A recent paper by Mike Lockwood of the University of Southampton has claimed that over the last 20 years, solar influences on climate have declined, while Earth has warmed.

This paper is the latest in a rich tradition of near 20 years of IPCC inspired attempts to trivialize the solar/climate link.
There has been more than one rebuttal around the internet but I like Joe D’Aleo’s, “Shining More Light on the Solar Factor A discussion of Problems with the Royal Society Paper by Lockwood and Frohlich” which quotes an analysis by Dr N. Scafetta which draws on work by Dr. Richard Willson of Columbia University, an expert in satellite solar data.
I have constructed this graphic above which juxtaposes competing interpretations of satellite solar data. There are discontinuities in satellite data series. Lockwood uses the PMOD interpretation which purports to show a slight downward trend. The ACRIM version shows an increasing trend in TSI.
