Meteorologists discuss how the El Nino cycle, influenced by global warming, has contributed to a spike in Earth's temperatures over the past three years. A new study reveals that changes in the El Nino and La Nina cycles are linked to an increase in Earth's energy imbalance, leading to warmer temperatures. The US NOAA has updated its criteria for labeling these weather patterns due to rapid climate changes. The study indicates that a long La Nina cycle has contributed to recent temperature increases, and an El Nino is expected to develop soon, potentially leading to record global temperatures.
