Revealed: How floods could hit 8,500 buildings in Dublin by 2100 if climate crisis is not averted

Homes, museums and power stations will be among the thousands of buildings at risk of flooding in Dublin by 2100 if climate change continues unabated, according to a new data visualization.

The 3D visualization of central Dublin shows that if no further action is taken to mitigate the risks of global warming, over 8,500 buildings will be flooded to an average depth of 1.7 meters by the end of the century.

Buildings and areas likely to be damaged by coastal flooding also include hotels and Dublin’s financial district, according to analysis by Cervest, a technology company that assesses the potential climate risk to the assets of businesses, governments and NGOs, such as factories and offices.

The data visualization was released on Thursday to mark the start of the Dublin climate summit.

Cervest said his visualization shows the devastating consequences for cityscapes and infrastructure if nothing is done about global warming, and warned that the physical damage will have social and economic repercussions.

In addition, the analysis only considers the risk of coastal flooding. When other climate risks are factored in – such as extreme heat and wind stress – increasing areas of Dublin will be affected, according to Cervest’s data visualization team.

If mitigation policies are soon applied — like implementing national emissions reduction commitments and deforestation pledges — that scenario could change, the visualization team said.

However, they warned that some damage was now inevitable.

“Even if we reach net zero tomorrow, the physical risk from past actions is already embedded in our system,” the team said in a statement alongside the visualization.

Globally, more than £2 trillion worth of tangible assets are already at risk from climate change, the company said, and economic losses linked to global warming are expected to rise to £18.7 trillion by 2050.

Iggy Bassi, Cervest’s founder and CEO, said the company’s insights could be used to pinpoint vulnerabilities and make informed decisions.

“You don’t have to be a climate scientist to understand this striking picture,” he said. “My city will look like this…if we don’t do anything.”

Earlier this week, the World Meteorological Organization issued a new update warning that there is now a 50/50 chance that global temperatures will temporarily reach 1.5 degrees Celsius above pre-industrial levels over the next five years.

The world has already warmed by 1.1°C since pre-industrial temperatures, leaving 1.5°C just 0.4°C away.

Even a temporary surpass of 1.5°C would be a significant moment, as the 2015 Paris Agreement aimed to keep average temperatures no more than 1.5°C above pre-industrial levels to mitigate the worst of climate change damage impede.

Exceeding the 1.5°C threshold for a year does not mean that the Paris Agreement has been broken, as the Paris target refers to the average temperature and excludes natural variations from year to year.

Still, climate experts said the update shows how fast the world is approaching that goal, which is likely to result in even more damage to lives and livelihoods as extreme weather events like flooding become more frequent and severe.
