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.

As both evaporation rates and heavy rainfall events increase in a warming world, this lends itself to bigger variations in precipitation.

Snowfall varies across the region, comprising less than 10 % of total precipitation in the south, to more than half in the north, with as much as two inches of water available in the snowpack at the beginning of spring melt in the northern reaches of the river basins.81 When this amount of snowmelt is combined with heavy rainfall, the resulting flooding can be widespread and catastrophic (see «Cedar Rapids: A Tale of Vulnerability and Response»).82 Historical observations indicate declines in the frequency of high magnitude snowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely difficult.

Floods are the second deadliest of all weather - related hazards in the United States.57, 58 Elevated waterborne disease outbreaks have been reported in the weeks following heavy rainfall, 59 although other variables may affect these associations.60 Populations living in damp indoor environments experience increased prevalence of asthma and other upper respiratory tract symptoms.61

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

Projections suggest an increase in extreme weather events, such as heavy rainfall, more intense storms and heat - waves.

But an increase in heavy rainfall in some of these regions is also likely to bring with it many negative effects, such as a raised risk of flooding and the waterlogging of soils.

Scientists are increasingly drawing links between climate change and extreme weather events, either increasing the likelihood of heat waves, drought, hurricanes, heavy rainfall...

This, coupled with an increase in average rainfall as well as heavy rainfall events, has resulted in recurrent flooding and related damages to infrastructure, utility supply and the urban economy.

Global analyses show that the amount of water vapor in the atmosphere has in fact increased due to human - caused warming.8, 9,10,11 This extra moisture is available to storm systems, resulting in heavier rainfalls.

The heaviest rainfall events have become heavier and more frequent, and the amount of rain falling on the heaviest rain days has also increased.

Similarly, Australia has seen the odds of both heavy rainfalls and droughts increase, and similar patterns are being observed worldwide, coinciding with rising temperatures over the past 50 years.

As temperatures rise, basic physics dictates an increase in the amount of atmospheric moisture, which is the fuel for heavy rainfall events.

The PIK researchers found that heavy rainfall events setting ever new records had been «increasing strikingly» in the past thirty years.

In addition, the pattern of sea surface temperatures at low latitudes is extremely important for regional climate variations (shown, for example, by the increased likelihood of heavy winter rainfall in California when the eastern tropical Pacific warms in El Niño events).

This resulted in an increase (1.9 % / decade) in the frequency of heavy rainfall above 25 mm.

There is growing empirical evidence that warming temperatures cause more intense hurricanes, heavier rainfalls and flooding, increased conditions for wildfires and dangerous heat waves.

Food availability could be threatened through direct climate impacts on crops and livestock from increased flooding, drought, shifts in the timing and amount of rainfall, and high temperatures, or indirectly through increased soil erosion from more frequent heavy storms or through increased pest and disease pressure on crops and livestock caused by warmer temperatures and other changes in climatic conditions.

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.

Explains meteorologist Greg Holland of the National Center for Atmospheric Research: «I have no equivocation in saying that all heavy rainfall events, including this one, have an element of climate change in them, and the level of that contribution will increase in the future.»

According to the National Climate Assessment, average rainfall during heavy precipitation events across the Northeast, Midwest and Great Plains has increased by 30 percent since 1991.

The report says there is no change to the conclusion that heavy rainfall events have increased in the past, but there is greater confidence now that these will increase in the future.
