“The average temperature of the last 15 years has been the highest since records began”

“The ice cap has lost 40% of its thickness in 40 years”

“There could be 200 million climate refuges by 2050”

“20% of the world’s population consumes 80% of the planet resources”

Should we be surprised by those sentences? Not really, actually… I think they have been outhere outside to be also inside, there in our mind. Even if we forget them the most of the time. But thanks to movies – better let’s say like this as the word “documentary” seems to scare people – like “Home”, by Yann Arthus-Bertrand, the evidence can no longer be hidden.

An aerial camera takes us to the most breathtaking places all over the world. In a combination of beauty and horror, we see everything, from the most amazing landscape to the most destructed one, cleverly remembering us that it is up to us to chose the one we would like to live in. Meanwhile, the movie explains to us, since the beginning of life in the Earth why we have arrived to the current situation.

The movie spends some time explaining the situation for the Arctic environment, some of the more affected by the global warming and, at the same time, one of the most important one for the Earth’s future. The ice on the poles, one of the most important reserves of water in the world, is now melting, and the consequences, such as increasing of the sea level or changing of the temperature of the air, are as dangerous as unpredictable in a long term time.

But after the dark side of the movie, it comes the light. As it says, “It’s too late to be a pessimistic, I know that a single human can knock down every wall”. All of us are a single human, and humanity is just all of us. So you and me have in (y)our hands the power to change our way to walk, the path we are tracing and the print we are leaving on the Earth, Home. The decision is up to us, so go and watch the movie, and if after doing that you think you agree with its ideas, move!

The NASA Climate Time Machine

Thanks to a friend I received this website, with a name as cool as its desing: the Clime Time Machine. In this site, created by the Jet Propulsion Laboratory and the California Institute of Technology, you can track the changes in our planet through the decades, in four different aspects:

Clime Time Machine

Ice melting:this visualization shows the annual Arctic sea ice minimum from 1979 to 2007. At the end of each summer, the sea ice cover reaches its minimum extent, leaving what is called the perennial ice cover. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979. (Credit: NASA/Goddard Scientific Visualization Studio).

Sea level
: recent satellite observations have dete

cted a thinning of parts of the Greenland ice sheet at lower elevations. A partial melting of this ice sheet would cause a 1-meter (3-foot) rise. If melted completely, the Greenland ice sheet contains enough water to raise sea level by 5-7 meters (16-23 feet). This visualization shows the effect on coastal regions for each meter of sea level rise, up to 6 meters (19.7 feet). Land that would be covered in water is shaded red.

Carbone dioxide emissions: this visualization shows the amount of annual carbon dioxide emissions produced by the top 12 nations or regions from 1980-2004. Units are given in thousand metric tons of carbon dioxide emitted from fossil fuel consumption.

Average Glogal Temperature:This color-coded map shows a progression of changing global surface temperatures from 1885 to 2007. Dark blue indicates areas cooler than average. Dark red indicates areas warmer than average.

You have to drag the handle over the years to see the which is quite alarming. Of this four point, specially two are affecting polar regions: the ice melting and the rising of temperature. But, of course, everything is linked. Global warming seems to be finally on the agenda of politicians – or at least they are pretending to – but there is still much more to do. How you or your country is reacting to global warming and its side effects?
