"Record-Breaking Heat to Ease " www.weather.com/news/weather-forecast/extreme-heat-southwest-120-degrees-20130626"At Death Valley National Park, the official high of 129 degrees at Furnace Creek Sunday established a new June record for that notoriously toasty site. "One could almost think we're not cooling at all. One of the greatest heat waves in North American history peaked on Sunday and Monday, but will still bring some of the hottest temperatures ever recorded to portions of the Western U.S. during the afternoon today. The extraordinary heat wave, caused by an unusually extreme standing wave pattern in the jet stream, brought Earth's highest June temperature ever recorded on Sunday, June 30, when the mercury hit 129.2°F (54.0°C) in Death Valley, California. (my bolding) wunderground.com/blog/JeffMasters/comment.html?entrynum=2451Sounds like a repeat of the Great Russian Heatwave of 2010 to me. Yep. But this is a very short one. Would not show up in proxy data.

Ice volume in the thirties and fourties? Not much of a clue but certainly not as high as the seventies.

So you're saying nothing to see here, move on? Somehow I think the only thing you ever manage to say is just that.

No clue to how low extent/volume was during the last Arctic heatwave. I know that it was decades before the NW Passage was open again. In fact the path taken by the St Rock has still not been open. This would indicate that current ice is not that different from past ice dynamics as the Arctic is very fluid.

Sigurdur, you are all they way in your nonsense mode again. I can see you are somewhat upset by the new record.

It is a great pity that the thermometer was only invented towards the end of the little ice age.

In case you were wondering if the scout had been to death valley, of course it has. Thanksgiving time as it is always very hot in summer. But I have been visiting Death Valley since around 1960. Usually in winter as the climate there is unique. "Why so Hot? The depth and shape of Death Valley influence its summer temperatures. The valley is a long, narrow basin 282 feet (86 m) below sea level, yet is walled by high, steep mountain ranges. The clear, dry air and sparse plant cover allow sunlight to heat the desert surface. Heat radiates back from the rocks and soil, then becomes trapped in the valley's depths. Summer nights provide little relief as overnight lows may only dip into the 85°F to 95°F (30°C to 35°C) range. Heated air rises, yet is trapped by the high valley walls, is cooled and recycled back down to the valley floor. These pockets of descending air are only slightly cooler than the surrounding hot air. As they descend, they are compressed and heated even more by the low elevation air pressure. These moving masses of super heated air blow through the valley creating extreme high temperatures. How extreme is Death Valley's climate? Record Temperatures The hottest air temperature ever recorded in Death Valley (Furnace Creek) was 134°F (57°C) on July 10, 1913. During the heat wave that peaked with that record, five consecutive days reached 129° F (54°C) or above. Death Valley holds the record for the hottest place on earth. Oddly enough, 1913 was also the year that saw Death Valley's coldest temperature. On January 8 the temperature dropped to 15°F (-10°C) at Furnace Creek. Longest summers The greatest number of consecutive days with a maximum temperature of 100° F or above was 154 days in the summer of 2001. The summer of 1996 had 40 days over 120° F, and 105 days over 110° F. The summer of 1917 had 43 consecutive days with a high temperature of 120° F or above. Highest ground temperatures The highest ground temperature recorded was 201° F at Furnace Creek on July 15, 1972. The maximum air temperature for that day was 128° F. Dry as a bone No rain was recorded in the years of 1929 and 1953. The driest stretch on record was only 0.64 inches (1.6cm) of rain over a 40-month period in 1931 to 1934. Weather data was compiled from park and National Weather Service record summaries for the years 1911 through 2007 for Furnace Creek in Death Valley, California." link

Not a place I would like to be. I have been there when it was 124 degrees. Heck in July the "average" high is 116 degrees. The record for Death Valley and the world is 134 degrees set on July 10, 1913 a century ago. Considering the sun is lower on the date of the all time world record than June 29 this temperature is not an unusual record.

Mr. Número and Mr wolf,
Let's assume you both are correct that unprecedented warming is occurring in the arctic. I am curious. Is this a problem? If so, why are you both so gleeful about the verification of your predictions? Are you misanthropes? If not, why the interest in arctic ice? Just a passing fancy, or do you want to see humanity reduce its numbers after suffering through the failure of the electrical grid? Is it wiser to preserve the arctic ice as billions die? What is your agenda?
