The battle to reduce greenhouse gas emissions and prevent the most dangerous consequences of climate change will be waged across multiple fronts, including efforts to increase energy efficiency; efforts to deploy nonfossil fuel sources, including renewable and nuclear energy; and investment in adaptation to reduce the impacts of the climate change that will occur regardless of the actions we take.

The possibility that substantial quantities of CO2 can be injected into subsurface porous rock formations has been investigated sufficiently to show that pore space available to contain the CO2 is abundant. Multiple rock types and physical mechanisms can be used to trap the CO2 indefinitely. With careful site selection and operations, leakage to the near-surface region can be avoided.

In the coming weeks, on the plains of Inner Mongolia, China will launch
its first large-scale effort to capture and store carbon emissions from
a power plant.

Overwhelming scientific evidence shows that CO2 emissions
from fossil fuels have caused the climate to change, and a dramatic
reduction of these emissions is essential to reduce the risk of future
devastating effects. On the other hand, access to energy is the basis
of much of the current and future prosperity of the world.

To slow the atmospheric buildup of CO2, a report from the
U.S. National Research Council recently called for building a suite of
15 to 20 power plants with carbon capture and storage (CCS) before
2020. "The urgency of getting started on these demonstrations to
clarify future deployment options cannot be overstated," the report
said.

Novel Pollution-Control Experiment At American Power Plant Draws Visitors From India & China

Poking out of the ground near the smokestacks of the Mountaineer power plant here are two wells that look much like those that draw natural gas to the surface. But these are about to do something new: inject a power plant

Using Africa's vast agricultural resources to help tackle climate change could earn the continent $1.5 billion a year, a World Bank head said on Tuesday.

The region should also tap its underexploited renewable resources, particularly hydropower, to meet increasing energy demand and boost both growth and development.

Farmers worldwide managed 32.2 million hectares of agricultural land organically in 2007, nearly 5 percent more than in the previous year and a 118-percent increase since 2000. Organic farming is now reported in 141 countries; about two thirds of this land area is in industrial countries, and nearly half of the producers are in Africa.

The post-Copenhagen world requires a fresh look at the big picture. In the absence of international agreements, what steps can be taken nationally, regionally and locally to reduce both carbon emissions and carbon concentrations?

Climate change and forests are intrinsically linked. On the one hand, changes in global climate are already stressing forests through higher mean annual temperatures, altered precipitation patterns and more frequent and extreme weather events. At the same time, forests and the wood they produce, trap and store CO2, play a major role in mitigating climate change.
