The rare combination of
events led to unusually heavy Australian
rainfall, says Fasullo.
Warmer air can carry more moisture, which can
lead to more extreme
rainfall events, and warmer ocean surface temperatures are known to intensify the most powerful hurricanes.
Global warming also
leads to increases in atmospheric water vapor, which increases the likelihood of heavier
rainfall events that may cause flooding.
El Nino
events typically
lead to delayed
rainfall and decreased rice planting in Indonesia's main rice - growing regions, thus prolonging the hungry season and increasing the risk of annual rice deficits.
The International Panel of Climate Change (IPCC), the
leading group of the world's scientists says that glacier melting (retreat) and intense
rainfall events are two
leading manifestations of the warming weather.
Observational data, evidence from field experiments, and quantitative modeling are the evidence base of the negative effects of extreme weather
events on crop yield: early spring heat waves followed by normal frost
events have been shown to decimate Midwest fruit crops; heat waves during flowering, pollination, and grain filling have been shown to significantly reduce corn and wheat yields; more variable and intense spring
rainfall has delayed spring planting in some years and can be expected to increase erosion and runoff; and floods have
led to crop losses.4, 5,6,7
It's difficult to say for certain that a particular extreme
event for the monsoon is attributable to anthropogenic climate change — like the Pakistan floods of 2010 — but we do know that with a warming climate more moisture can be held in the atmosphere,
leading to heavier
rainfall when it does occur.
«The authors write that «the El Niño - Southern Oscillation (ENSO) is a naturally occurring fluctuation,» whereby «on a timescale of two to seven years, the eastern equatorial Pacific climate varies between anomalously cold (La Niña) and warm (El Niño) conditions,» and that «these swings in temperature are accompanied by changes in the structure of the subsurface ocean, variability in the strength of the equatorial easterly trade winds, shifts in the position of atmospheric convection, and global teleconnection patterns associated with these changes that
lead to variations in
rainfall and weather patterns in many parts of the world,» which end up affecting «ecosystems, agriculture, freshwater supplies, hurricanes and other severe weather
events worldwide.»»
During summer, most of northern Europe experienced above average precipitation, as did the Alpine region and the north of Italy and Slovenia, with a number of heavy
rainfall events heavily influencing the average for the season and
leading to wide - spread flooding
events.
But, as far as what we can expect from the IPCC and what the consensus science is, climate change is likely to
lead to increased occurrences and intensity of extreme weather
events like heavy
rainfall, droughts, warm spells, storm surges, heat waves and sea level rise.
Drought and heavy
rainfall events can make drinking water vulnerable to contamination and can ruin agriculture,
leading to increases in incidents of water - borne infections and diseases like cholera, as well as malnutrition and hunger when damaged farms fail to provide enough crops for the people who rely on them.
Moreover, rising global average temperatures
lead to longer pollen seasons in many places and — when combined with stronger
rainfall events, flooding, and higher humidity — create the perfect environment for mold to flourish.
