The TRMM satellite is continuing to collect data on various climate and weather questions, including the formation of snowflakes and raindrops inside clouds. Microscopic dust and soot particles are found to interfere with rain formation in 'dirty' clouds.
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.

Researchers at NOAA's National Climate Data Center found evidence that the rate of global warming is accelerating, with recent record high temperatures surpassing expectations. The study analyzed data from 1997 to 1999 and concluded that the rate of warming since 1976 is greater than previously predicted.

Scientists have reported a striking decline in Arctic sea ice thickness since the 1960s, with an average reduction of 4.3 feet. The study analyzed data from three autumn cruises and found a perennial ice cover of 1-3 meters, significantly thinner than previous estimates.
The study adds 1998 data to a two-decade global temperature trend, showing significant warming in the troposphere and cooling in the lower stratosphere. The results contradict past claims that the lower tropospheric data show no warming trend.
A new statistical analysis of 115 years of global temperature data strengthens the argument that human-caused emissions are warming the earth's atmosphere. The study found strong year-to-year correlations between actual temperature data and simulations from two leading computer models, indicating a consistent long-term trend.
