Wildfires to Become Bigger, Smokier and More Frequent by 2050
2013-08-29 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Wildfires will burn longer, wider and create more smoke by the year 2050, according to a new study by Harvard University researchers that brings with it some bad news for fire crews battling blazes across the western United States. California's Rim Fire, for instance, has burned nearly 200,000 acres of forest since it ignited two weeks ago and fire crews don't expect to have the largest active wildfire in the country contained for another two weeks to come. If predictions made by the Harvard...

High-Shear Mixers are Suitable for Frequent Formulation Changeovers
2013-08-27 14:35:00| Chemical Processing
Charles Ross & Sons inline high-shear mixers are suitable for general-purpose mixing, powder wet-out, particle size reduction, solubilization emulsification and homogenization. This type of device features a four-blade rotor running within a close-tolerance fixed stator at tip speeds in the range of 3,000 to 4,000 ft/min.

Climate change to trigger frequent, severe heatwaves
2013-08-18 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Press Trust of India: Climate change is set to trigger more frequent and severe heatwaves in the next 30 years regardless of the amount of carbon dioxide (CO2) emitted into the atmosphere, a new study has warned. Extreme heat waves such as those that hit the US in 2012 and Australia in 2009 dubbed three-sigma events by the researchers are projected to cover double the amount of global land by 2020 and quadruple by 2040, researchers said. Meanwhile, more-severe summer heat waves classified as five-sigma events will...

More Frequent Heat Waves by 2020 Almost Certain
2013-08-18 15:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: Stand by for extreme weather. Prepare for heat waves on a scale that was once unprecedented. For once, there are no "ifs' in the forecast, no caveats about modeling business-as-usual-scenarios rather than dramatic reductions of emissions for near-term warming Even if governments abandon fossil fuels everywhere, immediately, and invest only in green energy, there will be new record temperatures. The greenhouse gas emissions of the last few decades now mean that regions of the planet subjected to...

Global Warming Linked with Frequent Fires in Alaska's Boreal Forests
2013-07-23 15:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: A new study from the University of Illinois has shown that Yukon Flats of interior Alaska, one of the most flammable regions of the world, is seeing more frequent and severe fires now than it had in the past 10,000 years. Researchers attribute this increase to global warming. Recently, large wildfires in Alaska have charred more than half a million acres at a time, The Los Angeles Times reported. Another recent study had found that wildfires may drive up global warming by releasing more carbon-containing...
