“If you can’t measure it, you can’t improve it”. 

The Paleocene-Eocene Thermal Maximum, or PETM, was a short interval of highly elevated global temperatures 56 million years ago that is frequently described as the best ancient analog for present-day climate warming.

USC researchers modeled complex subsurface water flow to help assess the risk of contaminants appearing in high, unsafe concentrations in variable water source.

NASA’s new Earth System Observatory will guide efforts related to climate change, disaster mitigation, fighting forest fires, and improving real-time agricultural processes.

The Annual Greenhouse Gas Index is updated each spring after nearly all the air samples collected during the previous year have been obtained and analyzed.

New insights into how phytochromes help plants sense and react to light, temperature

Rich in quartz, limestone, and algae, the Great Lake is also rich with seasonal color.

New research shows that concentrations of the toxic element mercury in rivers and fjords connected to the Greenland Ice Sheet are comparable to rivers in industrial China, an unexpected finding that is raising questions about the effects of glacial melting in an area that is a major exporter of seafood.

Because of anthropogenic emissions of oxides of nitrogen (NOx), the NOx deposition rate is about five-fold greater than that of pre-industrial times largely due to energy production and biomass burning.

New research shows that this type of wildfire—which can survive the winter to re-emerge in spring—is becoming more common in high northern latitudes as the climate warms.
