In a landmark public health finding, a new study from the Harvard School of Public Health finds that carbon dioxide (CO2) has a direct and negative impact on human cognition and decision-making. These impacts have been observed at CO2 levels that most Americans — and their children — are routinely exposed to today inside classrooms, offices, homes, planes, and cars.
Changing the distribution of predators and prey in an ecosystem can turn things upside down.
We all know that biodiversity is an important feature of our planet. Two papers published last week provide fascinating illustrations of why that is so.
Losing Big Fish Means More CO2 in the Atmosphere

Existing power plants around the world will pump out more than 300 billion tons of carbon dioxide over their expected lifetimes, significantly adding to atmospheric levels of the climate-warming gas, according to UC Irvine and Princeton University scientists.
Existing power plants across the globe will emit over 300 billion tons of carbon dioxide into the atmosphere before they retire, according to a new study published Tuesday.
The new research, as reported by Science Daily, is also the first to quantify how fast these “baked in” emissions are growing as more power plants are constructed — roughly four percent a year. That’s a problem because it means construction of new fossil fuel-burning power plants is outdistancing the rate at which old ones are being taken offline.
