Spectacular Drop In Global Average Satellite Temperatures

UAH Global Temperature Update for June 2016: +0.34 deg. C

NOTE: This is the fifteenth monthly update with our new Version 6.0 dataset. Differences versus the old Version 5.6 dataset are discussed here. Note we are now at “beta5” for Version 6, and the paper describing the methodology is still in peer review.

The Version 6.0 global average lower tropospheric temperature (LT) anomaly for June, 2016 is +0.34 deg. C, down 0.21 deg. C from the May value of +0.55 deg. C (click for full size version):

This gives a 2-month temperature fall of -0.37 deg. C, which is the second largest in the 37+ year satellite record…the largest was -0.43 deg. C in Feb. 1988.

In the tropics, there was a record fast 2-month cooling of -0.56 deg. C, just edging out -0.55 deg. C in June 1998 (also an El Nino weakening year).

The global, hemispheric, and tropical LT anomalies from the 30-year (1981-2010) average for the last 18 months are:

2016 02 +0.83 +1.17 +0.50 +0.99
2016 03 +0.73 +0.94 +0.52 +1.09
2016 04 +0.71 +0.85 +0.58 +0.94
2016 05 +0.55 +0.65 +0.44 +0.72
2016 06 +0.34 +0.51 +0.17 +0.38

The rapid cooling is from the weakening El Nino and approaching La Nina conditions by mid-summer or early fall.

As promised just over a week ago, here’s how we are now progressing toward a record warm year in the satellite data:

dataset 2

The June anomaly is well below the dashed red line which represents the average cooling rate required for the rest of 2016 to tie 1998 as the warmest year in the satellite record. So far my prediction that 2016 will end up being a new record warm year is not shaping up too well…the cooling we are seeing in the troposphere really is spectacular. Just remember, the temperature anomaly can also temporarily rebound for a month, as it did in late 1998.
