Particle physicists look for unique quantum numbers to describe the particles they study:
electric charge; spin; lepton number; etc. Since there are only two non-arbitrary speeds
in the universe, zero and light speed c, particle physicists label their quarry by the
rest mass m0 (measured at zero relative speed) if the particle can be brought to rest.
If the particle can't be brought to rest, then it is massless and travels always at the speed
of light.
If you want to define "mass" as "resistance to acceleration" or "gravitational charge,"
then mass definitely increases with relative speed. A particle physicist would say
that the energy of the particle increases with speed.
E = m(v) c2 = m0 γ(v) c2,
where γ(v) = (1 - v2/c2)-1/2

This is mentioned briefly in http://www.cfidc.org/opp/jordan.html
but the details are maddeningly absent.
"The final hypothesis for solar forcing of global warming involves the
modulation of intergalactic cosmic rays by the solar-cycle-dependent
interplanetary magnetic field. Reductions in this magnetic field during the
minimum of solar activity increases comic-ray penetration into the Earth's
atmosphere. It was postulated that during this period of increased cosmic
ray penetration, cloud formation would be enhanced through the cloud chamber
effect well known to physicists in the high-energy laboratory. An early,
surprisingly high positive correlation of increased cloud formation with
enhanced cosmic-ray flux stimulated interest in this possibility, but
further work with a more extensive database has negated it. This was not
surprising, given a large number of other problems with this hypothesis too
technical to review here."
