Conclusions

“Coverage bias signficantly impacts recent temperature trends. The
methods used here to estimate and correct for that bias are rudimentary, but
present a coherent picture of continued warming. It is striking that three
different approaches, when applied to either the HadCRUT3 or NCDC data, yield a
record which is very similar to GISTEMP. The same approaches applied to the
HadCRUT4 data lead to a greater warming trend owing to the inclusion of the HadSST3
bias corrections.

Taking into account the effect of the El Nino cycle on recent trends,
the warming rate of the largest cluster of datasets is consistent with longer
term trends. If the HadSST3 adjustments are also correct, the underlying
warming rate probably exceeds 0.2°C/decade. There are still known cool biases
in each of these time series.

We have not taken any account the impact of a possible
increase in aerosol cooling. This raises the worrying possibility that the
underlying warming rate has been accelerating, and has been masked by aerosol
emissions and the biases in the temperature series. Further developements on
SST adjustments and aerosol impacts will hopefully clarify the situation.”

It just keeps on keeping on as we watch and know that very little, and nothing effective,
is being done about it.  Ecocide is a good word for it.
