** Record Ocean Temperatures Linked to Increasing Greenhouse Gases and Solar Energy Absorption **
** Researchers at the University of Reading have uncovered significant factors behind the unprecedented rise in global ocean temperatures, which have reached record highs since March 2023. According to a study published in Environmental Research Letters, the ocean warming rate has more than quadrupled over the past 40 years, attributed primarily to a growing energy imbalance on Earth, with approximately 44% of this extra heat occurring during recent El Niño years.
Christopher Merchant, lead author of the study, emphasized that the persistent increase in greenhouse gas emissions, particularly carbon dioxide and methane, has contributed to this alarming trend by enhancing heat absorption. Additionally, decreased reflectivity due to changes in atmospheric aerosols has allowed the oceans to absorb more solar energy, further exacerbating the situation.
The rising ocean temperatures have resulted in extensive coral bleaching and intensified weather patterns, including stronger hurricanes. This year-long heating trend poses dire implications for marine ecosystems and the livelihoods of over a billion people dependent on healthy oceans, highlighting an urgent need for effective climate action.
