UNITED STATES, WASHINGTON (OBSERVATORY) — A new UN report warns that climate change will cause unprecedented damage to the world’s oceans and lead to destruction if emissions continue unchecked.
The most recent special report from the Intergovernmental Panel on Climate Change (IPCC) found that by 2050, many major coastal cities and small island countries will face weather disasters every year, affecting millions and causing destruction.
The report also said that sharp cuts in emissions were needed to curb the changes, as the world saw a 1 degree Celsius rise in temperature.
This has made the oceans warmer and more acidic, and fish stocks have been affected, while melting glaciers and ice sheets have caused sea levels to rise, according to a UN scientific report.
Millions around the world live in low-lying coastal areas, from villages to major cities facing the high seas, tropical cyclones, severe storms and floods, caused by melting glaciers and ice.
The experts who conducted the report said that urgent measures to reduce greenhouse gas emissions leading to warming would reduce the damage to the oceans, frozen areas, population and wildlife.
There is also a need to focus on helping people and natural systems adapt to inevitable changes, such as rising sea levels, according to the latest report of the Intergovernmental Panel on Climate Change.
The new report, which examines the world’s oceans, coasts, ice caps or frozen regions, warns of dramatic increases in flood damage, melting ice sheets, glaciers and more heat waves in oceans that kill corals.
More than 100 scientists from around the world have assessed the latest information on the role of climate change in the oceans, coastal, polar and mountain systems and the human societies on which they depend.
The final draft of the report, approved by the countries meeting in Monaco, warns of damage to the fish and seafood stocks on which millions depend.
Sea level around the world has risen by about 15 centimeters during the 20th century, but is now rising more than twice as fast as 3.6 millimeters per year, accelerating with the melting of the Greenland and Antarctic ice sheets.
Sea levels could rise by about 30 centimeters to 60 centimeters by 2100, even if greenhouse gases were reduced rapidly and global warming remained well below 2 degrees Celsius, the report said. Sea levels may reach 60 cm to 100 cm if emissions continue to increase.
