The areas of Helensburgh that could be underwater by 2040

As the Met Office releases its annual look at UK climate and weather for 2021, it has revealed how our perceptions of climate change have changed as trends show that sea levels are rising faster than ever.

Despite ‘unremarkable’ weather in 2021, it would have been one of the hottest years prior to 1990.

The underwater climate change study has been conducted by Climate Central, an independent organisation of leading scientists and journalists who research climate change and its impact on the public.

The organisation used current projections to produce a map showing which areas would be underwater by 2040.

The map gives an in-depth look at areas across the country, showing the specific effects climate change could have. You can view your area on the map here.

The worst affected areas are of course those with coastal fronts and sharing banks with rivers.

Areas of Helensburgh that could be underwater

In Helensburgh, the majority of Rhu Road Lower and East Clyde Street would be lost to flooding.

The whole area of the waterfront car park would be lost, as would the land right by the coastline.

However, Climate Central admits the calculations that have led to fears of a nightmare scenario include "some error".

It says: "These maps incorporate big datasets, which always include some error. These maps should be regarded as screening tools to identify places that may require deeper investigation of risk."

The maps have been based on "global-scale datasets for elevation, tides and coastal flood likelihoods" and "imperfect data is used".

Somewhat comfortingly, Climate Central adds: "Our approach makes it easy to map any scenario quickly and reflects threats from permanent future sea-level rise well.

"However, the accuracy of these maps drops when assessing risks from extreme flood events.

"Our maps are not based on physical storm and flood simulations and do not take into account factors such as erosion, future changes in the frequency or intensity of storms, inland flooding, or contributions from rainfall or rivers."

But it adds: "Improved elevation data indicate far greater global threats from sea level rise and coastal flooding than previously thought, and thus greater benefits from reducing their causes."

Mike Kendon, from the Met Office National Climate Information Centre said today of the 2021 annual report: “What we regard as fairly normal now, in the past that would have been pretty unusual, so our perception of what is normal is changing as our climate changes.”
