The record books for Greenland's climate were re-written on Tuesday, when the mercury hit 24.8°C (76.6°F) at Narsarsuaq, Greenland, on the southern coast. According to weather records researcher Maximiliano Herrera, this is the hottest temperature on record in Greenland for May, and is just 0.7°C (1.3°F) below the hottest temperature ever measured in Greenland. The previous May record was 22.4°C (72.3°F) at Kangerlussuaq (called Sondre Stormfjord in Danish) on May 31, 1991. The 25.2°C at Narsarsuaq on June 22, 1957 is the only June temperature measured in Greenland warmer than yesterday's 24.8°C reading. Wunderground's extremes page shows that the all-time warmest temperature record for Greenland is 25.5°C (77.9°F) set on July 26, 1990. The exceptional warmth this week was caused by the combination of an intense ridge of high pressure and a local foehn wind, said the Danish Meteorological Institute. The unusual May heat has extended to Scotland, which had its hottest May temperature on record on May 25 at Achnagart: 29.3°C (85°F). Greenland's Narsarsuaq has seen a string of 3 consecutive days over 70°F this week--the 3rd, 7th, and 12th warmest days there since record keeping began in 1941. The ridge of high pressure responsible is expected to stay in place several more days, bringing additional 70° days over Southern Greenland. The warm May temperatures could be setting the stage for a big Greenland melt season this summer--the International Research Institute for Climate and Society (IRI) is predicting a 50 - 60% that the southern 2/3 of Greenland will experience above-average temperatures this summer. They forecast just a 10 - 15% chance of below-average temperatures.

Why Greenland is important
If the massive icecap on Greenland were to melt, global sea level would rise 7 meters (23 ft). Temperatures in Greenland are predicted to rise 3°C by 2100, to levels similar to those present during that warm period 120,000 years ago. During that period, roughly half of the Greenland ice sheet melted, increasing sea level by 2.2 - 3.4 meters (7.2 - 11.2 ft.) However, the 2007 IPCC report expects melting of the Greenland ice sheet to occur over about a 1,000 year period, delaying much of the expected sea level rise for many centuries. While Greenland's ice isn't going to be melting completely and catastrophically flooding low-lying areas of the earth in the next few decades (sea level is only rising about 3 mm per year or 1.2 inches per decade at present), the risk later this century needs to be taken seriously. Higher sea levels will cause increased erosion, salt water intrusion, and storm surge damage in coastal areas, in addition to a loss of barrier formations such as islands, sand bars, and reefs that would normally protect coastal zones from battering by waves and wind. Additionally, coastal zones are sites of incredible economic and agricultural activity, which would also be negatively affected by higher sea levels. Currently, melting ice from Greenland is thought to cause about 0.7 mm/year of global sea level rise, which is about 20 - 25% of the global total, according to an international research group led by the GFZ German Research Centre for Geosciences, in an article published the latest issue of Earth and Planetary Science Letters, 1 June 2012. In 2007, the IPCC estimated that Greenland ice melt was responsible for only 10 - 15% of the total global sea level rise. Ice loss in Greenland is accelerating, and if current 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 increased ice loss in Greenland is being driven by a combination of warmer air temperatures, warmer ocean temperatures, and loss of Arctic sea ice. Ocean temperatures surrounding Southern Greenland have increased by 1 - 2°C since 1990 (figure at right.)

Figure 2. Monthly unsmoothed values of the total mass (in gigatons, Gt), of the Greenland ice sheet from the GRACE satellites. On the horizontal axis, each year begins on 1 January. Each small + symbol is a monthly value. Between 2003 - 2009, Greenland lost an average of 250 gigatons of ice per year. In 2011, the loss was 70% greater than that. Image credit: Arctic Report Card

Update on the 2011 Greenland melt season
According to the 2011 Arctic Report Card, it was another very warm year in Greenland in 2011, which led to substantial melting of the ice. Here are some of the highlights from the report:

1) The area and duration of melting at the surface of the Greenland ice sheet in summer 2011 were the third highest since 1979.

2) Increased surface melting and below average summer snowfall in recent years has made the icecap steadily darker. In 2011, the icecap had the lowest reflectivity (albedo) of any year since satellite measurements of reflectivity began in 2000.

3) The area of glaciers that empty into the sea continued to decrease, though at less than half the rate of the previous 10 years.

4) Total ice sheet mass loss in 2011 was 70% larger than the 2003 - 2009 average annual loss rate of -250 gigatons per year. According to satellite gravity data obtained since 2002, ice sheet mass loss is accelerating.

Sorry, the heat island issue has been studied and factored out of the temperature record.

We have to adjust the way we collect and use measurements. Otherwise the data becomes useless due to changing conditions.

We had to adjust ocean temperature records because we realized that by using the water being pumped up for engine cooling (old method) was actually slightly heated above the actual surface water temperature.

We no longer use that faulty technique and we have adjusted the historical record downward to factor out the mistake we were making.



Oh this will be coming back with a vengence

This is something that I would like to emphasize.

You want to be the most famous, celebrated and wealthy scientist alive?

Prove that the planet is not warming.

Or prove that the warming we are observing is not due to increases in greenhouse gases caused by humans burning fossil fuels.

That's what happens when an upper level low splits off or cuts off from the main jet stream. It gets trapped under ridging that comes into replace the trough dive and retrogrades back westward and stalls or meanders about until another trough dive comes in and picks up the cut off low.

Now I have to ask-- from what source are you getting your information? Urban Heat Island effects have been noted, accounted for, and discarded as the cause for the observed temperature increases for years now.

This really is like a carnival "bad argument" shooting gallery, only there's no prize to win. Darn it.

Something interesting a few weeks back in my neighborhood during the evening. Was on my bike riding in subdivision which is concrete with houses, and there is a large 4 acre or so green space just by the entrance of my subdivision. It was hot as usual but as I rode towards the green space it was like a rush of cold air hitting me, it was amazing what the open space grass did to the air temperature. In fact I went back and forth over and over from inside the subdivision to the green space to feel the massive difference in air temps it was unbelievable. This is on a micro scale, just think of the massive scale of development of cities....


Concrete and development IS a major influence with the urban heat island affect going on. This, is why we are in a warming world.

Here's how we deal with climate change.

We just write legislation that requires us to shut our eyes and what we can't see can't hurt us...

Republican lawmakers in North Carolina are circulating a bill which would limit their state agencies’ ability to calculate sea-rise levels, a proposal that one member of the state’s Coastal Resources Commission science panel has termed “bad science.”

The bill has not yet been introduced, but the language in the version being circulated would make the Division of Coastal Management the only state agency allowed to produce sea-level rise rates, and only at the request of the Coastal Resources Commission, and then only under the following conditions:

These rates shall only be determined using historical data, and these data shall be limited to the time period following the year 1900. Rates of sea-level rise may be extrapolated linearly to estimate future rates of rise but shall not include scenarios of accelerated rates of sea-level rise.

I find it neat how, on the one hand, he proclaimed that warming during the past century or so is due to a several percent per billion years increase in solar output...

...then on the other hand, pulls out a CO2 vs. temperature chart covering the entire Phanerozoic and promptly ignores that the solar output was significantly lower during the Paleozoic and Mesozoic.

Skeptical Science has this one covered, too. Short version - while right now, we need current solar output + 500ppm CO2 to have a planet with large ice caps, back in the mid-Paleozoic it took dipping below 3000ppm to grow/maintain ice caps due to decreased solar radiation.

A number of denier types moved off to a site named something like this one but underground was replaced with the 'b' word.

They apparently were so disruptive on this site that linking to or directly naming the site has been forbidden in an attempt to get back to weather, climate and science.

As for you getting hit with the troll label at this time of year, when the tropical storm season gets underway, there are some people who register under multiple new names in order to disrupt. (For some reason this site attracts a lot of immature people.)

Actually we have a far less bio diverse planet today than we did during the Cambrian period. And no, not single celled organisms either.

Anyway, here's an estimate of how much CO2 we're emitting, how much gets absorbed by the Amazon Rainforest and projections of where we're going.
Link Article 1a
Accelerated Global Warming and Atmospheric CO2 Emissions

An assessment of the likely increase of CO2 in the atmosphere due to climate change and if the Amazon Rainforest ceases to be a CO2 sink.
There are other links that can tell you who this organization is and what they are trying to do.

I am not saying this particular group is the authority in the matter, I just found it by googling. I am grateful that American car manufacturers have finally begun to listen to the majority of consumers who want to use less gas and produce less pollutants. I honestly do not know what it will take other than a groundswelling demand that we pay attention to our global environment regarding this issue and demand our governments institute policies to address CO2 emissions and global warming. That the sun is going through a more active phase should only speed up our actions to clean up our planet.

The way world views change appear to hinge on a defining moment, but historians know that these are pivotal moments only and the groundswell for change had been occuring for some time. Dr. Masters is an important part of this process. And I applaud his efforts to bring to us regular folks the information we would not be exposed to otherwise. We are also noting the minute changes in the cycle, like the droughts and floods, extreme weather events, and nothing the records broken. What we are concerned about is the ecosystem not become broken, for example, the coral populations that contribute to the fish population...the knee joint is connected to the hip joint, etc.


And the fact that we are currently at all time lows for CO2 content of the atmosphere means ... what? nothing?

Thanks for the update, Doc. Closer to home, it's also been a very warm month. Here in northern Ohio, all of the official climate sites are on track for a top ten warmest May, including today's highs and lows. All of these sites easily set all-time record warm March temperatures. Below are the current monthly means (including today) with all-time ranking in parentheses. Threaded climate data exists back to 1871 at Cleveland and Toledo, 1873 at Erie, Penn., 1887 at Akron, 1897 at Youngstown, and 1916 at Mansfield.

Cleveland 65.0 (5th warmest)
Akron 66.6 (2nd warmest)
Toledo 64.9 (9th warmest)
Erie 63.2 (3rd warmest)
Mansfield 65.3 (3rd warmest)
Youngstown 64.4 (3rd warmest)

I'm plenty old.

You hear a lot of stuff that is conflicting. Don't we all?

But, what does the actual data tell you? Not someone's opinion about the number of temperature records broken, but the actual count? Doesn't it make sense to use actual data rather than hearsay?

If you think making your decisions based on data rather than opinion then take a look at what is happening to temperature records. We're blowing the old records away. It's not even close.

I don't know how old you are, but this is not the climate in which I grew up. When I was young the North Pole was surrounded by ice that was more than 20 feet thick and would never melt. Anyone who suggested that we'd ever see a melted Arctic Ocean would have been laughed out of town. Fact is, we could see the Arctic melt in the next couple of years. There's very little chance it will take ten years before we see a complete summer melt.
