Climate change is a difficult one !
yes the weather patterns are changing - hotter temperatures and also rain in ‘bigger dollops’ being the most obvious changes.
Perhaps the most important problem that drops out of that is the impact on our historic flood defence policy. As flood heights get higher (more rain in shorter time periods and more concrete on the ground so more runoff) so 1 in 100 year floods actually become more regular events. Maybe even once every 10 or even 5 years.
Because we have too many people in this country, during recent times the government has allowed lots of house building on flood plains. These homes are now at serious risk and soon become un-insurable. The EA has argued against this policy -but has been ignored. The govt may have to start a subsidised insurance scheme….
We are now going to have to spend many billions protecting these homes by raising flood defences AND altering the way our rivers are managed. I foresee a return to the bad old days when river authorities cut down every tree along rivers and did much too much dredging in an effort to help ‘get rid’ of water in winter. Within the EA the pendulum swung away from flood defence in the 90’s and early millennium years (conservation being the benefactor) but now flood defence is going to have to call the shots.
All of the above is bad news for fish and fishing !
The other side of that coin is the fact that we have a water abstraction licence system that isn’t fit for purpose and furthermore not enough water storage capacity (at least in the Southern half of the country). So even when it isn’t raining, too much water is abstracted from the rivers and then we don’t save it when we have too much…..Add in a rising population AND rising per capita water consumption and you have a perfect storm.
I sat on the EA Thames region Recreation and Fisheries advisory committee for over a decade and we (the fishery reps) consistently argued in support of the proposed new Abingdon reservoir. Thames Water managed to stop the plan a few years back - so there is no prospect of a new reservoir in the SE this side of 2030.
All we need is two dry years in a row and the SE will run out of water……
Thames Water is well aware of that risk - a proposal to build a de-salination plant (as back up) in London was tabled 15 years ago. Needless to say it didn’t get built.
I told you I was a Pessimist !
