The climate continuously changes and always will.
Not all areas are experiencing coastline loss. Along the southwest coast of the UK the waters are receding creating more land on which to build. Homes that were “waterfront” are so far back another road and neighborhood could be built in front of them.
The energy companies must have people posting replies to every single article on climate change. Reassuring us that nothing is happening, that our planet is not in dire trouble and that our agricultural crops aren’t at risk of failure due to storms, heatwaves, drought and pest encroachment brought on by the rapidly changing climate. And to be clear, I’m talking about the climate change caused by man-made greenhouse gases. The thing we all need to do something about quickly.

You are right that the Earth’s climate has changed through out hundreds of million of years. Some of the changes originate from astronomical cycles; cycles that can have a frequency of thousands of years or more. Other changes have been more immediate and catastrophic, believed to have originated by meteorites hitting the Earth, which caused mass extinctions (~ 400 million and ~ 70 million years ago) or perhaps periods of extended vulcanism – most likely causing a severe cooling effect. The temperature / humidity of the lower atmosphere is regulated mostly by humidity (water) content and gases such as C02, methane, and others which have have changed as a function of what type of living organisms inhabit the earth and natural chemical thermodynamic processes. The atmospheric system is extremely complex. When modern humans appeared hundreds of thousands of years ago, we started modifying the surface of the planet like no other, especially by first burning wood, then massively burning wood and coal, then some 150 years ago by the widespread use of fossil fuels. Burning of wood, coal, and fossil fuels produces CO2, N2O and those gases happen to be strong absorbers of infrared radiation (heat) so the increase in concentrations of these and other “anthropogenic” gases has been correlated with temperature increases in the Earth’s surface which in turn affects how the oceans currents flow and distribute heat and the temperature of the lower atmosphere, etc. No mystery – “if I add more salt to water it becomes saltier”. For my own education, I quickly checked UK+ sea level rise, I read that there is a high degree of concern about sea level rise/coastal flooding in the UK. See
