The El Nino has been fairly short-lived and has been moderate. See how

for over a century), if solar really is a driver of our present
climate, we should see a rapid decrease in temperatures. The PDO
cycle, being negative, should reinforce that and we ought to see
global temperatures returning towards the 150-year mean........if no
other factor is involved.

PDO has been positive this year but I suppose it might go negative as La
Nina gets going.

Yes I know, but the great PDO powers that be have designated a
negative cycle, even though the cycles do appear to have broken down
since 1998 and the PDO has been largely positive since August of last
year. However, Roy Spencer and some others are convinced this negative
cycle is controlling our planet's weather. I'm very sceptical of that
being the case, myself. Although the El Nino has been declining, the
PDO hasn't shown any recent signs of turning negative, but I agree
that it might and the positive PDO may have been due to El Nino.
