As the governor of a mid-west state quipped...a single 100 year storm we can accept ....3 of them in 12 years ??!!! something else is going on.

I'm Brits in certain areas would concur.

UK rains broke river flow record and climate change is to blame



More water flowed out of UK rivers into the ocean during one day last month than ever before.

As Storm Desmond drenched northern England on 5 December, rivers across the country discharged a third more water than the previous maximum, according to new data released by the Centre for Ecology and Hydrology (CEH).

The news comes a day after a study found that unusually high rainfall was made between 50 and 75 per cent more likely by climate change.

Three major storms – Desmond, Eva and Frank – tracked across Britain during December, creating what CEH called “extraordinary” hydrological conditions. They were largely responsible for the country’s wettest month since records began in 1910.

On Honiston Pass in Cumbria, Desmond delivered more rain in 24 hours than ever previously seen anywhere in the country – 34.1 centimetres. As a result, many large river catchments in northern Britain recorded their highest every peak flows, says Jamie Hannaford, who heads hydrology monitoring at the CEH.

Throughout December, several major rivers exceeded previous record flows. The peak records flows on the Tyne, Lune and Eden during Storm Desmond, each at around 1700 cubic metres a second, were the three highest flows ever recorded on rivers in England and Wales, and more than 30 times the rivers’ respective average flows, says the CEH. As these and other rivers breached their banks, some 16,000 properties flooded.

Man-made climate change raised risk for English floods: study
The study also calculated that human-induced carbon emissions caused a 43-per-cent increase in the risk of the once-in-a-century rainfall event.

Man-made climate change directly influenced the historic storms that battered southern England in the winter of 2013-2014, submerging parts of the country and causing more than $900 million in damages, says a new study by European scientists.
The study also calculated that human-induced carbon emissions caused a whopping 43-per-cent increase in the risk of the once-in-a-century rainfall event.
Published in the journal Nature Climate Change on Monday, the study comes on the heels of another series of destructive storms that hit England repeatedly last month, and again as recently as last week.
The study concluded the heightened risk for extreme rainfall in England was caused by an increase in the water-holding capacity of the atmosphere and an abnormal positioning of the jet stream, both of which are linked to climate change.

Waterfalls are supposed to flow forward and down, not backward and up, but apparently nobody told that to Storm Henry, which is currently battering Scotland.

A new scientific review of the winter floods of 2015/2016 confirms that the event was one of the most extreme and severe hydrological events of the last century.

The new hydrological appraisal -- 'The Winter Floods of 2015/2016 in the UK', published on the first anniversary of Storm Desmond (December 5th), brings together both river flow and meteorological data in an analysis of the events that led to extensive river flooding in northern England, Scotland, Northern Ireland and parts of Wales over a three month period.

The study, carried out by scientists from the Centre for Ecology & Hydrology in collaboration with the British Hydrological Society recognises that the Winter 2015/2016 episode ranks alongside the floods of 1947 as one of the two largest flood events of the last 100 years at least.

Storm Desmond alone caused an estimated insurance bill of more than £1.3 billion when it struck on the 5th and 6th December last year.

he review also highlights that 16,000 properties in England were flooded during the three months of 'remarkably persistent and exceptionally mild cyclonic' activity which, along with Storm Desmond, included the major storms of Abigail, Frank and Gertrude.

Lead author Terry Marsh, from the Centre for Ecology & Hydrology, said, "'At a national scale the winter floods of 2015/16 were the most extreme on record.
