Global warming is related to climate and is a global phenomenon. Even though there are regional cold snaps (weather), the average global temperature (climate) continues to increase even during different regions' winter months, the two scientists went on to explain.
It is estimated that groundwater flooding affects a few hundred thousand properties in the UK. Groundwater flooding occurs as a result of water rising up from the underlying rocks or from water flowing from abnormal springs.
Industrial discharges, urban activities, agriculture, groundwater pumpage, and disposal of waste all can affect groundwater quality. Contaminants can be human-induced, as from leaking fuel tanks or toxic chemical spills. Pesticides and fertilizers applied to lawns and crops can accumulate and migrate to the water table. Leakage from septic tanks and/or waste-disposal sites also can introduce bacteria to the water, and pesticides and fertilizers that seep into farmed soil can eventually end up in water drawn from a well.
