Global Warming May Cause Spike in Asthma, Allergy Symptoms

A new study finds that exposure to a widespread outdoor fungus can increase cell damage (oxidative stress) in the airways. This spike weakens the airways’ barrier defense system that, when functioning normally, removes infection- and allergy-causing organisms (mucociliary clearance). The study, published ahead of print in the American Journal of Physiology—Cell Physiology, was chosen as [...]

Soils Could Release Much More Carbon Than Expected as Climate Warms

Soils could release much more CO2 than expected into the atmosphere as the climate warms, according to new research by scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). Their findings are based on a field experiment that, for the first time, explored what happens to organic carbon trapped in soil when [...]

Scientists Warn Negative Emissions Are a ‘Moral Hazard’

Removing carbon dioxide emissions from the atmosphere to prevent global warming from becoming catastrophic may be a fool’s game amounting to a “moral hazard par excellence,” according to a paper published Thursday in the journal Science. Nobody knows if atmospheric carbon removal — known as negative emissions — will work, and it could delay critical [...]

100 million roses grown for Valentine’s Day produce 9,000 metric tons of CO2

Roses may be red, but they’re definitely not green according to research from Scientific American. As millions of partners exchange bunches of red roses in the run up to Valentine’s Day, they may want to consider that the traditional flower of love has an environmental impact worse than most other crops. In fact, according to [...]
