We all know the climate is changing. But just how complicated is that process and how many factors are involved in creating this planate-wide problem? To partly answer that question, scientists have gone back nearly 90,000 years to examine Antarctic ice core samples, or, more specifically, the gas they contain. Their findings demonstrate the complex interplay between different geological players that contribute to climate changes and trends. The report implies that global warming, carbon dioxide levels, and ocean currents are not individual influencers on climate change but rather intertwined with each other. Knowing how these factors interacted many millennia ago will hopefully help scientists better understand climate change today and possibly predict future trends.
