It may not be as warm as it is in Europe here, 120 miles south of the arctic Circle, but it certainly counts as a heatwave around here- still 30 degrees at 9pm.

The stuck weather patterns across the NH has resulted in a solid week of humid air and afternoon and evening thunderstorms in Chicago. This is forecast to continue for the next 2 weeks. Farmers in the central U.S. do not need any more rain.

We have broken the weather. This will be the new normal.

Record-Smashing Heat Wave Bakes Alaska, Worsening Wildfires
https://amp.usatoday.com/amp/1616992001

On Saturday, downtown Juneau, Alaska's capital city, hit 83 degrees, breaking a record that had stood for 110 years. 

Saturday was only the fifth day since 1952 that Anchorage, Juneau and Fairbanks were all 81 degrees or warmer, according to Alaska-based climatologist Brian Brettschneider.

The temperature in Anchorage on Sunday soared to 82 degrees, the city's highest reading in three years, the weather service said.



... Sea surface temperatures last week there were as high as 9 degrees above the 1981-2010 average.

The northern Alaska warmth is weeks ahead of schedule and part of a “positive feedback loop” compounded by climate change. Rising ocean temperatures have led to less sea ice, which leads to warmer ocean temperatures, he said.

The last five years have produced the warmest sea-surface temperatures on record in the region, contributing to record low sea-ice levels.

Meanwhile, in southern Alaska, the next heat wave will be worse than the one over the weekend:

... “It’s forecast to be stronger and hotter than the one we just had,” Patrick Doll, a meteorologist with the weather service in Anchorage, told the Daily News. “Think of what we’ve been experiencing and tack on 2-4 degrees.”

Brettschneider tweeted that "we may approach all-time records in places."

The state's all-time record high temperature of 100 degrees

California Heatwave Cooks Mussels In Their Shells
https://www.treehugger.com/climate-change/california-heatwave-cooks-mussels-their-shells.html

... "On a 75 degree Fahrenheit day, the tissues inside a marine creature glued to a rock out of the water might rise to 105 degrees. The animals try to vent the heat building up inside of them but can’t without a breeze to carry it away. The mussels’ black shells trap even more heat. 'They were just literally cooking out there,' Helmuth said. 'Unfortunately this was the worst possible time.'"

What made this situation so unusual is that the heatwave occurred early in the summer season, when tides shift in the late morning and early afternoon. This exposes the mussels to more direct sunlight than they'd normally have later in the year, when tides shift in the early morning or late at night, reducing the danger for tide pool dwellers.

... it's indicative of the fragility of so many marine creatures, and how "a lot of ecosystems exist really close to the edge of what they can tolerate."

June Heatwave Unleashed a Pollution Bloom Over Europe
https://www.euronews.com/2019/07/02/watch-how-the-june-heatwave-unleashed-a-pollution-bloom-over-europe



June's unprecedented heatwave in Central Europe led to a spike in concentrations of ozone & pollutants in Central Europe. The Copernicus Atmosphere Monitoring Service created a visualisation of how ozone levels evolved through the week.

For, comparison a visualization of the ozone levels from June 11 to June 16, which was a week with "normal" temperatures for the season.

... Normal ozone levels are around 100 - 120 micrograms per cubic meter (µg/m³). Last week Europe has seen levels above 180 µg/m³, the information threshold according to WHO, above which "national authorities should inform the public and give advice immediately after an exceedance".

According to European agencies, the threshold reflects a 'level beyond which there is a risk to human health from brief exposure for particularly sensitive sections of the population'. When the threshold is exceeded, national authorities are required to inform the public, states the European Environment Agency.

The alert threshold, which poses a direct risk for the population, is 240 µg/m3. In order to maintain good health, however, there should not be more than 25 days per year where ozone levels exceed 120 µg/m3 (on an 8-hour average).

Climate change made Europe’s mega-heatwave five times more likely

Quote
After a series of unusually hot summers, France and other parts of Europe last week experienced another intense heatwave that broke temperature records across the continent.

For one group of climate scientists, the event presented a rare opportunity: to rapidly analyse whether the cause of the heatwave — which made headlines around the world — could be attributed to global warming. After a seven-day analysis, their results are in: climate change made the temperatures reached in France last week at least five times more likely to occur than in a world without global warming.

The scientists with the World Weather Attribution Project decided to take action when they saw the heatwave coming and ended up performing a real-time analysis while at a climate conference in Toulouse, France. As they met at the International Conference on Statistical Climatology, the city and most of France baked in searing temperatures — the southeastern town of Gallargues-le-Montueux broke national temperature records, hitting 45.9°C on 28 June.

...

To date, more than 200 attribution studies have examined whether climate change made particular events — including heat spells, droughts, floods and storms — more likely. Researchers found that about two-thirds of the extreme events they analysed were made more likely, or more severe, by the build-up of greenhouse-gases in the atmosphere.

I drew attention to the warmest June in Amazonia.



Indeed, in the Amazon last month there was a very large loss of the forest.

Brazil deforestation exceeds 88% in June under right-wing Bolsonaro
Jake Spring
4 MIN READ

BRASILIA (Reuters) - Deforestation in Brazil’s portion of the Amazon rainforest soared more than 88% in June compared with the same month a year ago, the second consecutive month of rising forest destruction under new right-wing President Jair Bolsonaro.

According to data from Brazil’s space agency, deforestation in the world’s largest tropical rainforest totaled 920 square km (355 square miles).

The data showing an 88.4% deforestation increase is preliminary but indicates the official annual figure, based on more detailed imaging and measured for the 12 months to the end of July, is well on track to surpass last year’s figure.

In the first 11 months, deforestation already has reached 4,565 square km (1,762 square miles), a 15 percent increase over the same period in the previous year. That is an area larger than the U.S. state of Rhode Island.

Environmentalists have warned that Bolsonaro’s strong remarks calling for the development of the Amazon and criticizing the country’s environmental enforcement agency Ibama for handing out too many fines would embolden loggers and ranchers seeking to profit from deforestation.

“Bolsonaro has aggravated the situation. ... He has made a strong rhetorical attack,” said Paulo Barreto, a researcher at Brazilian nongovernment organization Imazon.

The surge in deforestation comes as Brazil faces more pressure to protect its environment under the terms of the free trade deal between the European Union and South American blocs Mercosur agreed to last week.

The rainy season through April appeared to have held off a spike in deforestation that subsequently came with the dry season starting in May.

Deforestation rose 34% in May compared with the same month a year ago.

Bolsonaro’s office declined to comment, saying questions would be addressed by the Environment Ministry.

“We are adopting all measures to combat illegal deforestation,” Environment Minister Ricardo Salles told Reuters. “This week we had 17 enforcement teams simultaneously in all of the Amazon from Ibama.”

Brazil is home to 60% of the Amazon, which is the world’s largest tropical rainforest and is seen as vital to the global fight against climate change.

Grains trader Cargill, the largest privately held U.S. company, said last month that the food industry would not be able to meet a pledge to eliminate deforestation in their supply chains globally by 2020 and committed to do more to protect native environments in Brazil.

While the final text of the EU-Mercosur deal has not been released, an outline from the EU states the agreement includes a provision that the Paris Agreement on climate change must be effectively implemented along with other commitments to fight deforestation.

French President Emmanuel Macron had warned last week prior to agreement on the deal that he would not sign off on it if Brazil leaves the Paris accord.

Greenpeace forest strategist Paulo Adario said “all indications” are that deforestation will worsen under Bolsonaro, but he hopes news of a large increase will put pressure on the government to take action.

“When they have the final numbers, if it is really a lot, this will be a nightmare for Bolsonaro,” Adario said. “This is something that is really important from an international and Brazilian point of view because the Amazon is an icon.”

Third place since 2016:

1) 08.2016 1025 sq.km
2) 06.2016 951.5 sq.km
3) 06.2019 920.4 sq.km

Greater loss of rainforest in Amazonia was only during in the strongest El Nino.

The destruction of the forests of the planet means the destruction of the last chance to stabilize the concentration of greenhouse gases in the atmosphere.

 Verification of Heat Stress Thresholds for a Health-Based Heat-Wave Definition
https://journals.ametsoc.org/doi/full/10.1175/JAMC-D-18-0246.1

https://doi.org/10.1175/JAMC-D-18-0246.1.....open access...nice paper

Abstract
Heat waves represent a threat to human health and excess mortality is one of the associated negative effects. A health-based definition for heat waves is therefore relevant, especially for early warning purposes, and it is here investigated via the universal thermal climate index (UTCI). The UTCI is a bioclimate index elaborated via an advanced model of human thermoregulation that estimates the thermal stress induced by air temperature, wind speed, moisture, and radiation on the human physiology. Using France as a test bed, the UTCI was computed from meteorological reanalysis data to assess the thermal stress conditions associated with heat-attributable excess mortality in five cities. UTCI values at different climatological percentiles were defined and evaluated in their ability to identify periods of excess mortality (PEMs) over 24 years. Using verification metrics such as the probability of detection (POD), the false alarm ratio (FAR), and the frequency bias (FB), daily minimum and maximum heat stress levels equal to or above corresponding UTCI 95th percentiles (15° ± 2°C and 34.5° ± 1.5°C, respectively) for 3 consecutive days are demonstrated to correlate to PEMs with the highest sensitivity and specificity (0.69 ≤ POD ≤ 1, 0.19 ≤ FAR ≤ 0.46, 1 ≤ FB ≤ 1.48) than minimum, maximum, and mean heat stress level singularly and other bioclimatological percentiles. This finding confirms the detrimental effect of prolonged, unusually high heat stress at day- and nighttime and suggests the UTCI 95th percentile as a health-meaningful threshold for a potential heat-health watch warning system.

The summer of 2003 represented a turning point in the study of heat waves and their impacts on human health. The deaths of more than 70 000 people, caused by sustained, excess heat that dominated Europe in that period, urged most affected countries to implement heat-health action plans for the first time (Robine et al. 2008). Since 2003, warning systems based on meteorological forecasts have been put in place by governments across the continent to anticipate heat waves and reduce related excess mortality through the timely notification of prevention measures. Prevention measures are addressed both to the general population and to vulnerable groups, such as the elderly, who are particularly at risk of heat-related mortality, and to first responders, that is, national health services, as heat-wave events are associated with increases in emergency hospital admissions and ambulance call-outs (Kovats and Ebi 2006). Warning systems for health hazards in heat-wave conditions, known as heat-health watch warning systems (HHWWSs), use a variety of different indicators to identify and inform of a potentially hazardous heat-wave event (Lowe et al. 2011). The indicator mostly used in Europe is the 2-m air temperature. Parameters combining 2-m air temperature with relative air humidity, such as the apparent temperature or the heat index, are also adopted. The relationship between these indicators and mortality is well documented in literature (e.g., D’Ippoliti et al. 2010; Gasparrini et al. 2015).

I think this is the most appropriate page for extreme heat in an arctic river.
Emmonak is a Yupik community at the mouth of the Yukon river on the Bering sea.
The recent record heatwave in Alaska and the Yukon (referenced above in several posts) combined with extremely low water have pushed water temperatures well into record territory.
This is significant for the salmon upon which the river communities depend because as the fish migrate upstream, they generate body heat (despite being cold blooded) which has to be dissipated. The science is not complete yet, but the consensus is that a body temperature over 20C is too hot and the salmon stop migrating, find a cool spring and hang out until they have cooled off enough to move again.
The attached screenshot is from data supplied by the Alaska Department of Fish and Game.

Living on the Yukon Delta
The Yukon River drains a vast and diverse area of western Canada and Alaska. Where it approaches Alaska’s southwest coast on the Bering Sea, the great river spreads out and meanders across the Yukon Delta, a broad, flat region of wetlands and tundra underlain by permafrost. For thousands of years, Native Alaskans of Yup’ik and Cup’ik cultures have flourished in this unique region, sustained by hunting, fishing, and gathering the region’s diverse plant life.

Widespread, dangerous heat wave to expand across much of the U.S.
Quote
A stifling heat wave has begun to take shape across large portions of the United States, with millions likely to see temperatures creep toward the century mark, along with even higher heat indexes by this weekend.
The heat wave is already generating excessive heat watches in the central United States, and by Wednesday the national weather map is likely to feature a blanket of heat advisories from the National Weather Service. The combination of sultry dew points and scorching air temperatures approaching will help make this event a dangerous one from a public health perspective.
Cities including Chicago, St. Louis, Washington, Philadelphia, New York, Nashville and Kansas City, Mo., are likely to see at least three days with temperatures between 95 degrees and 100 degrees, along with dew points — a measure of the amount of moisture in the air — above 70 degrees.

Which is the best answer to Sep-2012 ASI lost (compared to 1979-2000)?
50% [NSIDC Extent] or
73% [PIOMAS Volume]

Volume is harder to measure than extent, but 3-dimensional space is real, 2D's hide ~50% thickness gone.
-> IPCC/NSIDC trends [based on extent] underestimate the real speed of ASI lost.

N.J. weather: It could feel like 110 degrees this weekend as scorching heat moves into region
https://www.nj.com/weather/2019/07/nj-weather-it-could-feel-like-110-degrees-this-weekend-as-scorching-heat-moves-into-region.html
https://www.cnn.com/2019/07/16/weather/weather-heatwave/index.html



“The worst day, right now, looks to be Saturday,” said Sarah Johnson, a meteorologist at the National Weather Service’s Mount Holly office. "Because of the humidity, we could see the heat index rise to between 105 and 110 degrees along the I-95 corridor."

The humidity, in part thanks to the remnants of Tropical Storm Barry, will also hike the heat index or apparent temperature — a measure of what the air feels like to the human body. It’s expected to feel like more than 100 degrees in most places Wednesday and Friday through Sunday across the state, peaking at near 110 on Saturday.

... The most grueling part of the approaching heat is that much of the state won’t get a break at night. High humidity (and New Jersey’s pervasive, heat-absorbing blacktop) will keep heat trapped overnight, and many places may not fall below 75 degrees until the beginning of next week, forecasts show.

The heat index, a measure of how the temperature feels to the human body when things like humidity are factored in, may not fall below 85 degrees in some places this weekend. In New York City, the temperature may not fall below 80 degrees at night between Friday and Monday.

According to the Weather Service forecast office in Chicago, “The heat is forecast to be oppressive and dangerous everywhere, with possibly some of the hottest conditions since 2012."

... Heat Index Temperatures in Washington, D.C., are forecast to peak near 113 F, which is close to the same level predicted for Death Valley, California. While actual temperatures will be higher in the deserts, humidity levels will make it feel as hot or hotter than the Southwest in parts of the Central and Eastern states.

Israel bakes as temperature climbs to near-record 49.9°C at biblical Sodom
Quote
Heat hits 40°C in Tel Aviv, even higher near Dead Sea; heat wave blamed for massive wave of brushfires

A heat wave that struck Israel Wednesday sent temperatures soaring to near-record breaking heights.

The highest temperature in the country was recorded on the southern shores of the Dead Sea, near the site of Biblical Sodom, where the mercury hit 49.9° Celsius (122° Fahrenheit), a record for the spot.

‘Quite Phenomenal’: Arctic Heatwave Hits Most Northerly Settlement in World
https://www.cbc.ca/news/canada/north/heat-wave-alert-nunavut-1.5212801
https://www.independent.co.uk/environment/arctic-heatwave-canada-climate-change-temperature-record-alert-nunavut-alaska-a9008181.html
https://www.theweathernetwork.com/ca/news/article/most-northern-tip-of-canadian-arctic-alert-nunvaut-reaches-21-degrees



Canada’s weather agency confirmed on Tuesday that temperatures in Alert, Nunavut, peaked at 21C at the weekend – far exceeding the July average for the area of around 7C.

Overnight temperatures on Sunday remained above 15C; again, well in excess of nighttime lows that usually hover around freezing in a settlement that lies less than 820 kilometres (508 mi) from the North Pole.

This is in fact, the first time a temperature warmer than 20° has been measured north of 80° on the planet. The previous record was held by Alert – the old benchmark being 20°C back in July 1956.

In a further alarm bell for the region, the mercury climbed above 20C for a second day on Monday – the first time Alert’s climate station has recorded two consecutive days of 20C-plus temperatures in its history.

Quote
... "Our models for the rest of the summer are saying, 'Get used to it."'

In Alert's case, the source of the Arctic beach weather is a large current of air that somehow found its way north from the U.S. southeast, Phillips said.

It could be related to changes in the jet stream, a fast-moving, high-altitude river of air that moves west to east. That current has slowed in recent years and has become more unstable, sometimes looping much farther north or south than normal.

And now imagines what kind of temperatures we would see once there will be close to zero ice left in summer.

Next we can assume that those temperatures would occur more widely spread around above the arctic circle.

Next we translate the results of such considerations into water temperatures and the related
effects to the freezing season as well as local and hemisphere weather.

And now what would be the take of those who "deny" a game change after a BOE that would occur in August or earlier.

I know there is a thread for this but > 20C in Alert over several days and not that far below over weeks are significant events, kind of warning foreboding events IMO.

The ultimate event and one that can neither be prevented nor worked around nor resolved will be a relatively fast SLR, IMO that will accelerate and be quicker than most current predictions imply.

But only for the ignorant themselves. For the vast majority it usually end in an eternal sequence of disasters with varying gaps between major events and for the approximate 2% of those who fully understand and draw the big pictures it is, in additions, a painful annoyance.

But not a record breaker..... (But in a few years might last a long, long time)

From Forbes.com  from the US National Weather Service...

Topline: An excessive and potentially dangerous heatwave is expected to grip much of the Midwest and East Coast on Thursday and through much of the weekend, with temperatures and humidity expected to reach record-highs and well into the triple digits.

The National Weather Service has issued an Excessive Heat Warning—the most serious heat-related alert—for several areas on Thursday. And even more are under a less serious Heat Advisory.

Excessive Heat Warnings are given when the heat index (the combined temperature and humidity, or the “feels like” temperature) is forecasted to reach 105 degrees Fahrenheit or higher. Additionally, low temperatures during the night are expected to reach record highs.
Heat killed more people last year than any other type of extreme weather, according to the NWS.

Kansas City: Kansas City, along with northwestern Missouri and northeastern Kansas, is currently under an Excessive Heat Warning, which will continue until 8 p.m. Saturday.

New York City: An Excessive Heat Warning will be in effect from noon on Friday to 8 p.m. Sunday.

Oklahoma City: An Excessive Heat Warning is currently in effect until 8 p.m. Wednesday. A Heat Advisory will be in effect from 11 a.m. to 8 p.m. Friday.

Chicago: The city of Chicago and all of DuPage, Cook and Kane Counties will be under an  Excessive Heat Warning from 10 a.m. Friday to 7 p.m. Saturday.

Louisville: Louisville and parts of central Kentucky are currently under an Excessive Heat Warning until 7 p.m. Sunday.

Detroit: Detroit is currently under an Excessive Heat Warning and will remain so until 8 p.m. Saturday.

Boston: The city of Boston and the entire state of Massachusetts will be under an Excessive Heat Warning from noon Friday to 8 p.m. Sunday.

Washington, D.C.: The Washington, D.C. region will be under a Heat Advisory from 11 a.m. to 9 p.m. Friday. The alert will be pushed up to an Excessive Heat Watch from Saturday morning to Sunday evening.

Central Pennsylvania: The region will be under an Excessive Heat Warning starting noon Thursday to 8 p.m. Saturday.

Philadelphia: Philadelphia is currently under an Excessive Heat Warning and will be until 10 p.m. Sunday.

Atlantic City: An Excessive Heat Warning has been issued for western, central and southern parts of New Jersey from noon Friday to 10 p.m. Sunday.

Delaware: The entire state of Delaware and nearby Ocean City, Maryland, will be under an Excessive Heat Warning from noon Friday to 10 p.m. Sunday.

Cedar Rapids, Iowa: All of eastern Iowa is under an Excessive Heat Warning until 7 p.m. Saturday.

Lincoln, Nebraska: Eastern and southern Nebraska are under an Excessive Heat Warning until 7 p.m. Saturday.

State of Emergency Declared in Wisconsin After Electrical Fires
https://www.cbsnews.com/amp/news/madison-wisconsin-substation-fires-governor-tony-evers-declares-state-of-emergency-today-2019-07-19/

Wisconsin Governor Tony Evers declared a state of emergency and called in the National Guard on Friday after two fires and explosions at electric substations. The city's utility, Madison Gas & Electric, said the fires had been contained but there were still some customers without power Friday night.

... An executive order issued by Evers said the declaration was issued to "provide support during the large power outage that is exacerbated by the extreme heat wave affecting the area," CBS Madison affiliate WISC reported. The heat index value for Madison means temperatures felt like 103 degrees on Friday.

Right now it's it 95F with a heat index of 105F(40,5C) and climbing, uncomfortable it is.  63yrs hu .. A lite hearted philosophical remark if I may: Life is like roll of toilet paper, the closer to the end you get the faster it goes!  ;)

It hasn't even begun.

I've got another 36 hrs of heat index north of 100 F.  I am not amused.

Appreciate the kind thought, though.  :)

Currently: 98 F - FEELS LIKE 121° - 61% Humidity according to Wunderground.com

https://www.wunderground.com/weather/us/ct/myrtle-beach/KCTMYRTL2

@ 1:30 local time 102°F - FEELS LIKE 144°  :P

Thanks Nanning. No, peaking here (US mid-atlantic) this weekend.  Temps around 38 (100 F) and heat index around 43.

These were the 5pm EDT Saturday heat index readings across the lower 48. Some relief is on the way Sunday for much of the Central States but the East will see another day of excessive heat.

https://mobile.twitter.com/NWS/status/1152708819291688960

https://www.cbsnews.com/amp/live-news/heat-wave-2019-extreme-heat-advisory-warning-deaths-latest-weather-forecast-us-nyc-2019-07-20/

At least six deaths were blamed on the excessive heat: 4 people died in Maryland, while one died in Arizona and another died in Arkansas.

Baltimore logged a heat index of 122 degrees early Saturday evening. The city is one of a handful of locations experiencing a heat index in the triple digits, including cities in the Midwest and East Coast.

... After heat indexes in parts of Minnesota made temperatures feel as hot as 116 degrees, the area is under a severe thunderstorm and flash flood warning on Saturday.

A compact cluster of thunderstorms are tracking due east across central Minnesota from late Saturday morning through the afternoon, CBS Minnesota reported. This line of storms could pack near-hurricane-force winds.

... The National Weather Service has issued an "excessive heat warning" for most of southern New England on Saturday, expecting heat indexes near 110.

Central Maine, meanwhile, experienced blackouts Saturday.

... Police in Braintree, Massachusetts, are asking residents "to hold off" all criminal activity until the extreme heat is over.

"Folks. Due to the extreme heat, we are asking anyone thinking of doing criminal activity to hold off until Monday," the department wrote in a Facebook post. "It is straight up hot as soccer balls out there. Conducting criminal activity, in this extreme heat is next level henchmen status, and also very dangerous."

"Stay home, blast the AC, binge 'Stranger Things' Season 3, play with the face app, practice karate in your basement We will all meet again on Monday when it's cooler.

This is the most extreme forecast for Paris or any major European capital I think I can ever recall.

The all-time high in Paris was 104.7F / 40.4C set on July 28th, 1947.

Looks like a lot of monthly and all time records could fall across western Europe in the coming week.
In the UK, many models are predicting temperatures of about 37C in the south east on Wednesday and Thursday, with a few models creeping close to 40C.
This is quite extraordinary, considering the July record is 36.7C from 2015 and the all time record is 38.5C from August 2003.

I reckon it will be the Benelux countries that will set new all time records this week.

re 244. Paris

That makes no sense in C and is not that impressive in F (19,4 C).

It is now 31 C or 87 F in Paris.
