Global warming isn't anything to worry about

In summary, Al Gore is a hypocrite who is trying to make money off of global warming by lying to people. He has not presented any credible evidence that global warming is a natural occurrence. The evidence suggests that it is caused by humans and is a threat to our planet.

Not very good at all, no matter which side of the argument you are on. The fact is that our planets climate is an EXTREMELY complex system which makes it very difficult to model and study.

I see. So you believe that humans altering the climate of the Earth by using energy sources that are convenient is wrong. But even if human produced CO2 is not responsible for global warming humans should alter the Earth's climate for their own convenience? Do you really think that makes any sense?

Topher925 said:
Even if the climate isn't changing from greenhouse gas emissions, then what is the harm of becoming a more environmentally friendly society anyway?



I think this just about sums it all up for me. The point is all we know for sure is that the planet IS warming. There IS a possiblity that we are causing it. We also know that warming is generally a bad thing. However as the system is so complex it is difficult to determine the extent (if at all) the impact we are having.

The choices are:

Wait to see and continue research, but do nothing about the potential problem?
Contine research and progressively move towards a cleaner source of fuel?


As Topher mentioned what is the harm of moving towards a greener society anyway? Not only that but when one of the options carries the risk of permanent damage (which may happen anyway who knows) In this sitation I would tend to choose prudence and err on the side of caution.

It's a pascals wager sort of thing. We have nothing to lose by continuing research but making a progressive attemt to switch to a more sustainable fuel source. In the event that we are the cause of global warming we win. If we arent the cause of global warming, then we haven't lost as the research is good for when it becomes uneconomical to use fossil fuels.

If we continue along the route that TheStatutoryApe implies in the quote. If we are the cause, then by the time we realize it could be too late. If we arent the casue then there is no problem, we just have to start researching alterative fuels sometime in the future.

Environmentally friendly / efficient is a contradiction to what global warming nuts actually want to accomplish. Carbon credits, sequestration, blocking the suns rays are all absolute garbage and will serve only to cripple our economy.

Simply put we have no real alternative to coal since nuclear is still associated with death. Cut off coal and we're back to the stone age.

Now those nuts (on both sides) are what p*** me off about this, the answer is not to go back to living in caves and eating soil, nor just to ignore the situation and carry on burning fossil fuels merrily. The answer comes from investing in research, engineering and new technology.

A carbon offset is acutally a good idea if implememnted correctly. The thing is, anything like this is going to cost people money, which is where the real issue lies. At the moment in the UK we are taxed to oblivion on fuel, I wouldn't mind so much if that tax was actually going to help the situation, I simply suspect its going into the kitty to build more MP's a moat or pay for their porn.[/rant]

This is an analogy to the climate change debate.
What if an asteroid was spotted by astronomers that was big enough to do major damage to the Earth's population and it might be on a collision course with the earth. Let's say it was about twenty years out and also the astronomers were not sure that it would impact the Earth but it would be close. Should we prepare to do something? Should we prepare to meet the climate change problem even if we are not sure?

Well, you could of course think about no-regret measures, anything that reduces our dependence on fossil fuels and that does not shoot oneself in foot.

But the main lesson is that fear rules as it has always done in the history of mankind. In another decade we may wonder why we lost the opportunity to go nuclear, well fear ruled there too and 'weather cooking' has been one of all times.

OK. But I wasn't talking about the stage, but the actors.

I am all for alternative energy and getting rid of coal and oil as energy sources. Coal is probably one of the worst sources of energy we can use from what I have read. To not pollute the environment and achieve 'energy independence' are the best arguments for shifting away from oil and coal. Unfortunately they are not as sexy as 'The sky is falling!'

I just like to see more honest and respectable discussion and argument. Warming of the planet is not bad for the planet it is bad for humans. Saying that allowing the planet to warm for our convenience of energy choices is wrong but altering the planets natural climate to be more hospitable, for our convenience, is a good idea is a rather contradictory and poor argument. Either you are ok with altering the climate for our convenience or you aren't and saying its to save the planet is just plain dishonest.

Yes, I agree that it isn't good at all. For one, climate modeling is extremely complex. It isn't just because the variables are unknown; actually doing the modeling involves a huge amount of computing power. Since it obviously isn't possible to include every single water and air molecule, scientists have to split the atmosphere and ocean into different "chunks" and assume that the chunk is a single, monolithic entity. The smaller the chunks, the more accurate the modeling, but the more intensive the required computing power. Since the parameters--like how much rain forms given a certain temperature, humidity, and aerosol concentration--are not well-known, different sets of parameters have to be tested. To see which set is more reasonable, simulations are run on past climate to see how well it predicts the current climate in a process called "hindcasting". It's a complicated process, and one that isn't too accurate.

I don't know if any of you have heard of Climateprediction.net, but if not, read this:

http://climateprediction.net/

It's a distributed computing project that involves predicting the climate of the 21st century. They've a lot of computing power at their disposal, and have produced some interesting results: http://climateprediction.net/content/scientific-papers

Basically, there's a huge variation in predictions of climate sensitivity, ranging from 2-11 degrees. Much of the higher estimates have been ruled out by hindcasting, but none of the models predict a sensitivity of less than 2 degrees, and certainly none of them say the climate will remain unchanged if we keep on burning fossil fuels. One thing to note is that the scientists running this experiment are well aware of the inherent uncertainties and dedicated a paper to calculating them. Climate modeling isn't ESP research; errors are estimated just as they are in every experiment, and you won't hear a scientist proclaiming global warming as real if the forecasted temperature rise isn't significantly larger than the error.
