charcoal can create. In 1999, Horn Relief coordinated a peace march in the northeastern Puntland region of Somalia to put an end to the so-called "charcoal wars". As a result of Jibrell's lobbying and education efforts, the Puntland government in 2000 prohibited the exportation of charcoal. The government has also since enforced the ban, which has reportedly led to an 80% drop in exports of the product. Jibrell was awarded the Goldman Environmental Prize in 2002 for her efforts against environmental degradation and desertification. In 2008, she also won the National Geographic Society/Buffett Foundation Award for Leadership in Conservation. Following the massive tsunami of December 2004, there have also emerged allegations that after the outbreak of the Somali Civil War in the late 1980s, Somalia's long, remote shoreline was used as a dump site for the disposal of toxic waste. The huge waves that battered northern Somalia after the tsunami are believed to have stirred up tons of nuclear and toxic waste that might have been dumped illegally in the country by foreign firms. The European Green Party followed up these revelations by presenting before the press and the European Parliament in Strasbourg copies of contracts signed by two European companies — the Italian Swiss firm, Achair Partners, and an Italian waste broker, Progresso — and representatives of the then President of Somalia, the faction leader Ali Mahdi Mohamed, to accept 10 million tonnes of toxic waste in exchange for $80 million (then about £60 million). According to reports by the United Nations Environment Programme (UNEP), the waste has resulted in far higher than normal cases of respiratory infections, mouth ulcers and bleeding, abdominal haemorrhages and unusual skin infections among many inhabitants of the areas around the northeastern towns of Hobyo and Benadir on the Indian Ocean coast — diseases consistent with radiation sickness. UNEP adds that the situation along the Somali coastline poses a very serious environmental hazard not only in Somalia, but also in the eastern Africa sub-region. Climate Owing to Somalia's proximity to the equator, there is not much seasonal variation in its climate. Hot conditions prevail year-round along with periodic monsoon winds and irregular rainfall. Mean daily maximum temperatures range from , except at higher elevations along the eastern seaboard, where the effects of a cold offshore current can be felt. In Mogadishu, for instance, average afternoon highs range from in April. Some of the highest
