2008 Is the Coldest Year of the 21st Century
dtjohnson writes "Data from the United Kingdom Meteorological Office suggests that 2008 will
be an unusually cold year due to the La Nina effect in the western
Pacific ocean. Not to worry, though, as the La Nina effect has
faded recently so its effect on next year's temperatures will be
reduced. However, another natural cycle, the Atlantic
Multidecadal Oscillation, is predicted to hold global temperatures
steady for the next decade before global warming takes our planet into
new warmth. If these predictions are correct, there must be
a lot of planetary heat being stored away somewhere ... unless the heat
output from the sun
is decreasing
rather than increasing
or the heat being absorbed by the earth is decreasing due to changes in
the earth's albedo."
Global warming is a misnomer anyway - it should be called, "global climate instability."
No, the heat output from the sun is not changing to reflect the temperature changes.
Global warming doesn't stop or create the normal cycles. It makes them more active.
The particulate matters in the air reflects light.
Not enough to completly offset the global warming.
Look up global dimming.
The melting of the ice sheets is having a cooling effect on Europe.
The Kruger Dunning explains most post on
..."global climate instability" says to little.
Awe, and here I was going to propose we officially call it "Earth Does Stuff". Too vague?
Hype the headline a little more, will ya?
No one is denying climate change. No one even denies that human activity (or the sun or various natural cycles) influences the change. The argument is over how big a role each factor plays. (Along with accusations of exaggerating selected factors for political or commercial gain.) As with many scientific questions, teasing apart correlation and cause is exceedingly difficult - especially with multi-factor causes.
Mod parent up.. The earth's climate is a control system. As it becomes unstable, you will start seeing more records: cold, hot, rain, drought, record single day temperature differentials, etc.
It's not going to just get warmer over short time periods.. It always amazes me that folks don't realize that.
It would be a lot more interesting if 2008 was the coldest year in the last 100 years instead of the coldest year "this century."
2001, or 2000 for those who short-change the first century, set a record as both the coldest and hottest year of the century. The following year broke one of those records.
Knowledge is how to play a game, intelligence is how to win, wisdom is knowing what game to play.

I've been telling people this for a while. I liken it to a spinning top. When it begins to slow down it starts wobbling and becoming very erratic. The difference is that unlike a top, the climate will eventually begin to restabilize. It just might not stabilize in a way that humans are particularly comfortable with.
This guy's the limit!

Which, conveniently, lets just about any type of weather be attributed to global warming (or is that climate change?)
The liberal (not necessarily Dem) stance is more nuanced than the conservative idea of "More demand so just drill for more oil."
Liberals recognize that fossil fuels are quickly running out and "drilling for more" won't be possible sometime in the future, and that using the fuel as we have been IS environmentally harmful. Conservatives don't care if we run out later, that will be someone else's problem. When you are about to run out of an important and critical resource about the worst thing you can do is ramp up production and burn through your last remaining drops.
Even if we drilled in ANWR and off the coast we would STILL be importing a vast majority of our oil. My objections to those ideas are not based on environmentalism but simple reason. If we could become energy independent by drilling in ANWR I would be the first to say to hell with the wild life, but there just isn't that much oil there when you compare it to how much we use every day. If anything, doing that would simply delay the inevitable and slow our development and adoption of cleaner, sustainable fuel sources.
If you build it, nerds will come. Soylentnews.org
Actually, the conservative stance is a lot more comprehensive than the liberal one of "don't drill no matter what" since conservatives support BOTH the development of alternatives AND attempting to make sure we have the steadiest supply possible until alternatives are viable.
Stupid sexy Flanders.
Queue in 10 million "global warming is a scam", "don't look at me, people didna doit" and "Al Gore is a weenie" comments.
But all of these comments on the legitimacy of global warming/cooling/climate change all ignore one very simple, inescapable fact: Most "carbon-neutral" energy forms can be generated locally. Windmills use the wind in your area. Solar panels use the sunlight from your roof. This is also true for geothermal, ocean-wave, and bio-fueled energy. All can be generated locally, with local resources.
Only oil and nuclear have limited supply.
So if, for example, you were a wealthy, North-American country with a severe foreign-debt problem, you might consider the actual costs of oil in lost lives, civil liberties, currency devaluation, and raw wealth shipped oversees to fund a petroleum addiction. This cost is so huge and multi-faceted it baffles the mind. Average people just cannot even begin to understand wealth drain and cost of this magnitude.
But if we were to generate our energy locally, with renewable resources, not only would we leave a nicer place for our kids, grandkids, and their offspring, we'd also improve our national sovereignty. Rather than fund deadly radicals, we'd fund the nice guy down the street. Rather than ship our cash to entities who threaten us at every turn, we'd fund your next-door neighbors. No matter where you live, no matter who you are, no matter how wealthy you happen to be, this is a good idea.
Ignore the matter of global warming, because there's a much more immediate reason to "go green". And it has nothing to do with carbon footprint, it has to do with the green bits of paper in your back pocket. It will be expensive in the short term. It will pay and pay and pay for generations thereafter.
Which would you rather be remembered as: the generation that ignored the problem until it was too late, or the generation that set your state/country/civilization on a long-term course of prosperity?
I choose the latter, thank you.
I have no problem with your religion until you decide it's reason to deprive others of the truth.
Thank you for this post. I am no scientist, but I am an undergrad in a dual major in Engineering/Science (mathematics), there are certain things that really trouble me about contemporary climate science. For one, there appears to be an over reliance on climate models based on broad sweeping assumptions, and an extreme exaggeration of the capacity of any given model to produce accurate results. Increasingly, the GW science seems to be violating Poppers fundamental philosophy of scientific hypothesis: The only theory worth considering is that which can be disproven. Or rather, science is not about proving as such, it is about disproving. I want to see the falsifiability of climate change theory thoroughly discussed, but it never is, nobody can challenge the models, nobody is allowed to question the methods, nobody is allowed to offer alternative to the mainstream narrative. Its a dangerous place for science to be. More and more I see GW predictions failing the falsifiability test: hot year? Earth is warming, cold year? Earth is unstable due to warming, flood: GW, everything, everything under the sun is being attributed to GW.
The 'consensus' worries me also, moreso in fact. There is rarely consensus in science, especially when dealing with fundamentally complex, non-linear dynamical systems which are proven to be inherently chaotic. Even when a theory is sound and mature, the most important consideration is that you are making predictions by using a model, an inherently and unavoidably flawed model. It is always, always important to cite assumptions and errors when making predictions with any model. But if you question the validity of current climate modelling, you are branded a heretic, a denier, and the worst of all: a skeptic. As if being a skeptic in science is suddenly the wrong thing to do? What happened?
All scientists are skeptics, a scientist without skepticism is no scientist, he is a fool. Worse still believing that computer models are completely trustworthy is like believing your lego starship enterprise will fly you to the moon.
I am not a denier, but I am certainly skeptical. I am certainly open to hypotheses, theories, models and all manner of explanations for given data sets, observations etc. But I am deeply troubled by the way discussion and debate about something as highly chaotic and poorly understood as the climate is shut down so vigorously these days. Worse still, the politicians and economists are on board. I can't help but be just a tad aware that politicians will leap on any populist position and economists are always hungry for new derivatives markets.
