You may seen articles and stuff about a supposed 16 year pause in global warming. There's been all kinds of spin on both sides of the AGW debate. Here is my take:
Visually speaking, yes the global surface temperature in September was virtually the same as the global temperature in early 1997. Mathematically speaking, there is still a positive trend line between those two points, given all the monthly data points in between. I prefer the graph below created here.
Some would argue that the Global temperature is dominated by the oceans and in particular the ENSO. I would argue that natural variations, including oceanic oscillations, account for the majority of the changes we have seen.
