From the new (26 November 2018) Met Office report on the challenge of climate change in the UK:
‘The projections will be factored into the UK’s flood adaptation planning and the Environment Agency’s advice to flood and coastal erosion risk management authorities.
Since 2010 government has invested a record £2.6 billion in flood defences, and we are on track to protect 300,000 more homes from flooding by 2021.
Chair of the Environment Agency, Emma Howard Boyd, said: “The UKCP18 projections are further evidence that we will see more extreme weather in the future – we need to prepare and adapt now, climate change impacts are already being felt with the record books being re-written.
“It is not too late to act. Working together – governments, business, and communities – we can mitigate the impacts of climate change and adapt to a different future.
“The Environment Agency cannot wall up the country, but will be at the forefront – protecting communities, building resilience, and responding to incidents.” ‘
There has been widespread and severe flooding in Lancashire and Cumbria due to unprecedentedly heavy rainfall in a short period from Storm Desmond. One feels for the people affected, many not for the first time.
‘The 405mm of rain that fell in Thirlmere in the 38 hours to 8am on Sunday marked a record amount of rain ever to fall in a 48-hour period while the 341.4mm recorded at Honister Pass on Saturday broke the highest rainfall record for any 24-hour period.’
‘Dame Julia Slingo, the Met Office’s chief scientist, said the “extraordinary” conditions were likely the result of climate change. Her comments were echoed by Liz Truss, the Environment Secretary, who told MPs: “Climate change is factored into all the modelling work the Environment Agency does but clearly in the light of this extreme weather we are going to have a look at that modelling and make sure it’s fit for purpose.” ‘http://www.telegraph.co.uk/news/weather/12038356/Floods-caught-ministers-by-surprise.html
Extreme weather events associated with climate change are already more common: we need to make sure the assumptions used in the modelling of the Oxford Flood Alleviation Scheme (Oxford FAS) sufficiently take into account the effects of climate change.
