NASA GISS has the Summer global temp. data online now. August 2009 was the Second warmest on record globally. The Northern Hemisphere meteorological summer of 2009 was the third warmest on record. Only 1998 was warmer. The reason 1998 was so warm is easily explained. The Pacific ocean was incredibly warm that year. The reason? The greatest El Nino event on record.
That much warm water heated the surface temperature of the entire planet. The warmth over the tropical pacific, caused the jet stream to blow faster from west to east. This, in turn, slowed the rotation of the planet! The days were actually a few thousands of a second longer in 1998!
Some of these junk science sites use 1998 to claim that the planet is cooling. They start their graphs in 1998 and yell global cooling. Doctor Mark Serreze of NOAA’s National Snow and Ice Data Center (NSIDC) said it best. Amazing ignorance. I wrote about El Nino earlier in the summer in this space.
One more picture. The great melt in the Arctic. I spotted it on the One Blue Marble blog. It was taken by Michael Nolan a well known environmental speaker.
