"April 18: Climate model simulations for the 21st century indicate a robust increase in wind shear in the tropical Atlantic due to global warming, which may inhibit hurricane development and intensification. Historically, increased wind shear has been associated with reduced hurricane activity and intensity."
So reports Gabriel Vecchi and Brian Sobel in the Geophysical Research Letters for April 18th. Potential good news, by God, complete with a helpful graphic from TerraDaily (via NOAA/GFDL) under the headline "A Change in the Wind." Still too model-based to hang your hat on, but worth reporting.
