"There's no place on Earth that is changing faster--and no place where that change matters more--than Greenland." So said 350.org founder Bill McKibben, in a 2012 Rolling Stone magazine interview. As Earth Week 2013 draws to a close, I want to draw your attention to a unique effort to learn more about why Greenland is melting so fast--a crowd-funded research project that anyone can contribute to, which aims to answer the "burning question": How much does wildfire and industrial soot darken the ice, increasing melt? The Dark Snow Project, the first-ever Greenland expedition relying on crowd-source funding, hopes to raise $150,000 to mount a field research campaign to find out. The project is the brainchild of Dr. Jason Box, Professor at the Geological Survey of Denmark and Greenland (GEUS), and one of the world's leading experts on Greenland's glaciers. He has set up a website called darksnowproject.org to help raise the funds for the field campaign, and has raised about half of the needed amount as of mid-April.

2012: Unprecedented melting in Greenland
Watching the weather events of 2012 over Greenland made all seasoned climate watchers a little queasy. The vast ice sheet on the island holds enough water to raise global sea levels by 7.36 meters (24.15 feet) were it all to melt, and the ice melt season of 2012 gave notice that an epic melting of the Greenland Ice Sheet may be underway. According to NOAA's 2012 Arctic Report Card, the duration of melting at the surface of the ice sheet in summer 2012 was the longest since satellite observations began in 1979, and the total amount of summer melting was nearly double the previous record, set in 2010 (satellite records of melting go back to 1979.) A rare, near-ice sheet-wide surface melt event melted 97% of the surface of Greenland's ice sheet on July 11 - 12. While a similar melt event at the summit occurred 1889, but the 1889 event has no basis in the instrumental record from coastal Greenland. It's instead likely that 2012 was Greenland's warmest summer in at least 863 years, since the medieval warm period (see http://www.meltfactor.org/blog/?p=677 and http://www.meltfactor.org/blog/?p=725). The incredibly warm temperatures have been blamed on highly unusual atmospheric circulation and jet stream changes, which were also responsible for 2012's unusually wet summer weather in England. It would not be a surprise if this sort of summer began occurring more often, since temperatures on top of the Greenland Ice Sheet have been rising six times faster than the global average during the past twenty years. A May 2013 Geophysical Research Letters paper by McGrath et al., "Recent warming at Summit, Greenland: Global context and implications", concluded that by 2025, there is a 50% chance of ice sheet-wide melt events happening annually. The ice sheet reached its darkest value on record in 2012. The darkened surface was due to below average summer snow, soot particles from pollution and forest fires, and record melting. A darker ice sheet absorbs more solar energy, in a vicious cycle that raises temperatures, melts more ice, and further darkens the ice sheet. The amount of melting that was caused by soot from forest fires is important to know, since global warming is likely to increase the amount of forest fires in coming decades. However, the amount of forest fire soot landing on the Greenland Ice Sheet is almost completely unknown, which is why Dr. Box is determined to find out, via the Dark Snow Project.

Greenland causing 25% of global sea level rise
In a landmark study published in November 2012 in Science, 47 researchers from 26 laboratories reported that the amount of ice being lost from Greenland and Antarctica has tripled since the 1990s, with Greenland contributing more than twice as much to global sea level rise than Antarctica. The study, "A Reconciled Estimate of Ice-Sheet Mass Balance", found that the two ice sheets were responsible for 20% of the global sea level rise of 3.1 mm/year during the 20-year period 1992 - 2011. The remainder of the rise was due to expansion of the water due to heating of the oceans, melting of mountain glaciers, and unsustainable pumping of ground water. Said co-author Erik Ivins of NASA's Jet Propulsion Laboratory, "The pace of ice loss from Greenland is extraordinary, with nearly a five-fold increase since the mid-1990s." As of 2011, Greenland's contribution to global sea level rise on its own had risen to 20 - 25%, according to an international research group led by the GFZ German Research Centre for Geosciences, in an article published in Earth and Planetary Science Letters on 1 June 2012. If the current exponential ice loss trends continue for the next ten years, Greenland's contribution to sea level rise will double to 1.4 mm/yr by 2022, the researchers said. Many sea level rise researchers expect global sea level to rise by about 1 meter (3.3 feet) by 2100. During the 20th century, global sea level rise was about 0.18 meters (7 inches.)


Figure 3. Monthly smoothed (purple) and unsmoothed (blue) values of the total mass lost from the Greenland Ice Sheet (in Gigatons, Gt) from measurements by the GRACE satellites between March 2002-September 2012. An approximate equivalent global sea level rise figure is on the right axis. Note that the decline in ice mass lost from Greenland is not a straight line--it is exponential, meaning that more ice loss is lost each year than in the previous year. Image credit: 2012 Arctic Report Card.

Will Antarctica be more important than Greenland for sea level rise?
Although melting from Greenland is currently raising global sea level by about a factor of two more than Antarctica melting is, that situation may change later this century. A 2013 study by Dahl-Jensen et al. looked at a new ice core drilled from the bottom-most depths of the Greenland Ice Sheet. The core suggests that the ice in Greenland may have partially survived the warm Eemian period before the Ice Age, approximately 118,000 - 126,000 years ago, when Greenland temperatures were 5- 8°C warmer than present-day temperatures. Global sea level during the Eemian was 4 - 8 meters (13 - 26 ft) higher than the present sea level, and the scientists estimated that melting from Greenland was responsible for 2 meters (6.6 ft) of this sea level rise. This implies that Antarctica was responsible for 50 - 75% of global sea level rise during the Eemian, and thus we might expect Antarctica to take over as the dominant source of sea level rise later this century, when global temperatures may to rise to levels similar to those experienced during the Eemian.

Dr. Jason Box's blog on Greenland and the Dark Snow Project is at http://www.meltfactor.org.

The http://www.greenlandmelting.com/ website looks like a great resource for following this year's melt progression in Greenland.


Video 1. Glaciologist Dr. Jason Box and 350.org founder Bill McKibben plug the Darksnow project in this January 2013 video by Peter Sinclair. There's some impressive footage of the record Greenland snow melt of summer 2012 sweeping away a 20-ton tractor that was attempting to repair a bridge washed out by the raging Watson River on July 11, 2012 in Kangerlussauaq, Greenland. The driver escaped unharmed.

Support the Dark Snow Project
One of Dr. Box's collaborators, photographer James Balog, who created the amazing time-lapse Greenland glacier footage in the fantastic 2012 "Chasing Ice" movie, puts it like this: "Working in Greenland these past years has left me with a profound feeling of being in the middle of a decisive historic moment--the kind of moment, at least in geologic terms, that marks the grand tidal changes of history." On that note, I encourage you all to support the Dark Snow Project. Have a great weekend, everyone!

Dark Snow Project Expedition Plan 2013
Prepare and gather science equipment including a field spectrometer, snow and ice coring device, and snow metrics kit.

Travel to Iqualuit, on Baffin Island, Nunavut from home locales in California, Ohio, Michigan, Vermont and rendezvous with Dash-6 "Twin Otter" ski-equipped airplane and flight crew.

Organize cold weather survival kit.

Ferry team from Iqualuit to Kangerlussuaq, Greenland.

Fly to and land at sampling sites high on the inland ice sheet.

At each site collect snow samples from a snow pit and obtain snow cores to a minimum depth of the previous year's snow surface, and record snow properties.

Transport of team and snow samples to Greenland's capital Nuuk, where the team will rest after hustling at field sites.

Return to Iqualuit, then to respective home locales to start the data analysis and reporting phase of campaign.

You know, it was also Einstein who said, "Not all that things that seem insane really are". ;-)

Now, because you "only spend a fraction of your time here", I'll repeat what I've said perhaps a hundred times: few of us are here to try to sway those who lack the intellectual honesty to accept established scientific fact. We're simply not. If someone wants to go through life encased in a sphere of ignorance and self-delusion, we can only pity them and wish them the best. Wasting any further resources trying to attempt them is obviously pointless. But we will do what we have to do to ensure that the seeds of ignorance they're so desperately intent on sowing find no purchase. We know that such weed-pulling might upset some of the forum's concern trolls, but, well, that's how we work.

So now I gotta ask: how did you amass more than 10,000 comments while spending "only a fraction of your time" here? ;-)

99/100 is still a fraction you know... ;P

You are correct in noting that I have amassed over ten thousand posts over the nearly seven years that I have been a member of Weather Underground, which would equate to approximately four posts per day over the period of my membership. A good deal of posting for sure, but not obscene, especially with many of the posts occurring during times of active and interesting weather. Meteorology is my passion, after all.

Now, as for the main point, I also have the same desire as you to prevent the spread of ignorance throughout Weather Underground and points beyond, and with little to no concern how the trolls feel about it. However, we clearly have different ideas on how best to proceed with said task, and at this point, it appears that our ideas will remain at odds with each other, which at this point is perfectly fine by me. Diversity makes the world go 'round and the world would certainly be a pretty boring place without differing ideas. In terms of science, there is of course empirically correct and incorrect, but with more abstract concepts such as ideas, there is more grey area since ideas are often much harder to prove. And this appears to be where we find ourselves.

When I first joined Weather Underground, I was a much younger hotshot who thought he knew it all when it comes to meteorology. My time on this website has very much humbled me and taught me so much, arguably more than I have learned in my meteorology-specific college courses. And not just about meteorology/climatology either. Through every exchange, whether on this website or not, I always make it a point to learn something new, and this has served me very well throughout my brief existence thus far. This exchange is no different, and I hope you have continued to learn from this exchange as well. It's been a good one my tri-toned ice cream friend! ;)

That's a common concern for me regarding most people.

Last years rainy season was defiantly above average, at least for my area. Loved it - 2010 and 2011 were completely pathetic. Some reason El Nino, or warm-neutral years, seem to have better rainy seasons in my area (2006, 2009, and 2012).


The old tale in southern Florida,was that if it didn't rain in May, there would be a hurricane.

If we were speaking of only "a few close minded ones", I think I might tend to agree with you. But, alas, there are more than a few, and close-mindedness is the least of their character flaws. There's willful ignorance, rigid ideological thinking, rabid anti-intellectualism, a deeply-rooted mistrust of science and scientists, poor facility with English, limited depth or dimensionality of thought, and so on, and so forth.

That's quite a basketful, if you ask me. And allowing those thus afflicted to have free reign of the room never really seems to accomplish much... ;-)


You know, I get frustrated with anti-intellectualism myself, and it is very complex as how people end up that way. Regardless though, I prefer mercy over cutting down others for their intelligence or lack there of, not everyone will embrace science, and whether they do or not shouldn't effect the condition of how we treat them.

Intellectualism also may not be as supreme to human progress as one might think either; if intellectuals forget the value of other things beyond just calculation and the scientific process, it leads to cold achievement of the intensive utilitarianism. We must seek balance in our thoughts and lifestyles.

Well El Nino years are known for not just being above average rain in Florida during the dry season, but in general they are known for bringing rainy weather year round so what you noticed makes sense, El Nino effectively means no apparent dry season, just a lot of rain throughout the year.

La Nina on the other hand is know for horrible droughts in Florida during the dry season. Typically there is not supposed to be any link to drier or wetter rainy seasons when it comes to La Nina, they can go either way. La Nina years do typically lead to a lot less yearly rainfall in comparison to El Nino years on average.

At the same time, what has confronting said group of people accomplished? Perhaps I'm incorrect when I say this for I only spend a fraction of my time here, but it does not appear that your guns-blazing approach in the name of science has turned the tables whatsoever regarding the mis-informed and closed-minded. If I'm not mistaken, it was Albert Einstein who defined insanity as the repetition of the same thing while expecting different results. Almost every time I visit Weather Underground, the same confrontations and arguments rage on and on, and yet the results never change. Perhaps a different ideology for handling the issue will yield better results, but as you mentioned, perhaps not. This is for sure though: you don't know until you give it a try. The status quo cannot carry on indefinitely.

I doubt if any of these esteemed people mentioned in this article will provide any satellite data from before 1492.

These people are looking at a sliver of data that they should be looking at...data, that doesn't exist

I assure you that inconsistent rainy season observation of yours is quite local. Looking at the records yes, unfortunately parts of SW was rather lacking compared to average. However most of Florida actually saw a very soggy rainy season with at or above normal rainfall in most other spots in the state. In fact, the water management in Central Florida last year mentioned that ground water finally returned to normal last fall in nearly 10 years due to widespread heavy rains of 40 to 50 inches just during the rainy season period with many rain gauges actually a bit above normal during the period.

State wide though, outside of the rainy season has been wretched dry the last few years or so. This can be thanked to mostly La Nina dominated or Neutral leaning La Nina dominated over the past few years.

YB, I've heard locals here in SW Florida talking about past wet springs leading into active hurricane seasons. Whether one has anything to do with the other I can't say for sure yet, but I sure hated the Crown Weather forecast someone posted a day or two ago showing SW FL with a 90-95% chance of a hurricane this year....

On the plus side, this is my 4th spring here since moving to Florida, and it's been just plain awesome to for once have some real rainfall here in April - the month that's typically our driest. I'm hoping for an early start and long length to our rainy season. The last 2 rainy seasons in particular were, for us, inconsistent and relatively short-lived, and I can't help but think that the persistent warm, stable air aloft that covered much of the tropical Atlantic had something to do with it.

Thanks for asking some great questions; I hope they will generate some discussion!

Personally, I've reduced my carbon footprint and purchase carbon offsets for what I can't reasonably avoid.

I try to learn what I can about how we can cut our carbon fuel use and pass that information on to others.

I try to educate myself about how the climate is now changing and pass that information on to others.

I write my elected officials and ask them to work through the legislative process to reduce greenhouse gas emissions.

Sea breezes, and other boundaries show up on radar when they are well defined. Moisture and instability are lacking over the state today along with some capping, so rainfall will be hard to come by, anything that does develop will be short lived and isolated.

The Indian monsoon circulation will begin to stir soon. The CFS says it will be stronger than normal in mid-late May. There is research that suggests that the health of the Indian monsoon and African easterly waves are related.

Thanks. Correlation is not causation, and it looks like only Florida was well above normal. But it's interesting, nevertheless.

You must have some memory to be able to access obscure information like that.


I have weird things memorized like the list of top ACE seasons and all years that had 3+ U.S. hurricane landfalls. It helps me look up patterns quickly.
