Sentences with phrase «range of climate sensitivity»

The key is to redo their work, use a series of models with a wide range of climate sensitivity parameters... you know what to do.

This is why climate researchers talk about probable ranges of climate sensitivity.

Current national and international innovation programs are not sufficient to effectively manage the risk of policy failure or higher ranges of climate sensitivity.

Other studies show a wide range of climate sensitivities.

A continuing negative feedback carbon cycle response, in conjunction with restraint on human emissions, plus some luck with experiencing the lower ranges of climate sensitivity, could lead to climate change of, let's say, 2 °C.

d Explores IPCC TAR range of climate sensitivity (i.e., 1.5 °C to 4.5 °C), while other studies explore wider ranges

In general, because the difference between today's cumulative emissions and those in a 1.5 C world are so small, they are quite sensitive to many different factors, including how much observed warming has occurred to date, how much non-CO2 emissions are expected in the future, what range of climate sensitivity is used in calculating the 66 % chance of avoiding, and many other issues.

Like how can there be this pause we're seeing when the accepted range of climate sensitivity and GCMs can't duplicate it without subtracting CO2 induced warming.

Taken at 1970, the IPCC likeley (ie, 67 % confidence interval) range of climate sensitivities generates lags from 6 to more than 39 years using the 1880 - 1909 baseline.

The AR4 gives the uncertainty range of climate sensitivity as 2 - 4.5 ºC warming for CO2 doubling, so there still is about a factor of 2 uncertainty and Broecker used a value near the very low end of this uncertainty range.

This graph shows that even at the lowest range of climate sensitivity, future global warming will take us well beyond any temperature experienced during civilized human history.

Hansen and Sato argue that the probable range of climate sensitivity values is not as large as currently believed (unlikely to fall outside the range of 2 to 4 °C for doubled CO2)- both very high and very low values can effectively be ruled out using paleoclimate data.

As discussed in Chapter 10 and throughout the last three IPCC assessments, climate models exhibit a wide range of climate sensitivity estimates (Table 8.2).

Harvey and Kaufmann (2002), who use an approach that focuses on the TAR range of climate sensitivity, further conclude that global mean forcing from fossil - fuel related aerosols was probably less than — 1.0 W m — 2 in 1990 and that global mean forcing from biomass burning and anthropogenically enhanced soil dust aerosols is «unlikely» to have exceeded — 0.5 W m — 2 in 1990.

While the CO2 growth rate in the figure is based on A1F1 — a high end emission scenario yes, but not one that can be easily ruled out as impossible — the response uses a wide range of climate sensitivities that span the possible range.

M2009 use a range of climate sensitivities to compute a probability distribution function for expected warming, and then McKibben [255] selects the carbon emission limit that keeps 80 % of the probability distribution below 2 °C.

Using the middle of the range of climate sensitivities of 3 oC of warming at equilibrium per doubling of [CO2], a rise of [CO2] from 280 - 310 ppm should give 0.44 oC at equilibrium.

I notice the range of climate sensitivity reported for your various models is 2.4 C to 2.8 C. Those values are lower than what some people would expect.

This gives a range of climate sensitivity that is much larger than the IPCC range (1.5 to 4.5 deg C for a doubling of CO2), and which therefore translates to wider bounds on possible climate projections both at the high end and low end.

The results of the analysis demonstrate that relative to the reference case, projected atmospheric CO2 concentrations are estimated by 2100 to be reduced by 3.29 to 3.68 part per million by volume (ppmv), global mean temperature is estimated to be reduced by 0.0076 to 0.0184 °C, and sea - level rise is projected to be reduced by approximately 0.074 — 0.166 cm, based on a range of climate sensitivities.
