Based on a unique model that links China's energy system and economy, the study finds that China's coal use, a major source of global carbon dioxide (CO2) emissions, should peak some time around the year 2020, while the country's overall CO2 emissions would peak around 2030, or perhaps sooner.

Even the 350 - ppm limit for carbon dioxide is «questionable,» says physicist Myles Allen of the Climate Dynamics Group at the University of Oxford, and focusing instead on keeping cumulative emissions below one trillion metric tons might make more sense, which would mean humanity has already used up more than half of its overall emissions budget.

Defines «reporting entity» to mean: (1) a covered entity; (2) an entity that would be covered if it had emitted, produced, imported, manufactured, or delivered in 2008 or any subsequent year more than the applicable threshold level of carbon dioxide; (3) other entities that EPA determines will help achieve overall goals of reducing global warming pollution; (4) any vehicle fleet with emissions of more than 25,000 tons of carbon dioxide equivalent on an annual basis, if its inclusion will help achieve such reduction; (5) any entity that delivers electricity to a facility in an energy - intensive industrial sector that meets the energy or GHG intensity criteria.

For example, this poll is a bit old (from 2009), but it shows that ``... 58 % support a tax on carbon emissions to create incentives to reduce emissions and increase efficiency, and that provides tax refunds to individuals and households to offset the overall impact of the carbon tax....»

Truly only one negative feedback in the planet's overall carbon cycle can act with sufficient speed and strength to avert catastrophic climate impacts: The dominant carbon - based life form on this planet will have to respond to the already painfully clear impacts of our carbon emissions by slashing those emissions sharply and eventually running the planet on carbon - negative power.

Ms. Redford needs to propose a carbon price that actually leads to overall emissions reductions so that the oil industry takes on its share of Canadian emissions reductions, just like everyone else does.

Various organizations have published forecasts of the economic impacts of the Clean Power Plan (CPP), EPA's regulation that limits carbon dioxide emissions from power plants, with studies arriving at markedly different conclusions about the effect of the policy on electricity affordability and the overall economy.

In other words, if it continues, the recent trend in sea ice loss may triple overall Arctic warming, causing large emissions in carbon dioxide and methane from the tundra this century (for a review of recent literature on the tundra, see «Science stunner: Vast East Siberian Arctic Shelf methane stores destabilizing and venting; NSF issues world a wake - up call: «Release of even a fraction of the methane stored in the shelf could trigger abrupt climate warming»).

The overall net emission over this period = + 0.5 units yet we can see how anthropogenic and sea (e.g. warming) contribute equally to this figure while net natural emission (i.e. sea + land) is — 0.5 Do we really know enough about the carbon cycle, in particular the natural fluxes of CO2, to rule out that some thing like this is going on?

Working on solar geoengineering and carbon dioxide removal today is overall a good thing except insofar as actions taken today to reduce emissions reflect an expectation that these technologies should and will be deployed at large scale at some point in the future.
