11:13 AM | GEOS-5 Computer Model Provides High-Resolution Look at Key Greenhouse Gas
A new computer model called GEOS-5 has provided a high-resolution look at how carbon dioxide (CO2) – the key driver of global warming – moves around the globe and fluctuates in volume throughout the year. This particular simulation is called Nature Run. It is the product of the Goddard Earth Observing System Model, Version 5 [...]

7:33 PM | Volcanic Eruptions May Have Triggered Episodic Water Flow on Ancient Mars
Scientists from Weizmann Institute of Science in Israel and Brown University suggest that water flow and warm temperatures on early Mars were likely related to periodic volcanism that spewed tons of greenhouse-inducing sulfur dioxide into the planet’s atmosphere. The researchers suggest that periods of temperatures warm enough for water to flow likely lasted for only [...]

2:00 PM | Designing California Cities for a Long-Term Drought
Scientists say it’s possible California’s drought may last a lot longer than a few years. No one knows for sure, but we could all simply have to adjust to a drier climate. That could mean changing the way we build cities to make them more porous. The 'Hydramax,' a futuristic design pictured above, rises with the tide and captures water from the air.

12:00 PM | Geosciences Column: Is it possible to quantify the effect of natural emissions on climate?
The air we breathe is full of tiny particles that can have a big impact on our climate. Industrial activities have greatly increased the number of these particles, cooling the climate and potentially offsetting some of the warming due to greenhouse gases. In this post Kirsty Pringle introduces new research that suggests that it might […]

2:00 PM | Parched: California Wildlife Suffers in Drought
Birds, salmon and snakes depend on marshes and rivers for survival and migration, and to propagate the species. But many wildlife species are unable to find the water they need as the drought shrinks rivers and dries up wetlands.

4:46 PM | Latest Forecast: Odds of an El Niño Drop
The odds of an El Niño developing this winter have faded somewhat, further dimming hopes for a break in California’s historic drought. Back in June, forecasters pegged the odds of an El Niño emerging by fall and winter at 80 percent. Today, a bulletin from the National Climatic Data Center reports that the long predicted El Niño […]The post Latest Forecast: Odds of an El Niño Drop appeared first on ImaGeo.
