Reason

SeaLevelRise.se was created to demonstrate possible local effects in Sweden from global sea level rise, using open data from various authoritative sources, such as governmental agencies and renowned research institutes. Even if the data is publicly available, it is often in a form that can be hard to digest, and this site therefore attempts to present compilations of data from several sources in easily understood formats, like maps, videos and diagrams.

Competence

SeaLevelRise.se is a hobby project without affiliation to any government, political or environmental organization. The creator is not actively participating in the field of climate science, but has 16 years of experience as a scientist in other areas and teaching at the university, and 9 years of experience of professional IT development, building a competence in understanding, compiling, processing and presenting scientific data.

History

The creator of SeaLevelRise.se created his first maps showing effects of global sea level rise, based on open data, in 2008, but it wasn't until recently detailed open data on Swedish topograhy was released to enable the kind of local mapping presented here.

Reflection

During the project to create SeaLevelRise.se, the creator had to digest quite a bit of background information about climate change, global warming and sea level rise. During this process, the awareness of this phenomenon grew from a scientific curiosity, to a real concern, and in some respects even fear of the ongoing development. The future looks far more grim today than 10 years ago, as knowledge about and understanding of the factors affecting the process have improved.

Production

A first batch of sets was produced 2017-07-14 18:48:33 +0200 - 2017-08-08 21:37:02 +0200 (detailed production plan here), 167 sets, with in total 668 videos and 5,010 images, each video made from 1,625 frames, meaning a total of 1,090,510 images and 1,033,230,336,000 pixels rendered.

A second and improved batch of sets was produced 2017-08-11 23:33:19 +0200 - 2017-09-06 01:48:51 +0200 (detailed production plan here), 167 new sets, with in total 668 videos and 5,010 images, each video made from 1,625 frames, meaning a total of 1,090,510 images and 1,033,230,336,000 pixels rendered.

Land loss and population displacement diagrams, commune indices and more pages were added, and a new, structured, graphical and mobile friendly design implemented 2017-09-06.

A batch of additional sets was produced 2017-09-08 08:10:55 +0200 - 2017-09-12 18:00:27 +0200 (detailed production plan here), 27 new sets, with 108 videos, 810 maps and 27 diagrams, bringing the total to 194 sets, 776 videos, 5,820 maps and 194 diagrams, each video made from 1,625 frames, meaning a total of 1,267,014 images and 1,200,339,148,800 pixels rendered, and each video being 65 s long, meaning a total run time of 14 h 0 m 40 s.

Land loss and population displacement tables were added and linked for all of Sweden and all Swedish communes, and new commune indices including new sets were added 2017-09-12.

A batch of additional images was produced 2017-09-13 00:00:57 +0200 - 2017-09-13 04:53:28 +0200, 4 new images per set, so 776 new images, bringing the total to 194 sets, 776 videos, 6,596 maps and 194 diagrams, each video made from 1,625 frames, meaning a total of 1,267,790 images and 1,205,424,742,400 pixels rendered, and each video being 65 s long, meaning a total run time of 14 h 0 m 40 s.

A fourth batch of improved images was produced 2017-09-13 13:38:08 +0200 - 2017-10-14 17:52:00 +0200 (detailed production plan here), 194 sets, 776 new videos, 6,596 new maps and 194 diagrams, each video made from 1,625 frames, meaning a total of 1,267,790 images and 1,205,424,742,400 pixels rendered, and each video being 65 s long, meaning a total run time of 14 h 0 m 40 s.
