Global Warming: Plateaued?

No! Global temperatures have not
risen as rapidly as they did in the previous two decades, but the world
is still getting warmer due to man made emissions. 9 of the 10 warmest
years on record have occurred since 1998. 
Overall, the world has warmed by 1.4°F.

What has tempered the rate of increase is that the
deep ocean waters below 2300 feet have heated up since the year 2000,
even as the temperature of surface seawater has remained stable. Warming
over the last decade has been hidden below the ocean surface.
the sun has not been shining as brightly. Over an average of 11 years,
the sun's energy output rises and falls, subtly influencing Earth's
climate. The last solar maximum occurred in 2000; since then a prolonged
solar minimum has kept the sun dimmer than usual.
Another cause is
due to an increasing influx of sunlight
blocking particles into the stratosphere -- vast quantities of
pollution from coal burning China and several mid-sized volcanic
eruptions. These particles work in the opposite way to greenhouse gases,
reflecting solar radiation away from the Earth.
