Current atmospheric models underestimate the dirtiness of Arctic air
2016-05-25 17:32:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Black carbon aerosols--particles of carbon that rise into the atmosphere when biomass, agricultural waste, and fossil fuels are burned in an incomplete way--are important for understanding climate change, as they absorb sunlight, leading to higher atmospheric temperatures, and can also coat Arctic snow with a darker layer, reducing its reflectivity and leading to increased melting. Unfortunately, current simulation models, which combine global climate models with aerosol transport models, consistently...

Climate models underestimate global warming by exaggerating cloud brightening
2016-04-08 07:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Researchers at Lawrence Livermore National Laboratory and Yale University have found that climate models are aggressively making clouds "brighter" as the planet warms. This may be causing models to underestimate how much global warming will occur due to increasing carbon dioxide. The research appears in the April 8 edition of Science. As the atmosphere warms, clouds become increasingly composed of liquid rather than ice, making them brighter. Because liquid clouds reflect more sunlight back to...

Climate forecasts underestimate sea-rise impact of Antarctic thaw
2016-03-31 15:08:02| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Sea levels could rise 50 cm (20 inches) more this century than had been expected, according to a report published on Wednesday which found that Antarctic ice will melt faster than previously thought. Climate scientists at two U.S. universities said the most recent U.N. report on the effects of global warming had underestimated the rate at which the ice covering the continent would melt. That report, issued in 2013, said the worst case of man-made climate change would mean a sea-level rise of...

Cramer: Don't Underestimate Jobs Report Impact on Fed
2016-03-05 00:21:33| Appliances - Topix.net
Editor's Note: This article was originally sent to Action Alerts PLUS subscribers on March 4 at 11:51 a.m. The U.S. economy added 242,00 jobs in February, well above expectations for 200,000, with the enthusiasm somewhat contained by weaker-than-expected wage growth. While the quality of the headline number is up for debate, there is no question that the report set a new market consensus around the timing of the Fed's rate hike: Fed fund futures markets are pricing a near 70% probability of a rate hike this year, vs. 55% probability earlier in the week.
Asset Managers Underestimate the Full Potential of LED Airfield Lighting
2015-09-29 01:00:00| Airport Technology
Airports drive economic development, and are key indicators of a region's economic power. With economic growth, passenger and freight traffic increases. The complexity of airfield lighting systems mirrors air traffic development.
