In high emission scenarios, the sea surface of the world is very likely to rise between 0.5 and 1.9 meters by 2100.
Expert judgment is essential through the process of predicting the rise in the sea level. The arrow shows the flow of information from experts (green arrows) and probable projections (blue arrows).

Research warns that carbon dioxide rate of rise is ‘incompatible’ with 1.5℃ target
Credit: Unsplash/CC0 Public Domain Carbon dioxide in the atmosphere is increasing at a rate that is incompatible with keeping global warming below 1.5 degrees Celsius (34.7 degrees Fahrenheit), a Japan Meteorological Agency study warns. Concentrations of major greenhouse gases rose in 2024 at the fastest annual level in a long-term record of measurements at Hawaii’s Mauna Loa, which dates back…

Researchers seek ‘safe haven’ for scientific collaboration as geopolitical tensions rise
Credit: Pixabay/CC0 Public Domain A new article highlights the need for a ‘safe haven’ for researchers amid rising geopolitical tensions. A prime example of this is the history of IIASA, which was established as a neutral site during the Cold War. In a commentary published in the journal Nature, U.S. and Chinese researchers discuss the fraying of political relations between…

Work or play? The rise of online ‘kidfluencers’ raises complex legal and ethical questions
Credit: Pixabay/CC0 Public Domain Videos of children unboxing and playing with toys have become a hallmark of online marketing, making stars out of children as young as two years old. For example, 12-year-old influencer Ryan Kaji earns US$30 million a year on YouTube, where he leads one of the most popular children’s channels. His empire was built on unpacking toys.…

Cooling: Slowing ocean circulation could limit Arctic temperature rise
A map depicting the direction in which the AMOC transports warm water from the tropics to high latitudes. Credit: R. Currie, Woods Hole Oceanographic Institution/Science/USGCRP The Arctic is warming three to four times faster than the global average. But new research suggests that slowing major ocean currents could reduce projected Arctic warming by up to 2C by the end of…

El Niño Southern Oscillation caused temperature rise in 2023, research shows
El Niño and La Niña are warm and cold periods of the natural climate pattern across the tropical Pacific Ocean, known as El Niño Southern Oscillation, or “ENSO” for short. This pattern changes erratically every two to seven years, causing predictable changes in ocean temperatures and disrupting normal wind and rain patterns across the tropics. These changes in the seasonal…

Understanding Antarctica’s impact on sea level rise
Antarctic bedrock landforms and drainage basins and their estimated potential for global mean sea level rise (in metres). Areas considered particularly vulnerable are highlighted in blue. Source: Australian Antarctic Data Centre, 2024. DOI: 10.26179/q3fx-8p19 Will melting of the Antarctic Ice Sheet (AIS), Earth’s largest ice mass, cause global sea levels to rise by 5 metres, 2 metres or even less…
