...to continuing record high temperature readings from the UAH satellite. Specifically, I asked him when we might know the result of this "short term test" of Roy Spencer's hypothesis (vs.the IPCC's, read through link). He responded::
Thanks for alerting me to your weblog. I contacted them [UAH], and they reported there is a drift in the part of the diurnal cycle that the AMSU sensor samples. I have urged them to write a weblog on this issue to clarify as all of us are comparing with their long term average.
In the July analyses of UAH and RSS (which is from a different set of satellites without the drift) we will see if this record warm anomaly appears. I have been informed that since 1992, the RSS and UAH data closely agree with each other. The differences that do occur provide us with a measure of the uncertainty in the assessment of these climate metrics.
All of us should follow this data closely (along with the upper ocean heat data) as I feel a much better consensus can be achieved if we focus on this information, rather than the use of a global average surface temperature trend to assess global warming.
On the two hypotheses, however, we need to go through the current El Nino to see if the heat remains elevated or returns to a long term average. The upper ocean heat data will also be key in this assessment.
Given the other side of El Nino: some time in 2010 or 2011.
