It is helpful to have an historical perspective, such as Jill Miles’ (Letters, June 4), when looking at recent events such as the Cape Paterson storm. Incidences of heavy precipitation, blocked drains and floods occur from time to time.
She also refers to the natural processes of erosion and deposition that are the foundation of changes to coastlines.
Other principles of physical geography and science that indicate climate change is influencing the atmosphere and oceans are also evident.
For example, warm water is bulkier than cold water – warming oceans are contributing to sea level rise; and in a warming atmosphere there is more evaporation, so more water vapour. More heat and water vapour lead to more volatile weather – so more severe localized storm events.
Take history into account – yes. But the changes at Inverloch have occurred on such a scale in a very short time period.
We should have been paying more attention and acting to address the reasons why sea levels are rising, and more extreme weather events are happening – the greenhouse gas emissions from human activities including burning coal, oil and gas.
