Query: Snowmass2021 Cosmic Frontier White Paper: Puzzling Excesses in Dark
  Matter Searches and How to Resolve Them   Intriguing signals with excesses over expected backgrounds have been observed
in many astrophysical and terrestrial settings, which could potentially have a
dark matter origin. Astrophysical excesses include the Galactic Center GeV
gamma-ray excess detected by the Fermi Gamma-Ray Space Telescope, the AMS
antiproton and positron excesses, and the 511 and 3.5 keV X-ray lines. Direct
detection excesses include the DAMA/LIBRA annual modulation signal, the XENON1T
excess, and low-threshold excesses in solid state detectors. We discuss avenues
to resolve these excesses, with actions the field can take over the next
several years.
