The fact that in some such areas there may also be flooding from extreme precipitation events is no cause for comfort.

Not exact matches

For instance, though about 30 percent of farmers surveyed agreed that extreme weather events will become more frequent in the future, 52 percent agreed that farmers should take additional steps to protect their land from increased precipitation.

Based on over a decade of asthma hospitalization data (115,923 cases from 2000 - 2012), researchers observed higher risk of asthma hospitalization after extreme heat or extreme precipitation events.

Daniel Swain and colleagues model how the frequency of these rapid, year - to - year transitions from extreme dry to wet conditions — which they dub «precipitation whiplash events» — may change in California's future as a consequence of man - made warming.

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.

Changes in precipitation regimes and extreme events can cause ecosystem transitions, increase transport of nutrients and pollutants to downstream ecosystems, and overwhelm the ability of natural systems to mitigate harm to people from these events.

Heat waves, extreme precipitation events and flooding or extreme droughts, are also what actually cause climate damage — for instance lower agricultural productivity (as during the extremely hot 2003 summer in Western Europe) or biodiversity decline at ecosystem levels ranging from aquatic desert systems to entire rainforest biomes.

Evidence that extreme precipitation is increasing is based primarily on analysis1, 2,3 of hourly and daily precipitation observations from the U.S. Cooperative Observer Network, and is supported by observed increases in atmospheric water vapor.4 Recent publications have projected an increase in extreme precipitation events, 1,5 with some areas getting larger increases6 and some getting decreases.7, 2

Northeast states can expect more climate change related heat waves — with significantly more days above 90 degrees F — and flooding from sea level rise and extreme precipitation events.

The IPCC reports that the risks associated with extreme weather events (heat waves, extreme precipitation, and the like) are moderately increased with the approximately 1 °C warming that we have already experienced (the recent report from the National Academies would support that conclusion) and that further warming will increase those risks.

Output from global circulation models indicates that climate variability will continue to be an important characteristic of the region in the future [52], but that climate change may increase the risk of extreme climatic events such as multi-decade droughts and extreme winter precipitation [53], [54].

The report, written by 220 experts from 62 countries, finds that climate change has already contributed to changes in extreme events — such as heat waves, high temperatures, and heavy precipitation — in many regions over the past 50 years.

It is instructive to compare these numbers with those characteristic of a set of the years during 1979 — 2012 with no or only one major regional extreme event (in terms of land surface temperature and land precipitation anomalies) in the NH midlatitudes, from late April / early May to late September / early October, as reported yearly since 1993 in the World Meteorological Organization statements on the status of the global climate (see also ref.

In contrast, while many African countries experience a similar trend in rapid urban coastal growth, the level of economic development is generally lower and consequently the capacity to adapt is smaller Coastal industries, their supporting infrastructure including transport (ports, roads, rail and airports), power and water supply, storm water and sewerage are highly sensitive to a range of extreme weather and climate events including temporary and permanent flooding arising from extreme precipitation, high winds, storm surges and sea level rise.

If the negative effects of climate change, the rising air temperatures, the changing precipitation, the prevalence of extreme weather events, and the rising sea levels, become too disruptive or costly, we have the option to deploy certain climate altering technologies to remove greenhouse gases directly from the air or reflect sunlight back out of the atmosphere before it warms the earth.

Indicators based on daily precipitation data show more mixed patterns of change but significant increases have been seen in the extreme amount derived from wet spells and number of heavy rainfall events.

Whilst the extent of climate change is often expressed in a single figure — global temperature — the effects of climate change (such as temperature, precipitation and the frequency of extreme weather events) will vary greatly from place to place.
