greenhouse gases

Climate negotiators pressed even harder Monday to reach a global pact to slash greenhouse gases.

(Massachusetts Institute of Technology) A new type of natural-gas electric power plant proposed by MIT researchers could provide electricity with zero carbon dioxide emissions to the atmosphere, at costs comparable to or less than conventional natural-gas plants, and even to coal-burning plants.

But that can only come about if and when a price is set on the emission of carbon dioxide and other greenhouse gases -- a step the US Congress and other governments are considering as a way to halt climate change.

(Max-Planck-Gesellschaft) A new calculation of Europe's greenhouse gas balance shows that emissions of methane and nitrous oxide tip the balance and eliminate Europe's terrestrial sink of greenhouse gases.

The EPA Vehicle Greenhouse Gas (VGHG) model is used to apply various technologies to a defined set of vehicles in order to meet a specified GHG emission target, and to then calculate the costs and benefits of doing so.

Spurred by a warming climate, daily record high temperatures occurred twice as often as record lows over the last decade across the continental United States, new research shows.

The ratio of record highs to lows is likely to increase dramatically in coming decades if emissions of greenhouse gases continue to climb.

Driven by climate concerns and a desire to modernize its economy, Beijing has slowly begun addressing its massive emissions of greenhouse gases.

MAGICC consists of a suite of coupled gas-cycle, climate and ice-melt models integrated into a single software package.

The software allows the user to determine changes in greenhouse-gas concentrations, global-mean surface air temperature, and sea level resulting from anthropogenic emissions of greenhouse gases and aerosols.

SCENGEN constructs a range of geographically explicit climate change projections for the globe using the results from MAGICC together with AOGCM climate change information from the Coupled Model Intercomparison Project (CMIP3) archive.

Proposed regulations would require power plants, factories and refineries to reduce greenhouse gases by installing the best available technology whenever a facility is significantly changed or built.

A federal appeals court ruled Monday that states trying to combat global warming can sue six electric utilities to force them to cut the greenhouse gases emitted by their power plants in 20 states.
