The chances of the world holding temperature rises to 2C – the level of global warming considered "safe" by scientists – appear to be fading fast with US scientists reporting the second-greatest annual rise in CO2 emissions in 2012.
Carbon dioxide levels measured at at Mauna Loa observatory in Hawaii jumped by 2.67 parts per million (ppm) in 2012 to 395ppm, said Pieter Tans, who leads the greenhouse gas measurement team for the US National Oceanic and Atmospheric Administration (NOAA). The record was an increase of 2.93ppm in 1998.
Large rise in CO2 emissions sounds climate change alarm
Global temperature rise is fastest in at least 11,000 years, study says
Over the past century, global average temperatures appear to have risen faster than at any time since the end of the last ice age 11,300 years ago, and perhaps longer. Meanwhile, the magnitude of the increase has been unmatched in at least the past 4,000 years.
Researchers say those are the implications of a new study that uses natural stand-ins for thermometers to trace temperature trends back to the beginning of the current warm, interglacial period. Significantly, the study’s findings suggest the current warming trend cannot be explained by naturally occurring temperature variability, a lingering issue in the debate over the impact of human activity on global warming.
Ban on Radioactive Fracking Waste Passed by Putnam County, NY Legislators
A coalition of health and environmental groups gathered in Carmel, New York yesterday following the meeting of the Putnam County Board of Legislators to congratulate the legislators for voting to prohibit the sale, application and disposal of waste products in the County from natural gas drilling operations.
The new law bans the sale of fracking waste, the processing of fracking waste at County and privately operated wastewater treatment plants, and the application of fracking brine on County roads and private property including applications for de-icing and dust control purposes.
Fort Collins, Colorado bans fracking within city
The Fort Collins City Council slammed the door on fracking within city limits Tuesday and potentially opened another door to legal action. With a large crowd looking on, council members voted 5-2 on Tuesday to give final approval to an ordinance that prohibits hydraulic fracturing, or fracking, within the city.
Council members Wade Troxell and Aislinn Kottwitz opposed the ordinance, which would also ban storage of materials and waste from fracking in the city.
Climate change science poised to enter nation's classrooms
New national science standards that make the teaching of global warming part of the public school curriculum are slated to be released this month, potentially ending an era in which climate skepticism has been allowed to seep into the nation's classrooms.
The Next Generation Science Standards were developed by the National Research Council, the National Science Teachers Association, the American Association for the Advancement of Science, the nonprofit Achieve and more than two dozen states.
Railroads emerge as alternative to Keystone XL pipeline for moving oil sands from Canada
Even if foes of the Keystone XL pipeline block it, companies seeking to get Canada’s oil sands to U.S. and world markets could travel the old-fashioned way: by rail.
While TransCanada has been trying to obtain a U.S. permit to build the 875-mile northern leg of its Keystone XL pipeline, Canadian and U.S. railroad companies have been busy installing new track and loading facilities to carry the oil sands crude from northern Alberta to refineries in the United States and Canada.
Keystone XL pipeline report slammed by activists and scientists
Green activists and climate change scientists have slammed a new report from the Obama administration that raises no serious objections to building a massive and controversial oil pipeline.
The Sierra Club, one of the US's oldest and most respected environmental advocacy groups, attacked the State Department study into the proposed Keystone XL piepline – which will bring oil from Canadian tar sands deposits down to the Gulf of Mexico – as a "deeply flawed" analysis of the environmental consequences of the project.
