The project has to do with climate change and how it is affecting sea levels around the world.  Saturday, students will be using blue chalk to draw a line indicating how the sea levels could rise by the end of the century.

"The kids go to the sidewalks and the streets where we've mapped the one meter contour line above present day high tide.  This the level, the sea level is thought that it's going to reach by the end of the century,” said Chad Fletcher of the Blueline Project.

Several organizations are sponsoring the Blueline Project, including the Sierra Club and the Blue Planet foundation. 

Fletcher says the importance of the Blueline Project is to let current and future generations know about what he calls a dangerous increase in carbon dioxide emissions. 

Anything more than 350 parts per million, he says, is a threat.

"One of the difficulties in managing global warming and sea level rise in particular is that it's a very slow process.  We can continue to ignore it generation after generation, unless we take action like the blue line project to call attention to this problem,” said Fletcher.

The Blueline Project is similar to public awareness campaigns being waged elsewhere.

"It's being done around the world.  The Blueline Project is unique to Hawaii.  But recognition of 350 parts per million as a safe level to attempt to return to for greenhouse gas emissions is being done around the world today,” said Fletcher.

Graphic maps display disturbing images speculating how high the sea level may go, according to the global warming scenario.  Fletcher says the project has special significance for the islands.

"It does.  Hawaii is especially vulnerable to the impacts from global warming.  Not just sea level rise, but we've also seen a decrease, a long term decrease in the amount of rainfall in the islands, and we've seen an increase in the average temperature in the islands."
