La Nina is Not Going Away. What Does This Mean for This Summer’s Weather?

by C. Mass, May 16, 2022 in WUWT


It is now clear that La Nina is not going away, and may hang around into next winter.  

Cold water is entrenched over the central and eastern tropical Pacific (the definition of La Nina) and the latest forecast model runs suggest a continuation into fall.

Several of you have asked:   what does this imply for our summer weather?

Let me tell you.

But first, the bottom line:   the summer effects of La Nina are modest, but will push the western side of our region towards cooler than normal conditions.

The Impacts

During La Nina years, sea surface temperatures off the West coast are usually cooler than normal, and those cooling effects spread inland.

To illustrate, here is the sea surface temperate difference from normal for the summer months (May through September) for La Nina years.    Blue colors are cooler than normal.

New Analysis Of Greenland’s GISP2 Temperatures Expose Selection Bias In Paleo Reconstructions

by K. Richard, Mar 17, 2022 in NoTricksZone


Scientists admit that 3 different Greenland Summit (GISP2) temperature reconstruction “strategies” produce 3 different paleoclimate temperature results. The reconstructions chosen as the most “robust” are therefore the ones that align best with the authors’ presuppositions.

In a new study published in Quaternary Science Reviews scientists (Döring and Luenberger, 2022) report they reject a reconstruction of Greenland Summit temperatures that shows it has cooled ~4°C since Roman times (shown below as the red trend line, extended to 2000 C.E.).

Greenland Sees Significant Snow, Ice Mass Loss Slowdown Over Past Decade, Danish Data Show

by P. Gosselin, Nov 14, 2021 in NoTricksZone


Data from the Danish Polar Portal shows Greenland ice melt slowing significantly over past 10 years. Increasingly rapid mass loss is a myth. 

German climate site Die kalte Sonne here looks at whether Greenland is really melting faster or not in its 78th climate and energy video (3rd segment).

Satellite measurement has allowed accurate measurements over the years and so reliable trends are detectable.

Greenland has added mass since July

Over the past year, since September 2020, Greenland has seen a number of heavy snowfalls, as depicted by the solid blue line in the chart by the Danish polarportal.dk:
