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

October 24, 2019 0 Comments Agriculture and Food, Climate, Endangered Plants, Environmental Awareness, Environmental Issues, Food and Agriculture, Global Warming, Nature

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.

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.

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.

While studying sediments in the Bay of Bengal, an international team finds evidence dating back millions of years that catastrophic events likely toppled fresh trees from their mountain homes on a long journey to the deep sea. The discovery may add to models of the Earth's carbon cycle.

Climate warming promises more frequent extreme El Niño events

October 21, 2019 0 Comments Climate, El Nino and La Nina, Environmental Awareness, Environmental Issues, Environmental Policy, Geography, Global Warming, Weather

New research, based on 33 historical El Niño events from 1901 to 2017, show climate change effects have shifted the El Niño onset location from the eastern Pacific to the western Pacific and caused more frequent extreme El Niño events since the 1970's. Continued warming over the western Pacific warm pool, driven by anthropogenic climate change, promises conditions that will trigger more extreme events in the future.
