A new study finds volcanic activity played a direct role in triggering extreme climate change at the end of the Triassic period 201 million year ago, wiping out almost half of all existing species. The amount of carbon dioxide released into the atmosphere from these volcanic eruptions is comparable to the amount of CO2 expected to be produced by all human activity in the 21st century.
Monsoon rainfall has become more unpredictable in India. Floods and droughts have become more common and pose multiple risks to human health and wellbeing, with children under five being particularly vulnerable. New research finds that more assistance needs to be provided to communities in flood-prone areas to protect children under 5 from undernutrition.
First detailed study of scenarios for how wind energy can expand to 20 percent of total US electrical supply by 2030. Results showed expansion of installed capacity makes small impact on efficiency and local climate by deploying next generation, larger wind turbines. Simulations conducted on DOE NERSC Cori supercomputer, analyzed on XSEDE-allocated Jetstream and Wrangler systems. Improved calculations of US wind resources can ensure better decision making and a better, more robust energy supply.
A 12-year study of 166 estuaries in south-east Australia shows that the waters of lakes, creeks, rivers and lagoons increased 2.16 degrees in temperature and increased acidity. Researchers say this could impact economic activity and biodiversity worldwide.
Cloud cover is often characterized in simple terms, such as cloudy, partly cloudy or clear. This does not provide accurate information for estimating the amount of sunlight available for solar power plants. In this week's Journal of Renewable and Sustainable Energy, a new method is reported for estimating cloud optical properties using data from recently launched satellites. This new technique is known as Spectral Cloud Optical Property Estimation, or SCOPE.
NASA's Terra satellite passed over the Southern Pacific Ocean and captured a visible image of extra-tropical cyclone Harold.
powerful Tropical Cyclone Harold from the Solomon Islands to the island of Tonga in the South Pacific. Satellite data was used to calculate the rainfall generated as Harold moved through the Southern Pacific Ocean. NASA also provided infrared imagery on Harold.
On April 8, Tropical Cyclone Harold is a major hurricane, a Category 4 on the Saffir-Simpson Hurricane Wind Scale, as it exits Fiji and heads toward the island of Tonga. NASA used satellite data to calculate the rainfall generated by this powerful and destructive storm in the Southern Pacific Ocean.
Parents who are using popular low-riding pushchairs could be exposing their babies to alarming levels of air pollution, finds a new study from the University of Surrey.
New research published by NUI Galway's Centre for Climate & Air Pollution Studies (C-CAPS) has shone light on the impact of clouds on climate change. The study has raised serious doubts of the likely impact of human-led interventions involving methods of cloud 'brightening' to counteract climate change. The new study has been published today in the Nature's journal - Climate and Atmospheric Science.
