and Information system) the GFZ has started to observe the volcano eruption and to provide support on data acquisition and interpretation.

Thomas Walter. On one hand we are analysing data from the newest remote sensing satellites to develop models of the magma ascent path.

The satellite data which is acquired by the European space agency's Sentinel-1 satellite enables the measurement of ground movements associated with the volcano eruption.

and following the path of the magma from depth to its point of eruption. As a result the location of the ascent paths at depth explains well why the eruption site is off-centered with respect to the volcano summit.

which allows for regular updates on the ground movement and the magma ascent path beneath.

The magma's eruption rate has decreased but concerns have arisen about a recent increase of the explosive character of the eruption and related ash dispersion.

#First-of-its-kind tornado panels installed in Montgomery Home in June, UAB's tornado panels designed to protect against flying debris were installed as an integral component of a safe room in a new construction home in the Montgomery, Alabama area.

Uday Vaidya, Ph d.,professor and chair of UAB's Department of Materials science and engineering, worked with Storm Resistant Systems

The UAB panels were approved by the National Storm Shelter Association to hold up against an EF5 tornado."

"This installation comes after four years of research, testing, approvals and manufacturing, following the 2011 Alabama tornado outbreak.

a lot of debris is picked up, and it can actually penetrate inside a house. People die from the debris that comes through the walls or other things,

"With an average of more than 1, 000 tornadoes recorded in the U s. each year, it was crucial that something be done to make homes more safe,

"Those tornadoes result in approximately 80 deaths and 1, 500 injuries each year. Our goal was to develop new technology that would help protect individuals against the impact of debris during natural disasters,

and I think with these panels, we've done just that.""The panels leave the assembly line looking like typical interior walls;

#Farming Now Worse for Climate Than Clearing Forests Efforts such as these to slow deforestation have delivered some of humanity few gains in its otherwise lackadaisical battle so far against global warming.

Efforts such as these to slow deforestation have delivered some of humanity few gains in its otherwise lackadaisical battle so far against global warming.

particularly in Brazil, helped reduce deforestation annual toll on the climate by nearly a quarter between the 1990s and 2010.

A new study describes how this trend has seen agriculture overtake deforestation as the leading source of land-based greenhouse gas pollution during the past decade.

the researchers note that delegates to the talks ignore similar opportunities to reform farming. he decline in deforestation over the past decade

The deforestation slowdown has, n large part, he said, been driven by new forestry rules in Brazil, by the U n. Reducing Emissions from Deforestation and Forest degradation (REDD) program,

which funds forest conservation, and similar policies elsewhere. The new study, led by the U n. Food and agriculture organization

quantifies the reductions in climate pollution from the degradation and clearcutting of forests. Clearcutting most often clears space for agriculture,

suggesting agriculture indirect climate impacts surpass the impacts of deforestation for timber and other commodities. The researchers aim to tally those indirect impacts later this year.

The study is also a reminder that the burning of fossil fuels remains the main cause of global warming.

Burning fuel produces about four times more climate pollution every year than forestry and agriculture combined figure that is growing.

Agricultural climate pollution is caused mostly by livestock. Cows and buffalo are the worst offendersheir ruminating guts

that livestock are blamed for two-thirds of agriculture climate pollution every year. ee seeing an expansion of agricultural lands in some areas because of the growing global population,

Although annual climate pollution from deforestation is declining, experts warn that recent gains could quickly be reversed.

Deforestation in the Amazon rainforest spiked recently following nearly a decade of declines, for example, as farmers and loggers rushed to exploit loopholes in forest protection laws.

Some parts of Central africa are seeing deforestation in areas where it was not previously a problem.

The researchers drew on three global datasets to try to hone in on land changing contribution to global warming.

Such impacts are harder to quantify accurately than are the pollution impacts of burning fuel.

and reporting complex climate indicators for deforestation and agricultural activity than is the case for the energy sector.

The paper noted a gulf between global efforts to reduce the climate impacts of deforestation, and the dearth of a global response to the climate impacts of food production.

REDD is a major focus of U n. climate negotiations but agriculture is discussed barely during the talks. here been a lot of discussion back and forth,

and perhaps a good deal of polemic, about REDD, Steve Schwartzman, director of tropical forest policy at the Environmental defense Fund, said. ut, over time,

I think all the major actors have come to the conclusion that reducing emissions from deforestation is a key piece of solving the climate change puzzle.

and just impose reductions in food production to meet greenhouse gas reduction targets, Schwartzman said. Doug Boucher, the director of climate research at the Union of Concerned Scientists, says agriculture climate impacts could be reduced without taking food off tables.

Reducing the overuse of fertilizers, protecting the organic content of soils by changing farming practices,

The biggest opportunities for reforming agriculture climate impacts can sometimes be found miles from where any food is grown.

whether climate change can be blamed for California's drought, a recent National oceanic and atmospheric administration (NOAA) reportfound climate change was not the cause.

Global warming has caused excessive heat that may have worsened the drought's effects, but it isn't necessarily to blame for the lack of rain.

It's true that recent years have yielded much less rain and snow than previous times in history,

but that's just a result of"natural variance"and not necessarily because of man-made pollution.

To the extent that climate change exacerbates the drought California's efforts to curb greenhouse gas emissions may eventually help.

the warmer the atmosphere becomes, exacerbating global climate change. Solving the problem is not so simple, especially with regards to aviation the source of two-percent of the annual greenhouse gas emissions from human activity.

While biofuels have proven to be an effective, renewable, low-carbon alternative to gasoline and diesel, jet fuels pose unique challenges.

and the BP energy company. ee combined chemical catalysis with life-cycle greenhouse gas modeling to create a new process for producing bio-based aviation fuel as well as automotive lubricant base oils,

density and viscosity that could achieve net life-cycle greenhouse gas savings of up to 80-percent. Bell is one of three corresponding authors of a paper describing this research in the Proceedings of the National Academy of Sciences (PNAS.

and lubricants from biomass optimized using life-cycle greenhouse gas assessment. Corinne Scown, a research scientist with Berkeley Lab Energy Analysis and Environmental impacts Division,

and Dean Toste, a chemist with joint appointments at Berkeley Lab and UC Berkeley, are the other two corresponding authors.

Biofuels synthesized from the sugars in plant biomass help mitigate climate change. However jet fuels have stringent requirements that must be met. et fuels must be oxygen-free,

but offer only modest greenhouse gas reduction benefits. Ours is the first process to generate true drop in aviation biofuels.

Lubricant base oils can produce even more greenhouse gas emissions on a per-mass basis than petroleum-derived fuels

In their PNAS paper the authors acknowledge that the commercial implementation of their proposed process would include financial implications that extend beyond greenhouse gas emission reductions
