The pause that cools: No more warming until 2015?

You may recall the previous post where Basil Copeland and I looked at correlations between HadCRUT global temperature anomaly and sunspot numbers. This is similar, but looks at the Pacific Decadal Oscillation (PDO) and uses the same Hodrick-Prescott (HPT) filter as before on the HadCRUT global temperature anomaly data and the PDO Index. click for…

I hate it when that happens…

I was initially concerned that my stats were down this month, then I remembered that April has 30 days and March has 31. Of course there’s that nice spring weather, and I recall that TV station ratings suffer a drop during the spring since people are digging out from their winter igloos. But even though…

More on the PDO shift cited by NASA

For now, we have about 1 year of significant cold phase tendency in the Pacific Decadal Oscillation (PDO), here is the last 108 years of the PDO index, plotted from monthly values: Click for larger image – source Steven Hare, University of Washington Compared to the negative magnitudes seen from 1946 to 1977, our current…

NASA: PDO flip to cool phase confirmed – cooler times ahead for the West Coast?

What the modernized USHCN will look like

USHCN-M station at Greensboro, AL While I was at NCDC, Grant Goodge showed and provided me with a PowerPoint presentation about the plan to update the USHCN manual observing network to USHCN-M or “modernized”. In a nutshell, it is a “light” version of the Climate Reference Network. The summary of benefits goes like this. More Accurate Data…

Signs of the times

While I was on my week long road trip to survey weather stations and visit the National Climatic Data Center in Asheville, NC last week, I encountered lots of signs. Restaurant signs, road signs, signs from above, you name it. I think I must have passed 100 Bojangles restaurants and/or road signs. Bojangles is a popular…

Fun with Thermometers

A guest post by David Smith Recently I completed my tenth survey for Surfacestations.org. These surveys are fun, almost like treasure hunts where the clues are good but not always great, thus requiring some ingenuity. Also, the surveyor gets to see areas which may otherwise never be visited. And, they’re for a good cause. While I found…
