Hello Robyn, thanks for the question and visiting the site. Geoengineering is not mentioned in the Bible per say. However, changes in the weather is mentioned. The Bible reveals that God is the Creator and Controller of the universe (see Genesis 1–2; Psalm 104:10-15; 147:8, 15-20; Job 37:3-18; etc.) When God finished His earthly creation He said in Gen 1:31 “God saw everything that he had made, and indeed, it was very good.”… When sin entered men’s hearts, the earth was also subjected to sins curse. We see this in Romans 8:19-23. Therefore, man thinking he knows better than God has taken what was very good and destroyed the finely tuned creation thru mans need to play “god” and try to prove to himself that he has no use for his creator… However, there is coming very soon judgment. Revelation 11:18 states, “The nations were enraged, and your wrath has come…. to destroy those who destroy the earth.”
