According
to recent research into how wind turbines affect local weather, large
wind farms in certain areas in the United States appear to affect local
land surface temperatures, especially at night. The warming trend was
spatially matched to the locations of wind farms, and caused warming by
nearly three-quarters of a degree Celsius.

A new study from scientists at the Lawrence Berkeley National Laboratory has quantitatively demonstrated that black carbon—also known as soot, a pollutant emitted from power plants, diesel engines, and residential cooking and heating, as well as forest fires—reduces the reflectance of snow and ice, an effect that increases the rate of global climate change.

Approximately 75% of electricity used
in the United States
is produced by coal-burning power plants that spew carbon dioxide into
the
atmosphere and contribute to global warming. To reduce this effect, many
researchers are searching for porous materials to filter out the carbon
dioxide
generated by these plants before it reaches the atmosphere, a process
commonly
known as carbon capture. But identifying these materials is easier said
than
done.

A
prolonged solar minimum left the sun's surface nearly free of sunspots
from 2005 to 2010. Total solar irradiance declined slightly as a result,
but according to a recent NASA study, the Earth continued to absorb
more energy than it emitted throughout the minimum.

Engineering our way out of global
climate warming may not be as easy as simply reducing the incoming solar
energy, according to a team of University
of Bristol and Penn State University climate scientists. Designing
the approach to control both sea level rise and rates of surface air
temperature changes requires a balancing act to accommodate the
diverging needs
of different locations.

Commercially
crude oil occupies a region 5 to 10 miles beneath the Earth’s surface,
but there is increasing interest in "abiogenic" hydrocarbons from much
deeper in the Earth, which might make their way to the surface in some
places. A new project to understand this "deep carbon" could affect both
our thinking about energy supplies and the global movement of carbon.

A team led by Lawrence Berkeley National Laboratory scientists hopes to become the first in the world to produce electricity from the Earth’s heat using carbon dioxide. They also want to permanently store some of the carbon dioxide underground. The technology could lead to a new source of clean, domestic energy and a new way to fight climate change.

Scientists
have come up with a possible explanation for why the rise in Earth's
temperature paused for a bit during the 2000s, one of the hottest
decades on record. According to a new study, the culprit was all of the
airborne sulfur pollution from China's massive coal-burning. Despite the
massive output of sulfur, the effect was temporary.

Two Univ. of Minnesota
Department of Earth Sciences researchers have developed an innovative
approach
to tapping heat beneath the Earth’s surface. The method is expected to
not only
produce renewable electricity far more efficiently than conventional
geothermal
systems, but also help reduce atmospheric carbon dioxide (CO2)—dealing
a
one-two punch against climate change.

Recent
reports of record high greenhouse gas emissions and unprecedented
carbon levels in the atmosphere have added a sense of urgency to the
efforts of United Nations climate negotiators, who are trying to make
industrial countries continue reducing greenhouse gas emissions after
their current commitment expires next year.
