The concentration and the rate of carbon dioxide (CO2) levels in the atmosphere are spiking, according to new analysis from the World Meteorological Organization (WMO). Scientists believe the record levels are not only the result of emissions but also of plants and oceans' inability to absorb the excess amounts of CO2.
"We know without any doubt that our climate is changing and our weather is becoming more extreme due to human activities such as the burning of fossil fuels," said WMO Secretary-General Michel Jarraud. "Carbon dioxide remains in the atmosphere for many hundreds of years and in the ocean for even longer. Past, present and future CO2 emissions will have a cumulative impact on both global warming and ocean acidification."
The WMO study found that CO2 concentrations increased more during 2012 and 2013 than during any other year since 1984--and significantly higher than they were before the Industrial Revolution (278 parts per million in 1750 compared with 396 parts per million in 2013). Other greenhouse gases are also on the rise--methane has risen by 253 percent since the Industrial Revolution, and nitrous oxide has risen to 121 percent of pre-industrial levels.
A report by PricewaterhouseCoopers (PwC) on how countries grow their economy while reducing their greenhouse gas emissions linked to energy concluded that the gap is widening between what the world is achieving and what it needs to do in terms of limiting global temperatures to 3.6 degrees Fahrenheit above preindustrial levels--the target agreed at the United Nations 2009 climate summit. Carbon intensity was reduced, on average, 1.2 percent from 2012 to 2013. The needed annual reduction is 6.2 percent.
The PwC report also found that places like China, Brazil, Russia, Indonesia, Mexico and Turkey are reducing their carbon intensity far better than the world's rich nations.
"What we found this year is that emerging economies have outperformed the G7 countries because their economies are growing much more rapidly than their emissions," said Jonathan Grant, PwC director of sustainability and climate change.
BP Gets U.K. Support in Court Filing
The British government, in a court filing, offered support to limit payments by BP to victims of the 2010 Deepwater Horizon oil spill, arguing that court-mandated compensation by a U.S. District Court in 2012 undermined confidence in judicial fairness. BP has spent much of this year working to convince federal courts in New Orleans that the settlement deal allowed millions in payments to go to what it says are undeserving businesses.
In its Sept. 4 filing, the British government said the prospect of payments going to people unaffected by the spill raises "grave international comity concerns."
"The lower courts' rulings have dramatically expanded [BP's] scope of liability far beyond anything that would seem to be appropriate under our shared common-law traditions or that anyone would reasonably expect," the British government wrote in an Amicus Curiae.
The brief comes on the heels of another more recent court ruling that found the company "grossly negligent" in the explosion that killed 11 men and allowed millions of barrels of oil to flow out of the Macondo oil well into the Gulf of Mexico. The ruling opened the door to new civil penalties that could amount to as much as $18 billion and that could pressure the company to sell assets from the Americas to Asia and Russia.
Regulating Emissions from the Airline Industry
As it did to implement a tailpipe rule that sets greenhouse gas emissions standards for cars and light trucks, the U.S. Environmental Protection Agency (EPA) could use an endangerment finding to regulate emissions from the airline industry.
The EPA announced plans to release an endangerment finding proposal in April 2015 that looks at whether emissions from airlines endanger public health or welfare.
"If a positive endangerment and cause or contribute findings are made, U.S./EPA is obligated under the Clean Air Act to set [greenhouse gas] emission standards for aircrafts," the EPA said. A process to finalize such a finding could take up to year.
The announcement comes as the electricity industry faces proposed regulations that would cut carbon dioxide emissions 30 percent below 2005 levels, a move that governors of 15 states recently wrote "exceeds the scope of federal law" in a letter to President Obama.
