Reverse Climate Change?

You should probably take a look at what the effect of almost 2 trillion tons of CO2 will do when our arctic regions permafrost continues to decline... To put that into perspective, that would be like doubling our current carbon levels in the Atmosphere which is already very high.
Now... Just like your NASA youtube video describes... A large portion of the earth becoming greener is actually in the arctic regions, that is far from being a good thing, due to the above.

Compared to the rest of Earth's history, doubling our current CO2 levels is still only a fraction of when life was still sustainable at peak CO2 levels ... 

Actually, it's a good thing that the arctic region is getting warmer since greening indicates more arable land to use! With the arctic getting warmer it opens up the two biggest countries such as Canada and Russia to farming and inhabitation ...

In places like Australia... And I am speaking as a firefighter... More greening isn't actually a good thing... That means fuel loads will be higher and drier in our intense summers, flora that has adapted to the current conditions will decline and invasive species will be more likely to take over... And that means our fauna will also be impacted.
Again. Not a good thing.

I don't know enough about Australia to make an educated comment on it so I'll leave this statement as is ...

Greenhouse has a cascading, accelerated effect.

The other issue is... Even just 1-2'C of warming can have a devastating effect, Oceans hold a significant amount of dissolved CO2... And as they warm, they release more CO2, so CO2 levels will continue to accelerate.

@Bold Highly dependent on the conditions. In earth's case there's virtually no way to forseeably triggering a runaway greenhouse effect like in Venus's case since it's so much more closer to the sun and had a very thick atmosphere (at least 100x more than earth's) to begin with ... 

There's no need to continue fear mongering doom and gloom about the survival of human species because of a 1-2 degree celsius increase. It's been physically checked out to be implausible ... 

More pressing issues to worry about in our lifetimes and very likely the next 10 generations lifetimes than climate change ...

As for my statement about "hundreds of years". - We have increased CO2 levels from 280PPM to 400PM in around 100 years... And we have only continued to spew CO2 into the atmosphere at an exponential rate... What will happen in say... 500 years time?

Nothing because we'll run out of petrochemicals to burn before then ? So far we've only proven 100 years worth of economically recoverable coal reserves and 50-70 years of economically recoverable oil/shale reserves. It's only getting harder to find ways to recover fossil fuel reserves all the while the rest of the world is developing so energy consumption will also keep exponentially increasing ... 

Humanity won't be burning fossil fuels for a long time relative to their whole species existence. It'll be just a short stint ...
