Greenland losing ice seven times faster than in the 1990s – Sea level rise from Greenland melt tracking highest climate projections

10 December 2019 (Utrecht University) – Greenland is losing ice seven times faster than in the 1990s and is tracking the IPCC’s high-end climate warming scenario, which would see 40 million more people exposed to coastal flooding by 2100. The findings, published in Nature today, show that Greenland has lost 3.8 trillion tonnes of ice […]

Venice is drowning. It’s a warning of what’s to come.

By Editorial Board 15 November 2019 (The Washington Post) – Venice has always been linked closely with the water that surrounds it. The city is thought to have been founded by refugees seeking protection from Germanic invaders by sheltering in the northwestern Adriatic Sea’s islands and marshes. By the 12th century, the doge would annually […]

Rising sea levels are swallowing North Carolina’s Outer Banks beaches, new report says

By Hayley Fowler 20 November 2019 CHARLOTTE, North Carolina (The Charlotte Observer) – Hurricanes aren’t the only hazard lapping at the shores of the Outer Banks, according to a report examining the threat of climate change on some of the country’s most beloved natural landscapes. Thanks to creeping sea levels and erosion rates, Cape Hatteras […]

Venice sees record third exceptional tide – Priceless artwork threatened – “It is a long-term issue. It is not the issue of one flood, we restore, and we go back to normal.”

By Colleen Barry and Luca Bruno 17 November 2019 VENICE, Italy (AP) – Venice was hit Sunday by a record third exceptional tide in the same week while other parts of Italy struggled with a series of weather woes, from rain-swollen rivers to high winds to an out-of-season avalanche. Stores and museums in Venice were […]

Amid flooding and rising sea levels, residents of one barrier island wonder if it’s time to retreat – “Is this really sustainable? The answer is pretty clearly no.”

By Frances Stead Sellers 9 November 2019 OCRACOKE, North Carolina (The Washington Post) – On any normal late-fall day, the ferries that ply the 30 miles between Swan Quarter and this barrier island might carry vacationing retirees, sports fishermen and residents enjoying mainland getaways after the busy summer tourist season. But two months ago, Hurricane […]

Italian council is flooded immediately after rejecting measures on climate change

By Gianluca Mezzofiore 15 November 2019 (CNN) – Veneto regional council, which is located on Venice’s Grand Canal, was flooded for the first time in its history on Tuesday night — just after it rejected measures to combat climate change. The historic Italian city has been brought to its knees this week by the worst […]

Just 15 years of post-Paris emissions to lock in 20 cm of sea level rise in the year 2300 – “Emissions today will inevitably cause seas to rise a long way into the future. This process cannot be reversed. It is our legacy for humankind.”

5 November 2019 (PIK) – Unless governments significantly scale up their emission reduction efforts, the 15 years’ worth of emissions released under their current Paris Agreement pledges alone would cause 20 cm of sea-level rise over the longer term, according to new research published today in the Proceedings of the National Academy of Sciences (PNAS). […]

Permanent inundation surfaces predicted by CoastalDEM and SRTM given the median K17/RCP 8.5/2100 sea-level projection. Locations include (a) the Pearl River Delta, China; (b) Bangladesh; (c) Jakarta, Indonesia; and (d) Bangkok, Thailand. Low-lying areas isolated from the ocean are removed from the inundation surface using connected components analysis. Current water bodies are derived from the SRTM Water Body Dataset.

Flooded Future: New elevation maps triple estimates of global risk from sea-level rise and coastal flooding – “By 2100, land now home to 200 million people could sit permanently below the high tide line”

29 October 2019 (Climate Central) – Sea level rise is one of the best known of climate change’s many dangers. As humanity pollutes the atmosphere with greenhouse gases, the planet warms. And as it does so, ice sheets and glaciers melt and warming sea water expands, increasing the volume of the world’s oceans. The consequences […]

If warming exceeds 2°C, Antarctica’s melting ice sheets could raise seas 20 meters in coming centuries

By Georgia Rose Grant and Timothy Naish 2 October 2019 (The Conversation) – We know that our planet has experienced warmer periods in the past, during the Pliocene geological epoch around three million years ago. Our research, published today, shows that up to one third of Antarctica’s ice sheet melted during this period, causing sea levels to rise […]

Shocked scientists find 400 km of dead and damaged mangroves in Australia’s Gulf of Carpentaria – “We are getting these compounding effects that we just didn’t expect”

By Graham Readfearn 3 October 2019 (The Guardian) – A cascade of impacts including rising sea levels, heatwaves and back-to-back tropical cyclones has created 400 kilometers [249 miles] of dead and badly damaged mangroves in the Gulf of Carpentaria, a scientific monitoring trip has discovered. Prof Norman Duke, of James Cook University, spent 10 days […]
