Cyclic variations in the energy emitted by the sun have been thought to affect weather patterns in the North Atlantic and the likelihood of storms and floods over Europe. These influences by the sun are insignificant, and could have been due to chance, suggests a new study of the instrumental record and new chemistry-climate model simulations led by Columbia/LDEO scientists.
