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 […]

Too much water or too little: Hydropower fights wild weather as climate changes rapidly

By Gerald Porter Jr. and Jeremy Hodges 22 June 2019 (Bloomberg) – The Kariba Dam has towered over one of Africa’s mightiest rivers for 60 years, forming the world’s largest reservoir and providing reliable electricity to Zambia and Zimbabwe.

Global peacefulness improves for first time in five years, but world still less peaceful than a decade ago

12 June 2019 (IEP) – The 13th edition of the annual Global Peace Index (GPI) report, the world’s leading measure of global peacefulness, reveals that the average level of global peacefulness improved for the first time in five years. However, despite improvement, the world remains considerably less peaceful now than a decade ago, with the […]

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 […]

Occurrence of back-to-back heat waves likely to accelerate with global warming – “Compound heat waves are projected to grow more rapidly than simple heat waves”

Occurrence of back-to-back heat waves likely to accelerate with global warming – “Compound heat waves are projected to grow more rapidly than simple heat waves”

By Joseph Albanese 8 May 2019 (Princeton Environmental Institute) – As the planet continues to warm, multi-day heat waves are projected to increase in frequency, length and intensity. The additive effects of these extreme heat events overwhelm emergency service providers and hospital staff with heat-related maladies, disrupt the electrical grid and can even cause delays […]
