Phosphorus is also accumulating in ecosystems at a rate of 10.5 – 15.5 teragrams per year, compared with a preindustrial rate of 1 – 6 teragrams per year, mainly as a result of the use of phosphorus (obtained through mining) in agriculture. ❋ Unknown (2008)
The flux of reactive nitrogen to the oceans increased by nearly 80% from 1860 to 1990, from roughly 27 teragrams (1012 grams) of nitrogen per year to 48 teragrams in 1990 (R9). ❋ Unknown (2008)
In preindustrial times, the annual flux of nitrogen from the atmosphere to the land and aquatic ecosystems was roughly 110 – 210 teragrams of nitrogen a year. ❋ Unknown (2008)
The atmosphere contains 4,850 teragrams of methane, 4.85 billion metric tons. ❋ James Killus (2007)
Recent studies estimate that global dust-emission rates falls within a range from less than 1000 to 3000 teragrams (Tg) yr – 1, and about 80% of the dust is from the Northern Hemisphere. ❋ Unknown (2007)
Volcanic activity now releases about 130 to 230 teragrams 145 million to 255 million short tons of carbon dioxide each year. ❋ Unknown (2007)
According to the EPA, total U.S. greenhouse gas emmissions for 2004 were 7,074.4 teragrams of carbon dioxide equivalents. ❋ Unknown (2006)
“Volcanic CO2 emissions are about 130-230 million teragrams” ❋ Unknown (2006)
Volcanic CO2 emissions are about 130-230 million teragrams / year. ❋ Unknown (2006)
The increase in Asia was 70 percent (from 6.8 teragrams of nitrogen to 11.5 teragrams). ❋ Unknown (2000)
The ecologically driven scenario (chapter 9), for example, would lower global 2020 emissions from 59 teragrams of sulphur to 34 teragrams. ❋ Unknown (2000)
A mid-range estimate is 20 teragrams of sulphur, to be achieved if all large, new facilities are fitted with flue-gas desulphurisation units and other fossil-fuel users switch to low-sulphur fuels. ❋ Unknown (2000)
The official (but undocumented) estimate for Chinas emissions in 2020 is 19.5 teragrams of sulphur. ❋ Unknown (2000)
The main problem region is Asia, where emissions are already high-with 17 teragrams of sulphur emissions in 1990-and could double by 2020. ❋ Unknown (2000)
In 1990 ammonia emissions in Asia were 22.5 teragrams, compared with 3.5 teragrams in Western Europe and 4.1 teragrams in North America. ❋ Unknown (2000)
In 1990 energy-related activities accounted for just 5 percent of global ammonia emissions-2. 7 of 52.0 teragrams (Olivier and others, 1998). ❋ Unknown (2000)
Driven by a similar energy forecast, the model projects that Asias sulphur dioxide emissions in 2020 will be bounded by an upper value of 40 teragrams of sulphur (under the assumption of no further control policies beyond those in place in 1990-the NFC scenario) and a lower value of 6 teragrams of sulphur (with the assumption of very tight controls, similar to those in Western Europe). ❋ Unknown (2000)
Emissions of 11.9 teragrams of sulphur in 1995 are used as a baseline, and the plan is to limit national emissions to 12.3 teragrams of sulphur in 2000 by capping emissions in certain provinces at their 1995 levels. ❋ Unknown (2000)
Now for the cost of all this: they estimated that 2030 emissions could be reduced by 110 teragrams Tg, 10 ❋ Kyle Niemeyer (2012)
