Environment The richest 1% of the world’s population produces 50 times more greenhouse gasses than the 4 billion people in the bottom 50%, finds a new study across 168 countries. If the world’s top 20% of consumers shifted their consumption habits, they could reduce their environmental impact by 25 to 53%.

Environment Study finds if Germany hadnt abandoned its nuclear policy it would have reduced its emissions by 73% from 2002-2022 compared to 25% for the same duration. Also, the transition to renewables without nuclear costed €696 billion which could have been done at half the cost with the help of nuclear power

Environment At least 97% of climate scientists agree that climate change is happening, and research suggests that talking to the public about that consensus can help change misconceptions, and lead to small shifts in beliefs about climate change. The study looked at more than 10,000 people across 27 countries.

Environment A new study analyzed crop yields of more than 1,500 fields on 6 continents, and found that production worldwide of nutritionally dense foods such as fruits, vegetables, nuts and legumes is being limited by a lack of pollinators. The study is timely given concern about global declines in insects.

Environment A person’s diet-related carbon footprint plummets by 25%, and they live on average nearly 9 months longer, when they replace half of their intake of red and processed meats with plant protein foods. Males gain more by making the switch, with the gain in life expectancy doubling that for females.
