Hi,

Can somebody please provide a source of information confirming a change to summer shipping lanes.

My farther is convinced global warming is BS so i need some evidence otherwise (just to fire up some debate between us!).

Can anybody provide brief factual information that at least shows the summer shipping lanes have opened up bacause ice is melting sooner in the year?

Need to be fact not opinion... not even opinion presented as fact (very common!).

Cheers.
 
I don't see how people can deny Global Warming is BS when you see it in front of your eyes everyday. May be they need their garden flooded before they realise how serious it is.
 
Yup. Global Warming is pretty much agreed as fact. It's what's causing it that is open to debate (natural, man-made, or both).
 
Would it be classed as global warming if it was merely part of a cycle?

I've read (and partly agreed) a couple of white papers on the subject. One was the opinion that, although we're probably speeding up the process, the climate shift is part of a cyclical process that would happen with zero human intervention.
 
OK just need some very simple hard fact, if possible, not huge reels of text!

Then we will take it from there...

I also am not convinced our society is the cause, but i'm going into it further than i should be right now. At the moment i just want solid proof the ice sheet or whatever, is melting sooner in the summer. i.e. shipping lanes.
 
There are people who think that GM is natural i.e. it's just a normal fluctuation in the Earth's cycles. Others believe that either man has brought on the GM or that we're speeding it up because we're dumping more of the warming gases into the atmosphere than ever before. The sensible conclusion from all this is, obviously we don't know but it seems pretty sensible to conclude that adding more of these gases will only increase the likelyhood of GM.

I believe that humans may not be directly responsible as indeed it may be part of the Earth cycle but all the increased human activity since the industrial revolution cannot simply be passed off as trivial, it will be having an affect at some level - direct or indirect.

There are also counter-theories against GM, saying that the emission of the particulate matter with the gases is infact protecting or shielding the surface from more of the sun's radiation because they're bonding with the cloud cover.
 
"Over the past century, average near-surface global temperatures have risen by 0.7°C."

OK this is apparently FACT.

... i hate to suggest we could not accurately measter temperature of near-surface temp in 1906.
 
Therein lies the problem, its difficult to substantiate it in simple terms due to the past inability of taking accurate recordings.
 
Just a quick question: The name is on the tip of my tongue atm, but I can't quite remember it and it's bothering me :p

What's the process called when the sunlight radiates off the snow, it bounces back?

Surface reflectivity is a large factor in the global climate, but I'm not thinking thats the term you're after.

Surface reflectivity pertains to the amount of light bounced back from the earth's surface from the likes of ice caps, desert, etc.

Now thats more like it.

It's always fun presenting this issue to my farther. He always calls BS. He has that backing of a friend (who helped develop radar for the navy, yes... to say he's intellegent would be a gross understatement.)

Yes that's what I mean, but there is a specific term for it and I can't quite recall it.
