The Meteorological Office, Britain’s equivalent of our Weather Service, has a great short article that refutes the notion that global warming has slowed down. The key paragraph is the first one:
"Anyone who thinks global warming has stopped has their head in the sand. The evidence is clear – the long-term trend in global temperatures is rising, and humans are largely responsible for this rise. Global warming does not mean that each year will be warmer than the last, natural phenomena will mean that some years will be much warmer and others cooler. You only need to look at 1998 to see a record-breaking warm year caused by a very strong El Niño. In the last couple of years, the underlying warming is partially masked caused by a strong La Niña. Despite this, 11 of the last 13 years are the warmest ever recorded."
This figure is also quite helpful
Global average temperature anomaly 1975-2007
Global average temperature anomaly from 1975 to 2007, relative to the 1961-1990 average.
The black line shows the annual figure. The red line shows the trend over the full 33 years.
The blue lines show the varying rate of the trend over 10-year periods.
