14 March 2016, The Guardian, February breaks global temperature records by ‘shocking’ amount Warnings of climate emergency after surface temperatures 1.35C warmer than average temperature for the month. February smashed a century of global temperature records by “stunning” margin, according to data released by NASA. The unprecedented leap led scientists, usually wary of highlighting a single month’s temperature, to label the new record a “shocker” and warn of a “climate emergency”. The NASA data shows the average global surface temperature in February was 1.35C warmer than the average temperature for the month between 1951-1980, a far bigger margin than ever seen before. The previous record, set just one month earlier in January, was 1.15C above the long-term average for that month. “Nasa dropped a bombshell of a climate report,” said Jeff Masters and Bob Henson, who analysed the data on the Weather Underground website. “February dispensed with the one-month-old record by a full 0.21C – an extraordinary margin to beat a monthly world temperature record by.” “This result is a true shocker, and yet another reminder of the incessant long-term rise in global temperature resulting from human-produced greenhouse gases,” said Masters and Henson. “We are now hurtling at a frightening pace toward the globally agreed maximum of 2C warming over pre-industrial levels.” Read More here

11 March 2016, Washington Post, United Airlines is flying on biofuels. Here’s why that’s a really big deal. On Friday, United Airlines will launch a new initiative that uses biofuel to help power flights running between Los Angeles and San Francisco, with eventual plans to expand to all flights operating out of LAX. It’s the first time an American airline will begin using renewable fuel for regular commercial operations, and the occasion is part of a bigger movement when it comes to clean transportation in the U.S. The renewable fuel used to power United’s planes will be coming from a Los Angeles refinery operated by AltAir Fuels, which is using the facility to produce both renewable jet fuel and diesel fuel using a technology developed by Honeywell UOP, a major supplier and technology licenser in the petroleum industry. Back in 2013, AltAir and United announced their partnership, in which United will purchase up to 15 million gallons of biofuel over a three-year period. Friday’s launch will be the first application of that agreement. The flights will use a mixture of 30 percent biofuel and 70 percent traditional fuel, and United says that the biofuel will help reduce greenhouse gas emissions by about 60 percent compared with regular fuel. In general, the idea behind renewable fuels is to use a biological source — for example, plant or animal matter — rather than a geological one, like oil. The Honeywell UOP technology that’s being applied at the AltAir refinery can utilize a range of difference sources, from used cooking oil to algae. The technology has been in the works since 2007, when the company was awarded a grant from DARPA to develop green jet fuel, according to Veronica May, vice president and general manager of renewable energy and chemicals at Honeywell UOP. Currently, its technology allows for the production of diesel fuel that can be used in any proportion with existing diesel engines — up to 100 percent. Its jet fuel can replace up to 50 percent of petroleum fuel in existing aircraft. Altogether, both fuels can offer up to about an 80 percent reduction in greenhouse gas emissions compared with traditional fuel, the company says. Read More here
10 March 2016, The Guardian, Dangerous global warming will happen sooner than thought – study. Australian researchers say a global tracker monitoring energy use per person points to 2C warming by 2030. The world is on track to reach dangerous levels of global warming much sooner than expected, according to new Australian research that highlights the alarming implications of rising energy demand. University of Queensland and Griffith University researchers have developed a “global energy tracker” which predicts average world temperatures could climb 1.5C above pre-industrial levels by 2020. That forecast, based on new modelling using long-term average projections on economic growth, population growth and energy use per person, points to a 2C rise by 2030. The UN conference on climate change in Paris last year agreed to a 1.5C rise as the preferred limit to protect vulnerable island states, and a 2C rise as the absolute limit. The new modelling is the brainchild of Ben Hankamer from UQ’s institute for molecular bioscience and Liam Wagner from Griffith University’s department of accounting, finance and economics, whose work was published in the journal Plos One on Thursday. It is the first model to include energy use per person – which has more than doubled since 1950 – alongside economic and population growth as a way of predicting carbon emissions and corresponding temperature increases. The researchers said the earlier than expected advance of global warming revealed by their modelling added a new found urgency to the switch from fossil fuels to renewables. Read More here
10 March 2016, Climate News Network, Antarctic techno-fix cannot slow rising seas. Pumping seawater onto the Antarctic landmass to form ice and stop sea levels rising stands little chance of success, scientists say. Sea level rise is likely to be a problem too big to handle. Geoengineers will not be able to magic away the rising tides, according to new research. In particular, they will not be able to pump water from the sea and store it as ice on the continent of Antarctica. That is because, unless they pump it enormous distances, that will only accelerate the flow of the glaciers and it will all end up back in the sea again, a study in the journal Earth System Dynamics says. Geoengineering is sometimes produced as the high-technology solution to the environmental problems of climate change: if humans don’t change their ways and start reducing greenhouse gas emissions, say the proponents of technofix, human ingenuity will no doubt devise a different answer. But, repeatedly, closer examination has made such solutions ever less plausible. Scientists have dismissed the idea that the melting of the Arctic can be reversed, have only tentatively conceded that technology could dampen the force of a hurricane, and have found that – instead of cooling the Earth – attempts to control climate change could either make things worse or seriously disrupt rainfall patterns. On balance, scientists believe that most of the big geo-engineering ideas won’t work. Deep freeze And now a team from the Potsdam Institute for Climate Impact Research has poured cold water on the idea of pouring cold water onto the ice cap. The idea is a simple one. Are sea levels rising 3mm a year because the world is warming? Then pump the sea high onto the Antarctic landmass where it will freeze and stay frozen for a millennium. But to be sure of that, say the Potsdam team, at least 80% of the water would have to be pumped 700 km inland. That would take more than 7% of the annual global primary energy supply just to balance the current rate of sea level rise.But even in a world recently committed to a warming of less than 2°C, the seas are going to go on rising. Sea levels could rise at least 40cms by the end of the century – or possibly 130cms, with devastating consequences for low-lying coastlines: rich megacities might be able to build defences, but the poorest communities would be swept away.
