An international team of researchers including the University of Adelaide has demonstrated that climate change is responsible for the changes in the flow and water volume of rivers globally, with major implications for Australia.
Where does snow come from? This may seem like a simple question to ponder as half the planet emerges from a season of watching whimsical flakes fall from the sky--and shoveling them from driveways. But a new study on how water becomes ice in slightly supercooled Arctic clouds may make you rethink the simplicity of the fluffy stuff. It describes definitive, real-world evidence for "freezing fragmentation" of drizzle as a major source of ice in slightly supercooled clouds. The findings have important implications for forecasting weather and climate.

How did rocks rust on Earth and turn red? A Rutgers-led study has shed new light on the important phenomenon and will help address questions about the Late Triassic climate more than 200 million years ago, when greenhouse gas levels were high enough to be a model for what our planet may be like in the future.
Antarctic ice is melting, contributing massive amounts of water to the world’s seas and causing them to rise – but that melt is not as linear and consistent as scientists previously thought, a new analysis of 20 years’ worth of satellite data indicates.
Methane (CH4) is the second most important greenhouse gas after carbon dioxide (CO2).
A first-of-its-kind, international study of 107,000 children finds that higher temperatures are an equal or even greater contributor to child malnutrition than the traditional culprits of poverty, inadequate sanitation, and poor education. The 19-nation study is the largest investigation to date of the relationship between our changing climate and children's diet diversity. Of the six regions examined--in Asia, Africa, and Central and South America--five had significant reductions in diet diversity associated with higher temperatures.
The planet is committed to global warming in excess of 2 degrees Celsius (3.6°F) just from greenhouse gases that have already been added to the atmosphere. This is the conclusion of new research by scientists from Nanjing University, Lawrence Livermore National Laboratory (LLNL) and Texas A&M University, which appears in the latest edition of Nature Climate Change.

Until humans can find a way to geoengineer ourselves out of the climate disaster we’ve created, we must rely on natural carbon sinks, such as oceans and forests, to suck carbon dioxide out of the atmosphere. These ecosystems are deteriorating at the hand of climate change. Once destroyed, they may not only stop absorbing carbon from the atmosphere, but start emitting it.
On top of rising sea levels, stronger hurricanes and worsening wildfires, scientists project that human-caused climate change will result in one of the most dire consequences imaginable: a disruption in the global beer supply.
New study indicates common satellite imaging technologies vastly underestimate number of fires in Florida, detecting only 25 percent of burn area.
