Jakarta –
According to the latest research, up to 95% of the surface according to on Earth will change by the end of this century, unless humans are willing to change by reducing carbon emission.
Quoted from Nature World News, most marine life is supported by a sea surface climate characterized by surface water temperature, acidity, and concentration of the mineral aragonite, which many sea creatures need to make bones and shells.
However, with CO2 levels in the atmosphere rising at a rate not seen in at least three million years, there are concerns that surface temperatures according to may become less hospitable to the species that live there.
The Impact of Carbon Pollution on the Ocean
Researchers in the US have been studying the impact of carbon pollution on sea levels since the mid-eighteenth century. They also predict how emissions will affect the world by 2100.
They do it by simulating conditions according to around the world over three time periods: the beginning of the nineteenth century (1795-1834), the end of the twentieth century (1965-2004), and the end of the twenty-first century (2005-present).
The simulation models were then put through their paces in two different emission scenarios. The first, dubbed RCP4.5, predicts a peak in greenhouse gas emissions by 2050, followed by a gradual decline over the rest of the century.
The second scenario, RCP8.5, is one in which emissions continue to increase over the next 80 years. The researchers found that under the RCP4.5 scenario, 36% of the existing sea level conditions throughout the twentieth century are expected to disappear by 2100.
This percentage rises to 95% under the high emission scenario. The researchers also found that, while sea level climate showed minimal change during the twentieth century, up to 82% of sea level may experience an unprecedented climate by the year 2100.
Uninhabitable
According to which are hotter, more acidic, and have fewer minerals, are uninhabitable for marine life to thrive. According to lead study author Katie Lotterhos of the University of Northeastern’s Center for Marine Science, changes in ocean composition as a result of carbon pollution are likely to affect all sea surface species.
While surface species have been able to migrate to escape abnormally warm or acidic regions of the oceans in the past, this study suggests that near-uniform warming and acidification created environmental conditions that limited their migration options.
“Many marine animals have changed their ranges as a result of warmer waters. In the coming decades, communities of species found in one area will continue to move and change rapidly,” Lotterhos said.
He stated that the government should monitor changes in the behavior of sea surface species in the future. However, in the end, the emissions that cause global warming and acidification must stop.
“In 2100, a unique and disappearing climate on the surface according to would happen all over the planet without (emissions) mitigation,” Lotterhos said.
