This may be well known to those who follow solar activity closely, but
this summary of a new paper on recent sunspot activity on The Register

The regression line looks too steep to my eye though I dare say that's
an optical illusion and it's been calculated accurately enough. But

*From selective data.
The Register is not entirely reliable where denying AGW is concerned.

It is just about possible that the solar magnetic field is weakening
longer term and that could lead to no visible sunspots at all if it
falls too low, but it is far from certain. We are just on the rise of
sunspot activity at the moment and although this cycle is predicted to
be lower than the last one it is a long way from vanishing altogether.

If we do enter a new cooler Maunder minimum it might buy us some time....

even so the regression line looks fairly sensitive and another year
with higher than expected sunspot activity might well lower the slope..

It almost certainly will.

I agree that if it happened, it might buy us time; no more. Although
the solar minimum between solar cycle 23 and solar cycle 24 was the
longest for over a century, we saw no cooling whatsoever. Indeed we
saw record global temperatures at the end of the extended solar
minimum in 2010 - year which also saw 6 months of La nina conditions
as well. The warming trend just appears to have overriden any possible
cooling from the theoretical increase in cosmic ray activity
(producing more clouds via more condensation nucei being created) or
from the reduced solar output.- Hide quoted text -

Blimey how ironic the AGW people will praising the nasty big oil
companies for letting the human population buy and use their product
and release C02 into the atmosphere.

Let's turn this on its head and say that Co2 might buy us time. As for
the "we've seen no cooling yet-despite" this is sensational and
worrying news, unless the empirical observations that started in 1603
of Suns spots disappearing and coinciding with a life shortening
severe cold spell is wrong-then we should be glad of Co2 and any
warming effect it may have,


For Nasa to now come out and admit that all is not going to forecast
and conceded that the sun trumps C02 everytime, is big news indeed.
