By 2050, these numbers could increase to a quarter of UK homes flooding. The building of 1.5 million more homes has been proposed for the coming years, but more than 10% of these are being built in areas prone to flooding. And in less than 25 years, by the time most us will be in our middle age, half of the rail network - a public trans- port system that could reduce our emissions overall - will be con- sumed by floodwater. Development can increase the economy, yes, but it will reduce the amount of rain being absorbed into the earth and will only drive flooding further.
Moreover, many famers in Somerset are suffering the blows of heavy rainfall, with their crops - and our homegrown food supply - being rotted by the floodwater. The agricultural sector lost &1 billion in crops alone in previous years of flooding.
So what's really happening? How does global warming give us so much sun, and so much rain too?
For every 1 degree Celsius our temperature rises, our atmosphere holds 7% more moisture, creating heavier rainfall. We currently expe- rience an average of 7 days a year where rainfall is more than 80mm a day (labelled a heavy rainfall 'event'). According to the UN, if tem- peratures rise more than 2 degrees Celsius, this will increase to 9 days.
Going forward without action, we can expect to see these trends worsen. Our Summers will be unbearably hot and dry, and our win- ters will be overwhelmed with water. By 2050, we will need almost 5 billion litres of water a day, far more than we currently have avail- able. That's an extra 2 million green bins full of water every day, as well as what we're already consuming! We need to find a way to bal - ance our water waste with our increasingly common draughts 17 and shortages.
