Data analyses and model simulations have recently indicated that as the planet is warming, the chance for extreme events increases. Karl et al..  examined precipitation records over the 20th century and showed that the high-frequency (up to interannual) variability has increased. Subsequently Tsonis  showed that the low-frequency variability has also increased. These variability trends indicate that the frequency of extremes (more drought events and more heavy precipitation events) has increased whereas the mean has remained approximately the same. Such a tendency is observed with other variables and is consistent with model projections of a warmer planet.
