Giving children high doses of vitamin D doesn’t appear to reduce the winter sniffles, a new study has found.

In a new study, scientists found that aerosol particles released into the atmosphere from the burning of fossil fuels are a primary driver of changes in rainfall patterns across the globe.

The results of the climate system-model simulations conducted by researchers Brian Soden and Eui-Seok Chung from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science revealed that changes in clouds, as a result of their interaction with these man-made aerosols in the atmosphere, are driving large-scale shifts in rainfall and temperature on Earth.

NASA's Aqua satellite passed over newly formed Tropical Storm Don gathering temperature data from the compact storm's clouds.

Reducing greenhouse-gas emissions is not enough to limit global warming to a level that wouldn’t risk young people’s future, according to a new study by a team of scientists who say we need negative emissions. Measures such as reforestation could accomplish much of the needed CO2 removal from the atmosphere, but continued high fossil fuel emissions would demand expensive technological solutions to extract CO2 and prevent dangerous warming. The study is published today in Earth System Dynamics, a journal of the European Geosciences Union.

Heavy rainfall can cause rivers and drainage systems to overflow or dams to break, leading to flood events that bring damage to property and road systems as well potential loss of human life.

One such event in 2008 cost $10 billion in damages for the entire state of Iowa. After the flood, the Iowa Flood Center (IFC) at the University of Iowa (UI) was established as the first center in the United States for advanced flood-related research and education.
