During the last four decades, the sea level pressure has been decreasing over the Amundsen–Bellingshausen Sea (ABS) region and increasing between New Zealand and Chile, which created pressure dipoles across the South Pacific. Researchers have now linked the natural phenomenon exacerbated by human activities and climate change to the mega droughts that have plagued South American countries like Chile for over 40 years. In this extra policy, we discuss the science behind their investigation and how crazy it is that seemingly independent events can actually be linked.
