30 October 2015, Renew Economy, With latest fires crisis, Indonesia surpasses Russia as world’s fourth-largest emitter. New analysis reveals even more troubling news about Indonesia’s fires crisis. Emissions from this year’s fires have reached 1.62 billion metric tons of CO2—bumping Indonesia from the sixth-largest emitter in the world up to the fourth-largest in just six weeks. The analysis from Guido van der Werf with the Global Fire Emissions Database also reveals that:

  • Emissions from Indonesia’s fires alone are approaching the total annual emissions of Brazil.
  • Indonesia’s current total emissions hover around 760 Mt CO2 (excluding land-use change), meaning the fires alone have tripled Indonesia’s entire annual emissions.
  • Indonesian fires during 38 of the past 56 days (as of October 26) have released more greenhouse gas emissions than the entire U.S. economy on those days.

While the country may finally be getting some relief as heavy rainfall interruptsmonths of record-breaking fires and toxic smog in South Sumatra and Kalimantan, the damage to human health, the economy and the global climate has already been done. Read More here

29 October 2015, Yale Connections, Long-Term Drought Impacts on Trees. Scientists find that droughts harm trees for longer than previously understood. ANDEREGG: “We’ve known for decades that drought has harmful effects on trees. That during drought they grow slower and they have a higher chance of death.” That’s William Anderegg, a biologist at the University of Utah. He says until recently, researchers were not clear about what happened to the trees after a drought ended. So his team looked at the growth of trees after severe drought in more than a thousand forests across North America, Europe, and Asia. They found that even four years after a drought, trees continued to grow more slowly than normal. ANDEREGG: “Trees take up about a quarter of human emissions of CO2 each year, and that’s a very big slowing effect on climate change. So if droughts cause forests to take up less carbon, that could very much speed up the pace and the severity of climate change.” Anderegg says it is too early to know what the long-term implications will be. ANDEREGG: “Some of our best models suggest that forests could be relatively resilient and others suggest they could really die off en masse and lose a lot of their carbon to the atmosphere. And we don’t know which of those is more likely.” But Anderegg says that the future of the world’s forests is still in our hands. ANDEREGG: “I always like to emphasize that a lot of that future does depend on human decisions and what we do about climate change.” Read More here

28 October 2015, Climate News Network, Rise in wildfires depletes forests’ carbon store. As the world warms, the increasing hazard of forest fires is dangerously tilting trees’ carbon storage balance from positive to negative in some regions of Alaska. In a warming world, forest fires could be about to put more carbon dioxide into the atmosphere than the trees absorb. New research by US scientists looked at decades of wildfire incidence in Alaska, and they have found that at least one region is now a net exporter of carbon. This is a reversal of the normal arrangements, whereby trees photosynthesise tissue from the carbon dioxide in the atmosphere. As they absorb carbon, they sequester it in roots, timber and leaves, and then in leaf litter in the forest soils. Fire is a natural hazard, and some geographical zones –the Mediterranean, the US southwest, and Australia – are adapted to periodic fire. But as the planet warms, there have been increasing levels of fire even in therainforests of the Amazon and in the boreal forests of the near-Arctic.

28 October 2015, The guardian, Paris climate deal will not include global carbon price, says UN climate chief. Christiana Figueres tells investor event that a climate deal to be agreed in Paris in December will not be able to come up with a global carbon price. A climate change deal to be agreed in Paris in December will not be able to come up with a global carbon price, the United Nations’ climate chief, Christiana Figueres, said on Tuesday. Big multinational companies and investors, and most recently oil majors, have called for a global carbon price to help spur investments in low-carbon energy. A global carbon price would help to create an incentive for operators of power plants and factories to switch to cleaner fuels such as gas or to buy more energy-efficient equipment. When the European Union launched a carbon trading scheme in 2005 there were expectations this would eventually lead to a global carbon scheme by 2020 worth around $2 trillion. But the difficulties of bringing together different carbon schemes from countries around the world means the goal of a global carbon price remains elusive.
