> additional warming Some perspective needed. According to [1], Earth absorbs 3.85e24 J/year from the sun. One kg of mass falling to Earth from infinity (i.e. at escape velocity, 11.2 km/s) has kinetic energy (mv^2)/2 ~ 6.27e7 J. So you would need to drop 6.14e16 kg/year on Earth to match the solar contribution. Something minor like 1000 metric tons (1e6 kg) per year would only contribute 1.63e-11 of what we get from the sun, or roughly 0.0005 seconds worth of sunlight.
