Oh No! Climate change might be natural?

Two separate studies through NASA confirm that since 2003, the world’s oceans have been losing heat. In the peak of the recent warming trend, 1998 actually ranked 2nd to 1934 as the warmest year on record.
John Willis, an oceanographer at NASA’s Jet Propulsion Lab, published his first report about the warming oceans. The article Correcting Ocean Cooling (see below) published on NASA’s Earth Observatory page this week discussed his and other results. willis used data from1993-2003 that showed the warm-up and followed the Global Warming Theory. In 2006, he co-piloted a follow-up study led by John Lyman at Pacific Marine Environmental Laboratory in Seattle that updated the time series for 2003-2005. Surprisingly, the ocean seemed to have cooled. He was surprised, and called it a ’speed bump’ on the way to global warming.
A second, independent study was conducted. Takmeng Wong and his colleagues at NASA’s Langley Research Center in Virginia came up with the same results. Wong studies net flux of solar energy at the top of our atmosphere. From the 1980s to 1990s his team noticed increased amounts net energy when comparing incoming solar energy to what Earth radiates and reflects. Since then, the solar flux has remained the same. Other studies have suggested that the sun’s output has decreased in the past few years.
