After weeks of speculation, President Barack Obama officially announced his selections to lead the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) on Monday. Gina McCarthy was chosen to lead the EPA, replacing Lisa Jackson, while Ernest Moniz will take over as energy secretary, replacing Steven Chu. Together, Obama said, they are charged with "making sure that we're investing in American energy, that we're doing everything that we can to combat the threat of climate change." They join Sally Jewell, named to the Department of the Interior last month. Jewell's confirmation hearing is slated to take place today.
Assuming Moniz and McCarthy win confirmation from the Senate, what can we expect them to focus on? Using the power of executive authority, quite a bit, reports The Washington Post. On the list: reducing global hydrofluorocarbon emissions, tightening emissions from medium and heavy-duty vehicles, new energy efficiency standards, and using the Clean Air Act pursue stricter rules for natural gas and methane emissions and cap greenhouse gas emissions from power plants.
For the last four years, McCarthy has been working with the EPA as the assistant administrator for the Office of Air and Radiation. Under her leadership, the EPA proposed the first regulations to cap emissions from new power plants under the Clean Air Act in 2012 and the Mercury and Air Toxic Standards (MATS) in 2011. A large number of pollution rules that have been postponed or delayed in the courts -- such as the cross state air controls for power plants -- will come up in Obama's second term. In this new role McCarthy could face considerable opposition from industry polluters, which some say could be worse than her predecessor.
Moniz, director of the Massachusetts Institute of Technology's Energy Initiative, is a former Energy Department undersecretary. "Ernie knows that we can produce more energy and grow our economy while still taking care of our air, water and our climate," Obama said when he introduced Moniz Monday. The nomination of the MIT physicist comes with mixed reactions, as Moniz is a known advocate of shale gas and nuclear energy. The coal industry, however, is much more welcoming of Moniz than McCarthy, GreenWire reports (subscription required) because making coal fit into a low-carbon world has been a focus of his research.
Climate Change to Open Arctic Shipping Routes
As a result of climate change, by mid-century, ships could sail directly over the North Pole, according to a new study. The Northwest Passage is now only accessible to a few icebreaker ships on average one summer of every seven years. Through computer simulations using independent climate forecasts for the years 2040 to 2059, researchers at the University of California, Los Angeles, predict the route -- 20 percent short than today's most trafficked Arctic shipping lane -- to be passable more frequently with warming of the North Pole that will lead to record low levels of summer sea ice.
"The development is both exciting from an economic development point of view and worrisome in terms of safety, both for the arctic environment and for the ships themselves," said lead researcher Laurence Smith, who mapped the likeliest routes, usable by icebreakers and other open water vessels, during the month of September. The price of oil and locations of natural gas will be big determinants for whether or not Arctic navigation increases, the authors said. Numerous obstacles, aside from sea ice, stand in the way of increased navigation in the region. Just last month, Shell called off drilling exploration efforts after several mishaps.
House Votes to Increase Funds for Satellite
Sequester budget cuts had threatened to impose a two- to three-year delay in the production and deployment of the first next-generation weather satellites being developed by National Oceanic and Atmospheric Administration (NOAA) through a program called GOES-R. Wednesday, the House of Representatives voted to approve legislation that could breathe new life into the program that aims to create more timely and accurate weather forecasts. The spending bill would set aside $802 million for NOAA's satellites. The catch? Tt must be approved by the Senate, and even if passed the new figure is still subject to additional cuts.
Record Carbon Dioxide Spike
Researchers at NOAA say the amount of carbon dioxide in the atmosphere rose significantly in 2012. Carbon dioxide levels jumped by 2.67 parts per million since 2011 to a total just under 395 parts per million and could make it unlikely global warming can be limited another 2 degrees Celsius. The spike is the second highest since record keeping began in 1959, surpassed only by the 1998 increase of 2.93 parts per million.
