The increase in rainfall intensity (shift in distribution of rain from more light events to fewer heavy events) as a consequence of global warming is a robust feature of GCMs.

So: The study finds a fingerprint of anthropogenic influences on large scale increase in precipitation extremes, with remaining uncertainties — namely that there is still a possibility that the widespread increase in heavy precipitation could be due to an unusual event of natural variability.The intensification of extreme rainfall is expected with warming, and there is a clear physical mechanism for it, but it is never possible to completely separate a signal of external forcing from climate variability — the separation will always be statistical in nature.

Pielke critiques the state of flood research, but sidesteps the strong evidence showing that extreme rainfall events have increased due to human - caused climate change.

Extreme rainfall events and flooding have increased during the last century, and these trends are expected to continue, causing erosion, declining water quality, and negative impacts on transportation, agriculture, human health, and infrastructure.

Precipitation occurs about once every seven days in the western part of the region and once every three days in the southeastern part.77 The 10 rainiest days can contribute as much as 40 % of total precipitation in a given year.77 Generally, annual precipitation increased during the past century (by up to 20 % in some locations), with much of the increase driven by intensification of the heaviest rainfalls.77, 78,79 This tendency towards more intense precipitation events is projected to continue in the future.80

In particular, in the European Mediterranean region, increases in the frequency of extreme climate events during specific crop development stages (e.g., heat stress during flowering period, rainy days during sowing time), together with higher rainfall intensity and longer dry spells, are likely to reduce the yield of summer crops (e.g., sunflower).

In addition to direct crop damage from increasingly intense precipitation events, wet springs can delay planting for grain and vegetables in New York, for example, and subsequently delay harvest dates and reduce yields.67 This is an issue for agriculture nationally, 65 but is particularly acute for the Northeast, where heavy rainfall events have increased more than in any other region of the country (Ch.
