What this means

“If we look at our best numerical simulations of a magnetic field reversal, this is the type of pattern we see right before a reversal,” says Dr. Tarduno. “We don’t know if the current [anomaly] will lead to a full reversal.” If the anomaly continues to grow, the patch in the outer core under Africa could be the trigger to a full pole reversal.
