopher Booker’s repeated endorsement of the alleged scientific expertise of John Bridle, who has claimed to be “the world’s foremost authority on asbestos science”, but who in 2005 was convicted under the UK’s Trade Descriptions Act of making false claims about his qualifications, and who the BBC has accused of basing his reputation on “lies about his credentials, unaccredited tests, and self aggrandisement”.(from the Criticism section of Brooker’s Wikipedia entry)

Deny this

Climate change denialists have yet another serious piece of evidence to  ignore.

The work was produced through a collaboration of the Global Carbon Project, University of East Anglia and British Antarctic Survey. Studies of ice cores found that levels of atmospheric carbon dioxide were rising at a rate that is about a third higher than was predicted only half a dozen years ago.

This increasing rate is not seen as due to an increase in emissions but to an apparently failing planetary capacity to soak up the excess. This is a very depressing finding, suggesting that it might soon be too late to do anything to solve the problem.

The study suggests that

….18% came from a decline in the natural ability of land and oceans to soak up CO2 from the atmosphere.
About half of emissions from human activity are absorbed by natural “sinks” but the efficiency of these sinks has fallen, the study suggests. (From the BBC report of the study)

If you can understand it, the dry pre-publication abstract is available at the Proceedings of the National Academy of Sciences website

Sunny Easter

Thanks to the wonders of Global Warming, the rainy, miserable (obviously offset by Chocolate) Easter weekends of my childhood really are a thing of the past. On Saturday I went out to Stourhead (National Trust property) and the weather was fantastic. Just so you don’t think I am lying, here are some photos:

Stourhead - 7 Apr 07 - Pic 1Stourhead - 7 Apr 07 - Pic 2Stourhead - 7 Apr 07 - Pic 3

As you can see the weather was brilliant. Shame about the polar bears though.

On a more serious note, it amazes me that anyone can deny climate change. Just goes to show how much people can cling to a belief… One of the other reasons to make this post was to try out a geocode plugin I have recently installed. Let me know what you think.

Good diagrams, shame about the message

BBC diagrams about climate change and greenhouse gases are really good. No matter how science-challenged you are the messages are easy to understand.

This accompanies a page that says that the UN Intergovernmental Panel on Climate Change (IPCC) is about to release a report suggesting that the science supports the view that climate change will soon lead to mass extinctions, as well as have some pretty dire effects on human society.

It had me wondering about scepticism. Is there some connection between a willingness to evaluate evidence and be swayed by it and being an atheist. It seems that generally atheists are more likely to look at the proof. Does being a non-believer in gods make people more ready to believe the science?

Those people who refuse to accept the evidence on climate change or evolution or the role of HIV in AIDS, or a number of scientific issues, are often the very people who have the strongest belief in God, to the point of willfully pushing it onto others. Continue reading
