Climate changes: maybe it’s not entirely our fault

Copenhagen is more active than ever. A European city that apparently also “never sleeps”, Copenhagen is now hosting the Climate Conference. During these days, the city is known by Hopenhagen. Politics and associations, from all over the world, are gathered here to discuss and negotiate issues related to industrialized nations and emerging nations. Topics like thinking green, deforestation, CO₂ emissions to the atmosphere, etc are in agenda. And everybody is heard, or almost everybody. This conference has no space for the voice of Henrik Svensmark and it’s co-workers from the University of Copenhagen.

It’s amazing how the history repeats itself. All the new ideas that are out of the box and radical are never accepted. Like Galileo and Van Gogh, apparently one still has to die before its genius is recognized.

Henrik Svensmark and co-workers defend that the climate changes are not an exclusively consequence of man’s work. This story begins in 1991, when Henrik Svensmark’s group, leaded at that time by Eigil Friis-Christensen, proved that the warming of the planet was not mainly due to the release of CO₂ to the atmosphere but that there was a nearly perfect correlation between solar magnetic activity and temperature: when the magnetic activity in the sun was larger, the temperature on earth was higher. Later, in 2005, Henrik Svensmark and co-workers found experimental evidence that sun and the galaxy are determining climate on earth. By studding the clouds, they have managed to establish a correlation between the warming of earth and sun. Briefly, the idea is that cosmic rays are responsible for forming clouds and the sun with its magnetic field controls this cosmic radiation. The solar magnetic field has more than doubled in the last 100 years and as a result fewer cosmic rays (formed by stars dying in supernova-explosion) have sprayed the earth and therefore fewer clouds were formed (they keep the earth cooler). Unfortunately, no scientific journal wanted to publish this. Maybe they are wrong. But the data is shown to be very accurate. Maybe the climate change is not just our fault. Still we have the obligation to preserve and cherish our planet.
