We live in a blue little planet which turns around a medium star in a little solar system, on the outskirts of a medium galaxy which has billions of stars, and which belongs to a universe made up with billions of billions of starts. So... do you realize how tiny and fragile we are?
In April 2007 the news related to climate were about if we warm the planet more than two celsius degrees, as an average, the damage will be irreparable and maybe events will be out of control. Global temperature had increased 0.7 ºC by that moment. It was also told that we were on time to reduce our emissions but this seems not to have changed so much. There have been some steps but, have they really been enough? Some comments from the NASA.
Between the end of this century and the beggining of the following, the millions of us who already live, or have survived, we'll have to do it at the Poles where climate will be comfortable enough. James Lovelock. Scientist and inventor.
