To
the world's military leaders, the debate over climate change is long
over. They are preparing for a new kind of Cold War in the Arctic,
anticipating that rising temperatures there will open up a treasure
trove of resources, long-dreamed-of sea lanes and a slew of potential
conflicts.

According
to a new study using SWITCH, a highly detailed computer model of the
electric power grid, University of California, Berkeley researchers have
learned that goals for decarbonization of the electric power sector are
most easily achieved using renewable or nuclear energy sources in lieu
of coal.

According
to recent research led by a chemist at the University of California,
Irvine, airborne gases settle in smog particles from which they cannot
escape. This result could explain why pollution computer models
underestimate organic aerosols, the least understood component in
climate change calculations.

In
the United States, fluoride is often added to drinking water and
toothpaste to help strengthen teeth. But too much naturally occurring
fluoride can cause fluorosis, a darkening of the teeth and sometimes
debilitating skeletal effects. Efforts are underway to use
aluminum-coated bone char to filter water in Africa, but overcoming
local stigmas is a challenge.

Caving
to public pressure, Beijing environmental authorities started releasing
more detailed air quality data Saturday that may better reflect how bad
the Chinese capital's air pollution is. But one expert says
measurements from the first day were low compared with data U.S.
officials have been collecting for years.

A
U.N. climate conference reached a hard-fought agreement Sunday on a
complex and far-reaching program meant to set a new course for the
global fight against climate change for the coming decades. The United
States was a reluctant supporter, concerned about agreeing to join an
international climate system that likely would find much opposition in
the U.S. Congress.

A report released late Thursday in London and discussed Friday at the U.N. climate conference in South Africa said that—in theory—reflecting a small amount of sunlight back into space before it strikes the Earth's surface would have an immediate and dramatic effect. But no one knows what the side effects would be.

The
world pumped about 564 million more tons of carbon into the air in 2010
than it did in 2009. This represents an increase of 6%, and is more
carbon emissions than the worst scenario figures offered by
climatologists four years ago.

The
first international survey by a peer-reviewed journal on the public
perception of geoengineering and solar radiation management has found
that 72% of respondents approved research into these
climate-manipulating techniques.

On
Thursday, California formally adopted the nation's most comprehensive
so-called "cap-and-trade" system. The system will be an experiment by
the world's eighth-largest economy to provide financial incentives for
polluters to reduce greenhouse gas emissions. Some businesses claim it
will hurt job growth and increase electricity costs; proponents say it
will do the opposite.
