The Logo

4Climate has chosen the kite as its logo. The kite has been used since centuries for scientific purposes. In the 19th century it has been the first vehicle to hoist meteorological instruments to high altitude.

During the early twentieth century, kites were used for measuring different atmospheric conditions such as temperature and humidity at a range of altitudes.

The kite can also be seen as a symbol for our children who represent our future. Children all over the world are united by the joy of playing with kites and by the amazement of the forces of nature, which drives them.
