Is a 1.5°C climate change target still achievable?

While we ponder whether we will overshoot the already dangerous level of 2 Degrees Celsius of warming on the way to 4C or 5C degrees warming by the end of the century, scientists have assessed whether it is still possible to restrict global warming to just 1.5C degrees. The short answer? Yes, it is technologically possible, but requires substantial and immediate emissions reductions with no room for further delay or obstruction.

The new study by researchers at the International Institute for Applied Systems Analysis (IIASA) and Potsdam Institute for Climate Impact Research (PIK) was published in Nature Climate Change examines scenarios for the energy, economy, and environment that are consistent with limiting climate change to 1.5 degrees Celsius above pre-industrial levels, and compares them to scenarios for limiting climate change to 2 degrees Celsius.

“Actions for returning global warming to below 1.5 degrees Celsius by 2100 are in many ways similar to those limiting warming to below 2 degrees Celsius,” says IIASA researcher Joeri Rogelj, one of the lead authors of the study. “However, the more ambitious 1.5 degrees Celsius goal leaves no space to further delay global mitigation action and emission reductions need to scale up swiftly in the next decades.”

More than 100 nations support the goal of limiting warming to 1.5C degrees - that is over two thirds of UNFCCC nation signatories. Understandably, the Alliance of Small Island States (AOSIS) are particularly vocal for this limit. Many of the small low lying island nations will not survive the impacts of sea level rise with the higher target. They are supported by the Least-Developed Countries (LDCs) block.

PriceWaterHouseCoopers analysis of comparative ambition for Australia and Canada

An analysis published 11 May 2015 by PriceWaterhouseCoopers estimated the target that Japan, Canada and Australia needed to meet to achieve the same level of ambition as Europe or USA. We know these countries still aren't doing enough to achieve 2C target, yet they still set a benchmark for other industrial countries to also match. The EU committed to a 40% reduction on 1990 levels by 2030 and the US a 26-28% reduction on 2005 levels by 2025.

Applying the Low Carbon Economy Index (LCEI) model to match the present US target PricewaterhouseCoopers results came up with:

  • Japan: 6% reduction on 2005 levels by 2025
  • Canada: 19% reduction on 2005 levels by 2025
  • Australia: 24% reduction on 2005 levels by 2025

"Our LCEI report in 2014 showed that global carbon intensity is falling by around 1% per year, but that this needs to be 6% per year on average to stay within the 2 degrees carbon budget. All these targets fall well short of the 2 degrees goal." reports PriceWaterhouseCoopers.

Shell Arctic oil drilling rigs unwelcome in Seattle

Over the last week Royal Dutch Shell has faced stiff public opposition in Seattle to it's Arctic oil exploration program with the arrival of the Noble Explorer and Polar Pioneer drill rigs for maintenance and provisioning in Seattle.

The Noble Discoverer arrived in the Port of Everett last Tuesday (12 May). It was met by half a dozen kayaktivists with a sign that said "Shell No".

Last week protesters at the Port of Seattle setup a tripod at Terminal 5 to voice their opposition to the Polar Pioneer drill ship, which had been parked at Port Angeles but arrived in Seattle on Thursday. A handful of kayaktivists met the Polar Pioneer on the waters of Elliot Bay on Thursday when it arrived.

On May 12 Rising Tide Seattle said in a tweet that "This morning work stopped at Shell's Seattle Operations for nearly 3 hours - more coming this week!" A tripod was setup at the main entrance during the morning and a statement read out. Watch on Youtube

Shell wants to use the Port of Seattle as it's base to refuel, re-provision and carry out maintenance on it's Arctic drill rigs. But even the Seattle City Council has declared it's opposition to Shell's plans.

Shell Polar Pioneer Arctic drilling rig blockaded at Port Terminal 5 in Seattle

On Monday 18 May 2015, over five hundred people blockaded Port of Seattle Terminal 5 where Royal Dutch Shell's Polar Pioneer oil rig is docked.

Shell is planning to do exploratory oil drilling in the Chukchi Sea in the Arctic off the Alaska coast despite climate scientists saying we cannot afford to drill for oil in the Arctic for a safe climate and the environmental risks dangers if a major oil spill were to occurr in the Arctic.

In December 2012 it's oil drilling rig Kulluk ran aground off Kodiak Island while it was being moved from Alaska to Washington State to avoid paying $6 million in taxes.

Protestors started gathering before 7am before marching to blockade the terminal front gate. Here is how the day unfolded. There is a great live ustream video report from KPFA community powered radio from Berkeley California.

Central England record warmth in 2014 attributed to climate change

In 2014 Central England recorded it's hottest year dating back to 1659, when the instrumental temperature record started.

A new study has found that the record high Central England temperatures can be attributed to anthropogenic influences with 90 per cent confidence. The syudy highlighted that the chances of record warm years in Central England has increased by at least 13-fold.

"This study points to a large influence of human activities on extreme warm years despite the small region of study and the variable climate of Central England. Our analysis shows that climate change is clearly visible on the local-scale in this case." said the study abstract.

The researchers used two methodologies: one based on climate model simulation, and another based on the observational record. They found agreement in the results between the two methodologies strong, "A substantial increase in the likelihood of warm years due to anthropogenic influences is found using both methods with very high confidence. This conclusion is robust especially when we consider that the two methods are primarily based on different datasets, one model simulations and the other observations."

The study is a growing body of scientific work in Fractional Attribution of Risk (FAR), whereby climate events are assessed as to their probability of being influenced by anthropogenic climate change.

Alcoa #Anglesea power station to close, First Victorian #coal domino falls

Published as an original article at

While renewables are being encouraged by the Andrews Government with the proposal for a Victorian Renewable Energy Target, the first domino in Victoria's brown coal fired power industry has succumbed.

Alcoa announced this week it would be closing it's 50MW high sulphur dioxide polluting coal fired power station and mine at Anglesea at the end of August, 2015. Since the Alcoa Port Henry Aluminium Smelter closed in 2014, which used all the power generated and more, this power station has been targeted for closure by the local community in particular the Surf Coast Air Action group, saying the social licence and justification has ended.

SCAA spokesperson Andrew Laird said in a media release, "This is a great outcome for the Anglesea community and for clean air in Australia. It also shows that coal impacted communities can achieve big things when they work together. While we are delighted that the redundant facility will finally close we are also very mindful about the remaining workers and call upon Alcoa to make sure that those who don't wish to take a redundancy package are deployed onto the massive rehabilitation task.”

Victorian Renewable Energy Target proposed as Minister challenges Federal Government to get out of the way

Published as an original article at

On Thursday Victorian Energy Minister Lily D'Ambrosio told the Federal Government that Victoria wants to establish it's own Victorian Renewable Energy Target (VRET) and to get out of the way and clear the federal legislative path to do so.

In 2009 the States and Territories negotiated the closure of their own state based RET schemes on the condition of the adoption of the present federal scheme of 41,000GWh of renewable energy. The Federal Government negotiating a much lower target of 33,000GWh of power is an abrogation of the deal done by the States and Territories with the Rudd Federal Government in 2009.

Victoria can't just proceed with a new VRET scheme as the Federal Government needs to remove section 7c from the Renewable Energy (Electricity) Act 2000 (Cth), which prevents State Governments from having their own schemes similar to the Renewable Energy Target (RET).

“The Federal Government must move out of Victoria’s way and change the law. Our state needs a proper renewable energy target, to support the industry and reduce pollution.” said Lily D'Ambrosio.

Pope Francis and UN Secretary General Ban Ki-Moon on the moral imperative of climate action

Catholic church statements on climate change are undermining the moral authority of catholic Prime Minister Tony Abbott and his government's poor record on climate action and support for fossil fuels and expansion of coal.

Tony Abbott's 'coal for prosperity' statement is looking more ridiculous and out of step with every passing moment.

Our Prime Minister was closely asociated with Cardinal Pell, a strong climate denier in the Australian Catholic Church. (See Graham Readfearn: Cardinal Pell’s mine of climate misinformation) Unfortunately Pell's climate ideas are not widely held in the upper echelon of the Catholic church.

With the Paris climate talks approaching in December, 2015, Pope Francis has indicated that a papal encyclical on the environment and climate change is being prepared for issue. This will lay the moral ground and support for progress at the UN climate talks, according to Neil Ormerod, Professor of Theology at Australian Catholic University, writing in The Age in Januray, 2015.

Tesla Battery launch a revolutionary #energy solution for #climate

This article was originally published at San Fransisco Bay Area Indymedia and at

In a remarkable 20 minute presentation on Thursday night, Elon Musk, the billionaire founder of Paypal and Tesla Motors, launched a scalable battery storage system aimed at multiple markets: from personal home use, small business to utility scale electricity storage.

It is the missing jigsaw piece to the solar and renewables revolution already under way in replacing fossil fuel power generation. Elon Musk outlined the critical problem of climate change and greenhouse gas emissions from an ageing fossil fuel infrastructure, explained how it can be addressed, and launched an innovative product that could plausibly make a substantial contribution as a solution.

One of the traditional arguments against a high level of renewables in our electricity grid has been the need for constant baseload power that needs to be provided by coal, gas peaking turbines, or nuclear. This argument was always false, as several reports have shown (Rocky Mountains Institute at Clean Technica, Mark Diesendorf at The Conversation, Dr David Mills at ABC Science), but nevertheless it provided a powerful, if faulty argument for maintaining our aging fossil fuel generation capacity.

Our energy grid is built upon generating power constantly to meet the demand at any particular point in time. Variable sources of energy such as wind and solar have been steadily growing as a proportion of grid supply, but studies have shown that network demand has a lot of natural variability anyway. Both wind and solar generation are able to be forecast over short day-length or so periods, and thus managed as part of the normal regulation of grid demand and response. Relatively cheap energy storage will enable some fine network adjustment to power output, while aiding in decentralisation of power generation and storage. It adds a missing piece of the puzzle which aids in transitioning to a 100 per cent renewables energy system.

California adopts 40 per cent emissions reduction target below 1990 levels by 2030

Awesome news from California: Governor Brown announced a major greenhouse gas reduction target of 40 per cent reduction on 1990 levels by 2030. This matches Europe's commitment.

California is the largest economy in North America and the 7th largest economy globally. It is a significant announcemewnt and goes much deeper than President Obama's national target of a 26-28% emissions reduction on 2005 levels by 2025.

"With this order, California sets a very high bar for itself and other states and nations, but it's one that must be reached - for this generation and generations to come," said Governor Brown.

The long term target is reducing emissions 80 percent under 1990 levels by 2050.

The order also includes instructions for maintaining and updating the state's climate adaptation strategy, Safeguarding California, and ensure that its provisions are fully implemented. Climate change impacts and predictions will also feature in State Agency planning and investment decisions and full life-cycle cost accounting, and Infrastructure planning.

In January 2015 at his inauguration Governor Jerry Brown announced that Climate Change action would be prominent for his next 4 years of his administration. With California already on track to meet it's target of a third of electricity from renewable sources by 2020. Brown announced that this should increase to 50 per cent of electricity generation by 2030, plus a 50 per cent reduction in petroleum use in cars and trucks, and to double the efficiency of existing buildings, and use cleaner heating fuels.

But it is not all smooth sailing as his administration has come in for criticism over support for fracking, and the continued allocation of water during the 4 year long drought for fracking.

"Gov. Jerry Brown deserves credit for this important step toward fighting global warming, but the governor continues to undermine his own plans by backing fracking,” said Kassie Siegel of the Center for Biological Diversity’s Climate Law Institute media release. “Fracking pollution threatens to blow a huge hole in California’s target for reducing planet-warming emissions. No plan to prevent climate disruption can succeed if it doesn’t include a rapid transition away from fracking and other dangerous oil and gas production."
