Study finds global action needed to ensure acceptable climate futures


Ensuring a tolerable climate future, one that reduces warming while considering the costs, requires immediate global action, according to a study published in the journal Nature Climate Change. “The study analyzes climate change as a multi-objective problem,” said CLIMA Director Klaus Keller. “Considering only a goal of tolerable temperature changes misses important aspects. One also needs to consider goals such as tolerable costs and impacts.”

Ask an Ethicist: Does climate change affect genders differently?


Question: Climate change is a global concern and media outlets tend to focus on certain issues such as ice sheet melt, sea level rise, government policies concerning climate change, and greenhouse gas emissions. These are all important issues and, until recently, I didn’t realize there were other concerns that we should be talking about, specifically regarding gender and climate change. So, what ethical concerns exist around gender and climate change?
