ship. Because the humidity-rainfall relationship is a key component in theories for other tropical atmospheric phenomena, such as the Madden Julian Oscillation, the authors note that their model could also help improve scientists' understanding of those features.

3. Radioactive tracers illuminate ancient solar cycles

Past solar activity can be inferred using records of cosmogenic isotopes, including beryllium-10 and carbon-14, which are produced in cosmic ray showers at rates that vary with solar activity. To study solar variability and possible links with Earth's climate during the Holocene (the past approximately 11,700 years), Knudsen et al. analyze both beryllium-10 and carbon-14 data records. The authors find that both records showed that the periodic nature of the solar activity was especially pronounced 6000-4500 years ago and 3000-2000 years ago, but less pronounced during other times. The dominant periodic variations had cycles about 88, 150, 220, and 400 years long. Because beryllium-10 and carbon-14 have different geochemical properties, the fact that both records show the same periodic behavior indicates that they do reflect the behavior of the Sun, the authors suggest. They also find some indication that the Sun influenced Earth's climate when the 220- and 400-year solar cycles were particularly prominent.
