Sentences with phrase «total warming we have seen»

But this shows that level as the basement lowest possible amount, with the highest about matching the total warming we have seen so far since the industrial revolution.

Direct CO2 radiative «greehouse» warming is surely a detectable signal, but only a small fraction of the total warming we've seen.

Not exact matches

Given the total irrelevance of volcanic aerosols during the period in question, the only very modest effect of fossil fuel emissions and the many inconsistencies governing the data pertaining to solar irradiance, it seems clear that climate science has no meaningful explanation for the considerable warming trend we see in the earlier part of the 20th century — and if that's the case, then there is no reason to assume that the warming we see in the latter part of that century could not also be due to either some as yet unknown natural force, or perhaps simply random drift.

John Carter August 8, 2014 at 12:58 am chooses to state his position on the greenhouse effect in the following 134 word sentence: «But given the [1] basics of the greenhouse effect, the fact that with just a very small percentage of greenhouse gas molecules in the air this effect keeps the earth about 55 - 60 degrees warmer than it would otherwise be, and the fact that through easily recognizable if [2] inadvertent growing patterns we have at this point probably at least [3] doubled the total collective amount in heat absorption and re-radiation capacity of long lived atmospheric greenhouse gases (nearly doubling total that of the [4] leading one, carbon dioxide, in the modern era), to [5] levels not collectively seen on earth in several million years — levels that well predated the present ice age and extensive earth surface ice conditions — it goes [6] against basic physics and basic geologic science to not be «predisposed» to the idea that this would ultimately impact climate.»

As a number of scientific articles have shown, most recently by Kevin Anderson and Alice Bows in the Journal of the Royal Society, limiting the world to 2 °C warming most likely requires peaking total global carbon emissions in the next 5 - 10 years followed by immediate reductions to near - zero by 2050 (see Anderson and Bows emission trajectory options here, via David Roberts, and by David Hone here).

Here's step 3 again: 3) Comparing the total warming over two different periods to see which has shown more total warming.

3) Comparing the total warming over two different periods to see which has shown more total warming.

Remember that when you add up all the specific impacts of the type that we have been reviewing here, the total economic costs at 40C of warming — which we would expect to reach sometime into the 22nd century — are estimated by the IPCC to be about 1 — 5 % of global GDP (See WG2 SPM, page 17)

However, since the IPCC provides us with the 95 % confidence range of the total net anthropogenic forcing in Figure 1, we can account for the uncertainties which concern Lindzen, and evaluate how much warming we «should have seen» by now.

This long time constant is mandatory to their claims since if the time constant is short we would have already seen essentially all the impact from half a doubling of CO2 which, using their numbers, is more than half of the total 0.7 C of warming they claim.

In the Washington Times in 2007 he said that his film would change history, and predicted that «in five years the idea that the greenhouse effect is the main reason behind global warming will be seen as total bunk.»

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Taking into account the logarithmic effect of CO2 on temperature, the 35 percent increase we have already seen in CO2 concentrations represents about three - quarters of the total...

We have seen a total linear warming of 0.041 C per decade or 0.66 C over the entire 160 - year HadCRUT record (this has occurred in 3 statistically indistinguishable 30 - year warming cycles, with 30 - year cycles of slight cooling in between, as Girma has shown us graphically).
