Nature says global warming is real

http://news.discovery.com/earth/global-warming/trees-invade-arctic-tundra-130311.htm


There it is, nature is warming up where the artic is now supporting trees where trees should not grow. This is indisputable evidence, nature is telling us the earth is warming.

 

No matter the evidence, deniers of AGW will deny the evidence. Its as simple as that.

 

How does that prove man made global warming ?

 

Well when you come up with your model that shows mankind had no impact, you can make your point, but so far the evidence points to mankind.

 

You failed to show how tree growth proves man made global warming , and your personal attack shows that you can't .

lol thats not how burden of proof works buddy boy.

 

Do you really think humans can keep pumping CO2 in the atmosphere while cutting down forests w/o any negative consequences?

 

Can you not show how tree growth proves man made global warming ? White flag?

 

A question to a question is not an answer.

Do you really think humans can keep pumping CO2 in the atmosphere while cutting down forests w/o any negative consequences?

 

Man produces carbon, trees like carbon, QED tree growing where trees never used to grow indicates trees appreciate man's gift of carbon

 

Ok. so you cant show tree growth proves man made global warming. White flag is noted.

Trees never grew there ? lol...... educate yourself.

 

So you dispute the article that in places where tress did not grow out on the Tundra.....trees are now growing?

 

I dont care whether tree`s are growing there and why would I dispute it? I am simply asking how that proves man made global warming? Tree`s grew there before, something you seemed not to know. Maybe you did know it and I am just mistaken?

 

Yes, nature has a funny way of changing over its 4.6 billion years on Earth. Oh, by the way, nature is going through another warming period just like it did for billions of years. So, what is your point?

 

When did trees grow there before, who's evidence are you using. The data from the same scientists that have been doing all the climate research. Or was is so far back that mankind didn't even exist. Here is the indisputable evidence of warming, yet you try to dismiss it as nothing.

 

When the Continents were in a Pangaea formation ( and probably multiple other times in our 4.5 billion year history of earth). I just read your thread , and your link, and dont see how it proves man made global warming. Sorry broseph.

 

even if your statement was true; so what of it? Will the earth disappear? Why the hysterics?

I don't know how you plan on stopping cyclical climate changes. The earth has been going through that for millions of years.

Wasn't Greenland once green?

I'm tired of the cold in FL this winter and a little global warming would be much appreciated

So when that land area wasn't in the artic, it had trees. I will give you a second shot at it.

 

So what of it, means you haven’t thought this through for the possible consequences of global warming. Perhaps you should research it.

 

So as the globe warms trees which are CO2 sinks expand their range.

Well there is another negative feedback that the models don't include.

 

Who decides where trees should or should not grow?

 

Why would it matter if mankind didn't exist?

 

Who denies that we are in an interglacial and have been for quite some time?

Trees have been expanding their northern range since the interglacial began.

 

Nature does. A place called the tundra, was so named, because it was so cold, little plant life could survive there. If you want I can link in a reference.

That is part of the argument now, so yes it would matter.

Why don't you submit the evidence to LiveScience instead of making arbitrary statements.

 

Because no other animal is pumping CO2 in the atmosphere like humans do and cutting down forests like humans do.

 

So nature's response is to allow trees to grow somewhere else... I fail to see the problem...
