The Special Climate Change Fund was established in the year 2001. This fund was created as a part of the United Nations Framework Convention on Climate Change to support developing countries in their efforts to mitigate and adapt to climate change. Option 1, 1999, is incorrect as the fund was not established in that year. Option 2, 2000, is also incorrect as the fund was established a year later. Option 4, 2003, is also incorrect as the fund had already been established by then. Therefore, the correct answer is option 3, 2001.
