The indications are all over that our planet is experiencing major weather switch. it's transparent that we have to lessen the emissions of carbon dioxide and different greenhouse gases from our surroundings if we wish to steer clear of significantly elevated hazard of wear and tear from weather switch. Aggressively pursuing a application of emissions abatement or mitigation will exhibit effects over a timescale of many a long time. How will we actively  Read more...

The RCP scenarios represent a family of hypothetical future scenarios for emission of CO2 and other greenhouse gases. They are labeled according to the peak radiative forcing from all gases up to the year 2100, so that higher-numbered RCP scenarios correspond to climate futures with greater emissions. 5, and the middle two have been selected for the analysis in this section. , carbon dioxide removal) to help meet its target. SOURCE: IPCC, 2013b, Fig. 7. fossil fuels. 1 In order to stabilize or reduce atmospheric concentrations, and thus avoid the worst impacts of warming, global emissions of GHGs must be reduced by at least an order of magnitude (NRC, 2011a).

The carbon dioxide data (red curve), measured as the mole fraction in dry air, on Mauna Loa constitute the longest record of direct measurements of CO2 in the atmosphere; the black curve represents the seasonally corrected data. The collection of this record was begun in 1958 by Charles David Keeling of the Scripps Institution of Oceanography. gov/gmd/ccgg/carbontracker/). SOURCE: Scripps CO2 Program. path toward reducing the threats associated with anthropogenic climate change. , ocean warming, ocean acidification, polar ice melting, sea level rise) would not follow for many decades or even centuries beyond that.

4). In addition, further mitigation options involving the removal of CO2 from the atmosphere may provide cost-effective means to stabilize atmospheric CO2 at concentrations that would limit adverse effects of global warming (IPCC, 2014a). In the sections that follow, the committee discusses various potential methods for removing CO2 from the atmosphere, together with estimates about possible rates of removal and total amounts that might be removed via these methods. 1 summarizes human emissions of CO2 and the associated increase of CO2 in the atmosphere and CO2 sinks since 1750 and in a recent 10-year period.
