Developed nations are not immune to climate change’s symptoms, and United Kingdom’s recent floods exemplify this truth. Flash floods have drenched residential and commercial areas of London. Hospitals have had to be evacuated because of severe water inundation. The recent incidents of extreme storms and flash floods foreshadow our mounting environmental crisis. The threats that severe weather poses to infrastructure, businesses, and homes also demonstrate how urgent the problem has become; climate change is no longer a fringe issue.
In the united states alone, heavy precipitation events have been increasing on average since the 1900s. However, the IPCC estimates that the impact of global warming and climate shifts is expected to worsen on a global scale. In London, the response to flash floods has entailed evacuations, canceled operations (at Newham Hospital and Whipps Cross Hospital) closed tube stations, and restricted road-ways. Transport delays have disrupted traffic flows along major roads in central London.
The Response to Floods and Extreme Weather
The London Fire Brigade made a statement on Twitter announcing that they responded to something like 1,000 calls from people in need of rescue from their cars and or homes that were abruptly submerged in water from heavy rainfall.
The Environment Agency is responsible for responding to the risks associated with floods in London. It seems that the Environment Agency’s plans include working with water companies to make UK cities less vulnerable to flooding. This will require improving water drainage to fortify the gutter and drainage system’s capacity to carry heavy water.
London’s government is reportedly constructing a large scale tunnel that should be capable of storing and passing high volumes of rainwater. The tunnel will be known as the Thames Tideway and is expected to be finished in the year 2023. As Earth’s average temperatures increase, the intensity and frequency of heavy precipitation is expected to increase in certain areas. The regions with the largest increases in heavy precipitation events (for 1.5- 2 degrees Celsius of global warming compared to that of preindustrial levels) are the high latitude regions of Alaska, western Canada, eastern Canada, Greenland, Iceland, northern Europe and northern Asia, according to the Intergovernmental Panel on Climate Change’s SR15 Chapter 3 report.
