THE next United Nations climate report will ''scare the wits out of everyone'' and should provide the impetus needed for the world to finally sign an agreement to tackle global warming, the former head of the UN negotiations said.
Yvo de Boer, the UN climate chief during the 2009 Copenhagen climate change talks, said his conversations with scientists working on the next report of the Intergovernmental Panel on Climate Change suggested the findings would be shocking.
"That report is going to scare the wits out of everyone,'' Mr de Boer said in the only scheduled interview of his visit to Australia. "I'm confident those scientific findings will create new political momentum.''
He said superstorm Sandy may spur more Americans, and people elsewhere, to consider the risks of climate change, but warned: "It's a bit like being shocked into stopping smoking when you've been told you've got terminal cancer."
The IPCC's fifth assessment report is due out in late 2013.

[font size=3]The percentage of Americans saying there is solid evidence of global warming has steadily increased over the past few years. Currently, 67% say there is solid evidence that the earths average temperature has been getting warmer over the past few decades, up four points since last year and 10 points since 2009.
Similarly, an increasing proportion say that the rise in the earths temperature has mostly been caused by human activity. Currently, 42% say the warming is mostly caused by human activity, such as burning fossil fuels, while 19% say it is mostly caused by natural patterns in the earths environment. Last year, 38% mostly attributed global warming to human activity and in 2010 34% did so.

1981
Atmospheric models aren't that damn difficult, they just need basic physics to understand. The problem is scientists must interpret the models and the error bars are massive (2-6C, wtf?!?) so they have err'd on the lower end of estimations, not having any sense of the feedbacks (or negative feedbacks) that the system has.
It's turning out that there aren't many negative feedbacks at all. Cloud cover? Less. Plant sequestration? Less. Oceanic absorption? Decreasing rapidly.

(62,276 posts)That is the hallmark of science.
They need to stress, absolutely stress, that the interpretations have to this point been wrong, and that the effects have been higher than their interpretations have been. That is a fact, a scientific fact, so they will not be "hurting" by pointing that out.
This is not to say that they should simply magically pick the higher end projections.
Merely make it clear that the interpretations to this point (likely because the scientists were afraid to tell the truth) have been on the low end and inaccurate.

But on one end, the other extreme could prove to be even more damaging in the long run: fearmongerers such as Malcolm P.R.

(8,445 posts)11C was already within the realm of possibility when established models did not take strong methane feedbacks into account.
And you do realize that the Permian extinction included severe ocean anoxia once the atmosphere hit about 900ppm of carbon? It caused the biochemistry of the oceans to change drastically resulting in toxic levels of hydrogen-sulfide gas both in the sea and on land. About 95% of all living things died in that event.
Current emission rates place us at 900ppm of carbon by 2100.

That's where the 16 degree number comes from. McPherson didn't just pull it out of his ass.
You can read the piece in Science in which Kiehl lays it out, but here are a couple of excerpts:
What was Earth's climate like at the time of past elevated CO2? Consider one example when CO2 was ?1000 ppmv at ?35 million years ago (Ma) (2). Temperature data (5, 6) for this time period indicate that tropical to subtropical sea surface temperatures were in the range of 35° to 40°C (versus present-day temperatures of ?30°C) and that sea surface temperatures at polar latitudes in the South Pacific were 20° to 25°C (versus modern temperatures of ?5°C). The paleogeography of this time was not radically different from present-day geography, so it is difficult to argue that this difference could explain these large differences in temperature. Also, solar physics findings show that the Sun was less luminous by ?0.4% at that time (7). Thus, an increase of CO2 from ?300 ppmv to 1000 ppmv warmed the tropics by 5° to 10°C and the polar regions by even more (i.e., 15° to 20°C).
What can we learn from Earth's past concerning the climate's sensitivity to greenhouse gas increases? Accounting for the increase in CO2 and the reduction in solar irradiance, the net radiative forcingthe change in the difference between the incoming and outgoing radiation energyof the climate system at 30 to 40 Ma was 6.5 to 10 W m?2 with an average of ?8 W m?2 (see the second figure). A similar magnitude of forcing existed for other past warm climate periods, such as the warm mid-Cretaceous of 100 Ma (8). Using the proxy temperature data and assuming, to first order, that latitudinal temperature can be fit with a cosine function in latitude (9), the global annual mean temperature at this time can be estimated to be ?31°C, versus 15°C during pre-industrial times (around 1750) (10). Thus, Earth was ?16°C warmer at 30 to 40 Ma. The ratio of change in surface temperature to radiative forcing is called the climate feedback factor (11). The data for 30 to 40 Ma indicate that Earth's climate feedback factor was ?2°C W?1 m?2. Estimates (1, 11) of the climate feedback factor from climate model simulations for a doubling of CO2 from the present-day climate state are ?0.5 to 1°C W?1 m?2. The conclusion from this analysisresting on data for CO2 levels, paleotemperatures, and radiative transfer knowledgeis that Earth's sensitivity to CO2 radiative forcing may be much greater than that obtained from climate models.
Kiehl himself quotes paleoclimate research to say that +16C was in fact an average global increase. However, even if it was just just +16 at the poles, that would imply at least +6C at the tropics, with something between those values as a global average. Apparently that's not so far-fetched after all, when one considers the uncertainties around the climate feedback factor and the potential for methane feedbacks.
Both the higher climate feedback due to forcing and the 1000+ ppmv CO2 level by 2100 are supported by IPCC models (specifically A2 and A1FI). Granted, those are among their worst-case scenarios - an average temperature rise of almost +7C is part of the A1FI scenario - but given how circumspect the IPCC boffins have to be, I'm inclined to include them in the range of legitimate discussion. Which is exactly what McPherson is doing.
I'm not sure why you don't like the IPCC, the National Center for Atmospheric Research or Science magazine, but I'm satisfied that McPherson isn't actually going out on much of a scientific limb at all. I think Guy is a model of probity compared to your rather hysterical rejection of what he says and your inability to report it honestly.
AverageJoe90
(10,745 posts)I don't know so much about the far future, but if Kiehl's trying to tell us that 16*C is likely, or even possible, by 2100, then he'd be dead wrong as well.
I'm not sure why you don't like the IPCC, the National Center for Atmospheric Research or Science magazine
I never said or even implied that I didn't like the IPCC, Paul, and I never said anything about the latter two organizations. What were you thinking when you wrote this, exactly?
Apparently that's not so far-fetched after all,
Actually, it very much IS farfetched, especially if he was insinuating that this was the average temperature worldwide and not just at the poles; and even if it was at the poles, it might be a bit of a stretch.
This graph, here, lays out all of the world's average high temperatures over the past half a billion years or so:
While it may not take very short lived temperature spikes into account, it does appear that at no time in the recorded history of life on this planet after the Cambrian, did temperatures ever go above around 8*C above the 20th century average.
I think Guy is a model of probity compared to your rather hysterical rejection of what he says
Hysterical? Hmm....well, compared to some of the stuff I've seen over time, both here and in other places, I'd say that even my most dispassionate tangents so far would be more akin to Peter Jennings reading the headlines on an average ABC World News newsday.
and your inability to report it honestly.
And, why exactly, do you think this?
Also, here's what the IPCC says re: feedbacks:
http://www.ipcc.ch/publications_and_data/ar4/syr/en/mains2-3.html
So, yeah, it basically spells it out; feedbacks ARE included in the models.
GliderGuider
(21,088 posts)Ice cores give temperature at a single location. It's therefore incorrect to say that Vostok represents "The Temperature of Planet Earth" - more mathematical calculations (and thus more assumptions) are necessary to arrive at an estimate of the global mean temperature temperature. Romm reprints one of the references above (#10):
The cosine temperature expression can be integrated analytically to obtain the global annual mean temperature. Paleotemperatures from (5) for a subtropical location and a high southern latitude location were used to determine the two coefficients in the analytical expression for global mean temperature.
And notice the red caption that says "Polar Ocean Equivalent", that goes to +12C?
Wikipedia has this to say:
http://en.wikipedia.org/wiki/Eocene
My takeaway is that the models are missing some significant data, since I tend to trust the proxy records, at least within limits.
The AR4 page you point to does not include methane feedbacks. Two of the scenarios the IPCC use project feedbacks in line with what Hansen has estimated (+6C for doubled CO2) as opposed to the +3 that the IPCC has chosen as "most likely", as well as projections for CO2 beyond 1000 ppmv.
Why do you not dig into the science any deeper than it takes to confirm your biases? It's all well and good to have opinions, but when that extends extend to rubbishing the conclusions of scientists doing real research for top national institutions like NCAR and NASA, who publish their results in reputable journals, you'd better have more than opinion to go on.
+16C by 2100 seems like a stretch, but if men like Kiehl and Hansen say something like it is possible, and the science doesn't preclude it, we'd damn well better talk about it.

I have done plenty of digging, Paul, and like it or not, what I've found over the years doesn't really jive with your assertions. Granted, not every calculation takes, or has taken, feedbacks into account. But the ones that do, do suggest that somewhere up to a 6-7*C rise is possible by 2100 if all feedbacks, including methane, btw, play out to their worst possible effect(and possibly quite a bit more after 2100, though I think we may need more advanced modelling for more than a century or so.), but nothing really more than that. That indeed would be disastrous, and again, nobody can, at this moment, really predict how far AGW effects could go beyond 2100 if they aren't stopped. But 16*C by 2100 just isn't plausible by any stretch.
As for Romm's claims that the Earth was 15*C warmer during some point in the Eocene, the jury's still out on that, though it seems he may have been close if this graph is anything to go on: . Regardless of where the truth lies, however, that does not, by any means, validate McPherson's claim of 16*C warming possible as soon as 2100. To say otherwise, is unfortunately, rather fallacious.
