Phoenix's October heat wave is "unprecedented"​



Phoenix is in the throes of an unprecedented heat wave expected to last at least until the end of the week.
Reality check: Our summers have always been hot, but recently they've been feeling longer, too.

  • National Weather Service Phoenix meteorologist Ted Whittock said the Valley broke more heat records in the summer shoulder season — spring and fall in the past several years.
The big picture: Sky Harbor recorded 113° on Tuesday — the first time on record we've hit 110° in October.

  • Before this year, the latest we'd ever seen 110° was Sept. 19, in 2010.
Between the lines: Research shows climate change is causing heat waves to be more intense, longer-lasting and more frequent.

Stunning stat: The average monthly temperature this September was 94.6°, more than 2 degrees higher than the previous September record set in 2001.


What are we doing to ourselves?
 
Usual science deniers will be here soon talking about some bullshit.

We're now living with the consequences and they still propagate their lies.

When the fossil fuel industry funded science denialism in order to make sure Governments didn't actually move away from Fossil Fuels I don't even think they knew that there would be hordes of imbeciles who would create their own convents of pseudoscientific bullshit and make it basically their whole personality to deny science.

It's incredible.

But ah well, we had a good run as a species, I know they love to use "alarmism" as a one size fits all hammer to those who sound the alarm but if you look at where we're heading, we're gonna make life pretty difficult on this planet for us to continue in a meaningful way and progress.

Think refugee crisis has been bad this last 10 or so years... Just you wait.
 
Similar situation in California.
SF was in the 90's this week.
Very rare occurrence, especially in October.

Nothing good temperature wise, anyway.
Any baby steps we've made to reduce CO2 emissions won't have an effect on CO2 levels for decades.
The world will just have to deal with the negative effects as they occur.
 
The yeasayers will say anything whether or not it is scientific.

Specific weather events are not evidence of climate change. Climate change is proved over years and decades of measurements, not by a heat wave.

While individual weather events do not “prove” human-induced climate change, they are indeed EVIDENCE of it, especially when they are more frequent or more intense than in the past. Thus the fact that we are seeing more often and more intense heat waves and other intense weather events throughout the world is indeed evidence. Who thought that a hurricane could destroy a town hundreds of miles inland until one became so strong from increased warmth in atmospheric and gulf water that it did indeed happen.
 
Yes, there are peer reviewed papers that claim the Urban Heat Island Effect can make population centers as much as 10C (19F) warmer than the land away from the UHIE.

The reality of heat related injuries and fatalities is real. But this amount of warming over normal is the cause of the UHIE.

Note, they always specify cities where people are dying of beat.

One heat wave isn't really indicative of anything. Several record breaking heat waves in rapid succession that can only be cause by human activity is a problem.

No bullshit. Just the facts.

That is the side of the IPCC et. al. with the lies. The urban Heat Island Effect is real, yet they wish to blame this on greenhouse gasses. The warming if greenhouse gasses is small compared to the UHIE.
You sound like a flat earther with such weal rationalizations.
Now you talk like Chicken Little.

Yet this is an annual press release, wherever we such higher than normal city temperatures.

The facts are undeniable. The temperatures in cities increase with population and density.
 
The United Nations advocates for sustainable urban planning and design, emphasizing green infrastructure initiatives to mitigate urban heat island effects and enhance the resilience and livability of cities globally. To address urban heat challenges, a study was conducted in Chennai, India, from April to June 2023. The study focused on assessing temperature dynamics on a building's terrace by comparing a well-maintained garden area with an exposed region. Temperature and humidity sensors were deployed in both the garden and exposed areas of the terrace, as well as within rooms beneath it, to monitor hourly temperature fluctuations. The findings indicate a significant reduction in internal room temperatures in areas with rooftop gardens, ranging from 4 to 11 °C, depending on the time of year and sun's position, compared to rooms with fully exposed roof configurations. Additionally, simulation studies were performed to validate these findings, suggesting that optimizing the distribution of soil beds and plant density across the roof could yield an additional temperature reduction of 3–4 °C, resulting in an overall difference of up to 14–15 °C. The study highlights the efficacy of rooftop gardens in providing cooling effects during daylight hours and maintaining temperature parity post-sunset. Through analysis of sensor data, the research elucidates the intricate relationship between green infrastructure and thermal comfort, offering insights for energy-efficient building design and resilient urban planning. The findings underscore the potential of rooftop gardens in fostering a more comfortable, energy-efficient, and sustainable urban living environment.​

Urban Heat Island (UHI) phenomenon concerns the development of higher ambient temperatures in urban districts compared to the surrounding rural areas. Several studies investigated the influence of individual parameters in the UHI phenomenon, on the other hand, an exhaustive study that quantifies the influence of each parameter in the resulting UHI is missing in the related literature. This paper proposes a new index aimed at quantifying the hazard of the absolute maximum UHI intensity in urban districts during the Summer season by taking all the parameters influencing the phenomenon into account. In addition, for the first time, the influence of each parameter has been quantified. City albedo and the presence of greenery represent the most important characteristics with an influence of 29% and 21%. Population density, width of streets, canyon orientation and building height has a medium influence of 12%, 10%, 9% and 8% respectively. The remaining parameters have an overall influence of 11%. These results are achieved by exploiting three synergistically related techniques: the Analytic Hierarchy Processes to analyse the parameters involved in the UHI phenomenon; a state-of-the-art technique to acquire a large set of data; and an optimization procedure involving a involving a Jackknife resampling approach to calibrate the index by exploiting the effective UHI intensity measured in a total of 41 urban districts and 35 European Cities.​

It's getting too hot for me that's for sure! I'm in the process of packing up a pod and moving back east somewhere to cooler pastures. I'm sick of dripping from heat in mid Oct. This is ridiculous! Don't get me started on the dust overload from the lack of ground cover. Yikes, this place won't last long.

Yeah, it's an annual press release, and it's a bad thing. If the oven has been slowly heating up by a degree a year and recent activity have been steadily and rapidly heating up the oven by 10 degrees and the news have been reporting on it.

Are you denying the science of the Urban Heat Island Effect?

Are you denying that it is currently 103F in Sells, AZ, which is not an urban area?

The UHIE is not exclusive to what we class as "Urban." The effects are just more prominent as the population and percentage of capped off land increases.How much vegetation loss do you think there is, that no longer provides evaporation cooling?

All population centers experience the UHIE.



How much lower is the water table that also provided less evaporation cooling and it gets lower? We have known for decades that we are pumping out water faster than it replenished.

We are the cause, no doubt. But you guys discount the variables that have the largest effect so you can blame CO2.
 
This is Arizona. The amount of vegetation hasn't changed since 1912.
 
MAGA/people denying climate change better be PRAYING that climate change isn't real and that humans don't contribute to it because if it's real and we contribute then THEIR OWN KIDS/GRANDKIDS/GREAT GRANDKIDS WILL ****ING HATE THEM.

Which they may already do.

Sure it has. At the time, very few people lived there. That's about the time it began as a town.
 
Yawn

Inciting MAGA means you have nothing valuable to say. Only thoughts of slander, as if that is the cause.

Correct. Not sure what your point is. Its population topped out at 2,799, and there are no lawns. Houses, dirt, and scrub.
 
Yes we are living in the consequences of no holds barred capitalism, much like the third world has for decades.
 
Yeah even as far north as Ohio this summer has been pretty unbearable.
 
We could just ditch the whole neoliberal project.
