Britain's mapmakers are on the front lines of climate change, using their expertise to track and visualize the impacts of a warming planet. This is a crucial task, as it provides a tangible way to understand and address the challenges posed by climate change. Tom Gray, a utilities and transport expert at Britain's national mapping agency, highlights the importance of traditional maps in showing the effects of climate change. He demonstrates this by presenting aerial photographs and maps that illustrate habitat changes, subsidence, wildfire risks, and flooding hotspots. These maps are not just static images but dynamic tools that are updated 30,000 times a day, ensuring that the data is current and relevant.
The mapping agency's National Geographic Database is a treasure trove of information, containing over 600 million features and monitoring almost anything you can think of. This level of detail is essential for emergency services and other organizations to react effectively to climate emergencies. For instance, when coastal erosion occurs, drone pilots like Helen Jones are dispatched to collect footage and update the maps. This process is meticulous, with each block of land taking several hours to map, ensuring that even the smallest details, like access points to housing estates, are captured.
The impact of climate change is evident in the work of these mapmakers. Drought conditions, like those experienced in England and Wales this year, are now a regular occurrence, affecting not only the environment but also the work of surveyors like Jones. She notes that the lack of rain has been beneficial for drone footage but challenging for other aspects of her work. This firsthand account underscores the reality of climate change and the need for urgent action.
The role of Britain's mapmakers extends beyond data collection and mapping. It involves educating the public and authorities about the importance of accurate, up-to-date maps in preparing for and responding to climate emergencies. By doing so, they are not just tracking climate change but also helping to mitigate its impacts and build a more resilient future.
