- As we deal with an onslaught of rain and wind with the potential for flooding in Quebec, a new study shows the impact of rising sea levels across the globe.
- The study was also published with an interactive map that lets you see the land projected to be below the annual flood level by 2050.
- Take a look at the map below.
A new report released by Climate Central is looking into the future of flooding as sea levels rise at an increasingly alarming rate. A new interactive map shows regions where it is common to already see flooding in Quebec.
The report is titled Flooded Future: Global vulnerability to sea-level rise worse than previously understood, and it outlines how previous estimates have fallen short in terms of properly explaining the danger of rising sea levels as it relates to climate change.
Greenhouse gases (GHGs) contribute to the warming and eventual melting of "land-based ice sheets" in Greenland and Antarctica, which are quickly becoming destabilized as humanity continues to pollute and add more GHGs to the atmosphere.
The consequences of this melting range from "near-term increases in coastal flooding that can damage infrastructure and crops to the permanent displacement of coastal communities."
This new report indicates that water elevation estimates have actually tripled, meaning that there is now even more global vulnerability to the rising of sea levels.
In addition to the report, Climate Central also released an interactive map based on their new data, to highlight regions that have land at risk of ending up underwater as early as 2050, as sea levels continue to rise.
Below is a section of the interactive map that highlights several regions along the St. Lawrence River, from Sorel northeast up to Trois-Rivières, that could face the threat of rising water levels and eventual displacement as a result.
Several other regions along the St. Lawrence in Quebec also face this danger. Take a look at the interactive map on Climate Central's website right here.
Of course, here in Canada, we are pretty lucky that there is plenty of non-coastal land available to us, and regions along affected bodies of water are small in comparison to other parts of the world.
Consider the Bahamas, for example:
Nearly every island that makes up the Bahamas is will be impacted, likely resulting in the displacement of thousands as communities are forced to find higher ground.
Climate Central decided to put this new report together after data showed that the elevation of many regions was improperly reported, meaning threat estimates were unindicative of the real potential risks to coastal communities as sea levels continue to rise.
Below you can see the comparison between the old method and the new method when looking at the threat to Bangkok, Thailand, a city notoriously prone to flooding.
This new data uses new techniques to better estimate the impact of rising tides based on elevation information, region-by-region.
