15 June 2015, Climate News Network, Long-lived CO2 warms world for many millennia. The heat given off by burning fossil fuels warms the Earth far less than the carbon dioxide emitted, which research shows traps the heat in the atmosphere for thousands of years. Gun the engine, and the ignition of fossil fuel produces not just working energy but heat that dissipates quickly into the atmosphere. But it also produces carbon dioxide that dissipates into the atmosphere. And in less than two months, according to new research, that pulse of carbon dioxide will have engendered more heat for the planet than the original touch of the accelerator. Xiaochun Zhang and Ken Caldeira of the Carnegie Institution at Stanford, California, in the United States report in Geophysical Research Letters that the carbon dioxide warming exceeds the heat released by a single act of oil combustion in just 45 days. Light the gas in the cooking stove and the heating cost to the planet is exceeded in 59 days. Burn a lump of coal, and the atmosphere feels the greater heat in just 34 days. And in all three cases, the pulses of carbon dioxide will go on heating the planet – and on, and on. “Ultimately, the warming induced by carbon dioxide over the many thousands of years it remains in the atmosphere would exceed warming from combustion by a factor of 100,000 or more,” said Professor Caldeira.

12 June 2015, Renew Economy, Negotiators told to hit accelerator as climate talks inch forward: Against a backdrop of real world momentum for climate action, the latest round of UN climate talks wrapped up today in Bonn, delivering some progress on the road to a meaningful climate deal in Paris but with widespread demands for negotiators to “pick up the pace” in the coming months….Pressure is now on governments to “make more rapid progress” and “make the necessary, bold decisions in the coming months that will ensure historic international action on climate change”. With business leaders, major investors, faith groups, youth networks, trade unions, and frontline communities all adding to the momentum demanding and driving the transition away from fossil fuels and towards a future powered by renewables, the message to governments is clear: “The transition to a low carbon world is speeding up. Countries can either ride that wave or be washed away by it.”… Read More
12 June 2015, The Carbon Brief, Letting the fox into the chicken coop! UN welcomes oil groups’ help to fight global warming: The UN will accept an unusual offer from six of Europe’s largest oil and gas groups to help it fight global warming as countries work on sealing a new international climate change agreement due in December. The proposal from companies including Royal Dutch Shell and Britain’s BP was “very, very welcome”, the UN’s top climate official, Christiana Figueres, told the Financial Times. Chief executives of the six companies wrote to Figueres in May saying they wanted to help countries devise a global carbon-pricing system ahead of the climate agreement. The move laid bare a transatlantic rift between some of the world’s largest energy groups, after US oil producers, Chevron and ExxonMobil, declined to join.

12 June 2015, Science Daily, Fighting climate change, with cement: The cement industry is one of the largest sources worldwide of carbon emissions, accounting for around five per cent of global emissions. New technologies being developed by the Norwegian University of Science and Technology may help substantially lower these emissions.Membrane-based technology developed at the Norwegian University of Science and Technology (NTNU) is one of four technologies that may be used in a full-scale CO2 capture project — in a cement factory. Gassnova, Norway’s state-funded effort to develop carbon capture and storage (CCS) technologies for commercial use, has identified Norcem’s cement plant in Brevik and Yara’s ammonia plant in Porsgrunn as the most promising candidates for a full-scale CCS demonstration project in Norway. The decision was submitted to Norway’s Ministry of Petroleum and Energy (OED) as part of a pre-feasibility study on 4 May. Read More here
