AvantHiatus Posted June 15, 2015 Share Posted June 15, 2015 That's out of line. Don't stoke the flames. This is just a personal disagreement between two people. I've been trolled on this forum personally and it's against forum policy to make a second account, much less make a second account to troll people. Sometimes it's super-obvious, like the account has only 1 troll post and was created a day ago. Yet nothing is ever done about it. It's respectable that ORH is open-minded and a lenient moderator. Perhaps I should have used different wording here. Link to comment Share on other sites More sharing options...
WinterWxLuvr Posted June 16, 2015 Share Posted June 16, 2015 I don't take lectures from an incompetent moderator. You should be able to figure it out ORH. Here's a thought. Post your credentials and we can compare them to ORH. Then we can get a better handle on who the incompetent one is. Link to comment Share on other sites More sharing options...
AvantHiatus Posted June 16, 2015 Share Posted June 16, 2015 Friv/Global, I really do enjoy reading/following this forum, and your contributions are surely up there with the best. Just please try not to use the extreme's when you see things emerging, as they often get muted to things way less than your tone suggests. A one day run that shows "incredible" warmth...often doesn't verify and it detracts from the quality of the information that you offer. Keep up the good work and just think about it. Nut It is what it is, TGW doesn't control the weather. Link to comment Share on other sites More sharing options...
AvantHiatus Posted June 16, 2015 Share Posted June 16, 2015 Lockstep with global temperatures in some years like 2010 and 2007 but the connection is weak. Otherwise the overall contour resembles the hiatus. Bluewave, you should probably narrow your domain to May - September. This is the time when arctic temperatures are most impactful for the ice, albeit polar amplification will show up in all seasons and more strongly during the winter. The 0.1C rise was based on the 2013-2014 cold summer era ending and never coming back. You will have intra-annual variability but arctic temperatures should stairstep every 3 years or so from now on.

AvantHiatus Posted June 16, 2015 Share Posted June 16, 2015 The summer temperatures are contingent on the melt season. As you can see, the temps dropped off after the record 2012 season an were comparable the last two years to the early 2000's. TEMP.png A larger drop occured in the early 1990s, we should still expect Arctic warming to continue in earnest. Link to comment Share on other sites More sharing options...

We should expect only regional effects from this. This is a nasty brew for sure with some unknown consequences, most likely not very not distant from James Hansen's vision of continent-wide superstorms.

I want to believe you. The only example I can think of is this interview from 2009 where he mentions the topic of tipping points. Otherwise, his warnings are usually vague and far out into the future. In other words, no body really knows if he was right, even if they claim to know, which goes back to having a false perception of the climate. No doubt the cold spell in the US had an effect on maintaining people's opinions despite TWCs heoric efforts. In many ways he was right on the money due to 2012 and the recent occurrences in Antarctica involving the collapse of WAIS. FWIW, James Hansen probably knows more about AGW than anybody else in a hollistic sense. In the grand scheme of things, 2013-2014 does not represent the next 5 years and definitely not the next 20 years. Link to comment Share on other sites More sharing options...

That is a ridiculous assertion. These predictions made by Hanson in a 1981 paper before global warming was even an issue have proven to be quite accurate. Unfortunately we didn't make much use of them. Hansen, J., D. Johnson, A. Lacis, S. Lebedeff, P. Lee, D. Rind, and G. Russell, 1981: Climate impact of increasing atmospheric carbon dioxide. Science, 213, 957-966, doi:10.1126/science.213.4511.957. The global temperature rose 0.2°C between the middle 1960s and 1980, yielding a warming of 0.4°C in the past century. This temperature increase is consistent with the calculated effect due to measured increases of atmospheric carbon dioxide. Variations of volcanic aerosols and possibly solar luminosity appear to be primary causes of observed fluctuations about the mean trend of increasing temperature. It is shown that the anthropogenic carbon dioxide warming should emerge from the noise level of natural climate variability by the end of the century, and there is a high probability of warming in the 1980s. Potential effects on climate in the 21st century include the creation of drought-prone regions in North America and central Asia as part of a shifting of climatic zones, erosion of the West Antarctic ice sheet with a consequent worldwide rise in sea level, and opening of the fabled Northwest Passage.

These predictions made by Hanson in a 1981 paper before global warming was even an issue have proven to be quite accurate. Unfortunately we didn't make much use of them. Hansen's peer reviewed stuff is mostly good. (as are most other scientist's peer reviewed work) It is his public activism and his hyperbole in outlets such as senate testimony or just to the media in general are what has been counterproductive IMHO. An example was his 1986 testimony where he warned of a 2 to 4 degree rise in temps in the next 20 years. Or his more recent claims of 5-10 meter SLR by 2100 (even suggesting up to 25m to senate in 2007)...while the latter isn't verifiable yet of course, it is an outlandish claim given the rest of the literature. His account of NYC's west side highway being underwater due to SLR by 2030. His predictions for strong or super el Ninos (one was as recently as 2011 when everyone else was predicting a La Nina). All of that is stuff the public/media hears and latches onto. It's unfortunate it has to be that way, but only climate hobbyists and other scientists actually read the literature. The rest only read the media headlines or the hyperbole directly from the scientist's mouth. Hansen has been an activist and while I don't doubt his sincerity in his cause, it does create a less than objective image for the science he represents. People like us who follow climate rigorously can just say "well ignore that junk and focus on the literature"....but that can't be said of most of the population. I don't blame all of it on Hansen of course...I think the media has been the worst offender. Link to comment Share on other sites More sharing options...
AvantHiatus Posted June 18, 2015 Share Posted June 18, 2015 5-10 meter SLR It's still barely in the realm of possibility. That would be an insane acceleration tho and that kind of meltwater injection would definitely shut down ocean circulations and end civilization across the board. It also requires that we stay on business as usual indefinitely which is unlikely. The CO2 atmospheric level would be something insane like 600ppm by 2080.

I wasn't familiar with Hanson's testimony so I googled and came up with the document linked below based on his 2007 testimony. Its not nearly as bad as you suggest. Its very scientific in tone - unlikely to cause a reaction in anyone except those already of a skeptical bent. His temperature projections are close to consensus. Some of his effect projections are high end but I wouldn't call them outlandish. He says SLR could be 2 meters in 100 years due to mainly to WAIS.. At the time this was quite aggressive.Since then however much more has been published on ice sheet instability and WAIS in particular. His projection is still high end but it is moving into the range of possible outcomes. Blaming Hanson for climate denial/skepticism is a big exaggeration. I discuss climate with many skeptics. They mainly stick close to the denier talking points:: the data is fudged, the scientists are in cahoots to get grant money, temperatures haven't increased in 18 years, climate has always varied etc..

While saying Hansen is to blame is surely hyperbolic in it's own right, exonerating failed alarmist predictions is also not completely accurate IMHO. You are still trying to tie in his peer reviewed official work, which is generally good. If you read most of his testimonies they are pretty good too...but again, where do you think the media and headliners get those 2-4C predictions from 1986 or the 10 meter SLR? They get it from his testimony. His west side highway under water while talking to the author of a book. That is all stuff the media grabs and the public hears about. As mentioned above, I think the media is more to blame than hyperbole from Hansen.

I can see where it would be misleading if snippets were taken out of context. These posts stimulated me to read portions of his 1981 paper. While portions are dated and missed the mark, many of his 1981 predictions are very accurate. His discussion of WAIS could have been written today but was way ahead of his time. It would be the height of irony if his warning of a WAIS collapse turns out to be correct - and yet leads to inaction per the theory outlined above Link to comment Share on other sites More sharing options...
