It's almost been a double El Nino -- no La Nina in between.
Bad news for AUS. Generally means even less rainfall in ag areas.
As we know, EN/LN are phenomena associated with the sea surf temps
in the tropical east Pacific. So we'd expect there is an association
with overall increasing global temps.
I've posted data on this before. But -- nachly -- we expected the /D\ullards
in the audience to have "forgotten" (aka not even gotten past their
eye filters) anything like this.
We can look at what fraction of months have been spent in +ve ENSO
territory. 3m with an ENSO index above .5 is an official El Nino some places
(other places have more conditions, e.g. the Aussie BoM).
If we plot atm CO2 against the percent of months in each year
with a positive ENSO value we get:
(lag 3 years)
y = 0.0038534*x + -0.773274
beta = 0.0038534 +- 0.00140392 90% CI
T-test: P(beta>0.000000) = 0.999973
r2 = 0.403161
calculated Spearman corr = 0.530023
Critical Spearman = 0.432000 2-sided; at 1%; reject H0:not_connected
IOW there is strong statistical evidence that El Ninos are more likely
as CO2 levels increase. The proportion of months in +ve ENSO phase
increases by 38% for each 100 ppmv of additional CO2 in the atm.
The T-test and Spearman test both put this like at better than 99% likely.
The R2 shows that 40% of the annual variation in this fraction of +ve ENSO
months followes similar variations in atm CO2. I.e. CO2 is likely
one of 2 or 3 factors that fully explain El Nino development post 1950
(when accurate ENSO data series begin).
