UAH Update – May 2016

June 2, 2016

By Paul Homewood 




UAH numbers are now out for May, and show another big drop, down from 0.71C in April to O.55C.

Although they peaked higher than the 1997/98 event, UAH temperature anomalies have dropped below for the last two months, and are now virtually back to January’s numbers.





In 1998, temperatures remained high through to October, but SSTs have plunged in the Equatorial Pacific in the last three months and there is a massive pool of colder water just below the surface.




In simple terms, there is no more warm water left to feed air temperatures, so we are likely to see temperatures continuing to drop for the next few months.

Because of time lags, if La Nina conditions do arrive by late summer/early autumn as most models are predicting, we won’t see the full effect on global temperatures until the end of the year.

    Don’t worry, by the time temperatures fall the past will have been downjusted so much it’ll still be hot.

    When do you think the anomaly will reach zero ?

    Sept. Oct. Nov or Dec?

    How can this year be warmer than any other year? We’ve still got snowstorms all over the globe. Central US has had some of its coolest pre-summers in decades. Rockies are still getting snow storms. This data makes no sense to me. Are they heavily biasing the data out of India?

    La Nina and its effects are on the way, but I am not sure about how ‘strong’ it will be. The latest sub sea anomaly section from BOM shows quite a reduction in the volume of cooler water:-

    Will it continue to fade or could it get stronger later? Nobody knows, as always time will tell.
