Cosmic pattern to UK tree growthby Matt Walker at the BBC
The growth of British trees appears to follow a cosmic pattern, with trees growing faster when high levels of cosmic radiation arrive from space.[…]
As yet, they cannot explain the pattern, but variation in cosmic rays impacted tree growth more than changes in temperature or precipitation.
rays impacted tree growth, the Beeb goes further than the data actually warrant. Cosmic rays are positively correlated with tree growth, but their effect may be negligible. It may be something else, also correlated with the rays, that has been affecting growth rates.)
