Climate Wildfires A wildfire is an uncontrolled fire in an area of combustible vegetation that occurs in the countryside or a wilderness area. Wildfires occur on every continent except Antarctica. Wildfires are a common occurrence in Australia and the far US west. Concerns continue to grow about the effects of climate change on fire. Wildfires are expected to increase 50 percent across the United States under a changing climate, over 100 percent in areas of the West by 2050 as projected by some studies. A new article published in the journal Forest Ecology and Management by U.S. Forest Service scientists synthesizes recent findings on the interactions between fire and climate and outlines future research needs. Authored by research meteorologists Yongqiang Liu and Scott Goodrick from the Forest Service Southern Research Station (SRS) and Warren Heilman from the Northern Research Station, the article homes in on the effect of emissions from wildfires on long-term atmospheric conditions.
Arctic Ocean Rapidly Acidifying After three years of ongoing research by an international team of scientists, a study commissioned by the Arctic Monitoring and Assessment Programme for a first-ever comprehensive assessment of Arctic Ocean acidification was presented last week at a meeting of Arctic Council Ministers in Bergen, Norway. The research show that the cold waters of the Arctic sea are more vulnerable to acidification. Cold water more readily absorbs CO2 and combined with the precipitous drop in summer sea ice extent, thus exposing more open water, northern oceans are rapidly acidifying.
Great Lakes Losing Water, Climate Change a Significant Factor Great Lakes water levels are at historic lows, 26 inches below their long term averages, raising prices right at the beginning of the supply chain for iron ore, grain, and coal. For every inch the water levels fall, a freighter needs to leave another 100 tons of goods behind on the dock. That means one of the cheapest and most efficient ways to move freight in the world becomes less efficient and more expensive as the water levels drop.
It's important to note that over 160 million tons of goods are carried on the Great Lakes each year, keeping our nation's industrial belt supplied with raw materials. When ships carry less cargo, the cost per delivered unit increases even before the ore gets turned into steel, translating directly to higher cost for manufacturers and consumers.
Climate Change and Man 's Evolution Climate change is bad yet it happens whether we like or not. Then again it may not be so bad. Rapid climate change during the Middle Stone Age, between 80,000 and 40,000 years ago, during the Middle Stone Age, sparked surges in cultural innovation in early modern human populations, according to new research. The research, published this month in Nature Communications, was conducted by a team of scientists from Cardiff University's School of Earth and Ocean Sciences, the Natural History Museum in London and the University of Barcelona.
Texas Legislature Passes Commercial and Industrial PACE Bill The Texas House and Senate passed Senate Bill 385 in May. If Governor Rick Perry approves the bill, the state will break new ground by developing plans for commercial and industrial property assessed clean energy (PACE) programs. This bill will redesign Texas's approach to PACE, focusing on the commercial and industrial sectors rather than on residential programs. The legislation covers both energy efficiency and water efficiency. To facilitate local decision making, cities and local areas will partner with businesses and nonprofits to set up their own PACE programs. These programs will allow businesses to borrow money from private lenders and repay it yearly via an assessment on their property taxes.
