Senators Kevin de León and Fran Pavley announced a package of new legislation that builds on Gov. Brown’s state of emergency declaration to ensure protections for Californians impacted by the natural gas leak in Porter Ranch. 

The new legislation will require: 

• a moratorium on new injections into the Aliso Canyon  storage facility until experts determine it is safe to resume and a study to see whether it makes sense to continue using the facility. (SB 875)
• that response costs – such as greenhouse gas mitigation, relocation, and emergency response costs – will be funded by the Gas Company shareholders, not the ratepayers who are suffering from this disaster. (SB 876)
• stronger laws regulating gas storage facilities, including increased inspections and health and safety measures. (SB 877)
• setting state climate pollution reduction targets and holding polluters accountable for meeting those targets. (SB 878)

Low raw material costs have dealt a heavy blow to the recycling industry. The French recycling federation (FEDEREC) believes the sector needs a complete overhaul to stay afloat in the coming years.

FEDEREC published its view of the future of recycling in a white paper entitled "The recycling industry by 2030." In the preface to this 70-page document, a frank discussion of the problems facing the industry and how they might be solved, Corinne Lepage, a Republican politician, evoked a sector "devastated by an oil price that is so low that it is driving us back towards a linear economy, as it is cheaper today to buy primary raw materials than recycled raw materials".

For the past six years, researchers at the Universitat Politènica de València (Polytechnic Univeristy of Valencia, UPV) have been studying the performance of twelve Aleppo pine varieties native to different regions of Spain in reforestation campaigns across three national forest areas. Different varieties or genotypes have different levels of resistance to cold and drought, which influence how well they perform in a given geographical region, and researchers wanted to find out which varieties worked best and where.

To do so, the different national varieties or genotypes were used to repopulate forest areas in La Hunde, Valencia (as the control region), in the drier Granja d'Escarp, Lleida, to the north and further inland in Tramacastiel, Teruel, where the climate is much cooler.

"The varieties from Inland Levante and La Mancha performed the best overall, while those from further south seem to be perfect for reforestation efforts in regions already affected by climate change," observes Antonio del Campo, researcher at the UPV's Institute of Water and Environmental Engineering (IIAMA).

There were high-fives this week from Detroit to Washington, D.C., as carmakers celebrated record auto sales.

Americans bought 17.5 million cars and trucks in 2015. That's a huge turnaround from 2009, and the Obama administration cheered the rebound as vindication of the president's decision to rescue General Motors and Chrysler from bankruptcy.

"Because of the policy decisions that were made by this administration to place a bet on those workers, America has won, and our economy has been better for it," White House spokesman Josh Earnest told reporters Wednesday.

Despite their diversity, the structure of most tropical rainforests is highly predictable. Scientists have described the various sizes of the trees by a simple mathematical relationship called a power law.

In a new study using data from a rainforest in Panama, researchers determined that competition for sunlight is the underlying cause of this common structure, which is observed in rainforests around the globe despite differences in plant species and geography. The new finding can be used in climate simulations to predict how rainforests absorb excess carbon dioxide from the atmosphere.

A new study finds that human activities are likely contributing far less nitrogen to the open ocean than many atmospheric models suggest. That's generally good news, but it also nullifies a potential side benefit to additional nitrogen, says Meredith Hastings, associate professor of Earth, environmental and planetary sciences at Brown University and one of the study's co-authors.

"People may not be polluting the ocean as much as we thought, which is a good thing," said Hastings, who is also a fellow at the Institute at Brown for Environment and Society. "However, additional nitrogen could potentially stimulate the ocean's ability to draw down carbon dioxide out the atmosphere, which might counteract carbon emissions to some extent. But if we're not adding as much nitrogen, we're not getting that potential side benefit in the carbon cycle."

Meeting the Paris Climate Agreement goal of limiting the increase in the global average temperature to well below two degrees Celsius compared to pre-industrial levels will require increased use of renewable energy and reducing the CO2 intensity of fossil energy use.

The intermittency of when the wind blows and when the sun shines is one of the biggest challenges impeding the widespread integration of renewable energy into electric grids, while the cost of capturing CO2 and storing it permanently underground is a big challenge for decarbonizing fossil energy.

However, researchers from Lawrence Livermore National Laboratory, Ohio State University, University of Minnesota and TerraCOH, Inc. think they’ve found an answer to both of these problems with a large-scale system that incorporates CO2 sequestration and energy storage.

Two-and-a-half billion people worldwide have no access to safe, durable sanitation systems. Brian Arbogast, director of the water, sanitation and hygiene programme at the Bill & Melinda Gates Foundation, tells SciDev.Net how innovative toilet technologies and business models could help fix this — and help communities cope with the devastation of climate change.

How does climate change impact sanitation?

With sea levels rising, you have flooding that causes huge health problems. As latrines and septic tanks get flooded and waste goes into the streets and streams, it can carry a lot of disease, including cholera, dysentery and typhoid.

The problem is that the world has only one gold standard for sanitation, which is having flush toilets connected to sewer lines, that are further connected to big and expensive wastewater treatment plants. Growing cities that already have water shortages may not have enough water for everybody to bathe and cook, let alone to flush toilets. So, are these cities going to follow the same path we have taken for the last century in developed cities?

A KPMG study shows that the cost of solar power in India, revealed by public auctions, is barely half a cent above that of cheap local coal , writes Chris Goodall, with generators bids falling well below 5p (UK) / 7¢ (US) per kWh. The idea put about at COP21 that India and other poor but sunny countries need coal to develop their economies is fast running out of steam.

When the accountants have fully loaded the network and other costs PV ends up as very slightly cheaper than using lndian-mined coal. And, of course, this advantage will grow as solar gets cheaper.

Commentators eager to arrest the move towards renewable energy are facing increasing difficulties finding arguments for the continued use of fossil fuel.

Last June, Pope Francis released his much-anticipated encyclical on the environment, Laudato Si’, which received tremendous praise from diverse quarters. The same day, Coral Davenport, writing in the New York Times, noted that the papal encyclical "is as much an indictment of the global economic order as it is an argument for the world to confront climate change." Ms. Davenport quoted me (accurately) as saying that elements of the encyclical were unfortunately "out of step with the thinking and the work of informed policy analysts around the world." In this column, I will elaborate.

First of all, the Pope is to be commended for taking global climate change seriously, and for drawing more world attention to the issue. There is much about the encyclical that is commendable, but where it drifts into matters of public policy, I fear that it is — unfortunately — not helpful.

The long encyclical ignores the causes of global climate change: it is an externality, an unintended negative consequence of otherwise meritorious activity by producers producing the goods and services people want, and consumers using those goods and services. That is why the problem exists in the first place. There may well be ethical dimensions of the problem, but it is much more than a simple consequence of some immoral actions by corrupt capitalists. The document also ignores the global commons nature of the problem, which is why international cooperation is necessary.
