The primary goal of this site is to provide mature, meaningful discussion about the Vancouver Canucks. However, we all need a break some time so this forum is basically for anything off-topic, off the wall, or to just get something off your chest! This forum is named after poster Creeper, who passed away in July of 2011 and was a long time member of the Canucks message board community.
We know human activities are driving the increase in CO2 concentrations because atmospheric CO2 contains information about its source. Scientists can tease apart how much CO2 comes from natural sources, and how much comes from combusted fossil fuel sources.
Compared to other carbon sources, carbon from fossil fuels has a distinctly different “signature,” essentially the relative amount of heavier or lighter atoms of carbon (technically δ13C). The more negative the δ13C, the higher the proportion of carbon from fossil fuels.
Over the years, δ13C has decreased while the overall amount of CO2 has increased. This information tells scientists that fossil fuel emissions are the largest contributor of CO2 concentrations since the pre-industrial era.
Yes yes, human activities are driving the increase in CO2 concentrations.
The question is how much effect does increasing in CO2 concentrations have on global warming...

Climate change has been ongoing for over 4.6 billion years. The catastrophic events in earths history are due to geologic and or cosmic events. Species have come and gone. Mass extinctions have occurred. Earth kept rolling along as did life on Earth. To think our insignificant species can have a lasting effect is to be on the arrogant side of the debate.
Straw man. No-one is trying to make a lasting effect in terms of millenia. For the most part people are thinking of the immediate future, i.e. their kids and grandkids.
Princely the shortsighted arrogant belief that natural processes can be reversed in order to perpetuate a species in stasis.
The nice thing about natural processes is that they are very slow, giving mankind time to adapt. It's an acceleration of the change that we want to avoid.
Mass extinctions like the K/T boundary didn't happen in an instant, except in geological time, an instant.
Not relevant to a climate change discussion. Unless, of course, you are saying that despite mankind's ability to adapt in geological time to non-anthropogenic climate change, it's pointless since we'll probably be obliterated by an asteriod anyways.
You are beginning to understand, though our species entered a state of stasis long ago and has been more concerned with manipulating the environment to avoid the inevitable extinction. The period of adaptability is for the most part, gone.
So you're basically a nihilist. Sorry I don't share that view. Even if I knew that in 200 years our planet would be hit by an asteroid, I'd still be concerned about human-caused climate change for the sake of my own kids' futures.

He's not "a suspected rapist" and Blasey Ford is a hardcore political activist mounting a smear campaign, nothing more.
The Dems are desperate and they will fail... again.
You must be so proud.
There is an allegation and until it’s proven to be true or false how can kavanaugh sit as a Supreme Court judge?
The answer is he can’t. If a teacher was accused even falsely he would be on leave until it’s sorted out.
Well done, no doubt this is the exact reasoning some folks would use before throwing down a false accusation.
Wait until the last possible moment in proceedings and then lay down a false accusation = stall tactics.
And of course smear campaigns against one's perceived enemy have their own rewards.
I call this dirty politics...
Ha when was politics anything else ??
Tell me if the shoe was on the other foot, the republicans wouldn’t be howling with rage ?
Poor old Bill, all he got was a willing hummer and they tried to impeach the guy...
Shoulda got a medal if you ask me, have you seen the Guys wife ??

Think of the world your grand parents or great grand parents faced. Do you believe you can predict the world your grand children and great grand children will face?
Over the Internet, you can pretend to be anyone or anything.
I'm amazed that so many people choose to be complete twats.

Utopia or smashed by a asteroid, it doesn't matter. We make decisions based on the knowledge we have now.
A company I used to work for hired an Ivy league tectonics guru to do a Cretaceous reconstruction of the Americas. He and a phd student worked on it for over a year and presented their research. One of the many interesting things in their work was the correlation of tectonic rates to sea levels. Speed up mid ocean spreading rate and the sea level drops, slow it down or increase subduction rates and sea levels drop.

Hey Doc two more women coming forward, that’s three accusations now...
I guess you would call that piling on.
But increasingly it looks like where there is smoke.
However aside from all this it’s deeply troubling that the Supreme Court is being stacked with right wing fanatic Christians. I kinda thought the idea of having a panel of judges was to make the court more balanced.
However it seems that the court is a playground for republican politics and a sinister ploy for suckering votes.
