Australia drying caused by greenhouse gases, study shows

ScienceDaily: The agreement between observed and model simulated rainfall changes supports the idea that human activity contributed to the drying of southwestern Australia and that the drying will increase in the 21st century. Changes in fall-winter rainfall from observations (top panel) as compared to model simulation of the past century (middle panel), and a model projection of the middle of the 21st century.

Computer Models Says Australia Drying Due To Ozone Depletion, Greenhouse Gases
2014-07-13 19:35:00| Climate Ark Climate Change & Global Warming Newsfeed
Science 2.0: A new climate model says that southwestern Australia's long-term decline in fall and winter rainfall is caused by increases in man-made greenhouse gas emissions and ozone depletion. NOAA researchers conducted several climate simulations using their global climate model to study long-term changes in rainfall in various regions across the globe. One of the most striking signals of change emerged over Australia, where a long-term decline in fall and winter rainfall has been observed over parts of...

Texas, leader in greenhouse gases, stands vulnerable their effects
2014-07-13 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: As Republicans promote the states economic miracle, many climate scientists from Texas say prosperity has come at a steep price. With its dependence on an energy industry that relies on extracting fossil fuels, scientists say Texas has become a large contributor to greenhouse gas emissions as well as more vulnerable to its consequences. Texas emits more greenhouse gases than any other state, according to federal data. State Republican leaders, however, have questioned whether the earth is...

Australia: Coalition expected to drop refrigerant gases from carbon tax repeal laws

Guardian: Refrigerant gases have apparently been struck out of the carbon tax repeal bills legal requirement for price cuts to be passed on to consumers, even though they were at the centre of the Abbott oppositions dire warnings about price hikes. As opposition leader, Tony Abbott repeatedly warned that big increases in the cost of refrigerant gases would flow straight through to the price of food and other goods. It is a hit on their refrigerant costs. Refrigerant gases are going up almost five...

EPA to Restrict More Greenhouse Gases
2014-07-11 06:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Hill: The Environmental Protection Agency (EPA) proposed Thursday a ban on some uses of hydrofluorocarbons (HFCs), compounds that are used in cooling systems and aerosols but are also extremely potent greenhouse gases. The EPA is moving to ban the substances under a section of the Clean Air Act that allows restrictions on the use of some pollutants when viable alternatives exist. Certain HFCs would be prohibited in vehicle air conditioning, food refrigeration and aerosol propellant applications. The...
