United Nations: Severe weather conditions and greater hurricane damage by 2050

UNITED STATES, WASHINGTON (OBSERVATORY) — The sea ​​level has risen two and a half times faster than in the 20th century and is expected to increase as ice sheets recede, according to a UN climate report released Wednesday.

Regardless of the scenario, the sea level will continue to rise after 2100. If the earth’s temperature increases by 2 degrees Celsius, it may become stable at about one meter in 2300, versus several meters if greenhouse gas emissions continue along these lines. Reported.

Many major cities will be exposed to severe weather every year by 2050

Major coastal cities and smaller “many” islands are also expected to be exposed to severe weather every year by 2050, even if they reduce global greenhouse gas emissions, according to the report.

Experts predict that by the middle of the century more than a billion people will live in low-lying coastal areas and are particularly vulnerable to the consequences of climate change. Some island countries are also likely to become “unsustainable”.

Hurricanes will increase in intensity and cause more damage

Experts point out that hurricanes of all kinds will increase even if the global warming is limited to two degrees Celsius, which would further damage the coast.

It is expected that the “average strength” of tropical cyclones and the proportion of hurricanes classified as Category IV and V will increase, even if this climate phenomenon is not generally more frequent.

Protecting coasts from the consequences of climate change will cost billions of dollars a year

The construction of facilities to protect coastal areas from rising water levels could reduce flood risks by 100 to 1,000 times, provided that “tens of hundreds of billions of dollars are invested annually,” the report said.

But this method, which benefits coastal cities, may not be very effective for agricultural delta areas or small atolls, scientists warn.
