Here's the trailer for the film based on this book. I haven't seen the whole film but it looks like worth watching, though the writing in the novel doesn't necessitate any audiovisual guidance, I saw the happenings right in front of my eyes when reading The Road.
Sarasvatin hiekkaa is an ecological thriller set in around year 2020: several scientists around the world are working on unrelated phenomena. However, as it turns out, things are all worryingly connected: an ancient city sunk in the Indian Ocean just like the Atlantis tale tells us, a suddenly vanished arctic lake near Greenland, gas eruptions in the bottom of the sea, a man trying to build snow-producing wind mills to prevent the melting of the icebergs. Isomäki is a science journalist and author himslef so the facts are pretty much correct and also much more interesting than the romantic sidelines in the novel. This is a description of how it could happen - how the world would come to an end as we know it; the icebergs would melt, the sea level would rise, a mega tsunami would hit the continents destroying cities and leaving people in destitution. But this is only the end of the book, the fascinating part is the "how and why". Isomäki tells the story of global warming and climate change in popular terms making geology, chemistry, marine archeology, history and geography all sound like the most exciting things in the world. It's a wonderful mix of separate fields of culture and science - and a handful of (quite well-founded) pessimism.
