Relating the trees in the Amazon to west coast droughts
November 7, 2013 02:09 PM - Morgan Kelly, Princeton University
In research meant to highlight how the destruction of the Amazon rainforest could affect climate elsewhere, Princeton University-led researchers report that the total deforestation of the Amazon may significantly reduce rain and snowfall in the western United States, resulting in water and food shortages, and a greater risk of forest fires.
Tesla in the Mass Market
November 7, 2013 08:42 AM - MoveForward, Electric Forum
Tesla Motors is a company, which seems to go from strength to strength and indeed to all intents and purposes this is a company, which has dragged the electric vehicle market kicking, and screaming to the point of mass acceptance. Anybody who has even looked at electric vehicles will be well aware that Tesla began life at the top end of the luxury car market and once this particular niche was dominated the company began to look further down the electric car food chain.
Ice Cores may yield 1.5 million year climate record
November 7, 2013 06:11 AM - ScienceDaily
How far into the past can ice-core records go? Scientists have now identified regions in Antarctica they say could store information about Earth's climate and greenhouse gases extending as far back as 1.5 million years, almost twice as old as the oldest ice core drilled to date. The results are published this week in Climate of the Past, an open-access journal of the European Geosciences Union (EGU). By studying the past climate, scientists can understand better how temperature responds to changes in greenhouse-gas concentrations in the atmosphere. This, in turn, allows them to make better predictions about how climate will change in the future.
Deep sea Drilling in New Zealand
November 6, 2013 01:51 PM - Rachel Shaw, The Ecologist
Deep sea drilling will soon commence in the rough waters off the New Zealand coast. This could mark the beginning of an oil rush in which democratic process, public concern, environmental protection and safety considerations are all swept aside. The Exclusive Economic Zone (EEZ) around New Zealand is fifteen times larger than the country's land area - it extends from the sub-tropical to the sub-Antarctic. Like the Arctic, New Zealand's EEZ supports a multitude of species which travel from far-flung areas of the globe to reach these rich waters. Like the Arctic, New Zealand's EEZ is fast becoming an oil exploration frontier.
While the US electric car market continues to grab the headlines it is worth remembering that Norway is by far and away the leading electric car loving country with the highest ratio of electric vehicles per capita. Indeed many in the industry refers to Oslo as the capital of the electric vehicle industry and if you take a look at the situation you will see there are a number of reasons why electric vehicles are so popular in the country. In many ways it seems that a number of factors have come together to create the perfect storm for electric vehicles in some parts of Scandinavia. If we take a look at Norway there are many reasons to be cheerful if you are an electric vehicle retailer. A gallon of gasoline in Norway costs in excess of $10 despite the fact the country is awash with oil and gas from its surrounding oilfields. Fuel is not subsidised at the pumps as the government uses the massive oil and gas income to extend and improve the country’s infrastructure. This is perhaps one of the main drivers as to why the number of electric vehicles across Norway continues to grow, and seems likely to for some time to come.
2013 PCB dredging on the Hudson
November 5, 2013 02:50 PM - Editor, ENN
The U.S. Environmental Protection Agency today announced that more than 612,000 cubic yards of river bottom sediment contaminated with PCBs were removed from the upper Hudson River during 2013, exceeding the annual goal of 350,000 cubic yards for this historic dredging project. This is similar to the amount dredged in 2012 when more than 650,000 cubic yards were removed. The Superfund cleanup required by the EPA calls for the dredging of approximately 2.65 million cubic yards of PCB-contaminated sediment from a 40-mile stretch of the upper Hudson River between Fort Edward and Troy, New York. The project began in 2009 and is about 73% complete, putting the dredging on track to be finished in two years. To date, about 1.9 million of the 2.65 million cubic yards million have been removed. Filling of previously dredged areas with clean sand and gravel will continue over the next several weeks, weather permitting. About 280 local area contractors, subcontractors, vendors and suppliers have provided goods or services related to Hudson River dredging.
The Juncture of Politics and the Environment
November 5, 2013 08:41 AM - Duncan Jefferies, Triple Pundit
When announcing his plan to kick-start the U.S. economy in the midst of the Great Depression, Franklin D. Roosevelt famously declared that the country had "nothing to fear but fear itself." In just 100 days, through a flurry of legislation and investment, his government dragged the country up off its knees — a towering political achievement.
We're burying ourselves in our own garbage
November 5, 2013 07:07 AM - Population Matters from Nature
Solid waste — the stuff we send down our chutes, discard at work and put on the curb every week — is a striking by-product of civilization. The average person in the United States throws away their body weight in rubbish every month. When waste management works well, we give it little thought: out of sight and, usually, quickly out of mind. Discarded materials are collected, some are recycled or composted, and most are landfilled or incinerated. But the global view is troubling. In the past century, as the world's population has grown and become more urban and affluent, waste production has risen tenfold. By 2025 it will double again1. Rubbish is being generated faster than other environmental pollutants, including greenhouse gases. Plastic clogs the world's oceans and rivers, causing flooding in developing-world cities. Solid-waste management is one of the greatest costs to municipal budgets.
Do dams bring more harm or more good?
November 4, 2013 09:01 AM - Editor, ENN
As China forges ahead with its goal to generate 120,000 megawatts of renewable energy by 2020, they are damming more and more rivers. According to China, this is a safe strategy that will curb pollution, control floods, and minimize climate change. Conservationists and scientists across the globe however, disagree.
President Obama Signs Executive Order, Addresses Preparedness for Climate Change Impacts
November 4, 2013 06:00 AM - Editor, ENN
On Friday, President Obama established a Task Force on Climate Preparedness and Resilience to advise the Administration on how the Federal Government can respond to the needs of communities nationwide that are dealing with the impacts of climate change. The Executive Order directs federal agencies to modernize Federal programs to support climate-resilient investments, manage me lands and waters for climate preparedness and resilience, provide information, and plan for climate change related risk.
