"Accurate predictions of Earth’s warming require computers that are too expensive for one country or institution."
“It’s not like this is string theory,” said Timothy Palmer, professor of climate physics at the University of Oxford. “We know the equations.” But we don’t know how to solve them. The many factors that affect the climate interact with one another and give rise to interconnected feedback cycles. The mathematics is so complex, the only way scientists know to handle it is by feeding the problem into computers, which then approximately solve the equations.
