In November 2005, for example, Yuri Izrael, head of the Moscow- based Institute of Global Climate and Ecology Studies, wrote to Russian president Vladimir Putin to make the case for immediately burning massive amounts of sulfur in the stratosphere to lower the earth’s temperature “a degree or two”—a correction greater than the total warming since pre- industrial times.
Kwa Novemba 2005 kwa mfano, Yuri Izrael, mwongozi wa taasisi ya kusoma Hali ya Hewa na Taasisi, aliandika kwa Rais wa Urusi Vladimir Putin kutengeneza kesi ya kuchoma makemikali(sulfur) kwa hewa kurudisha chini joto ya dunia “digrii moja ama mbili”-- rekebisho kubwa tangu kabla ya enzi cha kiwanda.
