The United Nations released its latest report on global warming, having the contribution of more than 100 scientists gathered under the Intergovernmental Panel on Climate Change”, supported by more than 7,000 studies on the effects of climate change on the world’s oceans and ice sheets.
For many years, oceans have been an important factor contributing to the fight against pollution, by absorbing a quarter of the carbon dioxide and greenhouse gases in the atmosphere, and by capturing 90% of the Earth’s excess heat produced by humans. Nowadays, oceans are warmer, having a higher rate of acid and less oxygen, hence affecting marine ecosystems, the report shows.
At the same time, melted ice sheets from Greenland and Antarctica are increasing ocean levels and generate flooding more frequently. Moreover, in the mountain areas, people using melted water for agriculture and refilling water reservoirs are now in water distress due to the fact that glaciers are melting rapidly.
Things will not get any better even if governments will start implementing policies to significantly reduce carbon emissions and greenhouse gases. Already, some consequences are hard to avoid, such as the disappearance of coral reefs, the rising levels of oceans and constant threat to marine life.
