Why do some claim there is no observed increase in extreme precipitation globally, when many peer reviewed papers show it is? ?
Westra et al., 2013
This study investigates the presence of trends in annual maximum daily precipitation time series obtained from a global dataset of 8326 high-quality land-based observing stations -- from 1900 to 2009 -- statistically significant increasing trends can be detected at the global scale, with close to two-thirds of stations showing increases -- there is a statistically significant association with globally averaged near-surface temperature.
Donat et al., 2013
Changes in extreme precipitation are found, for example, for the number of heavy precipitation days (R10mm, Figure 8a) and the contribution from very wet days (R95pTOT, Figure 8b). Globally averaged, both indices display upward trends during the past 60 years. Similar patterns of change are also found for the average intensity of daily precipitation
Frich et al., 2002
A new global dataset of derived indicators has been compiled to clarify whether frequency and/or severity of climatic extremes changed during the second half of the 20th century -- significant increases have been seen in the extreme amount derived from wet spells and number of heavy rainfall events
Höppe and Grimm, 2009
Throughout the world -- natural catastrophes have increased dramatically and are causing more and more damage -- The upward trend in numbers of natural catastrophes is mainly due to weather-related events such as windstorms and floods -- there is some justification for assuming that this trend is the result of changes in the atmosphere, most probably global warming.
Fischer and Knutti 2015
We show that at the present-day warming of 0.85 C about 18% of the moderate daily precipitation extremes over land are attributable to the observed temperature increase since pre-industrial times
Lehmann et al. 2015
We present the first analysis of record-breaking daily rainfall events using observational data. We show that over the last three decades the number of record-breaking events has significantly increased in the global mean. Globally, this increase has led to 12 % more record-breaking rainfall events over 1981-2010 compared to those expected in stationary time series.
Papalexiou and Montanari, 2019
Here we perform a global analysis of 8,730 daily precipitation records focusing on the 1964-2013 period when the global warming accelerates -- globally, over the last decade of the studied period we find 7% more extreme events than the expected number.
Zhang et al., 2013
This study provides estimates of the human contribution to the observed widespread intensification of precipitation extremes -- over the Northern Hemisphere land area for 1951-2005 -- the effect of anthropogenic forcings can be detected in extreme precipitation observations. We estimate that human influence has intensified annual maximum 1 day precipitation in sampled Northern Hemisphere locations by 3.3%.
Paik et al., 2020
During 1951-2015 -- anthropogenic greenhouse gas influence is robustly detected in the observed intensification of extreme precipitation over the global land and most of the sub-regions considered
Donat et al., 2016
Here we investigate changes in these two aspects in the world's dry and wet regions using observations and global climate models -- extreme daily precipitation averaged over both dry and wet regimes shows robust increases -- this intensification has implications for the risk of flooding as the climate warms, particularly for the world's dry regions.
There is a direct influence of global warming on changes in precipitation and heavy rains -- globally averaged over the land area with sufficient data, the percentage contribution to total annual precipitation from very wet days (upper 5%) has increased in the past 50 years.
Sam, extreme precipitation is not good for crops. Leaves underwater quickly die, heavy rain washes away soil and nutrients, and flooded fields cannot be accessed by the equipment farmers use to maintain them.

Trying to explain ‘peer reviewed paper’ to a denier is like trying to explain a jet engine to a monkey. Pointless.

Many papers show the opposite of what you say.

And yet crop yields have increased for decades. "Risk of flooding" is speculation. Global flooding has not increased.

They claim it because they are con clowns who wouldn't have a job if they didn't get picked up to shill and spread lies for climate deniers.
