Tom Curtis, true, that is a good point. Still, I feel my point is valid,. People like to idenify with a group, it is a good feeling to be a part of something larger than oneself and for many people that can be a more powerful driver than cold, dry facts.
To be clear, I'm not suggesting that these people cannot be reached, or even convinced to change their minds. I only suggest that facts, or as Digby puts it, evidence, presented alone, is not the most effective way to reach them.
There are many other ways to reach someone, and different personality styles wil respond to different methods. Advertisers understand this well and will produce ads that reach us in different ways on different levels. Naratives, humor, and appeals to emotional, moral and social resonance are just a few. Of course facts should be included as well, but they need to be presented in the proper context to be widely convincing.
Politicians are naturally skilled at making these kinds of convincing arguments, while the typical scientifically oriented personality is not. There are notable exceptions; Neil DeGrasse Tyson and Bill Nye for instance. But I think this generally explains why so many people find the arguments of politicians more convincing than those of scientists, even though the scientists may have a far superior backing of evidence.

Tom Curtis at 20:27 PM on 4 September 2015Northwest passage has been navigated in the past
MRoscio @6 & 7, the Manhattan was accompanied by an icebreaker, the USCGC Northwind, on its westward passage, and by another icebreaker, the USCGC Staten Island on its eastward passage. At some unspecified stage, it also had additional assistance by the CCGS Louis S. St-Laurent. This despite having been modified to itself be an icebreaker. Likewise, the Canmar Explorer II was also accompanied by an icebreaker, the CCGS Louis S. St-Laurent.
Given that multiple commercial ships and hobby craft transit the Northwest Passage every year now, without icebreaker assistance, I am not sure what your point is.

The first commercial ship to complete the Northwest Passage, in both senses, in the same year, was the US supertanker Manhattan in 1969.
The second one, as far as I know, was the drilling ship Canmar Explorer II in 1976.

BBHY @2, in defense of the aparently illogical Democrats and Republicans in that survey, there are policies I would trust some parties to impliment, but not others, even when the policy is essentially the same at a brief level of description. Not only is there much devil in the detail that can be a make or break issue on some policies, but even the detail of legislation does not cover the way in which policies are administered which can also make a difference.

Digby, for many people logic and facts are not the driver of their views on climate change.
A recent Washington Post survey found that when Donald Trump proposes a policy, Republicans love it and Democrats hate it. When President Obama proposes a policy Democrats love it and Republicans hate it. This applies even when it is the exact same policy.
Views on climate change are similar. Many people have their particular view not because of the facts and logic, but because it helps identify them as belonging to their chosen political camp. This is just human nature.
Personally I prefer facts and logic, but I beleive I may be in the minority in that regard.

I have to confess that I've not — yet — read any of the material of this course, but I have a related question that has been bothering me for some time. If it has already been answered, I beg forgiveness.
My question concerns deniers who reject the evidence for global warming. Has anyone asked them what they would consider to be "proper" evidence? For example, no more ice at the poles would surely be incontrovertible, if rather drastic; how about some intermediate situation, such as an ice-free Arctic Ocean in September? I would dearly like to know what they would put forward. It should be very entertaining.

At what level does CO2 become an asphyxiant?
Please keep in mind that even at 40,000 ppm CO2 is not harmful to humans and probably to mammals.
Also keep in mind that as water precipitates it is readily replaced by evaporation, and it appears that water vapor varies over a wide range at a given location and time....

You're talking nomenclature now: once the lingo is defined you can methodically work out the answer to the half-solved, said and specified problem.

The terminology used leads to gross misunderstanding. Humans do not emit the greenhouse gases that have caused irreversible rapid climate disruption and ocean warming and acidification. It is the technological systems of indusrialized civilization that has done the damage. People can only make decisions, good and bad, about what should be done to adapt to what these systems have done wrong.

Ronald, I am not quite sure what you are trying to achieve here. Climate theory says you expect temperature trends to be correlated to net forcing (with some lag), not just CO2. For an example, see Schmidt and Benestad 2009.

So does anyone predict that now citizens of these states will rise up and demand that their representatives do something about climate change...
I don't expect them to, and if they don't it is yet more proof that events themselves, even extreme and devastating events that can clearly be connected to GW, are not enough by themselves to change minds of even those directly effected by said extreme events.

I have reworked the temperature anomaly and CO2 image. The temperature anomaly uses the average of the first 30 realisations of the HadCRUT4 data. I changed the base years to 1850 - 1880. I log transformed the CO2 and regressed it to the temperature anomaly. Correlation is 0.796. With more work, the CO2 concentrations can be alligned with the temperature anomaly lines.

Ryland @1&7.
I'm not sure what your point is. I assume you are aware that your referenced Guardian article dates to 2009. Mind, it doesn't take much to get the papers to pop an angy editorial at the Met Office, as this Met press release from April this year shows.
If you look for real criticism of 2015 Met Office summer forecast stories, there was an item in the Exeter Express & Echo yesterday (the Met Office's Hadley Centre is in Exeter) complaining that the forecast average rainfall didn't match the 175% average that actually fell. (The whimps. Bournemouth got 230% in August, an August record, but not a word of complaint about weather forecasting. The sun always shines in Bournemouth!!!)
More seriously, there is chatter that the climate deniers of the new UK all-Tory government are doing their best to put the boot in the Met Office good and proper. If they can't get the CRU direct, the Met Office is a good alternative. Aren't they both jointly to blame for HadCRUT?
So we find the Gentlemen Who Prefer Fantasy re-blogging the ExeterE&E story and there are more viscious stories running round the rightist press which (with a few additional anachronistic stories for good measure) have been cut&pasted by the Gentlemen then nailed to the petrol pump on planet Wattsupia by the fair hand of Willard Watts himself.
The serious point, mentioned by the ExeterE&E, (with more coverage here) is the Met Office losing the BBC contract under rather odd circumstances.

One Planet Only Forever at 00:34 AM on 4 September 2015Citi report: slowing global warming would save tens of trillions of dollars
"Too big to fail" is a misleading term. That term is used to prolong irresponsible unsustainable gambles just because they have become very popular and profitable and to reward and protect those who obtained wealth and power from the unacceptable success of such pursuits.
The losses that should be faced by investors and employees and consumers whose perception of success are based on getting away with the understandably unacceptable gambles will clearly have to be forced on the current system. It is clear that the current system encourages leadership that will defend and promote the least acceptable economic activity that can be gotten away with.
What is needed is leadership that focuses on the constant improvement of the understanding of everything that is going on. And the required type of leadership would apply that understanding to encourage and promote development toward a lasting better future for all life on this amazing planet (something I contend is the only viable future for humanity on this or any other planet). That action by responsible leaders would include forcing changes of what has been developed. And that would include ensuring that those who hoped to benefit from unacceptable economic development wold suffer the losses they deserve in spite of the ability of misleading marketing to create perceptions of popular support for understandably unacceptable economic gambles.
The future of humanity clearly depends on the development of ways to ensure the success of that type of leadership in business and politics (to the detriment of unacceptable gamblers who desire short term personal benefit any way it can be gotten away with). Without such leadership the future is guaranteed to be more inhumane and immoral as there is more and fiercer 'competition to benefit the most from diminishing limited opportunities to get away with unacceptable actions'.
Hopefully, that type of leadership will develop in time to keep undeserved wealth and power from remaining in the hands of people who have clearly not responsibly limited their actions based on the developing understanding of what is going on. That leadership will admittedly be regionally unpopular to different degrees. So the requirement will become global leadership collectively pressuring and penalizing unacceptable regional and business leadership in the hopes that such actions will 'change the minds of those who have decided to try to get the most personal gain as quickly as possible in the least acceptable way they think they can get away with'.
And responsible global leadership clearly must not try to protect or defend undeserved perceptions of prosperity and wealth in already developed regions that deliberately continued to burn fossil fuels to obtain more competitive trade advantages or places that encouraged the increased export of fossil fuels for burning, particularly the export or burning of coal, oil sands or pet-coke (the worse than coal waste product from upgrading heavy oils like oil sands bitumen).

Fairoaken,
This article on the extraordinary hurricane season in the Central Pacific is relevant. The predictions were that over the long term (longer than 10 years) strong hurricanes would increase. This year the Northern Hemisphere has set a record for most hurricane activity, it is just not in your back yard. Hawaii has been threatened three times. Until recently Hawaii was considered to be out of the Hurricane zone. AGW has put Hawaii at risk. Sandy was also a month after the normal end of Hurricane season in the NorthEast USA. Hurricanes are occasional occurances and a lot of chance is involved in exactly where they occur.. If hurricanes are increasing world wide it is only a matter of time before you get hit.
In addition to Hurricane Sandy, mentioned above, you did not notice the 2 category 5 hurricanes that hit central America in 2007.

Thanks Tristan. The shape of the CO2 curve did not change but the scale will. Initially, I use Excel regression and the correlation was 0.797 and assumed that I could use that. I log transformed the CO2 concentration and used repeated the regression in Excel. The correlation between CO2 and Temperature Anomaly went down to 0.796. I can use the heavy hand approach to rescaling the CO2 by using white numbers and manually placing the revised values in place of the ones that are there now. The major item I was trying to show is to have the first 30 years of CO2 align with the 0 for temperature anomaly.

The forecasts to which I referred were made by the UK Met Office as reported in the Guardian "This year was to be different, we were told. A "barbecue summer" – from no less an authority than the Met Office itself."
"Yesterday, though, the Met Office conceded what Britons have seen with their own eyes over the last few weeks: apart from a fortnight in June, the summer has been more soggy than sizzling. And it's not likely to get much better in August, a prediction that will disappoint, if not entirely surprise" (http://www.theguardian.com/uk/2009/jul/29/summer-weather-forecast-rain-holiday)
These would appear to be credible forecasts from experienced meteorologists

An article very pertinent to the remarks of ryland and Fairoakien:
"Increasingly, projections about hurricanes or winter storm are being posted by a range of people and often it is hard to distinguish between a credible forecast by an experienced meteorologist or the opinion of a hobbyist that is getting ready for the high school prom. Such opinions can create conflict and confusion in potentially life-threatening situations."

So you have much smaller systems that burn (yes, that produces CO2) fractions not useful for plastic to power the cracking (and cogenerate power while at it). If this is the only CO2 from FF in use, then I rather suspect the planet will cope ok (and certainly a lot better than current usage). The refining process would be different when the target is not to produce as much transport fuels (ie less cracking) as possible. Tuning for petrochemical production would be different.

Katrina. 10 years we were told because of global warming the Gulf and the Atlantic Ocean are getting warmer. I agree.
Then the global warmimg forecasters/modelers said that the Gulf would suffer more and more violent hurricanes because of the warming.
Well that hasn't happened. No category 4 or 5 hurricanes ahve hit the east/South coasts in the 10 years. Florida has had the quietest 10 years of hurricanes.
in fact the drought in Texas and Oklahoma can be attributed to the lack of good tropical storms coming off the Gulf.

Here is an alternative method of displaying two parameters on a single image. This was generated in PowerPoint and is two separate data sets. For the CO2 concentrations, I selected the Y axis to be displayed at the maximum value. I adjusted the maximum and minimum CO2 concentrations to coincide with the temperature that correlates with the regression values for the minimum and maximum temperature values.

One Planet Only Forever at 00:27 AM on 3 September 2015Citi report: slowing global warming would save tens of trillions of dollars
The concept of "Moral Hazard" is an interesting concept.
The reality is that many economists fail to consider that some humans have no morals. And they are encouraged to ignore that reality because admitting it leads to the obvious understanding that popularity and profitability are poor measures of acceptability. It also leads to the understanding that a system based on people being as free as possible to do as they please will degenerate as those who care less about the consequences of how they benefit clearly become the 'bigger winners'.
And rules alone are not an answer. Sports provides the best way of describing the behaviour. In a game without referees and meanigful penalties the result will be cheaters winning by deliberately doing things they understand are unacceptable. And the amount of unacceptable behaviour will increase with the perceived potential reward for getting away with the unacceptable behaviour (and immediate opportunity to benefit overrules any potential negative consequences in many risk taking evaluations). And in most sports new rules and methods of monitoring need to be developed as new ways of being unacceptable develop. And inspiet of the rules some people will try to argue against the application of the rule to something they did.
The economic system is similar to sport except that every aspect of it is subject to bigger reward for anyone who can get away with any form of less acceptable behaviour.
So the obvious conclusion is: Until humanity develops to the point where every human seriously pursues the best understanding of what is going on and diligently and responsibly strives to have all of their actions be leading toward the development of a lasting better future for all life on this amaing planet, there needs to be lots of effort put into constantly improving the effective restriction of what is allowed to be gotten away with in economic (and political) activity.
Acknowledging that leads to the understanding that much of the currently developed economic activity and perceptions of wealth and prosperity are an illusion, a very damaging reality poorly understood by many that some very wealthy powerful people fight to expand their personal benefit in. It is a system where the developed wealth and power will fight against admitting they do not deserve the perceptions they have gotten used to, the perceptions that were irresponsibly allowed to develop.
It is definitely a challenge to develop broad acceptance of that understanding of what is going on in a global society that has most people immersed in mass-marketing consumption based efforts to link and limit perceptions of acceptability, merit and value to perceptions of popularity and profitability which can be completely ammoral and likely be immoral.
The required action to address the developed better understanding of what is going on because of the burning of fossil fuels is challenged because it raises the awareness and understanding of the unacceptability of more developed economic activity than just the burning of fossil fuels.
Many books have written about this including Rachel Carson's "Silent Spring", Paul Hawken's "The Ecology of Commmerce", and most pointedly Naomi Klein's "This Changes Everything".
The failure of the current socio-economic-political games to develop lasting improvements of conditions for all of humanity is not a new understanding. What seems to be new are the simplistic claims that the system and what has developed are not the problem, the growth of human population is all that needs to be addressed.
Obviously what needs to be limited is the potential for success by humans who try to benefit or win by getting away with deliberately not caring to limit their actions based on the possible to understand unacceptability of how they try to benefit. It would be nice if all such humans would responsibly and considerately change their mind if given enough information presented in an appealing way, but that is clearly an unrealistic expectation.
Therefore, the required action is ensuring that the only actions permitted to succeed in the socio-economic-political games are actions that will promote and develop virtually eternally lasting activity all of humanity can benefit from (that will not be as popular or profitable as what might be able to be gotten away with). That will mean limiting the total human impact on renewables to the rate of renewing (that will also not be as popular or profitable as what might be able to be gotten away with). That does imply addressing the total human population number, but only after excessive consumption and impact by the highest impacting and consuming humans has been restricted (which will definitely not be popular or as profitable as what has been able to be developed).
This need is nothing new. The thoughts about how to limit the success of the unacceptable economic pursuers among us have even been the basis for religious edicts like bans on 'usury' many centuries ago. And before Rachel Carson, writers like Shakespeare and Dickens were trying to get the message out.

They actually hit $0.99 briefly on July 28th. That said, while I've been noting the collapse of coal in the United States for several years now... it is not yet a global phenomenon. China and India have easy access to cheap coal... but are not as well situated for natural gas, wind, or solar. As wind and solar costs continue to decline that is changing, but coal seems like it is going to continue to be a major player in those and other regions for years.
Hopefully, they will look at studies like the one above and consider costs other than just the nominal price. When total costs are accounted for wind and solar are already cheaper than any of the fossil fuels nearly everywhere. China already seems to be reaching that conclusion due to their massive pollution problems, and India has recently shown signs of changing course too.

If it is this can't be good can it?? If the myth being addressed is that the problem is not bad then can some mention of this be made in a revision of the answer to this skeptical questioning of the science.
I don't want to push the point and it's not my site but it would seem appropriate is all I'm saying.
I'm just saying it gives me the chills to hear that this could be a reality: that there is indeed no money for Glacier Research at a time when we are seeing funny rates of change to other indicators of climate change, namely the sea ice in the Arctic.
Isn't science all about corroboration?

It is ironical that the arguments presented are based on intangible future financial costs. The reality is tangible natural physical resources are being used up for the operations of industrial civilization with the unintended consequence of causing climate disruption and ocean warming and acidification. The term 'renewable energy' refers to alternative infrastructure that can only be a small, worthwhile alternative to fossil fuels in some circumstances. They cannot provide alternative liquid fules for land, sea and air transports. A realistic evaluation of what should be done would take this reality into account because the actual future financial costs will be very dependent on this reality.
Moderator Response:[RH] You're going to have to substantiate the statement, "The term 'renewable energy' refers to alternative infrastructure that can only be a small" or retract it in order to continue with this thread.

As the first day of Autumn arrives it is perhaps pertinent to note that despite the single "hottest day ever" on July 1 (transiently at Heathrow Airport) the forecast of a "BBQ summer" so loudly trumpeted by our wonderful Met Office, failed miserably (for us all) to arrive. I'm sure that when the records are reviewed and the appropriate adustments made, 2015 will be, globally at least, exceedingly warm but please can we be spared the never ending series of dud forecasts about snow and cold and sun and heat from the error prone BoM?

ronald myers at 08:42 AM on 2 September 2015Tracking the 2C Limit - July 2015
Like Tom Curtis (Comment 11) indicates the use of a reconstructed temperature existing prior to the industrial revolution and the expansion using fossil fuels should be the goal. If it is believed that only data collected with temperature measurements are considered adequate, then the use of the HadCRUT4 data should be considered to extend the baseline back by thirty years. But as I believe Rob Honeycitt (Comment 29) and Tom Curtis (Comment 30) infer but do not state, one could use the large number of temperature estimates which characterize not only the pre industrial temperatures but also estimates of the normal variability and rate of change.
I have extracted the first thirty of the one hundred Realisation's in the HadCRUT4 Gridded data: ensemble members data set. I averaged the monthly ensemble members to arrive at a monthly value. Then I averaged the 30 years from 1880 to 1910 and the 30 years from 1850 to 1880. The earlier period was warmer by only 0.07 C. While I used the arethmetic mean verses Hadley use of the median value, the difference is not significant since the data are nearly normally distributed (based on a skewness and kurtosis of less than 0.1).
Next, I downloaded the data used by 2010 Frank et.al. for their January Nature paper. I adjusted the baseline of that data to both a 1880 to 1910 timespan and a 1850 to 1880 timespan. I then averaged the temperature anomalies from year 1000 to 1800. The average anomaly for the 1800 pre industrial years was only 0.03 C different from the 1850 to 1880 period and only 0.06 C different from the later period.

moreover at 06:14 AM on 2 September 2015Citi report: slowing global warming would save tens of trillions of dollars
Rob, I agree it was a missing moral hazard and you described the mechanism well. An excellent account of the mortgage crisis comes from economics prof Richard Wolff: "Housing Crisis, System Failure"
The massive decline of profitablility of the coal industry has already begun with the remaining players posting hundreds of millions of losses quarter after quarter.
Tuesday 8/4/15 #2 US coal company Arch Coal resorted to a a 10:1 reverse stock split that went into effect yesterday ( so their stock that had been worth about 17 cents/share went up (about) 10 fold in value and all of a sudden was worth about $1.60 per share. Otherwise they would have been kicked off the NYSE for being below $1 per share for too long.
Alpha Natural (ANR) was taken off the NYSE and filed for bankruptcy on Monday 8/3/15.
# 1 coal company Peabody at some point dipped to $1.10 per share - you get the picture.

Rob Honeycutt at 03:16 AM on 2 September 2015Citi report: slowing global warming would save tens of trillions of dollars
bvangerven... I'm not perfectly sure, but I think it's the reverse. There was a missing moral hazard in the banking crisis because, in the end, the lender banks were able to transfer the risk of their loans to the capital markets. And when those investment banks took on those consolidated loan packages and converted them into securities, they had no idea of their intrinsic value, but that also didn't matter to them because in a crash the taxpayer ends up having to bail them out.
There was a lack of moral hazard permiating the entire home loan industry when the banks operate in a way that they have no risk. It didn't matter to them because they're so large and so important to the economy of the nation, the government can't allow them to fail.
The risk in the FF industry, as I understand it, has to do with the fact that the valuation of FF companies is buoyed by the idea that they can continue to explore and extract reserves. The reality is, they can't continue to extract those assets and those assets are going to have to stay in the ground. So there is "wasted capital" in terms of exploring for reserves that ultimately can't be extracted that, in turn, become "stranded assets."
See Carbon Trackers: Unburnable carbon 2013: Wasted capital and stranded assets report.

@scaddenp (#69): Agreed, up to a point. Remember that only a fraction of petroleum is suitable as feedstock for plastics, and that processes such as cracking take a lot of energy. Doing something other than burning the non-feedstock fraction will take considerable discipline, or incentives.

braintic @78.
The "one match every 3½ years not 20 years" concerns the one match in the room to raise the CO2 level.
A comparison without getting too confusing. I am saying the room is bigger than your estimate (your room 30% the size of mine) and my match estimate works out smaller (my carbon content estimate for a standard sized matchstick 0.055g(C) to your 0.093g(C)).
This still leaves the size of matchstick that Giaever is working to. If he estimates the air in the room and atmosphere correctly, his match would be very big indeed at 0.3g(C), even bigger than a large kitchen match (0.34g per item, so carbon content 0.17g(C) each).
As for your strike rate, that would increase with the smaller matches from 1.3 matches/person/minute to 2.3. But note that only represents the carbon from car exhaust pipes that remains in the atmosphere. If this mass striking of matches is carried out in the open air, much of the released carbon would be absorbed by oceans and biosphere. We would have to strike 5 matches/person/minute to achieve the same rate of carbon release that car exhaust pipes do.

(From wikipedia:) “In economics, moral hazard occurs when one person takes more risks because someone else bears the burden of those risks. A moral hazard may occur where the actions of one party may change to the detriment of another after a financial transaction has taken place.”
The mortgage crisis of 2007 was caused by moral hazard.
The same mechanism is now at work in the fossil fuel industry: although the potential damage in a business as usual scenario is enormous, it is not the fossil fuel industry that will bear the consequences.
Therefore I am strongly in favor of eliminating the moral hazard, as follows: make it clear to the fossil fuel industry that they WILL have to pay the bill. Either in the shape of a carbon tax that will allow society to evolve to a low carbon society, or in the shape of damage compensation. As the report from Citibank shows, in the latter case the bill will be much higher. -

I'm not sure what you are saying in your last sentence.
I didn't say "one match every 20 years".
I said one match every minute FOR 20 years.
Further, when carbon burns to give carbon dioxide, it combines with oxygen from the air, so it picks up mass. The molecular weight of carbon is 12. The molecular weight of carbon dioxide is 44, with the extra mass coming from an external source. So you have to multiply your estimated mass of carbon dioxide by 44/12.
Re the ratio of atmosphere to room size - yes I was considering volume instead of quantity of air, so that calculation would be out somewhat.

Dear bad-chess-player,
we all know property developers and how real money, not to mention big government, is made by importing more customers and guess what: providing a power base to allow it all!
It's called Jevons Paradox and you sell it!!

There are additional factors fueling the opposition to doing what the constantly improving understanding of things indicates needs to be done.
There are many consumers who perceive themselves to be prosperous because of the jobs they can have and the energy and personal benefit they can get cheap as long as they defend the developments that have been gotten away with by "the group of wealthy people who have clearly understood the unacceptability of their pursuits for at least the past 25 years".
As a resident of Alberta, Canada, I am very familiar with the push for perceptions of prosperity through the expansion of the rate of extraction and sale of fossil fuels. The oil and gas and coal were pushed out through the 1990s. As the conventional oil and gas was depleted it was realized that they had to move fast to benefit from the burning of the oil sands, moving it out quickly to be burned by others.
Popularity and profitability can clearly be misleading measures of the merit, value and acceptability of things (or people). The misguided belief in the virtue and value of those things clearly needs to be overcome. And the misguided belief that 'everyone being freer to do as they please will develop good results' is another significant factor that needs to be changed.
The opposition to that adaptation of humanity to deal with the challenge of the impacts from the unacceptable popular pursuits of profit will always be strong. There is likely to always be a significant minority of humanity looking for ways to get away with the least acceptable (cheapest), things they can. Simple rules easily monitored and enforced are likely to be the most effective ways of dealing with that challenge.
Globally, maybe there needs to be a rapid transition to a ban on the export of fossil fuels by any nation (or region in a nation). After all, in less than 50 years that will need to be the global reality combined with the reality that nations or regions with fossil fuels won't even be allowed to burn them up internally, especially regions in currently developed nations.

Tom Curtis at 12:13 PM on 1 September 2015Tracking the 2C Limit - July 2015
CBDunkerson @34, BEST gives an Alaskan trend increase of 1.58 C from 1860-2014, and 1.08 C from 1910-2014. The trend increase from 1960, however, is 1.88 C per century. The sharp increase may be because of a cooling trend from 1860-1960, or because earlier data was obtained only from southern coastal regions and the Yukon Valley, both of which show reduced trends relative to Northern Coastal regions. (Seen clearly in the GISS 250 km trend map.)
More importantly, I don't think targets work like that. Specifically, in tropical regions, because of low annual temperature ranges and a small gap to the maximum tolerable wet-bulb temperature, small increases in temperature will be more harmfull than much larger increases in the Arctic and Sub-Arctic. Against that, the absolute threshold for melting ice is a significant factor in the Arctic in general, and Alaska in particular. Temperature increases in the Arctic that raise summer sea and/or permafrost temperatures above freezing will be far more harmful in the general context than much larger increases above that level. So, depending on latitutude and local conditions, a significant increase may have relatively little effect but once a threshold is crossed the impacts can rapidly become quite large. To complicate things further there are no doubt other thresholds (relating, for example, to the life cycle of beatles) which will also have significant effects. The upshot is that impacts will not scale simply with temperature increase, and will vary significantly from region to region, and event within a small radius based on local topology for a given level of increase.
