The article, “Oceans Are Warming Even Faster Than Previously Thought” by the University of Berkley adds to the ongoing conversation about global warming and our world’s future. This research expands on the idea that scientists must look at ocean temperatures in order to fully understand this phenomenon instead of using data that is susceptible to yearly changes like El Nino. Evidently, it was estimated that ninety-three percent of excess solar energy is in the world’s oceans, thanks to greenhouse gases.
Models like the Coupled Model Intercomparison Project 5 state that the temperature of the top two thousand meters of the ocean will rise .78 degrees Celsius by the end of the century. Thermal expansion, because of this rise in temperature, will cause sea levels to rise 12 inches without the addition of melting glaciers and ice sheets. In addition, the Intergovernmental Panel on Climate Change’s (IPCC) Fifth Assessment Report accumulated that research models have shown that there has been a faster increase in the excess heat from the oceans. Moreover, around four thousand “diving robots” called Argo have been monitoring many of the oceans conditions like the temperature, pH, salinity as well as other data. Before this exciting new technology, most of the data was collected using a technology called expendable bathythermographs. However, this only collected data on water temperature only once. The updated research techniques use the atmosphere’s oxygen content to determine the speed of global warming while taking into consideration burning fossil fuels, of course. This is because warming oceans release oxygen.
Overall, I believe the path that global warming scientists are beginning to explore is crucial to understand the necessary changes we must take to take care of planet earth. From this research, it is obvious that actions even as simple as recycling initiatives are crucial to reduce greenhouse gasses and hopefully prove the CMIP5 model and other models wrong by slowing down or even preventing global warming and climate change.
