Tiree Transition and Future working group

Tonight the Community Council agreed there is a need to set up a working group that takes a longer term view about the future of the island, in particular issues relating to the changing climate and sea levels, and the impacts that scientists are warning  we should now expect to face.

Tiree, as a particular low-lying island, is likely to be among the most deeply affected parts of Scotland. A recently publicised interactive map which shows the best estimates of sea level change over the next few decades suggests that we could experience serious loss of land mass in as little as 10 years. Transition away from fossil fuels is likely to need to be greatly accelerated, and it will be vital to our island’s future that our infrastructure is prepared for that, and that local businesses are supported.

If you are interested in taking part in this group and beginning a discussion about these issues and what we might be asking be done in preparation – please get in touch with TCC member Phyl Meyer by e-mail at phyl@tireecommunitycouncil.co.uk

    I read this in New Scientist a few years back as well.

    “WASHINGTON, D.C.—The Greenland ice sheet is melting. If you live in nearby Norway, how worried should you be about that sudden influx of water flooding your house? It turns out, not nearly as worried as you should be if you live in Chile. People tend to imagine that when an ice sheet melts, it adds water to all of the world’s ocean uniformly, like a bathtub filling up. “That isn’t even close,” Harvard University geophysicist Jerry Mitrovica told attendees yesterday at the annual meeting of AAAS (which publishes Science) in Washington, D.C. “Each ice sheet has its own pattern of sea level rise.” Mitrovica mapped what would happen to the world’s ocean if the rapidly melting Greenland ice sheet collapsed (as seen above). Right now, that ice is a huge weight pushing down Earth’s crust in and around Greenland. So when it’s gone, that land will pop up. An intact ice sheet also has a noticeable gravitational pull, which attracts water to the region. No ice means that water will rush away. Both of those effects actually add up to lower sea levels in the area right around the former ice sheet, Mitrovica said. When Greenland melts, places as far away as Norway and Scotland could actually see the sea level fall by as much as 50 meters. “But you pay the price somewhere,” Mitrovica said. In the Southern Hemisphere, you get more [sea level rise] than you bargained for.” The same counterbalancing effect holds for the West Antarctic Ice Sheet. If it were to collapse, the seas would rise the highest near Washington, D.C., and Northern California.”

      Hi Stewart – the source is an interactive tool which you can adjust the parameters to show just sea level rise, level plus average flooding, or level plus severe flooding, specify what decade, how much effort takes place to mitigate pollution impact, and a “luck” factor. This link takes you to it with Tiree shown, with the most positive options selected: https://coastal.climatecentral.org/map/13/-6.8615/56.5137/?theme=sea_level_rise&map_type=coastal_dem_comparison&elevation_model=coastal_dem&forecast_year=2030&pathway=rcp85&percentile=p05&return_level=return_level_0&slr_model=kopp_2014

      Pretty grim even before you start looking at the less optimistic settings.
