US corn yields get boost from a global warming 'hole'

The global average temperature has increased 1.4 degrees Fahrenheit over the last 100 years. In contrast, the Corn Belt of the U.S., one of the most agriculturally productive regions of the world, has experienced a decrease in temperatures in the summer during the growing season. Known as the 'US warming hole,' this anomalous cooling phenomenon, which occurred in tandem with increasing rainfall, was responsible for boosting corn yields by 5 to 10 percent per year, according to a new study.

In any single location, there are typically more earthworms and more earthworm species found in temperate regions than in the tropics. Global climate change could lead to significant shifts in earthworm communities worldwide, threatening the many functions they provide.

What exactly triggers the increase in carbon dioxide concentrations that causes the transition from a glacial stage to a warm stage is not fully understood. Scientists have developed a new model in which the weathering of pyrite, a common mineral containing sulfur, plays a key role.

Why are bald eagles such great gliders? It's all in the wrist

Birds come in an astounding array of shapes and colors. New research helps explain why bird species with similar flight styles or body sizes don't have consistent wing shapes. Bird species tend to reshape the range of motion of their wings — rather than wing shape or size itself — as they evolve new ways of flying.

Climate change could hasten deterioration of US bridge infrastructure

Scientists are studying the toll climate change may take on aging US infrastructure, which includes over 600,000 bridges. A new study links the potential impacts of climate change with the structural integrity of thousands of bridges transecting America's highways and towns. The analysis demonstrates a need to rethink the nation's priority order of bridge repair, as climate change looms and infrastructure funding remains limited.
