Gulf of Mexico could see record 'dead zone'

The Gulf of Mexico could see a record-size dead zone this year of oxygen-deprived waters resulting from pollution, US scientists have cautioned based on government data models.

How do you feed 9 billion people?

An international team of scientists has developed crop models to better forecast food production to feed a growing population – projected to reach 9 billion by mid-century – in the face of climate change.

NASA image: Agricultural fires in western Mexico

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite detected dozens of fires burning in western Mexico on May 30, 2013. The fires are outlined in red.

Coccoliths thrive despite ocean acidification

Ocean acidification is damaging some marine species while others thrive, say scientists. An international team studied the effect of ocean acidification on plankton in the North Sea over the past forty years, to see what ...

Surprising predictor of ecosystem chemistry

Carnegie scientists have found that the plant species making up an ecosystem are better predictors of ecosystem chemistry than environmental conditions such as terrain, geology, or altitude. This is the first study using ...

Maple syrup, moose, and the local impacts of climate change

In the northern hardwood forest, climate change is poised to reduce the viability of the maple syrup industry, spread wildlife diseases and tree pests, and change timber resources. And, according to a new BioScience paper ...

NOAA: Gulf of Mexico 'dead zone' predictions feature uncertainty

A team of NOAA-supported scientists is predicting that this year's Gulf of Mexico hypoxic zone could range from a low of approximately 1,197 square miles to as much as 6,213 square miles. The wide range is the result of using ...

Seasonal algae plays critical role in North Pacific carbon uptake

The role of the North Pacific Ocean as a net carbon sink may prove to be more precarious than previously thought as researchers work to isolate the contributions of biological and physical processes to air-sea gas exchange. ...
