Global average sea level rose by about 0.3 inches (0.76 centimeters) from 2022 to 2023 — nearly four times the increase of the previous year — NASA said Thursday, 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, with the initial satellite launching in 1992 and the latest in 2020. Overall, sea levels have risen by around four […]
While small island states are the most vulnerable to rising sea levels, the impact is much wider, warned the President of the UN General Assembly on Thursday. Addressing a special summit meeting, Dennis Francis – a veteran diplomat from Trinidad and Tobago – said he was determined to make sure the issue gets the attention it deserves during his presidency. With the climate crisis unfolding rapidly, the need for more inclusive and innovative approaches to […]
by Marlowe HOOD Agence France-Presse Ice loss from Greenland’s massive ice sheet will cause sea levels to rise more during the 21st century than they have during any 100-year period in the last 12,000 years, even if global warming is held in check, scientists said Wednesday. The study — based on ice core data and models and published in the journal Nature — is the first to painstakingly reconstruct Greenland’s ice loss record over the […]
by Marlowe HOOD PARIS, France (AFP) — The Greenland and Antarctic ice sheets, which hold enough frozen water to lift oceans 65 metres, are tracking the UN’s worst-case scenarios for sea level rise, researchers said Monday, highlighting flaws in current climate change models. Mass loss from 2007 to 2017 due to melt-water and crumbling ice aligned almost perfectly with the Intergovernmental Panel for Climate Change’s (IPCC) most extreme forecasts, which see the two ice sheets […]
by Marlowe HOOD PARIS, France (AFP) — Greenland and Antarctica are shedding six times more ice than during the 1990s, driving sea-level rise that could see annual flooding by 2100 in regions home today to some 400 million people, scientists have warned. The kilometers-thick ice sheets atop landmasses at the planet’s extremities sloughed off 6.4 trillion tonnes of mass from 1992 through 2017, adding nearly two centimeters (an inch) to the global watermark, according to […]
by Marlowe HOOD PARIS, France (AFP) — Climate change and sea-level rise are currently on track to wipe out half the world’s sandy beaches by 2100, researchers warned Monday. Even if humanity sharply reduces the fossil fuel pollution that drives global warming, more than a third of the planet’s sandy shorelines could disappear by then, crippling coastal tourism in countries large and small, they reported in the journal Nature Climate Change. “Apart from tourism, sandy […]
