A field study of wheat demonstrates how the nutritional quality of food crops can be diminished when elevated levels of atmospheric carbon dioxide interfere with a plant's ability to process nitrate into proteins.

Rising carbon dioxide levels harm wheat quality by interfering with the plant's ability produce proteins.

Researchers have debated for more than two decades the likely impacts, if any, of global warming on the worldwide incidence of malaria, a mosquito-borne disease that infects more than 300 million people each year.

April 10, 2014 | Climate change will reduce water availability during dry seasons and increase it during wet seasons around the globe, new research suggests. It also finds there will be large regional variations in water-related impacts. Some areas may see an increase in both droughts and floods by the later part of the 21st century.

March 13, 2014 | The pause in global warming since 2001 can be traced to a natural shift in weather patterns that causes stronger trade winds along the equator in the Pacific Ocean, new research indicates. When the patterns change, global temperatures will quickly warm, according to the researchers.
