Question

How can we model future changes in the global climate with the scientific models available?

Plllease Give Me a good answer! :)

Thanks!!!

Answer 1

1)  First we bum a quarter from a conservative

2)  We assign a value to each side of the quarter

3)  We flip the quarter

4)  We record the outcome of the flip

5)  When recorded results do not match expectations, we exclude enough results to match expectations or reword our expectations to imply the results were expected all along.

6)  Viola!!  Future climate change can now be predicted.

Answer 2

We assert in the philosophy of science that theories are useful insofar as they allow us to anticipate results.

But anticipating results has to start with knowing the inputs to the system as they will occur. We do not expect a machine's designer will be able to tell us what it will do until we describe what we will do with it. She can only say to us, if this machine has the following situation, it will do the following.

If we know that a major chain of volcanoes erupting has had colossal weather impacts, and you want to tell what the weather will be like, at least specify whether there will be major volcanic activity... same for a whole lot of other causative agents.

By the time you have specified all the constraints, of course you will have defined an entirely improbable situation.

Our models can at best anticipate the general effect of modifying a few parameters, They can not anticipate whether those parameters will be modified.

Answer 3

Simple - YES!!!! All kind of global scientist out there, several are debunking Al Gore's theories now, plus in So Cal, you see the smog detector's and environment on the freeways, satellites, etc.

Answer 4

Make it so water is frozen or in a vapor form, we are in between., not AT one or the other.  One must realize that there is no norm or set point, it changes, just as the continents move.

Answer 5

It's hard to give you an answer since no current models can predict what the climate will be in the future, in fact it's hard to predict what the weather will be next week. The  Earth is big, the air, the land and the oceans all interact in so many complex and ill-understood ways that it's all but impossible to make long-term predictions. Maybe in the future we'll be able to, but all current models have failed miserably for a variety of reasons, mostly because they can't include and consider all the variables.

If it gets warmer, the Earth will get greener, overall, that's my prediction. If it gets cooler, it will be whiter due to snowfall. I'm not being facetious, it's just not possible to 'model future changes' today.

If this is for homework you could try posting it in that area instead but I assume your teacher will want you to say to rely on the UN's IPCC models, which are as good or bad as any.

Answer 6

Spend billions of other peoples money, Like all Govt. buildings are.

Answer 7

I'm not sure we can with any accuracy.  One problem is how do we weight the parameters.  That starts with a lot of prejudice and ends with intentionally distorted results.  

Another problem is that there are so many elements involved, and such complex interactions, tying it all together into a reasonable representation becomes nearly impossible.

Finally, some of the most critical elements, like the sun's activity, and some wind and water currents, are unpredictable, .
