Are environmentalists responsible for Californian forest fires? No. It was environmentalists (by which I mean people who professionally study forest ecology or environmental science) who have tried to convince the various agencies responsible for suppressing forest fires that forest fires are not necessarily bad but are instead a natural part of the West's ...

Without acknowledging any of the conditions actually present in the church, wood fires can get much hotter than 600 °C. The maximum temperatures measured within the pile were of the order of 800, 1000, and 1200 °C for piles composed of 1.27, 2.54, and 9.15 cm sticks respectively, although the maximum temperatures for a given size stick appeared, from ...

Yes. At Nogales, Arizona, in 2012, according to this story, found using Google Image Search: Nogales, Arizona, firefighters rushed to the international border with Mexico at Morley Avenue after a blaze broke out at the Hotel San Enrique in Nogales, Sonora, Mexico. The hotel had been a lodging for migrants waiting to cross illegally into the United States. ...

Probably yes: According to at least one expert, the temperature in the Notre Dame fire must have been extremely high, and probably exceeded 600°C. Yesterday the Süddeutsche Zeitung, one of Germany's most reputable newspapers, published an interview with the director of the German Technisches Hilfswerk (the Federal Agency for Technical Relief) and former ...

The first image is legitimate. It is of a Paradise CA neighborhood after the Camp fire raged through the town (KTVU). The third image definitely is not of Paradise CA. This image was used three months prior to the Camp fire in support of a conspiracy theory regarding the use of directed energy weapons in these fires (conspiracy theorist). Addressing the ...

Other examples? There's a list of buildings which have collapsed due to fire here: Historical Survey of Multi-Story Building Collapses Due to Fire. Scanning this document, to include only building which are made of steel (and not e.g. reinforced concrete), shows only two: Alexis Nihon Plaza Montreal, Canada Steel frame with composite steel beam and deck ...

Wood is a perfectly acceptable and common material used in metal forging even more so when it becomes partially combusted (charcoal). What really determines the heat though, is the amount of oxygen it can get. If there were medium-high winds blowing on the building it could have melted even steel beams.

Yes, they do share... but not specifically because of the fires or out of a sense of altruism. According to AFP Fact Check: University of Adelaide ecologist Dr. Michael Swinbourne told AFP via email on January 16, 2020: “Wombats will share their burrows with other animals at the same time. I wouldn't say that wombats are "happy" about sharing with other ...

The "truthers" own report claims that collapse due to fire was "improbable" because according to their estimation it would have required simultaneous heating of all support columns. However, according to experts' report(s) (i.e. Preliminary modelling of Plasco Tower collapse) (2018) what happened was that the reinforced concrete floors ...

The entire type of assertion "if X is burning, and X is said to burn at Y temperature, then the fire cannot melt Z which melts at Z temperature" is fundamentally flawed at at least two levels. The burning point of a material is the usual minimum point where it starts to burn, but not the maximum temperature of a fire involving that material. The temperature ...

The video in question comes from this webcam: Viewsurf: Cathédrale Notre Dame. This webcam only takes one 60-second video every hour, at 5 minutes after the hour (17:05, 18:05 etc). Here's a Youtube video which shows snippets recorded at 17:05, 18:05, 19:05 etc.: Viewsurf Notre Dame Webcam: 20190415 - 17:05 to 21:05. The flash occurs at 0:23. It's pretty ...

In short, yes. Reference #1: Recent history has seen an increasing trend of record-breaking wildfires on public forests and grasslands... Why so many large fires? “The most extensive and serious problem related to health of national forests in the interior West is the over-accumulation of vegetation, which has caused an increasing number of large, intense, ...

First of all, Google can find quite a lot of background on the dispute between Steve Lipsky and Range Resources Corp. This article is a summary of the situation, where Range Resources Corp. has been drilling for gas close to Lipsky's estate, after which Lipsky is blaming the company for ruining a well, from which he used to get his fresh water supply. It is ...

No The Plasco Building in Tehran On January 19. 2017, this 17-storey steel-framed building abruptly collapsed after burning for several hours, officially killing 20 firemen. https://www.youtube.com/watch?v=VTrUk9AECIs The Windsor Tower in Madrid This was a 29 storey building with outer steel columns and a concrete core. A strong mechanical floor was at the ...

No. The link is to an oil trading company, not a technical source, and the reference provides no source for the information. "Maximum burning temperature", is not a standard measure for specifying jet fuel. Jet fuel specifications from ExxonMobil list many requirements and test methods, but do not mention "maximum combustion temperature", or any similar ...

The answer to your headline question is yes, coal seams in the blue mountains are burning. But that has been the case for the last 6000 years or so as Mt Wingen (Burning Mountain) at the north end of the Blue Mountains has coal seams that have been continuously burning for that long. There are others which seem to have been burning at least since the sixties,...

I looked for research into this issue which was independent from the UL FSRI. In 1999, there was a Master of Engineering student's project report: Deborah L Palmer, Should bedroom doors be open or closed while people are sleeping? A probabilitic Risk Assessment, 1999 The aim of this research is to determine whether it is safer to sleep with bedroom ...

Mostly true First, your title somewhat overstates Reason's claim in the article "Bad Policies Fuel Fires", which is that "[politicians] and environmentalists increased the risk of big fires by opposing the thinning of forests." The article never claims overgrowth is the sole reason (or even the principal reason), just that it provides ...

Certainly UK fire regulations and analysis support this claim. Residential institutions are required to have automatic closers on bedroom doors because of this. On taller buildings there is a requirement to have a 30-minute-rated fire door on bedrooms because it gives sufficient time for help / to escape from a fire outside the bedroom rather than be ...

Not all of Brazil is Amazon. Year 2019 to 26 August, Brazil has had an 80% increase in satellite detected fire spots from the same period in 2018. For the Amazon portion of Brazil the increase over 2018 was 128%. The raw data for the whole of Brazil (01 January through 26 August) is: | Year | Amount | |______|_________| | 1998 | 39,197 | |...

The argument from the Freakonomics article is somewhat problematic. It seems to boil down to the idea that, given that other things such as building code changes must have improved in ways that prevent fire deaths since smoke alarms were widely adopted, shouldn't the rate of deaths have plummeted instead of continuing the existing downward trend? The first ...

I don't have any knowledge of this specific case, but according to the fire official quoted in this article, rescuing animals from burning buildings is a routine part of firefighting practice. I see no particular reason to doubt the present claim.

Pools of kerosene burn in a self-sustaining manner as reported in Combustion Properties of Large Liquid Pool Fires Fire Technology volume 25, pages 241–255(August 1989). This reference compiles kerosene pool fire data from 6 sources and spans the size range of 0.25 to 50 meter diameter pools. Quantitative data for burn rate in millimeters of depth per ...

Although it is hard to say for Quảng Đức specifically, it wouldn't be without any precedent, a famous similar case is that of Percy Shelley's heart, Mary Shelley's, his wife, carried the heart with her for the longest time. One of the most prominent hypothesis is that it was due to tissue calcification from a previous tuberculosis infection he had. ...

If you're looking for a historical answer, I don't have that, but if you're asking about the scientific side of it, the temperature of the weather is irrelevant to whether a fire could be sustained; the fire will produce heat that will raise the temperature above the flashpoint. The flashpoint of wood is 300 degrees Celsius, and clearly it can burn when the ...
