Humans are disrupting natural “salt cycle” on a global scale

31 October 2023 (University of Maryland) – The influx of salt in streams and rivers is an ‘existential threat,’ according to a research team led by a UMD geologist. The planet’s demand for salt comes at a cost to the environment and human health, according to a new scientific review led by University of Maryland Geology Professor Sujay Kaushal. Published […]

The Mississippi River is losing its fight with the ocean – “This is not a one-off or once-in-100-years thing”

By Nancy Walecki 11 October 2023 (The Atlantic) – The mouth of the Mississippi River is the arena for a kind of wrestling match. In one corner of the ring is the salt water of the Gulf of Mexico, and in the other, the river’s fresh water. The two shove against each other, and usually, […]

Pacific island sea levels rising faster than global average, WMO says – Economic damage in Southwest Pacific due to flooding in 2022 was $8.5 billion, almost triple compared to the previous year

By Gabrielle Tétrault-Farber 17 August 2023 GENEVA (Reuters) – Sea levels in the South-West Pacific are rising faster than the global average, threatening low-lying islands while heat damages marine ecosystems, the U.N. meteorological agency said on Friday. In its State of the Climate in the South-West Pacific 2022 report, the World Meteorological Organization (WMO) said […]

Ghost forests: coastal forests dying off as sea-level rise accelerates

By Ginger Zee, Daniel Manzo, and Kelly Livingston 6 July 2023 (ABC News) – As people around the world contend this week with the hottest temperatures ever recorded on Earth, more visual evidence of climate change is emerging with the spread of ghost forests. The globe is naturally warming and seas naturally rise, but greenhouse […]

During a full moon, the sea invades the river with such strength that, in some places, it turns into a single giant wave of up to 4 meters (13 feet), a phenomenon known as pororoca.

Climate migration: Açai growers flee salty Amazon water – “The village is approaching its end”

By Fabiano Maisonnave and Eraldo Peres 10 November 2022 MACAPA, Brazil (AP) – Where the mother of all rivers meets the Atlantic Ocean in coastal Brazil, it’s not a single channel, instead it braids around 230 kilometers (142 miles) of islands including the Bailique Archipelago. A native of the mouth of the Amazon, Elielson Elinho, […]

Politics, climate conspire as Tigris and Euphrates dwindle – “Life has ended here”

By Samya Kullab 18 November 2022 DAWWAYAH, Iraq and ILISU DAM, Turkey (AP) – Next year, the water will come. The pipes have been laid to Ata Yigit’s sprawling farm in Turkey’s southeast connecting it to a dam on the Euphrates River. A dream, soon to become a reality, he says. He’s already grown a […]

Hoof prints left by Camargue bulls mark a section of pasture encrusted with salt on the Raynaud ranch in Camargue, southern France, 23 September 2022. As soil salt levels rise due to drought and reduced river flow from the Rhone River, the land traditionally used by bull breeders like the Raynaud family is becoming more and more difficult to maintain as a suitable pace to raise animals.

In southern France, drought, rising seas threaten traditions – “The sea level rises on our coast and takes more and more of our land”

By Daniel Cole 30 October 2022 SAINTES-MARIE DE LA MER, France (AP) – In a makeshift arena in the French coastal village Aigues-Mortes, young men in dazzling collared shirts come face-to-face with a raging bull. Surrounded by the city’s medieval walls, the men dodge and duck the animal’s charges while spectators let out collective gasps. […]

Satellite view of Lake Tuz in Turkey acquired on 23 October 2021. Lake Tuz is Turkey's second-largest lake and home to several bird species. During the summer of 2021, the lake completely dried up causing the death of thousands of flamingos and other bird species that inhabit the lake. Experts attribute the extreme drought in eastern Turkey to climate change. Photo: European Union / Copernicus Sentinel-2 imagery

Haunting satellite imagery shows Turkey’s second-largest lake has dried up

By Molly Taft 2 November 2021 (Gizmodo) – A new satellite image of Turkey’s Lake Tuz is gorgeous—and, if you know more about what it’s portraying, worrying. The stunning capture from the European Space Agency’s Sentinel-2 satellite shows Turkey’s second-largest lake has completely dried up this year, exposing a haunting expanse of salt. While Lake Tuz, one of the world’s largest saltwater lakes, […]

Sea level rise is killing trees along the Atlantic coast, creating “ghost forests” that are visible from space

By Emily Ury 6 April 2021 (The Conversation) – Trekking out to my research sites near North Carolina’s Alligator River National Wildlife Refuge, I slog through knee-deep water on a section of trail that is completely submerged. Permanent flooding has become commonplace on this low-lying peninsula, nestled behind North Carolina’s Outer Banks. The trees growing in […]

World food security increasingly at risk due to “unprecedented” climate change impact, new UN report warns

8 August 2019 (UN News) – More than 500 million people today live in areas affected by erosion linked to climate change, the UN warned on Thursday, before urging all countries to commit to sustainable land use to help limit greenhouse gas emissions before it is too late. Speaking at the launch of a Special […]
