Wildfires in Canada cause poor air quality across North America and Europe

by Featured NewsSustainabilityWildland Fire

Wildfires continue to burn across Canada in August

As reported by Copernicus, wildfires continue to burn across the boreal regions of North America, particularly in Western Canada.

Provinces including the Northwest Territories, British Columbia, Alberta, Saskatchewan, and Manitoba are experiencing intense wildfire activity.

As of August 2024, Canada’s total wildfire carbon emissions have reached over 80 megatonnes, nearing the levels seen in 2023, the country’s highest August emissions since 2003.

In Saskatchewan and Manitoba, emissions for August are the highest on record in the CAMS database.

The Northwest Territories have also seen sharp increases in emissions following heatwave conditions.

British Columbia and Alberta have recorded their highest annual emissions, trailing only behind 2023.

Wildfires impact air quality across North America and Europe

The wildfires have had wide-reaching effects on air quality, not only in Canada but across North America and Europe.

Since early August, smoke has travelled from Western Canada to the east coast of the United States, reducing air quality in major cities.

By mid-August, smoke had crossed the North Atlantic Ocean, reaching Western Europe.

According to CAMS, on 17 August, areas such as Ireland, the United Kingdom, and France reported high aerosol optical depth (AOD) values, indicating significant smoke particle concentrations in the atmosphere.

AOD levels reflect the density of particulate matter in the air, and elevated levels are linked to reduced air quality and hazy skies.

CAMS analysis showed these impacts spreading further across Europe.

Aerosol depth measurements show global spread

CAMS confirmed the spread of smoke particles across Europe by evaluating aerosol optical depth measurements.

Independent Aeronet data confirmed these findings at monitoring stations in Cork (Ireland), Camborne (United Kingdom), and Brest and Arcachon (France).

The measurements revealed that the smoke particles from Canadian wildfires reached European airspace, supporting forecasts of poor air quality across affected regions.

These findings indicate that the fires in Canada are not only a domestic issue but a global one, affecting air quality across vast distances.

CAMS continues monitoring fire emissions and impacts

The Copernicus Atmosphere Monitoring Service continues to track the wildfires, their emissions, and their atmospheric impact through satellite data and forecasts.

CAMS regularly updates the total estimated carbon emissions from the fires and provides insights into the transport of smoke across the globe.

The ongoing data collection helps governments and environmental agencies to better understand the evolving situation and respond accordingly.

CAMS continues to collaborate with independent monitoring stations to validate its findings and ensure the accuracy of its forecasts.

Canadian wildfires affecting air quality across continents: summary

The intense wildfires across Western Canada are causing major atmospheric impacts both locally and internationally.

According to Copernicus, smoke has travelled from Canada across the North Atlantic, reaching parts of Europe and affecting air quality.

Canadian provinces, including Saskatchewan, Manitoba, and the Northwest Territories, have seen record-breaking wildfire carbon emissions in August 2024.

Meanwhile, the Copernicus Atmosphere Monitoring Service has confirmed significant smoke transport across North America and Europe, with evaluations showing agreement between forecasts and independent monitoring stations in Ireland, the United Kingdom, and France.

These fires continue to contribute to global air quality concerns.

Global wildfire report shows climate change is increasing extreme fire seasons

by Breaking NewsWildland Fire

Global wildfire patterns shift due to climate change

A recent report published by Matthew W. Jones et al. via Earth System Science Data shows that global wildfires are increasingly driven by climate change.

From March 2023 to February 2024, 3.9 million square kilometres burned globally.

This is slightly below the average from previous seasons, but fire carbon emissions rose by 16% compared to earlier years.

Notable events include record-breaking fires in Canada and Greece, deadly wildfires in Hawaii and Chile, and drought-driven fires in Amazonia and northern South America.

The report revealed that anthropogenic climate change has increased the likelihood of extreme fire seasons.

In Canada, fire emissions reached nine times the average, driven by a combination of high fire weather and dry fuels.

Similar patterns were observed in Greece and Amazonia, where fires were exacerbated by long-term droughts and climate change.

North America hit by record-breaking fire season

In North America, the fire season was marked by extreme conditions, particularly in Canada, where over 150,000 square kilometres burned.

Emissions from Canadian boreal forests were nine times higher than average, and more than 232,000 people were evacuated due to the fires.

The fires also caused a significant degradation in air quality, with residents in the United States and Canada exposed to unsafe levels of particulate matter for extended periods.

Meanwhile, in the United States, wildfires were less widespread but still deadly.

The Lahaina fire in Maui, Hawaii, claimed 100 lives and displaced 10,000 people.

Texas experienced its largest-ever wildfire, which destroyed over 130 homes.

South America faces widespread fires amidst drought conditions

South America experienced widespread wildfires, particularly in the northwest, driven by drought and high fire weather.

In Brazil’s Amazonas state, record fire counts were observed, severely affecting air quality in cities like Manaus.

Neighbouring countries, including Bolivia, Venezuela, and Peru, also saw higher-than-average fire counts.

In Chile, deadly fires in Valparaíso led to the deaths of 131 people and widespread damage.

These fires were driven by persistent dry conditions, which created ideal conditions for large and fast-spreading wildfires.

Future risks and climate change projections

The report warns that if global climate policies do not reduce emissions, future wildfire seasons could see even more extreme events.

In Canada, fire events similar to those in 2023 are predicted to occur six to 10 times more frequently by the end of the century under a high-emission scenario.

The likelihood of extreme fires in the Amazon is expected to increase by up to 50% by 2090, with similar risks in Greece and other parts of Europe.

The report highlights that significant climate change mitigation efforts are required to reduce these risks and prevent the escalation of wildfires globally.

Global wildfire report shows climate change is increasing extreme fire seasons: Summary

The 2023–2024 State of Wildfires report reveals that climate change is causing more frequent and intense wildfires worldwide.

During this period, 3.9 million square kilometres burned globally, with carbon emissions 16% higher than the average.

The most extreme fires occurred in Canada, Greece, Hawaii, and the Amazon.

Anthropogenic climate change has been linked to a significant increase in the probability of these events.

The report warns of future risks if global emissions are not reduced, projecting more frequent extreme fire seasons in the future.

Effective climate mitigation efforts are seen as critical to reducing these risks.

Faulty power cable may have caused devastating Greek wildfire

by Featured NewsWildland Fire

Investigation underway into deadly wildfire near Athens

Investigators are looking into the possibility that a faulty power cable may have caused Greece’s worst wildfire this year, as reported by Reuters.

The blaze killed one woman and burned 10,000 hectares of land near Athens, an area roughly the size of Paris.

The fire broke out on August 11 from a forested area near the town of Varnavas, located 35 kilometres from Athens.

Within a day, it had spread to the northern suburbs of the capital.

Residents and officials have been questioned, including a 76-year-old man who pointed to a loose cable attached to a wooden electricity pole near his home as a possible cause of the fire.

Wildfire spreads rapidly across 40 kilometres

The fire quickly covered a distance of 40 kilometres, reaching Athens’ suburbs of Penteli and Vrilissia.

Milder winds have since slowed the fire, but authorities warned of potential flare-ups as winds were expected to intensify.

The fire broke out during a period of high temperatures and strong winds, factors that had placed the country on high fire alert.

Greece has experienced more than 8,000 wildfires in 2023, with climate change contributing to hotter temperatures and drier conditions, increasing the likelihood of fire outbreaks.

Investigators focus on faulty electrical infrastructure

Authorities are focusing their investigation on the electrical infrastructure near the fire’s origin.

Engineers have been deployed to examine the cause, while the power network operator HEDNO stated: “We have no indication that anything wrong such as a short-circuit happened.”

However, the investigation is still ongoing, and arson has not been ruled out as a possible cause.

Local media reported that some residents heard explosions before the fire broke out, and there were accounts of two separate fires occurring initially.

However, official investigations remain focused on the faulty power cable scenario as the leading cause.

Impact of climate change on wildfire risk

Greece has faced increasing wildfire risks in recent years due to the impact of climate change.

This year, the country recorded its warmest winter on record and is on track for its hottest summer, with minimal rainfall in many regions.

These conditions create a perfect environment for wildfires, and the fire brigade noted that the risk of fire outbreaks continues to rise.

In addition to weather conditions, many wildfires in Greece have been attributed to voluntary or involuntary arson, as well as short circuits in electrical infrastructure.

The current investigation will determine whether human factors or climate-related conditions played a greater role in this devastating fire.

Faulty power cable may have caused devastating Greek wildfire: Summary

A faulty power cable is being investigated as a potential cause of Greece’s worst wildfire this year, which killed one woman and burned 10,000 hectares near Athens.

The fire started on August 11 in Varnavas and quickly spread to the capital’s northern suburbs.

Investigators are focusing on the possibility that a loose cable on a wooden electricity pole may have triggered the fire.

Greece’s power network operator, HEDNO, has denied any evidence of malfunction, while local media reported explosions and multiple fire outbreaks.

The investigation continues amid warnings of the growing wildfire risk due to climate change.

Greek firefighting efforts continue to battle Athens wildfire aftermath

Wildfire near Athens devastates 25,000 acres

Greek firefighting forces continue their efforts to fully extinguish the remnants of a wildfire that erupted on August 11 in the northeastern outskirts of Athens.

The fire claimed one life, destroyed numerous homes and businesses, and scorched over 25,000 acres of land.

Although the fire has been largely contained, authorities remain on alert for potential flare-ups due to extreme weather conditions.

The wildfire originated near Varnavas, approximately 22 miles northeast of Athens, and rapidly spread due to strong winds and extreme heat.

Thousands of residents were evacuated as the fire impacted over 104 square kilometers of land.

Initial assessments by local authorities reported that at least 78 homes were uninhabitable, while 22 businesses suffered damage.

The fire’s swift spread has been linked to the phenomenon of spotting, where embers are carried by the wind to ignite new fires.

Nikos Lavranos, head of the Greek Federation of Fire Service Employees, said: “That is more evident in recent years. Conditions have changed, and it’s becoming more usual.”

Government response and firefighting measures

Greek Prime Minister Kyriakos Mitsotakis visited Elefsina’s military airport to personally thank firefighting aircraft pilots for their efforts.

He acknowledged the climate crisis’ role in the severity of the fire and called for improvements to Greece’s disaster response.

“This is an effort we all make in response to a significant climate crisis,” Mitsotakis said during his visit.

International support has played a key role in the firefighting efforts.

Greece received aid from nine countries, including Turkey, which provided ground crews and aerial assistance through water-dropping planes and helicopters.

These efforts helped to contain the fire just outside of Athens, but firefighting crews remain on high alert due to ongoing weather threats.

Impact on the environment and infrastructure

The wildfire’s destruction extends beyond homes and businesses.

According to Greece’s National Observatory, this fire represents yet another setback for Greece’s natural environment.

The Attica region has lost 450 square kilometers of forest over the past eight years due to wildfires, with the recent blaze accounting for 37% of the region’s forested land.

Satellite imagery from the European Union’s Copernicus Emergency Management Service revealed the full extent of the fire’s damage, while NOAA satellites tracked a smoke cloud stretching 180 miles southwest toward Libya.

Greece’s government has implemented various compensation and relief measures to assist those affected by the disaster.

Ongoing inspections aim to determine the full scope of the damage.

Firefighting crews continue to monitor the fire-stricken area to prevent further incidents as the country remains on high alert for potential wildfires.

International collaboration and ongoing monitoring

The wildfire near Athens has drawn international attention, leading to cooperation between Greece and its neighbouring countries.

Assistance from Turkey and other nations played a crucial role in the firefighting operations, particularly in preventing the fire from reaching Athens.

The European Union and other organisations also provided satellite data to assist in assessing the fire’s impact and guiding firefighting efforts.

Despite the fire being largely contained, the potential for flare-ups remains a concern.

Firefighting teams continue their monitoring efforts around the clock.

The risk of further incidents is heightened by the region’s extreme heat and gusty winds, with authorities focusing on ensuring the safety of both residents and firefighters.

This situation highlights the growing challenges Greece faces due to climate change and its impact on the country’s vulnerability to wildfires.

Greek firefighting forces work to contain wildfire near Athens: Summary

Greek firefighting forces remain engaged in extinguishing a wildfire that broke out on August 11 near Athens, which claimed one life, destroyed homes and businesses, and burned over 25,000 acres of land.

European Commission activates Civil Protection Mechanism to aid Greece and Albania amidst wildfires

by Aerial FirefightingFeatured NewsWildland Fire

European response to Greece wildfires

The European Union has mobilised emergency support for Greece and Albania in response to severe wildfires, as reported by the Directorate-General for European Civil Protection and Humanitarian Aid Operations (ECHO).

The EU Civil Protection Mechanism has been activated to facilitate this response, with the European Commission’s Emergency Response Coordination Centre (ERCC) coordinating firefighting efforts from various member states.

To assist Greece, the ERCC has dispatched both aerial and ground resources, including two rescEU firefighting planes from Italy, a rescEU helicopter from France, and a helicopter provided by Serbia.

Ground teams from Czechia, France, Italy, Serbia, and Romania have also been deployed.

Additionally, firefighters from Romania, Malta, and Moldova, who were already stationed in Greece, have joined the efforts to combat the flames.

Assistance to Albania amid the crisis

In Albania, the EU’s response includes the deployment of a multipurpose military plane from Romania, which has a capacity of 6 tons of water.

This aircraft is set to arrive on 14 August to aid in firefighting efforts.

The Commission continues to monitor the situation closely and is prepared to provide additional assistance if necessary.

The mobilisation of resources is part of the EU’s broader preparedness for the current wildfire season.

The EU has bolstered its rescEU and European Civil Protection Pool, which now consists of 28 planes and 4 helicopters stationed across 10 Member States.

More than 540 firefighters from 12 countries are prepositioned in key locations across Europe, ready to support local efforts.

France, Italy, and Czechia contribute additional resources

France, Italy, and the Czech Republic have each committed further resources to support Greece’s firefighting operations.

France is sending a Super Puma helicopter equipped with a water bucket, alongside 180 civil security firefighters and 55 lorries.

Italy is contributing two Canadair firefighting aircraft, and the Czech Republic is dispatching 75 firefighters with 25 vehicles, including nine waterborne units.

Additional assistance from Spain and Turkey is anticipated in the coming days.

Greece has deployed around 670 firefighters to combat the fires, which the national fire department spokesman, Vassileios Vathrakogiannis, described as “exceptionally dangerous.”

Local residents face fire threat

Residents in the affected areas of Greece have faced the immediate threat of encroaching wildfires.

Spyros Gorilas, a resident of Dioni, described the harrowing conditions: “The wind would go in one direction and then in the other. The smoke was suffocating. You couldn’t see. Your eyes teared up. You couldn’t breathe.”

Another resident, Giannis Alvanos, who had recently rebuilt his home after losing it to a fire two years ago, evacuated when ordered but returned to protect his property.

“I didn’t want to lose my property for a second time,” Alvanos said, while commending the firefighters for their rapid response.

Wildfires are a common occurrence in Greece during the hot and dry summer months, but experts warn that climate change is exacerbating the frequency and intensity of these fires.

Last year, wildfires in Greece resulted in over 20 deaths.

Wildfire forces evacuations across multiple regions near Athens

As reported by AP News, a significant wildfire has erupted on the northern outskirts of Athens, Greece, leading to widespread evacuations.

The blaze, which began on Sunday afternoon approximately 35 kilometers from the capital, has been fueled by strong winds and tinder-dry conditions after a prolonged period of heatwaves.

By Monday morning, hundreds of firefighters, supported by over two dozen water-dropping planes, were engaged in combating the fire.

Evacuation orders were issued for more than a dozen areas, including Marathon and several suburbs of Athens, with local authorities providing shelters and hotel accommodations for those displaced.

Authorities have warned that the situation remains precarious, with the fire department urging residents to comply with evacuation orders to avoid putting themselves and rescue teams at risk.

The fire department’s spokesperson, Col. Vassileios Vathrakogiannis, highlighted the ongoing threat posed by strong winds: “During the night, the wind remained strong, creating dangerous situations.”

High alert across Greece as weather conditions fuel fire risks

Greece remains on high alert for wildfires as meteorologists and government officials warn of heightened danger across half the country.

The fire in northern Athens is the latest in a series of blazes that have plagued the nation during a particularly dry summer.

According to the Climate Crisis and Civil Protection Minister, Vassilis Kikilias, a “red alert” has been issued, with the potential for further wildfires expected to persist until Thursday.

The situation has been exacerbated by the country’s severe weather conditions, with repeated heatwaves following an unusually dry winter, leaving the landscape extremely vulnerable to fires.

Authorities have deployed significant resources, including more than 500 firefighters and 152 vehicles, to manage the blaze, which at times has seen flames reach heights of over 25 meters.

Health impacts and safety measures as fire spreads

The ongoing fire has also raised health concerns for residents of Athens and surrounding areas.

A children’s hospital and a military hospital were evacuated early Monday as the fire department responded to the escalating threat.

Additionally, local media reported that two firefighters sustained minor injuries, while several civilians required treatment for smoke inhalation.

Authorities have established evacuation centres, including sports halls and hotel rooms, to accommodate those forced to flee their homes.

Despite these efforts, there have been instances where residents ignored evacuation orders, later requiring rescue and putting additional strain on firefighting operations.

Historical context and ongoing challenges in managing wildfires in Greece

Wildfires are a recurrent issue in Greece, particularly during the hot, dry summer months.

However, the frequency and intensity of these fires have been increasing, a trend that authorities attribute to climate change.

The current fire near Athens has drawn comparisons to past tragedies, including the 2018 fire in Mati, which claimed over 100 lives.

In 2023, wildfires in Greece resulted in the deaths of more than 20 people, including 18 migrants who were trapped by flames in a forest in northeastern Greece.

Wildfires in North America generate thunderstorms as climate change worsens

by Featured NewsWildland Fire

Wildfires in California and Canada generate pyrocumulonimbus clouds

The recent fires in northern California and the resort town of Jasper in Canada have not only burnt vast areas but also produced their own thunderstorms.

As reported by Brian Owens for nature.com, these fires have created ‘pyrocumulonimbus’ clouds, which can trigger lightning and spark additional fires.

Before 2023, the occurrence of such clouds was relatively rare.

However, in recent years, there has been a significant increase in their formation, with Canada alone reporting 140 occurrences in the previous year.

According to Mike Flannigan, a wildfire expert at Thompson Rivers University, this trend is likely to continue unless measures are taken to address climate change.

Rapid spread of fires surprises officials

The Park Fire in northern California and the Jasper Fire in Canada both exhibited faster-than-expected spread.

In California, the Park Fire expanded from a small blaze to more than 140,000 hectares within three days, becoming the fourth-largest fire in the state’s history.

Similarly, the Jasper Fire in Canada reached the town in just two days, half the time predicted by models.

Daniel Swain, a climate scientist at the University of California, Los Angeles, noted: “We’ve seen a lot of fires behave like these ones in recent years, which I don’t think is reassuring at all.”

Climate change and its role in wildfire intensity

Climate change has made conditions more conducive to wildfires, particularly by creating drier fuels.

Extended heatwaves left the forests in both California and Canada tinder-dry, setting the stage for more intense and fast-moving fires.

According to James Gomez, a PhD student studying wildfires at the University of California, Riverside, warmer air, which holds more moisture, draws more water from vegetation, leaving it drier and more flammable.

This results in faster-moving fires with greater thermal output.

Fire management practices and unintended consequences

Fire suppression practices over the past century have contributed to a “fire deficit” across much of the western United States, leading to denser forests that are more susceptible to large fires.

Daniel Swain pointed out that current forest conditions are far from their natural state due to these policies.

In contrast, Canadian forests are naturally denser, and the population density is lower, reducing the impact of these management practices.

Anthony Taylor, a forest-management specialist at the University of New Brunswick, emphasized the importance of addressing climate change to prevent extreme fires in the future.

Wildfires in North America generate thunderstorms as climate change worsens: Summary

Recent wildfires in northern California and Jasper, Canada, have produced pyrocumulonimbus clouds, leading to lightning that sparked additional fires.

These events have become more common, reflecting a trend linked to climate change.

Both fires spread faster than expected, with the Park Fire in California growing from 1–2 hectares to over 140,000 hectares in just three days.

Climate change has increased the likelihood of such intense fires by creating drier fuels and more extreme fire behaviour.

Fire management practices have also contributed to the severity of wildfires, particularly in the United States.

Garden design can reduce wildfire risk and promote sustainable co-existence with wildfire says recent study

by ResearchWildland Fire

Global review highlights wildfire risk management strategies

A recent study published in Natural Hazard reviewed guidelines on creating defensible space to reduce wildfire risk around homes in wildland and rural urban interfaces.

The research, conducted by Ondei, Price, and Bowman, emphasized that defensible space helps reduce house loss and provides a safe area for residents and firefighters to defend properties during wildfires.

Guidelines from various regions, including Africa, Europe, North America, South America, and Oceania, were examined.

The study proposed a conceptual model to mitigate fire attack mechanisms through recommended approaches such as fuel type management, reduction of fuel amount, and spatial distribution.

Key recommendations include reducing or removing all fuels, especially dead plant material, within 1.5 meters of a house, minimizing fuel connectivity within 10 meters, and managing on-ground fuel in the outer part of the garden (10-30 meters).

Scientific support for defensible space design elements

Evidence from scientific literature broadly supports the defensible space design elements recommended in the guidelines.

Post-fire assessments revealed that garden characteristics significantly affect house survival during wildfires.

Effective defensible spaces are categorized into three zones: Fuel-free zone (within 1.5 meters), Open zone (1.5-10 meters), and Tree zone (10-30 meters).

These zones focus on minimizing horizontal and vertical fuel connectivity and managing vegetation to provide canopy shielding from ember attack and radiant energy.

Further empirical and modeling research is needed to identify optimal zonation around houses and understand how garden structure, species composition, and moisture status affect the risk of ignition from embers, radiant heat, and flames.

Implementation challenges and recommendations

While guidelines are available, their implementation presents challenges.

Recommendations include thinning vegetation, removing dead plant material, and selecting low-flammability species.

However, the variability in guidelines across regions suggests a need for more standardized, evidence-based recommendations.

Additionally, the use of non-flammable materials for ground cover and fencing is emphasized to reduce garden flammability.

The study also highlighted the importance of irrigation and the potential use of sprinklers in defensible spaces, although their effectiveness depends on proper installation and maintenance.

Ensuring compliance with these guidelines, particularly in high-risk areas, requires community engagement and possibly legal enforcement to achieve better wildfire risk management.

Future research directions

The study calls for more research on the effectiveness of specific defensible space zones and their characteristics.

There is also a need to explore the impact of garden biodiversity on fire risk and the potential benefits of wildlife-friendly gardens.

Understanding the social acceptability and economic feasibility of maintaining defensible spaces is crucial for encouraging community adoption of these practices.

Ongoing interdisciplinary research into defensible space is essential for developing more fire-adapted communities and promoting sustainable coexistence with wildfires.

Reducing wildfire risk through garden design: Summary

A study published in Natural Hazard reviewed international guidelines on creating defensible space to reduce wildfire risk.

Key recommendations include managing fuel types, amounts, and spatial distribution around homes.

Evidence supports these design elements, though further research is needed to optimize zonation and understand the impact of garden structures.

Implementation challenges highlight the need for standardized guidelines and community engagement.

Future research should focus on specific zone effectiveness, garden biodiversity, and social acceptance to develop fire-adapted communities.

California wildfire ranks as state’s fourth largest on record

by Featured NewsWildland Fire

Firefighters battle massive blaze in California’s Central Valley

More than 6,000 firefighters are combating the largest wildfire in the U.S., now recorded as California’s fourth-largest ever.

As reported by Reuters, the Park Fire, burning approximately 100 miles north of Sacramento, started on July 24 and has since scorched over 400,000 acres.

Despite some thunderstorms, there was little relief for firefighters facing 100-degree Fahrenheit heat and 25 mph winds.

Christopher Young, a spokesperson for Cal Fire, said: “We had some thunderstorms that just brought us down-drafts, that’s a problem. Lightning is a factor we worry about.”

Impact of the Park Fire on communities

The fire, allegedly started by an arsonist, has destroyed more than 560 homes and structures, prompting the evacuation of over 4,000 residents.

A 42-year-old man has been charged with arson and is being held without bail.

One evacuee, Jim Young of Red Bluff, spent eight days at a wilderness trailhead with his dog.

He shared: “We just found out we can go home. Our property is safe. So many lost everything. But me and Sparky can go home now.”

Challenges in containing the wildfire

The rugged terrain in the affected area makes it difficult for firefighters to reach the fire lines, sometimes taking up to three hours.

Helicopters are being used to transport firefighters and supplies to the front lines, where some will stay for days to combat the blaze.

The Park Fire was 27% contained as of Saturday.

The intense wildfire season has raised concerns about stretching firefighting resources thin, prompting the National Interagency Fire Center to request assistance from Australian and New Zealand firefighters, who are set to arrive on August 7.
