THE Met Office have warned us to expect record breaking bad weather in the future.
Increasingly extreme weather is one of the most damaging and costly impacts from climate change, they warn.
A new set of projections from the Met Office reveal that extremes of rainfall and high temperatures are expected to exceed the extreme conditions that we have already experienced in the UK, breaking records and placing increasing challenges on health, infrastructure and services.
The latest addition to the set of UK Climate Projections (known as UKCP) will be published by the Met Office later today (Thursday).
A major focus for the UKCP projections is to help users – from Government, organisations, engineers, professionals and individuals – to understand more about how climate change is likely to impact the UK.
Professor Jason Lowe OBE is head of the UKCP programme for the Met Office.
He said: “Some of the most severe consequences of climate change will come from an increasing frequency and severity of extreme weather events.
"We know that on average the UK is projected to become hotter and drier in summer, and warmer and wetter in winter – this tells us a lot, but for those assessing climate change risk it’s important to better understand how extreme weather events are likely to change too”.
The updated projections look at extreme weather events for maximum temperature in summer; and maximum total rainfall over one-day and five-day periods.
Users can examine local areas and look at the model simulated rise for rare high temperature and high rainfall events which may happen on average only one-in-twenty, fifty or even one hundred years.

Dr Simon Brown was one of the key scientists working on the project.
He added: “If you’re designing a flood-relief scheme or building a railway, for example, you can’t assume that the climate will remain the same because we know that it is already changing.
"The things you want to know will be how much heat or rainfall will my project have to cope with and that is what our projections will do.”
To help users see the scale of change across the UK, the Met Office has published data on how maximum temperatures and one and five-day rainfall totals may rise in future.
The new results were calculated by adjusting present day extremes in line with modelled future changes in extremes out to the end of the century.
They project up to 2100 for the UK's four capital cities.
In the projection, Cardiff is expected to experience maximum temperatures of up to 37 degrees, maximum daily rainfall of up to 52mm, and five day rainfall up to 140mm.
Those rainfall figures represent a higher increase and heavier rainfall than any of the other nations in the UK.
In conclusion, Dr Lizzie Kendon said: “Future work will be to understand these changes in terms of the weather types or storms that drive these changes, to better understand the nature of the changes and help adaptation planning.
"In additional new UKCP Local projections – down to 2.2km resolution – are planned to be released in Spring 2021 providing updated information on changes in hourly rainfall extremes important for understanding future risks of flash flooding.”
