Sentences with phrase «gtc reforestation»

if we assume only 50 GtC reforestation».

So, Hansen is proposing «at least 6 % / year» emissions reduction starting now, with the requirement for 100 GtC reforestation, and «about 9 % / year.....

(A) 6 % or 2 % annual cut begins in 2013 and 100 GtC reforestation drawdown occurs in 2031 — 2080, (B) effect of delaying onset of emission reduction.

A 6 % / year decrease of fossil fuel emissions beginning in 2013, with 100 GtC reforestation, achieves a CO2 decline to 350 ppm near the end of this century (Fig. 5A).

In contrast, warming reaches 1.5 °C and stays above 1 °C until after 2400 if emissions continue to increase until 2030, even though fossil fuel emissions are phased out rapidly (5 % / year) after 2030 and 100 GtC reforestation occurs during 2030 — 2080.

In contrast, warming reaches 1.5 °C and stays above 1 °C until after 2400 if emissions continue to increase until 2030, even though fossil fuel emissions are phased out rapidly (5 % / year) after 2030 and 100 GtC reforestation occurs during 2030 — 2080.

If we assume only 50 GtC reforestation, and begin emissions reduction in 2013, the required reduction rate becomes about 9 % / year.

A 6 % / year decrease of fossil fuel emissions beginning in 2013, with 100 GtC reforestation, achieves a CO2 decline to 350 ppm near the end of this century (Fig. 5A).

Not exact matches

With the stable climate of the ∼ 1 °C scenario it is plausible that major efforts in reforestation and improved agricultural practices [15], [173], [175]--[177], with appropriate support provided to developing countries, could take up an amount of carbon comparable to the 100 GtC in our ∼ 1 °C scenario.

Ironically, Australia's Garnaut Report does accept there is a CO2 biospheric Uptake and that reforestation etc would absorb CO2, but in his modelling abstracts from this effect, which last year accounted for 5.78 GtC of the 10 GtC of global emissions.

According to Hansen et al. (2008, note 2 above), «It is assumed that uptake of carbon via reforestation will increase linearly until 2030, by which time reforestation will achieve a maximum potential sequestration rate of 1.6 GtC per year (S28).

Our reforestation scenarios assume that today's net deforestation rate (∼ 1 GtC / year; see [54]-RRB- will stay constant until 2020, then linearly decrease to zero by 2030, followed by sinusoidal 100 GtC biospheric carbon storage over 2031 — 2080.

With the stable climate of the ∼ 1 °C scenario it is plausible that major efforts in reforestation and improved agricultural practices [15], [173], [175]--[177], with appropriate support provided to developing countries, could take up an amount of carbon comparable to the 100 GtC in our ∼ 1 °C scenario.

al. (2011) estimate the total 21st century biosequestration potential at 100 GtC, which is equivalent to about 370 Gt CO2, based entirely on afforestation and reforestation.

With the stable climate of the ~ 1 °C scenario it is plausible that major efforts in reforestation and improved agricultural practices, with appropriate support provided to developing countries, could take up an amount of carbon comparable to the 100 GtC in our ~ 1 °C scenario.
