trees in the arctic

[Helions]

when someone thinks of the arctic, they usually think of vast lands of ice and snow...now with global warming messing up the world's climate, trees have started to take root in the arctic...

tree takeover in arctic

If you ask me, that sounds like good news. Well, maybe the animals will have to adapt to different habitats, but more trees is always good. Right?

[Harlequin]

Not always. More trees = more oxygen and less CO2 but more trees in the arctic is a bad thing.

 

The trees will confuse animals and will invade local plant-life. Many plants are found in the tundra and only there, and this is why warmer arctic isn't a good thing.

 

So, it's not really the trees that are the problem, it;s the climate. The trees are just a secondary thing.

The amount of temperature change in the arctic recently is insane. Usually, a person would die from the cold if they went in the water, but now someone's actually swum a full kilometer in it. I know its the Antarctic that we should be more worried about, but its all symptoms of the same problem, and its pretty scary imo.

Y'know, global warming itself only accounts for 1 degree celcius of warmth. You realise that that one degree isn't going to magically make trees appear, especially since it's very many degrees under the freezing point in the artic. Southern winds or warm currents would make much more sense, but oh no, let's not listen to that. Blame it all on human-induced global warming. Yep.

I can see 1 degree being enough for tree growth. It's not ALWAYS snowy in the arctic, and as the article says, the tree problem isn't just that its too hot, its that its "summery" arctic temperature for longer. Obviously we don't have trees sprouting at the North Pole in December, but tree-friendly territory is spreading, the glaciers are melting and the grizzlies are taking over polar bear territory.

 

so if its not caused by global warming, then what?

The answer's in the edit. You posted before I was done.

Extraordinary i never would of thought that a tree(s) would grow there!!

[Harlequin]

Poor polar bears, I say. If grizzlies intrude on their territory much more there'll be rampant hybridization.

Regardless of who is doing it (Nature/Man), 1 degree celcius can have a large effect on water levels due to thermal expansion.

[Demi:Pulse]

Indeed, and it's only going to expand more as life goes on.

:wub:But if trees grows there then they need co2 for this you need factories for this you need land but when the ice melts then theres no land so whats going to happen?
