Sea level rise

United Nations Secretary-General Antonio Guterres sent out a global climate "SOS" at a Pacific islands summit on Tuesday, unveiling research that shows the region's seas rising much more swiftly than global averages.

"I am in Tonga to issue a global SOS — Save Our Seas — on rising sea levels. A worldwide catastrophe is putting this Pacific paradise in peril" he said.

A recent study has revealed that 55 percent of historical sites along the coasts of Türkiye and Greece are at a "very high" or "high" risk of submersion due to rising sea levels driven by climate change.

The annual subsidence of the ground in İzmir by 1 to 1.5 centimeters is exacerbating the rise in sea level beyond the global average, imperiling certain areas of the Aegean coastal city with the risk of submersion, an expert has said.

Global average sea level rose by about 0.76 centimeters from 2022 to 2023, nearly four times the increase of the previous year, NASA said on March 21, attributing the "significant jump" to a strong El Nino and a warming climate.

The NASA-led analysis is based on more than 30 years of satellite observations.

Sea ice levels in Antarctica have registered historic lows for three consecutive years, portending grave consequences for life on Earth as we know it.

But looking out over the southernmost continent, scientist Miguel Angel de Pablo laments that humanity seems to be oblivious to the warnings.

Even in Antarctica, one of the most remote and desolate places on Earth, scientists say they are finding shattered temperature records and an increase in the size and number of wacky weather events.

The water level in the Marmara Sea will rise by 50 centimeters by 2050, a professor warns, urging to take serious measures after 2050.

As effects of global warming, climate change, drought and excessive rainfall show themselves more and more with each passing year, experts point out that the melting of the polar ice caps affects the water levels in the oceans and the ecosystem.

Sea ice in Antarctica shrank to the smallest area on record in February for the second year in a row, continuing a decade-long decline, the European Union's climate monitoring service said March 7.

Half of the Earth's glaciers, notably smaller ones, are destined to disappear by the end of the century because of climate change, but limiting global warming could save others, according to a new study.

The findings, published in the journal Science on Jan. 5, provide the most comprehensive look so far at the future of the world's 215,000 glaciers.

Greenland's ice sheet has experienced a "massive melting event" during a heatwave that has seen temperatures more than 10 degrees above seasonal norms, according to Danish researchers.
