Atmosphere, biosphere, lithosphere, hydrosphere, etc – everything about life and the state of this planet
RealClimate has a good post up on strategies used by climate change deniers: Forbes’ rich list of nonsense. The post also includes a long list of misleading ‘facts’ that people are using to argue that nothing needs to be done about climate change.
BoingBoing also linked to the post.
I have previously mentioned my brother Mica’s blog, being written from Brisbane, Australia.
He has some posts up about the ongoing flooding:
True to past form, he has been posting videos alongside his first person accounts.
Talking with my friend Meaghan, the question arose: what is the single most useful thing individuals can do easily to help address climate change? Almost certainly, it is taking some action to influence the politics in their country. For those living in democracies, there is probably nothing more useful they can do than nudging their elected representatives a bit toward understanding climate change, wanting to curb it, and being aware of how to do so.
As BuryCoal argues, the key to dealing with climate change is to stop burning fossil fuels. The more coal, oil, and gas stay underground, the less the climate will change. At the moment, I think that is probably the most important message people can convey to their representatives.
Of course, anyone who you tell that to is likely to come back at you with various objections. Fossil fuels power the world economy, for instance. It may be unrealistic to expect the average citizen to prepare counter-arguments for the major objections they will hear – which range from the realistic to the completely deluded. This major counter-argument, however, seems to have two responses. First, we do have alternatives. The total amount of renewable energy out there is huge, and we have many different ways to capture it. Second, nothing about the universe guarantees our current level of energy use. It may well be that future generations experience leaner times. That is far preferable to a world where they are trying to deal with catastrophic or runaway climate change.
The degree to which members of the general public need to understand climate change and its solutions is debatable. It may well be that the problem can be solved by stealth, without much input from the average individual. My fantasy climate change policy doesn’t call for much in the way of voluntary action. For those individuals who are concerned, I would say that first and foremost they should be expressing their deep concern to their elected representatives, highlighting how climate change is the challenge facing humanity and the most important current force that will determine how future generations live.
Once you have done that, you can go on to take actions that reduce your personal contribution to the problem, like improving the efficiency of your home, going vegetarian, reducing travel, etc. Ultimately, the emergence of society-wide mandatory solutions seems to have a much greater chance of addressing the problem than hoping for bottom-up voluntary actions to do the job.
One North American group focused on encouraging ordinary citizens to lobby their representatives for action on climate change is the Citizens Climate Lobby.
One challenge associated with renewable forms of energy like wind and solar power is that power stations of these types cannot usually produce energy all the time, and may not generate it at the time when it is needed most.
Energy storage is one mechanism for dealing with that, and can rely on various mechanisms like compressed air, pumped hydroelectric storage, and multi-lagoon tidal systems.
It is also encouraging that battery technology is improving. A company called Corvus now makes lithium ion batteries that consist of assemblies of 6.2 kilowatt-hour modules. These can be charged in 30 minutes and discharged in 6. They could be joined together in large arrays of up to 40 megawatt-hours and may eventually be cost-effective in some energy storage and load balancing roles.
Climate change definitely strengthens the case for nuclear power, but it is very hard to determine just how strong that case really is, particularly on economic grounds. Climate change does nothing to lessen the risks associated with accidents or nuclear proliferation, but it does represent some of the most significant risks associated with fossil fuel based forms of electricity generation.
Some of the major barriers to the deployment of new nuclear power plants are cost and long lead-in times. Construction can easily take a decade or more. One means by which both of those issues could potentially be addressed is through the use of small modular nuclear reactors. This is an approach being experimented with by a number of groups, including Russia’s state nuclear energy company (which is building a floating, towable nuclear power station) and firms like TerraPower, which has been enthusiastically endorsed by Bill Gates.
One of the most interesting possible uses for small nuclear reactors is as ‘drop-in’ replacements for the coal-burning parts of old power plants. Potentially, the heat source in a power plant could be switched from the combustion of coal to the fission of uranium, keeping most of the rest of the plant’s infrastructure in place. In particular, such converted plants could make use of existing transmission capacity.
I can’t say whether small nuclear reactors really are a more economical or appealing option overall, but it seems like a technology to watch as the world struggles to find ways to achieve carbon neutrality.
In Now or Never: Why We Need to Act Now to Achieve a Sustainable Future, Tim Flannery raises the question of intergenerational ethics and poverty reduction. He does so with reference to the 90,000 megawatts (MW) of coal-fired electricity generation capacity India is planning to install by 2012 (compared with 478,000 MW installed in China between 2004 and 2010). Flannery writes:
It is futile to tell Indians that they should defer development of power plants until cleaner technologies are available, so that we can spare unborn generations climate change. Why, Indians ask, should they penalize people living today for future, uncertain gains, and do this to help solve a problem that is not of their creation?
I do think there are good answers to those questions. For everyone to refuse to act is to create a suicide pact. Further, what we now know about greenhouse gases obligates us to take action in a way that ignorant previous generations didn’t have applied to them.
Also, if we continue on the world’s present course of unbridled emissions, it will not be abstract future generations that see the first massive consequences. Children born today may live to see the great icesheets of Greenland and Antarctica disintegrating in their lifetimes, alongside enormous other changes that are more challenging to predict.
All that said, Henry Shue makes an excellent point about sustenance versus luxury emissions. Even in an emergency, you sell the jewelry before the blankets. As such, the heavy discretionary emissions of rich places like Canada (things like foreign trips, huge inefficient houses and cars, etc) would be cut before Indian development, in any kind of fair world.
Given the choice between a fairer world that produces disaster, however, and a less fair world that gets the job done, the latter still seems preferable.
As discussed before, one reason why it is so challenging politically to put a price on carbon is because there is large regional disparity in how energy is produced.
This chart – taken from part three of Canada’s latest National Inventory Report to the UNFCCC – shows how each province generates its electricity:
Clearly, it is easier for some provinces to make use of low-carbon options like hydroelectricity than it is for others. Also, much of that hydro capacity was built before policy-makers were seriously concerned about climate change.
That being said, the science is now very clear and the period in which people can justifiably claim ignorance about the climatic consequences of their actions is over. Places that made their energy choices before humanity was aware of all the implications of climate change can make a legitimate case for some adjustment time. That said, the defence of ignorance no longer holds and the clock on that adjustment time is ticking.
Boing Boing has some interesting nerdy stuff in their gift guide. That said, a better choice may be helping the Rainforest Action Network fight mountaintop removal mining.
As discussed before, conventional gifts can be pretty problematic.
Last month, The Economist made a convincing case that a pan-European electricity grid could help Europe move to a future more compatible with a stable climate:
This offshore grid is the germ of a big dream: a Europe-wide system of electricity highways. If it makes sense in the North Sea, it makes even more for wind and solar power from Spain and, one day, solar energy from the Sahara desert. And as well as Norwegian reservoirs, why not store power in existing Alpine valleys? This would reduce the need for more power stations to balance the spikes and troughs of renewables. Moreover if producers could trade energy over the grid in a single market, the benefits could be bigger still. European officials reckon energy savings of some 20-25% would be possible.
Such ideas have nostalgic appeal because the European Union was born from a move to pool energy sources in 1951 in the European Coal and Steel Community. These days the EU can be the community of wind and sun, not to mention gas and nuclear power. The trouble is that such dreams are not cheap. The European Commission this week said that €1 trillion ($1.4 trillion) of investment would be needed in the next decade. Most should come from the industry, but a chunk must also come from already tight public budgets.
They are wrong, however, to claim that rising natural gas consumption is not a major problem. Burning gas may be a better way to get a kilowatt-hour of electricity than burning coal, but both are unacceptable in a world where carbon dioxide concentrations are already dangerously high.
Europe’s improved grid should be connecting energy demand centres to diverse and disparate sources of renewable wind, solar, geothermal, and tidal energy – not perpetuating dependence on fossil fuels.
Here’s a statistic that does a good job of demonstrating just how energy-rich fossil fuels are:
An ordinary gas station gasoline pump transfers about 16 megawatts (MW) of chemical energy while operating. That’s about ten times the power output of the Grouse Mountain wind turbine. For any particular span of time, a nuclear reactor puts out about as much energy as 63 gas pumps.
Also, as mentioned before, a barrel of oil contains energy equivalent to the energy output of an adult human working 12.5 years worth of 40 hour weeks.
