I really do love Sinclair…

Here is a good video on the details.

Here are a few papers…

[1] From 1953 to 2006, Arctic sea ice extent at the end of
the melt season in September has declined sharply. All
models participating in the Intergovernmental Panel on
Climate Change Fourth Assessment Report (IPCC AR4)
show declining Arctic ice cover over this period. However,
depending on the time window for analysis, none or very
few individual model simulations show trends comparable
to observations. If the multi-model ensemble mean time
series provides a true representation of forced change by
greenhouse gas (GHG) loading, 33–38% of the observed
September trend from 1953–2006 is externally forced,
growing to 47–57% from 1979–2006. Given evidence that
as a group, the models underestimate the GHG response, the
externally forced component may be larger. While both
observed and modeled Antarctic winter trends are small,
comparisons for summer are confounded by generally poor
model performance. Citation: Stroeve, J., M. M. Holland,

And here is a quote that fits. From Benjamin Desraeli

We live in an age when to be young and to be indifferent can be no longer synonymous. We must prepare for the coming hour. The claims of the Future are represented by suffering millions; and the Youth of a Nation are the trustees of Posterity.
