A longer dry season in the Congo Rainforest – “Dry season length is one of the most crucial climate limitations for sustaining rainforest”

By Kathryn Hansen 3 July 2019 (NASA) – It is the “rain” in the term “rainforest” that makes possible the diverse ecosystem teeming with plants and animals. That doesn’t mean a rainforest is always wet: tropical rainforests are known for having distinct wet and dry seasons. But new research shows that the summer dry season in the […]

Almost 600 plant species have already gone extinct – “Plant extinction is bad news for all species”

By Amanda Gonzalez Bengtsson 11 June 2019 (Stockholm University) – For the first time ever, scientists at the Royal Botanic Gardens, Kew and Stockholm University, have compiled a global analysis of all plant extinction records documented from across the world. This unique dataset published today in leading journal, Nature Ecology & Evolution, brings together data […]

Projected change in population density in Ethiopia by 2050 under a pessimistic climate change scenario. As climate change worsens even moderately, it could cause water shortages in Ethiopia severe enough to prompt 1.5 million Ethiopians to migrate by 2050. They’ll most likely move out of the northern highlands and Addis Ababa into the southern highlands and Ahmar Mountains. Addis Ababa lies at the center of Ethiopia’s agricultural region, and lower crop yields will result in movement out of the urban center, which is currently the hub of the country’s economic development.

Get ready for tens of millions of climate refugees

By Susan Cosier 24 April 2019 (Technology Review) – In 2006, the British economist Nicholas Stern warned that one of the biggest dangers of climate change would be mass migration. “Climate-related shocks have sparked violent conflict in the past,” he wrote, “and conflict is a serious risk in areas such as West Africa, the Nile […]

World’s rivers awash with dangerous levels of antibiotics – “It’s quite scary and depressing”

By Natasha Gilbert 26 May 2019 (The Guardian) — Hundreds of rivers around the world from the Thames to the Tigris are awash with dangerously high levels of antibiotics, the largest global study on the subject has found. Antibiotic pollution is one of the key routes by which bacteria are able develop resistance to the […]

Climate change has worsened global economic inequality – “Most of the poorest countries on Earth are considerably poorer than they would have been without global warming,”

By Josie Garthwaite 22 April 2019 (Stanford University) – A new Stanford University study shows global warming has increased economic inequality since the 1960s. Temperature changes caused by growing concentrations of greenhouse gases in Earth’s atmosphere have enriched cool countries like Norway and Sweden, while dragging down economic growth in warm countries such as India and Nigeria.

Only one-third of the world’s longest rivers remain free-flowing – Nearly 60,000 large dams exist worldwide, with more than 3,700 planned

Only one-third of the world’s longest rivers remain free-flowing – Nearly 60,000 large dams exist worldwide, with more than 3,700 planned

8 May 2019 (McGill University) – Just over one-third (37%) of the world’s 246 longest rivers remain free-flowing, according to a new study published in the scientific journal Nature. Dams and reservoirs are drastically reducing the diverse benefits that healthy rivers provide to people and nature across the globe. A team of 34 international researchers from McGill University, […]

New study establishes link between climate change, conflict, and migration – “In a context of poor governance and a medium level of democracy, severe climate conditions can create conflict over scarce resources”

23 January 2019 (UEA) – Research involving a University of East Anglia (UEA) academic has established a link between climate change, conflict, and migration for the first time. In recent decades climatic conditions have been blamed for creating political unrest, civil war, and subsequently, waves of migration, but scientific evidence for this is limited. One […]
