The Point is this, With short residency time and multiple sinks that are sucking up the CO2, there has been no warming for almost 19 years and the increase is not causing a response of increased temperature. The CO2 - Water Vapor positive forcing link does not exist by empirical observed evidence. The AGW most critical hypothesis fails empirical review.
Remember when I started out on this forum, you showed took troposphere data in a vacuum and then CO2 in a vacuum. What's wrong with adding cubes up all over the earth that have all the temperature differences measured, and then solving? It seems you're looking in a vacuum again. The CO2 residency times acceleratingly get worse as the Ocean gets stuck up.
I'll let Crick argue that our spike is steeper because I think he/she will win. I should probably move on from this thread soon.
Our current spike is less than 100 years long. The resolution of 10,000 year averages in the record would mean our current spike would never be seen until it reaches 8,000 plus years in length above the highest point of the overall average.
What this mean to you is this, the record is not clear enough to rule out previous spikes of this magnitude from happening naturally. And as others have posted on this forum, there are other proxies out there which show much greater resolution and the fact that these spikes are not unprecedented or outside of natural variation. You simply do not have the resolution to back up your assertion.
The current "spike" is still accelerating. It could not possibly turn around for at least a couple of centuries. And NO ONE has ever come up with a natural mechanism that could cause a spike that quick. There has been nothing like the current conditions since the Permian Triassic extinction.
