The Local Election That Could Determine the Future of American Coal

A poll released in mid-September by the Power Past Coal coalition found that Washington state voters opposed transporting coal for export through their state 51 percent to 37 percent.  Oregon voters opposed the plans by 54 percent to 39 percent.  In both states sentiment in opposition has grown in the last year.

As opposition grows and the market value of coal declines, plans for three more Pacific Northwest export terminals have been scrapped by developers in the past year.

The success or failure of one of the two remaining Washington terminal plans, the Gateway Pacific Terminal at Cherry Point outside of Bellingham — not far from the Canadian border and San Juan Islands — could be determined much sooner than the proposed Millennium Bulk Terminals here in Longview on the Columbia River north of Portland, Oregon.

UCLA chemical engineering researchers have created a new synthetic metabolic pathway for breaking down glucose that could lead to a 50 percent increase in the production of biofuels.

Glycolysis is currently used in biorefinies to convert sugars derived from plant biomass into biofuels, but the loss of two carbon atoms for every six that are input is seen as a major gap in the efficiency of the process.  The UCLA research team's synthetic glycolytic pathway converts all six glucose carbon atoms into three molecules of acetyl-CoA without losing any as carbon dioxide.

Secretary of State Kerry and Senator Boxer Remark on the IPCC Report

Secretary of State John Kerry:

This is yet another wakeup call:  Those who deny the science or choose excuses over action are playing with fire.

Once again, the science grows clearer, the case grows more compelling, and the costs of inaction grow beyond anything that anyone with conscience or common sense should be willing to even contemplate. ...

The United States is deeply committed to leading on climate change.  We will work with our partners around the world through ambitious actions to reduce emissions, transform our energy economy, and help the most vulnerable cope with the effects of climate change.


We do so because this is science, these are facts, and action is our only option.

Melting Arctic Permafrost Looms as Major Factor in Warming, Climate Change

Credit: Penn State Institutes of Energy and the Environment
A heavyweight boxer in the climate change match is missing from the fifth climate assessment report released by the Intergovernmental Panel on Climate Change (IPCC) on Friday.

Permafrost, which is frozen ground that doesn't melt during the summer, covers 24 percent of the land in the northern hemisphere.  It also stores approximately 1.5 trillion tons of carbon – twice the amount of carbon currently in the atmosphere.

When the organic matter that makes up permafrost thaws, the carbon it contains becomes exposed to the elements, which can escape into the air in the form of heat-trapping gases with the potential to knock out efforts to slow down global warming with a one-two punch.

A Carbon Limit

The United Nations Intergovernmental Panel on Climate Change released a report this week making concrete the threat and challenge humankind faces in responding to the reality of climate change.

For the first time the panel described an upper limit for carbon dioxide in the atmosphere to avoid the most dangerous effects of climate change.  To keep temperatures from rising more than 3.6 degrees Fahrenheit (2 degrees Celsius), no more than 1 trillion tons of carbon can be burned.  Since the dawn of the industrial age, we have already burned about half of that total. The report estimated that there are more than 3 trillion tons of carbon in the form of fossil fuels remaining in the world.

This finding underscores a point increasingly stressed by climate change activists — that from now on we must find a way to leave in the ground a large portion of the carbon available to us.

Cooling from human aerosol emissions offsets about one-third of the warming from human greenhouse gas emissions. The new IPCC statement says that even taking that aerosol cooling effect into account, humans are still the main cause of the global warming over the past 60 years.

What's not causing global warming:  natural external factors like solar activity, and natural internal factors like ocean cycles:
The contribution from natural forcings is likely to be in the range of -0.1°C to 0.1°C, and from internal variability is likely to be in the range of -0.1°C to 0.1°C.

Alarming IPCC Prognosis: 9°F Warming for U.S., Faster Sea Rise, More Extreme Weather, Permafrost Collapse — by Joe Romm

Humanity's choice (via IPCC): Aggressive climate action ASAP (left figure) minimizes future warming. Continued inaction (right figure) results in catastrophic levels of warming, 9°F over much of U.S.The UN Intergovernmental Panel on Climate Change (IPCC) now says we are as certain that humans are dramatically changing the planet’s climate as we are that smoking causes cancer.

So perhaps the best way to think about the IPCC, which has issued a summary of its latest report reviewing the state of climate science, is as a super-cautious team of brilliant diagnosticians and specialists (who, like many doctors, aren’t the best communicators).

The diagnosis is that humans are suffering from a fever (and related symptoms) caused by our own actions — primarily emissions of carbon pollution.  Indeed, team IPCC is more certain than the last time we came in 6 years ago and ignored their advice.  They are 95% to 100% certain we are responsible for most of the added fever since 1950. They explain:

The best estimate of the human-induced contribution to warming is similar to the observed warming over this period.
To clarify the diagnosis, the best estimate is that humans are responsible for all of the warming we have suffered since 1950.

Emissions from livestock can be cut by 30 percent just by adopting better farming practices, according to a new report by the U.N.

The report, published Thursday by the U.N. Food and Agriculture Organization, found that using better, more easily-digestible feeds can reduce the amount of methane generated by ruminants like cows, and that better breeding techniques and maintenance of animals’ health can also reduce the numbers of unproductive animals in a herd. In addition, better soil management on grazing lands can increase the pasture’s ability to act as a carbon sink.

The quest to harness hydrogen as the clean-burning fuel of the future demands the perfect catalysts--nanoscale machines that enhance chemical reactions.  Scientists must tweak atomic structures to achieve an optimum balance of reactivity, durability, and industrial-scale synthesis.  In an emerging catalysis frontier, scientists also seek nanoparticles tolerant to carbon monoxide, a poisoning impurity in hydrogen derived from natural gas.  This impure fuel--40 percent less expensive than the pure hydrogen produced from water--remains largely untapped.

Now, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have created a high-performing nanocatalyst that meets all these demands.  The novel core-shell structure--ruthenium coated with platinum--resists damage from carbon monoxide as it drives the energetic reactions central to electric vehicle fuel cells and similar technologies.

Gina McCarthy, administrator of the U.S. Environmental Protection Agency, announced Friday that the government will for the first time begin regulating carbon dioxide emissions from new coal- and natural gas-fired power plants under the Clean Air Act.  Speaking in Washington, McCarthy said, “Climate change is real, human activities are fueling that change, and we must take action to avoid the most devastating consequences.”

The EPA regulations, which the coal industry vows to challenge in court, will require new coal plants to emit fewer than 1,100 pounds of carbon dioxide per megawatt hour, considerably lower than the average 1,800 pounds of CO2 per megawatt hour currently produced by coal-fired power plants.  Such limits would require the new plants to deploy carbon capture and storage (CCS) technology, which has not been used on a wide scale.

Cost of Solar Power 60% Lower than Early 2011 in US

Solar panel costs are partly down due to technological and manufacturing advancements. However, the main driver of the reduction in installed solar panel costs is most likely just economies of scale (as more solar panels are produced, costs come down) and market maturation (as the market grows, competition grows — driving down the price of solar — and installers achieve economies of scale and cut their prices).

Naturally, as solar panel costs continue to drop, solar power grows even faster, which further brings down the cost of solar. (Thankfully, this is quite different from the situation with non-renewable fossil fuels, where greater use of fuel shortens supply and drives costs up over time.)

Storing carbon dioxide in the same shale formations that produce natural gas may be an effective way to sequester carbon dioxide produced by fossil fuel-burning power plants, according to a U.S. study. Computer models by researchers at the University of Virginia suggest the Marcellus Shale, a 600-square-mile formation in the northeastern U.S. that is a center of hydrofracturing natural gas, is capable of storing half the CO2 emitted by U.S. coal plants from now to 2030.

One advantage of using fracked shale formations for carbon storage is that it would not require building new infrastructure to sequester the CO2.

A question that needs to be answered is whether the stored carbon, injected in the wells in liquid form, would migrate back toward the surface in fracked shale formations.

MIT researchers have found a new family of materials that provides the best-ever performance in a reaction called oxygen evolution, a key requirement for energy storage and delivery systems such as advanced fuel cells and lithium-air batteries.

Splitting water into its constituent elements could be a significant boon for renewable energy sources, such as wind and solar, whose output is highly variable. Using a catalytic system, electricity from a solar panel or wind turbine can be fed into a container of water, and the streams of oxygen and hydrogen produced by splitting the water molecules can be collected in separate tanks.  Then, when the power is needed, the two gases can be recombined, such as in a fuel cell, to produce water and electricity.

This method is well understood in principle, but to make it economically viable, researchers must find catalysts that are inexpensive, easily manufactured and efficient enough to carry out the conversion without losing too much of the original power.  The new finding could be a significant step in that direction, the MIT researchers say.

Eagerly Awaited Methane Study Offers Answers in Wider Debate

Scientists and policymakers have worried that shale gas sites in the United States are leaking record amounts of methane, a potent greenhouse gas, from wellheads, pipelines, valves and other paraphernalia. A new study suggests some of the major leaks have been plugged, while other leaks remain a problem for policymakers to tackle.

Cornell University civil and environmental engineering professor Anthony Ingraffea, who co-authored a 2011 study showing that the climate footprint of the methane emissions from natural gas production is higher than previously estimated, said Allen’s study shows that methane emissions can be contained if energy companies choose to install the right equipment.

In a collective act of media irresponsibility, The New York Times and The Washington Post have joined The Wall Street Journal in publishing “don’t worry, be happy” articles days before the big UN climate science report will say quite the opposite.

The Scottish government said on Monday it has given consent on for work to begin on the largest tidal energy project in Europe in Pentland Firth, which separates the Orkney Islands from mainland Scotland.

"When fully operational, the 86 megawatt array could generate enough electricity to power the equivalent of 42,000 homes - around 40 per cent of homes in the Highlands," said Fergus Ewing, Scotland's energy minister.

"This exciting development in the waters around Orkney is just the first phase for a site that could eventually yield up to 398 MW," he added.

The second quarter of 2013 was photovoltaic solar power’s second-best ever, with 832 megawatts of capacity installed between April and June.  The Q2 2013 numbers, compiled by the quarterly U.S. Solar Market Insight Report — courtesy of GTM Research and the Solar Energy Industries Association — show a steady upward trend in the use of photovoltaic (PV) solar despite the ups and downs of the market and government policy.

California Governor Edmund G. Brown Jr. and China’s top climate official, National Development and Reform Commission (NDRC) Vice Chairman Xie Zhenhua, signed an agreement on climate change—the first between the NDRC and a subnational entity. The NDRC oversees China’s efforts to address climate change and much of the government’s economic strategy.

With global efforts to reduce carbon dioxide emissions stalled, cutting short-lived climate pollutants has emerged as an unsung story of U.S.-led progress in the international climate arena.

Momentum has quietly been building toward a series of agreements that, when combined, could make a significant dent in the amount of manmade warming that occurs during the next several decades.

Global Warming's Missing Heat:  Look Back in Anger (and Considerable Disbelief)

Probably the most frustrating argument on climate science in the public discourse is about the hiatus in surface temperature rise, and the failure of the models to predict it. The persistent hyperbole, the seeming logic validated largely by a disregard for some basic laws of physics, is merely a prelude to the frenzy that the next IPCC report (AR5) is likely to fuel.

To better gird ourselves before the onslaught, it seems like a good time to review another important report, which speaks very clearly to the current arguments about the rate of global warming and the accuracy of the climate models.

‘Biblical’ Amounts of Rainfall Slam Colorado, Causing Death, Destruction, and Massive Flooding

Enough rain fell between Sept. 10-12 to turn 2012 from one of Boulder's driest years into a year that, so far, is rivaling its wettest on record. Click image to enlarge. (Credit: Dennis Adams-Smith/Climate Central)
Massive, historic, “biblical” rainfall cascaded through much of Colorado starting last Thursday.  As of Monday at least six people are believed to have died in the floods, and 1,253 remain unaccounted for, according to the Denver Post.   Boulder has received 21.13 inches of rain since last Monday.

One single event cannot definitively be said to be caused by climate change.  But a study last year found that, as the Earth gets warmer, precipitation patterns shift and we will see more intense downpours, as storms become stronger because they have more energy.

Goal to Cap Temperature Rise Will Still Leave Hundreds of Millions Thirsty

A new study projects that 8 percent of the world's current population, or 486 million people, will soon live in regions at an increased risk of water scarcity, even if the average global temperature rise is limited to 2 degrees Celsius, the cap cited in several U.N. agreements.

If temperatures were to rise 3.5 C over preindustrial levels -- the likely trajectory under current international pledges to cut emissions -- the population forced to live in areas with greater water strain would increase to 11 percent, or 668 million people.

The study shows that people in the Middle East, North Africa, Southern Europe, and the Southwest of the USA will experience the most significant changes.

Wind power is cheap where the wind blows, and by the middle of the next decade, the wind farms that dot the landscapes along the highways in Rocky Mountain states could become major regional sources of electricity without federal subsidies, according to a new National Renewable Energy Laboratory (NREL) study.


Western renewables, primarily wind, could begin to compete on their own with electricity generated at natural gas power plants by 2025, the study said.

Further delay in the implementation of comprehensive international climate policies could substantially increase the short-term costs of climate change mitigation.  Global economic growth would be cut back by up to 7 percent within the first decade after climate policy implementation if the current international stalemate is continued until 2030 -- compared to 2 percent if a climate agreement is reached by 2015 already, a new study shows.
