The Nenana Ice Classic provides a consistent and accurate dataset on river ice breakup timing, showing spring is coming earlier due to climate change. Researchers can use this historical record to analyze the effects of global warming on natural systems.
Research shows waves in southern California and the North Pacific have increased in size and intensity over the past half century due to stronger wind and storm activity. The approach direction of winter ocean swells has rotated from northwesterly to westerly, reducing natural sheltering effects and increasing direct impacts on the coast.
Researchers at Purdue University link economic growth to annual hard frosts, finding that temperate areas have historically had less disease and better agricultural productivity. Frost enables the build-up of organic matter in fertile topsoil, allowing for richer agricultural success.
Satellite data confirms that plant life above 40 degrees north latitude has been growing more vigorously since 1981, with Eurasia showing more pronounced greening than North America. The existing vegetation has increased in density, but the area of vegetation has not extended.
The Tropical Rainfall Measuring Mission (TRMM) spacecraft will continue to provide vital data on global rainfall and climate change with its extended mission. Scientists anticipate improved climate predictions and a more robust record of rainfall patterns.
Research found that heavy rainfall precedes most waterborne disease outbreaks in the US, with extreme precipitation levels increasing outbreak risk. The study analyzed data from 1948-1994 and found a significant association between precipitation and waterborne disease outbreaks.
A new technique uses GPS signals to collect environmental data, reducing the size and cost of instrumentation. The system is promising for studying ocean-related conditions and global climate change, with potential applications in satellite systems and unmanned aerial vehicles.
