A new report has indicated that 2007 has been the second warmest year on record since 1880, with a global average of 14.73 degrees Celsius (58.5 degrees Fahrenheit).

The report, issued by the Earth Policy Institute, has stated that the year 2007 fits into a pattern of steadily increasing global temperature, with the eight warmest years on record all occurring in the last decade.

This can't be true. Isn't global warming supposed to have stopped a few years ago (according to some)?

Nice link, I knew drinking bottled water was was stupid, I didn't know it was evil!
God bless the Earth policy Institute, you're going to save us from ourselves

Data collected from around the globe indicate that 2007 ranks as the second-warmest year on record, according to a new analysis from climatologists at NASA's Goddard Institute for Space Studies.

Everything else I've seen states that 1961 to 1990 is used as a baseline average.The one in this link is 1951 to 1980. I'd have thought that everybody would be using the same baseline, is this not true?

Check your 'base line'. These are not always the same!

Blame the 'weather men' for this.

That baseline merely determines what is taken to be the average temperature so that they can say such and such a year was however many degrees above average or below average. Whatever is used as a baseline has no bearing on the rankings of the warmest years on record.

If there were no climate change you would have expected 2007 to be cooler than the average due to things like the La Nina effect and it being a minimum in the 11 year solar cycle.

And a corollary would be that years between 1998 (El Nino) and 2007 (La Nina) would be warmer than 2007 without additional CO2 and with additional CO2 even more warm between 1998 and 2007. So what else is going on?

There is lots going on all the time - remember this is the temperature of the land and ocean surface only. For example, ocean currents have recently cooled the southern ocean surface temperatures. In addition you have the error bars which I guess are mainly sampling error. Eg. is last year's warming of the arctic fully represented in the figures...? I don't know. I think this is why NASA and HadCRU always disagree a bit.
