Several indicators point to the adverse impacts of climate change on the planet’s vegetation, but a little-known positive fact is the existence of climate-change refugia in which trees are far less affected by the gradual rise in temperatures and changing rainfall regimes. 

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.

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.

Canada’s Manitoba Province jumped right from winter ice to summer fires.

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.

As with many introduced species the beachgrasses come with ecological costs to the native flora and fauna.

Scientists need to work closely with resource management agencies to assess impacts
