27 July 2017, Climate News Network, Geo-engineers propose climate compromise. Humans have unintentionally changed the world and turned up the temperature. A climate compromise might turn down the heat. Geo-engineering, the deliberate alteration of the planet to undo its inadvertent alteration by humans over the past 200 years, is back on the scientific agenda, with a climate compromise suggested as a possible solution. One group wants to turn down the global thermostat and reverse the global warming trend set in train by greenhouse gases released by fossil fuel combustion, by thinning the almost invisible cirrus clouds that trap radiation and keep the planet warm. Another group proposes to inject sulphur particles into the stratosphere, and keep on doing so for 160 years, to block enough sunlight and lower the planetary temperature. And a third group wants to see a cocktail of both approaches: thin the high cirrus clouds that stop heat from escaping, and at the same pump particles into the stratosphere to scatter the incoming sunlight and limit the disadvantages of each approach by mixing them. The verb “wants” in all three studies is neither fair nor appropriate: all three groups concede that the healthy answer is for humans to fulfil the pledge made in 2015, and start to reduce fossil fuel emissions so drastically that global average temperatures stay well below the 2°C maximum rise agreed by 197 nations at the Paris climate conference.

11 July 2017, The Guardian, No wonder the government tries to hide its emissions reports. They stink. Last Friday, the Australian government finally released the latest greenhouse gas emissions report, showing emissions have risen in the past year. When excluding emissions from land use, 2016 saw Australia release a record level of CO2 into the atmosphere. It confirms the failure of the government’s environmental policy at a time when electricity prices – despite the absence of a carbon price – continue to rise at levels above inflation. The government has a history of being scared to release the greenhouse gas reports. Last year it released the March 2016 and June 2016 reports on the Thursday before Christmas – not exactly peak viewing time. It also meant the March report was released nine months after the March quarter had actually finished. And once again the government held off releasing the latest report. But in a level of coincidence equal to that of Bill Heslop running into Deirdre Chambers in the Porpoise Split Chinese restaurant, on the day that the Australian Conservation Foundation released FOI documents showing that the government had been sitting on the report for more than a month, the government released the latest report. And in an effort that rather stretches the meaning of “quarterly”, the government “incorporated” the September quarter figures into the December report. It says something about how poorly this government values the issue of climate change that over a month ago we had the figures on the entire production that occurred in Australia during the first three months of this year, and yet here we are in July and we still only know the level of greenhouse gas emissions up to December last year. The figures in the report quickly made it obvious why the government has held off releasing them. They stink. And as every report since June 2014 has shown, the end of the carbon price has led to an increase in emissions. The poor departmental officials try to paint a happy picture. The release leads with the line that “total emissions for Australia for the year to December 2016 (including Land Use, Land Use Change and Forestry) are estimated to be 543.3 Mt CO2-e.” They note that this is 2.0% below emissions in 2000, and 10.2% below emissions in 2005. Oddly, they don’t note that is it 1.0% above the emissions in 2015. The inclusion of land use, land use change and forestry is a fairly dodgy measure. Read More here
6 July 2017, Climate Home, The tax-free shipping company that took control of a country’s UN mission. How the tiny, climate-threatened Marshall Islands came to be represented at UN shipping talks by a private company based in Virginia, 11,000 km away. In 2015 Tony de Brum, then foreign minister of the Marshall Islands, came to the International Maritime Organisation (IMO) in London to deliver a simple message: international shipping must decarbonise or be responsible for destroying his country. International shipping could be responsible for nearly a fifth of the world’s carbon emissions by 2050. If the IMO, the branch of the UN that regulates international shipping, failed to set ambitious climate targets, it would be disastrous for low-lying islands like his own, de Brum would say. But when he walked in to the IMO plenary, de Brum found strangers sitting in his country’s place. “I was talking about a Goldilocks situation,” he told Climate Home two years later on the verandah of his bungalow on the Marshallese capital atoll Majuro, a few feet from the lagoon. “We had some difficulty convincing the people who were sitting in our seats, literally, that we were the representatives of the Marshall Islands.” The people de Brum found representing the Marshall Islands were from International Registries Inc. (IRI), a private shipping register headquartered in Reston, Virginia. According to its website, the company provides access to the Marshall Islands flag and a “zero tax jurisdiction that statutorily exempts non-resident domestic corporations from taxation on their income and assets”. Thanks to IRI, the Marshall Islands boasts the second largest fleet of ships in the world and the world’s largest fleet of oil tankers. The company attracts ship owners with the promise of zero corporation tax and no seafarer nationality requirements – the latter allows them to skirt organised labour. The 45,000 offshore companies registered with IRI also benefit from corporate anonymity. De Brum, now climate change ambassador for the Marshall Islands, said he was “appalled” by IRI’s suspicious response to his arrival at the IMO. He did eventually deliver his message. But two years on, the shipping industry remains out of step with the rest of the world on climate change. In 20 years, the IMO has made just one intervention to address carbon emissions: an efficiency index which the International Energy Agency said would only improve efficiency by 1% between 2015 and 2025. A new study by CE Delft found the efficiency of new ships actually got worse in 2016. Read More here
8 June 2017, The Conversation, What is a pre-industrial climate and why does it matter? Over the past few days there has been a lot of talk about the Paris climate agreement, from which the United States is planning to withdraw. Although this is a setback, there is still near-complete consensus from the world’s governments that a strong effort to tackle climate change is needed. The Paris Agreement aims to limit global warming relative to a pre-industrial baseline. Its precise commitment is: Holding the increase in the global average temperature to well below 2℃ above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5℃ above pre-industrial levels, recognising that this would significantly reduce the risks and impacts of climate change. But this begs the question: what are “pre-industrial levels”? Clearly, if we’re aiming to limit global warming to 1.5℃ or 2℃ above a certain point, we need a common understanding of what we’re working from. But the Paris Agreement doesn’t provide a definition. This becomes key as governments expect climate scientists to coherently compare different plans to reach their Paris targets. It’s crucial to be clear on what researchers mean when we say “pre-industrial”, and what assumptions our projections are based on. Of course, as the chart below shows, no matter which baseline we use it’s clear there’s been a drastic rise in global temperature over the last century. Read More here
