Incomplete records and only since 1970? Hmmm
Netweather covered it relatively well bar this deplorable bit (my emphasis);
Will it happen again?
What used to be once in 100 year or even 200 year flooding events appear to become increasingly and worryingly common, as this current event in Cumbria illustrates, 6 years since the last record breaking rainfall event in a similar area. Whether this is a direct cause of global warming, natural or man-made, is open for debate but not for discussion in this blog. But it does seem flooding is becoming a more frequent visitor to our country and nowhere seems immune, as the winter floods along the Thames a few years ago showed.
Note the ‘I’m not saying it’s climate change but…’ dirty trick followed by ‘it’s open for debate but not here’. Very tawdry. The use of the 100/200 year flood shows the author is either a complete bonehead (unlikely) confusing the statistical nature* of flooding events (and how they often cluster) or is being deliberately deceptive.
USGS research has shown no linkage between flooding (either increases or decreases) and the increase in greenhouse gases. Essentially, from USGS long-term streamgage data for sites across the country with no regulation or other changes to the watershed that could influence the streamflow, the data shows no systematic increases in flooding through time.
A much bigger impact on flooding, though, is land use change. Without proper mitigation, urbanization of watersheds increases flooding. Moreover, encroachment into the floodplain by homes and businesses leads to greater economic losses and potential loss of life, with more encroachment leading to greater losses.

There are a number of reports floating around that Storm Desmond has brought a 24-hour rainfall record, for instance;
The Government is expected to confirm a UK record in rainfall over 24 hours following the storm that submerged parts north of the country in floods this weekend.
Following an emergency Government meeting, Environment Secretary Elizabeth Truss said that figures from a rain gauge in Honister, Cumbria, suggest a record amount of rain fell in the 24 hours between Friday and Saturday evenings. It measured 341mm, which is more than a month’s worth of rainfall in just one day and more than the UK has ever experienced in such a short amount of time.
This is a very short post, as I am working on a more detailed summary of the Cumbrian floods, and will be out for most of the day.
But there is one issue…
