T he 2016 film Before the Flood, distributed by National Geographic, addressed many of the issues of the climate crisis. Visit the associated website http://beforetheflood.com. On the upper menu bar hover over ‘Explore’ and select ‘The Crisis’. Before viewing the 4-minute video ‘Climate Change — The state of the science’, read the surrounding text. Assess whether the clip you then watch is based on trustworthy scientific sources. As you listen to the video commentary try to distinguish between statements that are fact, forecast and opinion.
In the upper menu bar select ‘Take Action’ and click on the right-hand option ‘Flood Maps’. This opens a default map of central New York City. Click the ‘Play’ button on the left of the lower data bar and watch how an increase of half a degree Celsius results in a rise in sea level. The blue shading on the map indicates coastal flooding by the sea expected as temperatures rise. Manually place the temperature marker on a selected figure to see what sea level rise this causes.
