Ocean rises would hit homes but help anglers
Fishing in the Pilbara could become even better in the next 200 years if the latest sea level modelling by a team of US climate scientists is anything to go by.
Climate Centrals’ global mapping project shows a 4C rise in global temperatures would see the ocean swallow almost all of Onslow and Port Hedland, as well as parts of Exmouth, Roebourne and Wickham.
Small sections of Pegs Creek, Bulgarra and Millars Well in Karratha would be inundated as well.
A saltwater channel would be cut through the middle of the Burrup Peninsula and Cape Lambert, cutting off Dampier and Point Samson.
While all this would undoubtedly be good news for anglers, given the extra structure created for fish to hide, it would have a severe impact on industry and residences in every coastal town.
The report is based on sea level rises that could happen within 200 to 2000 years if nothing is done to curb the current level of greenhouse gas emissions.
About 10,000 people would lose their homes, with many more affected by the loss of industry and major roads.
If emission levels are cut and global temperatures increase by only 2C, the data show a sea level rise of about 4.7m.
Onslow and Port Hedland would still be inundated and all other Pilbara coastal communities would see at least a minor effect.
If this lesser sea level rise were to occur, about 1500 people, mostly in Port Hedland, would stand to lose their homes.
