Climate change: 2003 was the hottest summer ever in Europe; in 2005 a hurricane of unequalled strength, Wilma, destroys Cancun; in 2009 record-breaking rainfall causes serious damages in El Salvador, Guatemala, Honduras and Nicaragua; in 2010 Tabasco is flooded by an extremely intense storm. Glaciers are melting and corals are dying as the sea warms up.
The Egyptian pyramids have survived over 3,000 years until today; the species living in the Galapagos have been evolving over thousands of years; Machu Picchu is an amazing reminder of the Inca civilization. These sites are among those with an outstanding universal value and must be preserved for future generations. They constitute common legacy, which is why the United Nations Educational, Scientific and Cultural Organization (UNESCO) has defined them as World Heritage sites.
Climate Change is now threatening the conservation of these sites, and satellites have flown to the rescue of World Heritage.
