The Intergovernmental Panel on Climate Change (IPCC), the apex referee for scientific evidence on the impact of global warming, released a special report on Wednesday, highlighting the dire changes occurring in oceans, glaciers, and ice deposits on land and sea, with representatives from nearly 200 nations attending the United Nations Climate Summit in the United States. According to a summary of the report that was made available to policymakers, "the ocean is projected to transition to conditions that are unprecedented over the 21st century, with increased temperatures, further ocean acidification, marine heat waves, and more frequent extreme El Nio and La Nina events." Based on current projections of global greenhouse gas emissions, the report summarizes the disastrous effects of warming and brings up to date the scientific literature that has been available since the IPCC's comprehensive 5th Assessment Report was released in 2015. Since 1970, it is almost certain that the ocean around the world has warmed unabated and absorbed more than 90% of the climate system's excess heat (high confidence). The rate of ocean warming has more than doubled since 1993. According to the report, marine heat waves have probably doubled in frequency and intensity since 1982.
