In the book Global Warming: The Divine Warning of Doomsday, Maulana Wahiduddin Khan explains that the United Nations’ panel of 25,000 scientists from 130 countries submitted a detailed report on global warming, titled 'Warning Signs'. The more appropriate title would have been, 'Warning Signs of Doomsday' as both Quranic revelation and science now confirm that the end of history, Qiyamah, has come very close. God had made this world for a limited period of time for a test. Now, this time is reaching its end. Now the time has finally come for man to awaken, to take lessons from the signs in nature and in history, and plan his life in a way that avails him in his post-death period before Doomsday.
