Sentences with phrase «carbon cycle feedbacks»

Only by including carbon cycle feedbacks and longer time periods than 100 years in your projections can you come up with realistic long - term temperature estimates.

It also depends on other factors like emissions / concentrations and e.g. carbon cycle feedback.

Current status: Researchers are working to understand how carbon cycle feedbacks will alter future CO2 concentrations.

In addition to the aerosol and albedo feedbacks that will occur during these next few decades, the additional warming will produce carbon cycle feedbacks.

By including fast carbon cycle feedbacks, the team showed that 3 C could possibly reverse the sign of net carbon flows between atmosphere and land.

Chapter 10 considers the possibilities for future carbon cycle feedbacks.

There could be other hypotheses involving fluctuations in solar intensity, frequent volcanoes shooting sulfate aerosols into the stratosphere, or rapid carbon cycle feedbacks.

The lighter shaded areas depict the change in this uncertainty range, if carbon cycle feedbacks are assumed to be lower or higher than in the medium setting... Global mean temperature results from the SCM for anthropogenic and natural forcing compare favourably with 20th - century observations (black line) as shown in the lower left panel (Folland et al., 2001; Jones et al., 2001; Jones and Moberg, 2003).

Evaluation of the terrestrial carbon cycle, future plant geography and climate - carbon cycle feedbacks using five Dynamic Global Vegetation Models (DGVMs)

In 2006, the Hadley Centre, working with other British researchers, published an important study, «Impact of Climate - Carbon Cycle Feedbacks on Emissions Scenarios to Achieve Stabilisation,» that included both ocean and terrestrial carbon cycle feedbacks (though they do not specifically model carbon emissions from defrosting tundra).

If concentrations start rising quicker due to positive carbon cycle feedback, then IPCC might be willing to lower ECS to say 2 degrees, because you can still claim there is big problem.
