I’ve moved to WordPress. This post can now be found at March 2009 Mid-Month ENSO Update
################During the week centered on Wednesday March 11, 2009, NINO3.4 SST anomalies have risen above the threshold for a La Nina to -0.41 deg C.

On the other hand, NINO3 SST anomalies have dropped to -0.84 deg C.

The cool water appears to be working its way westward toward the NINO3.4 region. Refer to the following map…

To add another perspective, the Southern Oscillation Index (SOI) for February 2009 shows no sign of weakening. Note that the SOI data has been inverted so that it corresponds to the variations in NINO SST anomalies.

Nothing has done more to "GREEN" the planet over the last several decades than elevated levels of CO2 together with moderate sun driven warming. Studies show doubling CO2 levels increases plant growth rates 33 percent. It is no accident commercial greenhouse operators invest heavily in CO2 generators to increase the productivity of their operations. Farmers, ranchers and foresters, and in fact all living things, have benefited from this rare, but temporary, gift of nature. Why is our government spending so many resources to convince us otherwise?
