Weather: Cold Spell Set To Follow Spring Sun

Extreme UK Weather Prompts Warning

Updated: 8:59am UK, Monday 04 March 2013

The extremes of weather that Britain has experienced over the past year highlight the urgent need to plan for a changing climate, the head of the Environment Agency has warned.

Analysis by the Government agency reveals that one in every five days last year saw flooding in England and Wales, while one in four days were spent in drought.

There was flooding on 78 days of the year, and for 95 days there was official drought declared for some areas, figures from the EA show.

Rivers such as the Tyne, Ouse and Tone went from record low levels to experiencing their highest flows since records began, in the space of four months, the agency said.

Recent Met Office analysis suggests the UK could experience a 1976-style drought every 10 years.

The EA said that with the population of London and the South East set to grow by 23% by 2035, action should be taken now.

Modelling suggests some river flows could be cut by up to 80% during the summer in the next 40 years as the climate changes, putting more pressure on businesses that rely on taking water from rivers for irrigation.

The EA has called for an increase in small-scale water storage reservoirs, which can take advantage of wet times and help farmers, commercial turf growers, golf clubs, sports stadiums and racecourses cope with dry periods.

There are currently around 1,700 such water storage reservoirs in England and Wales, supplying around 30% of irrigation needs, but they will need to increase as the UK faces more extreme weather as the climate changes, the agency said.

EA chairman Lord Smith said: "The extremes of weather that we saw last year highlight the urgent need to plan for a changing climate.

"In 2012 we saw environmental damage caused by rivers with significantly reduced flows, hosepipe bans affecting millions and farmers and businesses left unable to take water from rivers.

"But we also saw the wettest year on record in England, with around 8,000 homes flooded.

"Interestingly 2007 - which also saw some of the most severe flooding in recent memory - also started the year with hosepipe bans.

"More of this extreme weather will exacerbate many of problems that we already deal with including flooding and water scarcity, so taking action today to prepare and adapt homes, businesses, agricultural practices and infrastructure is vital."
