15 May 2017, Climate Home, India and China ‘on track to exceed Paris climate pledges’. With downgraded outlooks for coal use, India and China are set to beat their pledges to the Paris climate agreement, according to an updated analysis of their climate policies. Just as coal plants are cancelled in the two largest emerging economies, in the US, the Trump administration has started to roll back regulations designed to constrict emissions. But analysis released by Climate Action Tracker (CAT) on the sidelines of a UN climate meeting in Bonn, Germany found policies in India and China would more than outweigh slower emissions reductions in the US. The growth in global emissions has stalled in recent years, thanks mainly to reduced consumption of coal in China. “This has been attributed partially to structural changes in the Chinese economy, but also a continued policy drive to reduce coal use to both combat air pollution and climate change,” said Dr Yvonne Deng, a consultant scientist at Ecofys, one of a group of organisations that contributes to the CAT project. Deng said it was unclear whether the last three years of coal data in China was “merely a pause in the steady growth, or whether this is a sign of China having reached its peak in coal consumption”. Earlier this year, China cancelled construction plans for 103 coal power stations. If it turned out to be a sustained decline, she said, the country’s annual emissions in 2030 could be 1-2 gigatonnes lower than CAT predicted at this time last year. China’s current emissions are between 11 and 12Gt a year. Read More here

29 March 2017, The Conversation, Hazelwood closure: what it means for electricity prices and blackouts. Victoria’s Hazelwood power station will be shut down this week after nearly 50 years of supplying electricity. The imminent closure has led to concerns about blackouts, raised most recently by Deputy Prime Minister Barnaby Joyce, and rising electricity prices. So what does the evidence suggest? Blackouts ahead? Last week The Age reported that Victoria is facing “72 days of possible power supply shortfalls over the next two years”. While that sounds bad, it does not mean the state is facing imminent blackouts. This was based on a report from the Australian Energy Market Operator (AEMO), which is in charge of making sure that Australia’s energy markets work. Every week, AEMO produces something called the Medium Term Projected Assessment of System Adequacy. This report assesses the expected supply and demand of electricity for the next two years. In a recent report, AEMO did indeed forecast a “reserve shortfall” for 72 days in Victoria in the coming two years. AEMO has actually been forecasting many days of reserve shortfall, since early November last year when Engie announced the closure of Hazelwood. AEMO has also been forecasting an even greater number of days of reserve shortfalls in South Australia for well over a year. The shortfall forecast is based on a combination of factors. This includes the amount of local energy supply, the import and export of electricity from other states, the maximum daily demand for electricity, and the “reserve requirement”. The reserve requirement is essentially “spare” capacity that can be used to maintain a reliable supply if something goes wrong. If there is not enough supply to meet this requirement, there is a reserve shortfall. Forecasting maximum demand is incredibly challenging and uncertain. AEMO does it by using probabilities. This gives us a measure of the probability of a particular demand forecast being exceeded in a year. For example, a 10% chance would be expected to be exceeded one year in ten. A 50% chance would be expected to be exceeded one year in two. To illustrate the point, AEMO forecast that demand over the past summer in Victoria had a 10% chance of exceeding 9,900 megawatts. In reality, the maximum demand was only 8,747MW. That’s not to say the forecast was wrong, but rather that it was not an exceptional (one year in ten) summer. Read More here
28 March 2017, Climate Central, Trump Moves to Dismantle U.S. Climate Rules. President Trump signed a sweeping executive order Tuesday rescinding numerous federal climate policies and calling for the review and replacement of the Obama administration’s most ambitious effort to control climate pollution — the Clean Power Plan. The order is Trump’s most aggressive move yet to dismantle federal climate regulations even as established climate science shows that man-made global warming is a growing threat to human life and the economy. In all, Trump’s executive order targets at least 23 federal rules, regulations, executive orders, memorandums and reports related to energy and climate change, many of which are likely to be tied up in years of legal wrangling before being decided. The total number is likely much higher because the order directs federal agencies to tally up all their rules and regulations that can be interpreted to “constrain” energy production and prepare them to be rescinded if they’re deemed to be a “burden” on energy production and use. Legal experts and climate scientists say the move abdicates U.S. leadership on climate change and incentivizes nearly unfettered fossil fuels development across the country. Those steps could diminish the chances that countries can prevent the world from warming to levels that scientists consider dangerous — 2°C (3.6°F). ….The details of Tuesday’s executive order show the breadth of the Trump administration’s desire to dispense with existing U.S. climate and energy policy.

23 March 2017, Independent, If you really care about climate change, you should boycott the ridiculous Earth Hour stunt. The people who are wrecking the planet are the fossil fuel companies, not Georgina from Enfield who occasionally leaves the kitchen light on all night. I am an environmentalist. For my whole adult life I have protested, campaigned, helped to elect climate-savvy politicians and worked hard on what I see as the cause of my life: putting a stop to the dangerous change to our climate that is killing millions. And yet I hate one of the world’s most prominent environmental events with the intense heat of a burning climate – the annual WWF event “Earth Hour”, which this year will take place on 25 March. The charity expects millions of people around the world to symbolically switch off their lights for an hour. Earth Hour is terrible, and not just because the symbolism of darkness is very poorly thought out. The worst thing about Earth Hour is that it tricks people into thinking they’ve done something useful by turning off the lights for 60 minutes, and lets the real villains in the climate change story off the hook. By focusing on individual behaviour, Earth Hour sends out the message that ordinary citizens are the ones to blame for climate change. It passes on the unhelpful message that all we need to do is change our lightbulbs and do more recycling and everything will be fine. Every time someone says that environmentalists are nagging busybodies obsessed with making you turn your TV off standby before you go to bed, Earth Hour has contributed to that. Read More here
