Next month, the U.S. Environmental Protection Agency (EPA) will issue a proposed rule that sets the first-ever carbon emissions standards for the country's existing power plants. The rule, to be announced by President Barack Obama, is rumored to include a phased approach leading to steeper emissions limits over time.
Though little has formally come out about the rule, to be released on or around June 2, EPA officials have said it will be flexible.
"It is going to be flexible, and it will set goals," said Curt Spaulding, EPA administrator for New England. "I can't tell you what those goals are going to be--that's being worked on in Washington at the highest levels."
Bloomberg has reported that the administration is considering a two-stage reduction of emissions by 25 percent. The reduction would begin with small cuts; deeper cuts would start in 2024 and run through 2029.
Reports Point Finger at Climate Change for Increased Risks
On the heels of news that last month ranked as the world's hottest April on record--1.39 degrees Fahrenheit warmer than the 20th century average for the month (56.7 degrees Fahrenheit)--new reports are pointing to rising global temperatures for increased threats to the food industry, landmarks and credit ratings.
- A new Standard & Poor's Ratings Services report finds rising temperatures could be bad for a nation's credit rating. The report rates 128 sovereign governments on the basis of creditworthiness, suggesting that poorer countries and nations with already low ratings would be hit hardest by the effects of climate change. Global warming "will put downward pressure on sovereign ratings during the remainder of this century," Standard & Poor analysts wrote. "The degree to which individual countries and societies are going to be affected by warming and changing weather patterns depends largely on actions undertaken by other, often far-away societies."
- Many of the nation's historic and cultural landmarks may be irreparably damaged or lost forever due to the effects of climate change, according to a non-peer-reviewed report by the Union of Concerned Scientists. The Harriet Tubman National Monument in Maryland, the Kennedy Space Center in Florida and the first permanent English settlement in the Americas, Jamestown, are among the 30 sites at risk for rising seas, coastal erosion, increased flooding, heavy rains, wildfire and drought.
- Growth of global food production could be reduced 2 percent each decade for the next century as a result of climate change, according to a report by The Chicago Council on Global Affairs. It further suggests that climate change threatens to undermine not only how much food can be grown but also the food's nutritional quality.
Hydraulic Fracturing Bans, Impacts Assessed
Santa Cruz became the first county in California to ban hydraulic fracturing. Meanwhile, two state Senate committees in North Carolina unanimously passed legislation lifting the state's moratorium on that oil and natural gas production technique.
The entire North Carolina Senate voted to lift the moratorium Thursday. It will now go to the House for consideration. The bill focuses on extending the deadline for development of rules for hydraulic fracturing by the Mining and Energy Commission and reduces fees for drillers.
It also requires companies to report any chemicals used in the drilling process--information the state would hold confidentially and disclose to emergency responders or health care professionals in case of emergency. But it would make unauthorized disclosure of those chemicals a misdemeanor.
A new study published in the journal Environmental Science and Technology focuses on the implications of increasing use of this production technique for the climate. It finds that natural gas can help reduce greenhouse gas (GHG) emissions but that in the absence of targeted climate policy measures it will not substantially change the course of global GHG concentrations.
"Over the range of scenarios that we examine, abundant natural gas by itself is neither a climate hero nor a climate villain," said co-author and Duke University Energy Initiative Director Richard Newell.
Design of these climate policies is as important as the abundance of natural gas. Increased supply of natural gas has the potential to decrease the cost of implementing comprehensive climate policies.
