It looks like the measurements are becoming yet
more refined. No new breakthroughs, yet, though.
Yes, it is already known (among solar physicists, anyway) that the variation
in the sun's energy output has far more impact on our climate than
the tiny increases of various chemicals. Eg. doubling the amount of
CO2 in our atmosphere has the effect (on our climate) as increasing
the solar irradiance by 0.1% more or less.
But the global warming issues are very complicated. See Hoyt's
work, for example:
Empirical Determinations of the Greenhouse Effect

The climate change that started in the 60s ended 5 decades of unusually
benign climate. Most long term climate "normals" were established in
the 60s by analysis of the first half of the 20th century - so as a
result there are often "100 year" storms, floods, droughts etc since
the statistical basis was unrepresentative of the more normal
natural variability. The message learned in the 1970s is still true,
that the main change is to more variability.
The scientists need to get past that '100-year' measurement bias, so
it looks like we are almost there to know clearly some long-term
solar effects.
