The world climate is a mixture or chemistry, biology, geology, and nuclear physics, on an epic chaotic scale. Your average meteorologist can barely predict the weather into next week. Over geologic epochs, world weather patterns do change, sometimes for the better, but mostly for the worse. The point is, 10,000 years from now, scientists have no idea of whether where you’re stand right now will either be a hot desert, or under a mile thick layer of ice.
Trying to steer an ocean liner with a hand paddle and not being able to determine which direction you are going or which direction you came. Other then that, our science is not very well suited for the task.
