After studying the Earth's climate changes and the 10-year cycle of solar flares for 30 years, researchers have discovered that increased solar flare activity often precedes changes in ocean currents that influence global climate. This suggests that climatologists could enhance their climate predictions using this data.
Which of the following, if true, most seriously undermines the argument above?
