A climate trivia:

[nova]

There's been lots of discussions of the warming climate.

If climate warms enough, the consequence will be a dramatic reduction of the temperature of the climate.

Why?

the climate has a history of warm then cold then warm then cold..

you could have said 'if the earth cools enough then it will warm'

You're probably right, but if we're not getting into history. If we're thinking of now, the present time.

- Climate warms
- Ice from the north continues to melt with increased speed.
- More rains (Warmer air consists more humidity)

All this affects to one important thing.
Where all this water is going to and what it lacks.

I don't understand that, I'm by no means a specialist of this, but if you could explain that I'd appreciate it

Weather patterns are tied to the major sea currents. The observation is that increased melting at the poles is changing those currents. You may notice this in Finland if warm wintertime currents shift, and the full brunt of arctic winter winds is no longer tempered by these currents.

The planet, like a refrigeration system, functions in equilibrium. If one thing changes, values shift throughout the system until a new equilibrium point settles in. There are so many unknown variables with weather and climate that we are only beginning to understand these relationships.

In California where we get all our rain in 3 months and nothing more for the remaining nine, the Sierra snowpack level appears in the paper every day. Our major concern with global warming is with floods and droughts. A couple of degrees of warmer weather and our rivers flood in the spring and run dry in the summer.

hey there ....
how are u all
this is my first post from a long time
anyway let me get into the discusion ....
Warmer climate results in a colder one why ?
Warmer climate will make the icebergs melt and the water of the seas evaporates , more vapor and inpurities in the atmospher equals that the sun tempreture will not arrive to the surface of the earth as it was arriving equals low earth tempreture and formation of ice again .. ... so the water vapor and impurities in the atmospher will be like a curtain stopping the heat coming from the sun to attend the earth .

That's my point of view

That is so true. But not the answer for the trivia

Let's make this more tasty; The Salt!

Ok perhaps I'm taking this too far. Let's just say: The Gulf Stream.

botrous, very good explanation, but not the answer

boutrous, my best regards to Lebanon! I was there for an year (UN). Very nice country with very nice people!

you were being a little to 'local' in your question.

Whilst we in the northern hemisphere (particulary N europe) will get much colder if the gulf stream shuts down other parts of the globe may continue to rise in temperature regardless......

Didn't realize this was a quiz. As I understand it, there is a very small probability of this. It would only occur if there was enough of a shift in ocean currents so that a severe northern winter driven by untempered arctic winds caused the snowline to move much closer to the equator.

Since most of the planet's land mass is in the northern hemisphere, too much sunlight being reflected back into space by the snow cover would cause planetary cooling. The effect could be cumulative from year to year until we all lose our jobs in refrigeration!

The melting glaciers at both poles are changing the salinity of the ocean and this seems to be affecting the ocean currents.

Isn't there something I read a while back about the opacity of the atmosphere effecting the amount of sunlight reaching earth.
If we clean up our particulate emissions then global warming accelerates.
Please tell me if I'm 'in the clouds', so to speak with this one.

[rbartlett]

no you're not.

studies has shown that the soot deposits in the upper atmosphere has reduced tha amount of sunlight reaching the surface by approx 15%

http://www.sfgate.com/cgi-bin/articl...NG6E6KL7C1.DTL

they are now supposdly scared that the reduction in soot emmissions -kyoto et al- will cause the missing 15% to accelerate global warming

cheers

Has anyone here in the UK noticed that since Kyoto has been signed our winter has returned.

Now, if someone can arrange a similar agreement for the summer months all will be well.

[billyfridge]

I've noticed that Brian....we'll see what kind of summer we have.
when i was a kid in the fifties the winters were much the same as this year perhaps a little more snow...there was a lot of air pollution then...

Hi guys

It is difficult to find out what will happen wiht the cilamate in the future, but here is a link to a book (Not by fire but by ice).

Hi Guys

This trivia has nothing to do with the sunlight (of course it’ll affect)

This is what (according to scientists) will happen:

Gulf Stream delivers huge amount of the heat to the northern hemisphere <= EDIT: This is a fact, not a part of the global warming.

- climate warms up
- melting of the Nordic ice will increase
- ice from the north contains very little salt
- melting ice reduces the salinity of the water of the northern Atlantic
- Gulf Stream relies on the salt; Warm Gulf Stream cools down while it's traveling to northern hemisphere. Cool (salty) water will sink down and flow back to south. This is a huge "conveyor belt of the heat" which continues day after day. Gulf Stream contains 1.000.000 nuclear power plant's heating capacity and it moves the whole world's raining quantity of the year in a one single second.
Now if we melt the ice enough, it'll cause the Gulf Stream to stop (because saltless water will not sink down (salty water is heavier than less salty)) and that will cause a very cold climate to northern hemisphere. The first one to affect will be the UK. According to most pessimistic scientists, this will occur within 50 years.

Here was stated that my trivia is too northern related. Well you’re wrong.
If you think about the world in longitude scale, we’ve had the most rains in certain longitude (the rain forests). Now if the climate cools down in northern hemisphere, it’ll push the rains to more south. Think about what happens to rain forest if there's no more rains and how will that affect to the rest of the world...

This makes sense, no?
