‘Of these anomalies, one of the most recent to be discovered takes place in the Indo-Pacific warm pool. This body of water, which spans the western waters of the equatorial Pacific to the eastern Indian Ocean, holds the warmest seawaters in the world. Scientists found that, over a period of roughly two decades, the warm pool’s average annual temperatures and dimensions increase and then decrease like a slowly pulsating beacon.
The effects and origins of these oscillating waters, however, remain something of a mystery. For the past three years researchers based at NASA’s Goddard Space Flight Center, led by atmospheric scientist Vikram Mehta, have been trying to unravel some of the questions surrounding the warm pool. They have been poring over atmospheric and sea surface temperature data from the western Pacific to the eastern United States looking for answers as to why the warm pool oscillates and what effects this oscillation may have on the world’s climate. What they found is that the warm pool’s vacillations may be felt as far away as Arkansas and may be powerful enough to broaden the extent of El Niño.’

It is doubtful that even recent warming (1976 to 1998) can be distinguished against natural variability. The attempts to do so rely not merely on not knowing what the global energy dynamic at top of atmosphere is but of actively discounting – when it is not convenient – the available satellite data. Convenient is the brightness models of Harries and others – inconvenient is the ERBS edition 3.
