Hottest large city in US broke previous heat record from 1993 as temperatures are expected to reach 110 tomorrow

 

Phoenix, Arizona, saw its 100th straight day of 100F (37.7C) heat this week.

The hottest large city in the United States broke its previous record of 76 consecutive 100F days set in 1993. The relentless streak, which started on 27 May and hit its 100th day on Tuesday, is forecast to persist into next week. An excessive heat warning is in effect through Friday, with temperatures expected to reach 110F (43C) tomorrow.

This summer was the hottest one in Phoenix since 1896, when records first began. Latest county data shows that at least 177 people died from heat-related causes so far this year, with 436 under investigation. Last year, Maricopa county saw 645 confirmed heat-related fatalities, enduring 55 days in a row with above 110F temperatures.

“Summers in Phoenix are becoming increasingly hotter, with more intense and prolonged heat,” said Shel Winkley, a meteorologist at the non-profit Climate Central. “On average, Phoenix now experiences about 60 days [or] 65% of the summer with extreme heat.”

In addition to Arizona, millions of Americans across Nevada and California are facing scorching heat, with the highest temperature expected to peak in the Death Valley national park at 120F (49C).

“Temperatures will be running up to 8 degrees above normal for early September,” the National Weather Service Las Vegas office warned in an advisory.

Homeless people, children, the elderly, pregnant people and those with chronic medical conditions are at higher risk for heat-related illness.

 


“Consecutive high heat days mean that people in Phoenix don’t get respite at night, especially those who don’t have or can’t afford to run an AC unit as well as those who work outdoors,” said Juan Declet-Barreto, senior social scientist for climate vulnerability at the Union of Concerned Scientists.

“I would like the public to understand that this heat is no longer a rare occurrence,” Declet-Barreto said. “It will continue to get worse year after year if we don’t make drastic emissions reductions. We need to decarbonize our energy, industrial, agricultural and transportation sectors. There’s no way around that if we want cities like Phoenix to be livable.”

 Park fire scorches 386,000 acres as firefighters battle blazes across US west, including historic mining town of Havilah

The largest wildfire in the US swelled to more than 380,000 acres (154,000 hectares) on Tuesday morning, an area bigger than the city of Los Angeles and three times the surface area of Lake Tahoe, as thousands of firefighters battled the blaze in a remote wilderness area in northern California.

Meanwhile, the destruction caused by wildfires raging across the US west came into sharp focus as photographers documented the destruction left by the Borel fire in southern California. The fast-growing fire tore through the historic mining town of Havilah, leaving burnt buildings, cars and forests.

 

About 2,000 people were ordered to evacuate because of the fire, which burned through the Sequoia national forest. By Tuesday morning, the fire had torn through more than 57,000 acres (23,000 hectares) and was 17% contained.

No fatalities have been reported.

 In northern California, more than 5,500 firefighters were working to contain the Park fire, the largest wildfire in the state this year, which has moved up the ranks to become the fifth largest in the state’s recorded history.

By Tuesday afternoon, the fire had scorched more than 386,000 acres, according to the California department of forestry and fire (Cal Fire). It has destroyed more than 190 structures and is threatening 4,200 more.

After several days of intense firefighting efforts, crews had reached 14% of containment on Tuesday morning amid cooler temperatures and more humidity, but the fire continued to burn very actively, Cal Fire said. With the steep terrain, wind activity and many areas inaccessible to crews, the fire is making uphill runs and spot fires continue to occur, the agency said.

The massive fire continues to burn through rugged, inaccessible terrain with dense vegetation, threatening to spread to two other counties. “That’s going to be a continued challenge for us moving forward over the next couple of days,” said Mark Brunton, an operations section chief with Cal Fire.

Cooler weather has helped firefighters stop the blaze’s path near some communities like Forest Ranch, where some people began returning to unscathed homes on Tuesday.

Christopher and Anita Angeloni have lived in the community of 1,600 for 23 years, and have had to evacuate several times due to wildfires, including the 2018 Camp fire, which killed 85 people and decimated the nearby town of Paradise.

Christopher Angeloni said he constantly worked on creating defensible space around his home and was happy to return home nearly a week after evacuating to see his hard work paid off.

“We were prepared to possibly lose everything,” he said.

Anita Angeloni said it has been a stressful week. “We have not been sleeping enough, very tense, praying all the time, teary eyes,” she said. “But we’re here. We’ll see for how long.”

The man arrested on suspicion of starting the blaze by pushing a burning car into a gully made his first appearance in court on Monday and was charged with felony arson of an inhabited structure or property.

Ronnie Dean Stout was arrested at his home in Chico a day after the fire started. Prosecutors said Stout had a previous criminal record and would face life in prison if convicted.

The Butte county district attorney, Michael Ramsey, told reporters after the hearing that Stout said the incident was an accident, the Sacramento Bee reported.

 

The district attorney said during a press conference that Stout was seen drinking at a swimming hole in the area before the fire started and drove “recklessly” through the area before the car went over a berm. Witnesses reported hearing the sounds of an engine revving and scraping.

“The indication is he didn’t purposely light the car on fire because he was trying to get out of being stuck on the edge of a berm,” Ramsey said, according to KQED. “We have another witness who saw dirt and smoke coming up, then followed immediately by smoke. Then fire. There’s an extraordinary amount of dry grass.”

The Park and Borel fires are two of more than 100 blazes active in the US west. Evacuation orders were in effect on Monday on 25 wildfires, according to the National Interagency Fire Center. More than 27,000 wildland firefighters and support personnel are deployed.


Some blazes were sparked by the weather, with the climate crisis increasing the frequency of lightning strikes as the western US endures blistering heat and bone-dry conditions.

In Colorado, the Alexander Mountain fire doubled in size between Monday and Tuesday to more than 1,800 acres, according to the US Forest Service. The blaze, about 12 miles (19km) west of Loveland, Colorado, where the Rocky Mountains fold into the Great Plains, spurred mandatory evacuation orders and produced a looming column of smoke that could be seen for miles.

 

In Oregon, the 2024 wildfire season has burned more than 1.2m acres so far, according to the State of Oregon Fires and Hotspots Dashboard, a total that surpasses the size of the entire state of Rhode Island.

The state’s largest wildfire, the Durkee fire in Baker county, has burned nearly 300,000 acres and is more than 50% contained.

“Although yesterday’s rain was beneficial,” a Tuesday update from fire officials read, “it was not enough to extinguish heat on the fire.”

Pakistan ‘It is beyond bleak’: Pakistan floods affecting 16m children, says Unicef

 Devastating conditions were triggered by heavy monsoon rains that have so far killed more than 1,500 people

All four of Haliman’s daughters have fallen sick after she left her flood-ravaged house in her village in Qambar Shahdadkot district in the Sindh province of Pakistan. Two of her daughters have a recurring fever and two have skin diseases.


“I have never seen such diseases. The skin on my eldest daughter’s feet is peeling off,” said Haliman, sitting on a charpoy in a girls’ college in Larkana, where she had sought refuge along with a hundred others. “It is because of the floods and she waded through the flood water with me for hours. It is not only her feet, but her back, thighs and neck have bumpy rashes.”


Devastating floods in Pakistan triggered by heavy monsoon rains have killed more than 1,500 people, including 528 children, and affected about 16 million children, according to Unicef. Authorities say the waters that have washed away homes, roads, crops, livestocks and people will take at least three to six months to recede.


Floods have also brought water-borne diseases. “Millions of people are living under the open sky,” the Pakistani prime minister, Shehbaz Sharif, told the Shanghai Cooperation Organisation summit in Samarkand, Uzbekistan, last week. “Water is giving rise to the water-borne diseases.” He has urged the world to focus on the impact on children.


Haliman said her daughters are suffering. “The skin diseases are getting worse and the fever of my daughters is also not going down. I am not getting any reasonable treatment here.”


At least 3.4 million girls and boys remain in need of immediate, lifesaving support. Unicef Pakistan’s representative, Abdullah Fadil, warned that without a massive increase in support, many more children would die. “The situation for Pakistani families is beyond bleak, and malnourished children are battling diarrhoea and malaria, dengue fever, and many are suffering from painful skin conditions,” he said.


Rawat Khan, 47, holding her daughter Iqra, whose ear became discoloured and blemished with small, pus-filled spots, said these diseases were not common before but now all the children were getting sick. Her son’s chest was swollen too.


“The doctors are asking us to get tests done in Karachi … but we cannot afford that. We don’t have money. We lost our houses and savings in the floods,” she said.


“We only saved our lives. We could save nothing else. We are helpless to see our children falling sick and we are unable to do anything about it. The government has failed us.”


Zeeshan Chandio, who comes from an affected village in Sindh province, held his son Nadeem in his arms. “I too want help and I don’t know what’s wrong with my son. His stomach is not well and belly is swollen.”


Dr Faiq Ali, who arranged a medical camp in Warah, a village in Qambar Shahdadkot, one of the most affected districts in Sindh province, said he saw more than 300 children on Sunday and all had various conditions such as malaria, diarrhoea and skin diseases.


“These all are water-borne diseases. You see standing water in the flooded areas where mosquitoes are rampant and people don’t have clean drinking water and they walk in the contaminated water and drink the same water. Everything is so bleak,” Ali said.


He added that a large part of the population was affected and this was on a large scale.


“Sadly, the government is not active in a way that it should be as we have not seen such disasters before. The National Disaster and Management Authority is also not playing an active role. We will see a bigger disaster in the shape of diseases in near future if the government stays inactive,” Ali warned.


Many flood-affected victims in Larkana said they were living in the constituency of the foreign minister, Bilawal Bhutto Zardari, and he had not visited them. They asked for his help for their children.


Jaffarabad, one of the most affected towns in Balochistan, which along with Sindh are the worst-hit provinces, represents the same bleak image where children are falling sick.


A woman, who requested anonymity, consoled her child in her lap. “We don’t get medicine, treatment, food or anything for our children. My son has been vomiting for days but I don’t know the cause of his sickness,” she said.


Fadil said that Pakistani children were paying the price for a climate disaster that was not of their own making and the world should help them so they could rebuild the lives of millions of vulnerable children in the coming months.


“Apart from rise in diseases, education for children is our main concern,” he said. “In 81 calamity-hit districts, the children are missing schools and even before this disaster in Pakistan more than 50% children are out of school.


“We don’t know when they will go back to school and that’s worrying and particularly for girls in these districts, whether their parents will send them to school or get them married. In Pakistan, early marriages are nothing new.”


Zeeshan Ahmed Khan, nine, was studying in grade 3 when his school was flooded with water. “I got new books when the new session started but they got damaged in the flood,” he said.


Allah Warayu had just moved to 4th class when half of his school was drowned in water. “I miss school and my friends but I have no idea where they are. Only my cousin is here with me and I have no idea where and how my other classmates are,” he added.


Fadil said he had seen girls reading and studying in tents and camps for the first time in their lives.


“I have seen young girls who, for the first time in their lives, hold pencils and books in their hands in the tents. They asked us to continue it. This was the most powerful and joyous thing I had seen. It must continue it and make sure all girls and children go to school.”

Uma série de fortes tornados atingiu o sudeste dos Estados Unidos e varreu o que encontrou pelo caminho em pelo menos cinco estados. Há dezenas de mortos, segundo informações da imprensa americana.

O presidente americano Joe Biden determinou que recursos federais sejam direcionados imediatamente para os locais mais necessitados, afirmou a Casa Branca neste sábado (11).

Em Kentucky, um dos estados mais atingidos pelos tornados, 70 mortes já foram confirmadas, mas Andy Beshear, governador do estado, diz que o número de vítimas pode superar 100.



"Esse vai ser um dos piores danos provocados por tornados que nós vimos em muito tempo", afirmou Beshear em uma entrevista à televisão local WLKY. Ele declarou estado de emergência e ativou a guarda nacional para auxiliar no socorro das áreas afetadas.


Na cidade de Mayfield, uma fábrica de velas estava em operação quando foi atingida pelo tornado. Segundo a WLKY, mais de 100 pessoas que estavam no edifício estão sendo resgatadas.

"Mayfield será o marco zero", disse o diretor de gestão de emergências de Kentucky, Michael Dossett, à rede CNN. "A cidade levou o pior golpe. Há uma devastação em massa", acrescentou ele, segundo a agência AFP. Um toque de recolher para as 19h foi imposto na cidade, de acordo com a polícia.




No Tennessee, o clima extremo matou ao menos três pessoas até a manhã deste sábado, segundo um representante da agência de emergência estatal.

Em Arkansas, o tornado destruiu o telhado de uma casa de repouso, matando ao menos uma pessoa e ferindo outras cinco, afirmou o juiz do condado.

Em Illinois, o tornado derrubou boa parte de um armazém de distribuição da Amazon, onde dezenas de pessoas trabalhavam no turno noturno, processando milhares de pedidos antes das festas de fim de ano. Seis mortes foram confirmadas pelas autoridades locais

O chefe de polícia local disse à imprensa que cerca de 50 pessoas estavam no depósito da Amazon quando ele foi atingido pelo tornado por volta das 20h30 da noite de sexta-feira (10).




Segundo a Deutsche Welle, no estado de Missouri, uma pessoa morreu e outras duas ficaram feridas em desabamentos de edifícios.

O chamado "tornado quádruplo" foi mais forte e longo para esta época do ano (Incomum Tornados nessa época), conforme especialistas consultados pelo "Washington Post".


De acordo com o site poweroutage.us, mais de 290 mil consumidores em seis estados estavam sem energia elétrica na manhã deste sábado (11).

LONDON – Climate change could be about to alter life in the sea, according to new research in Nature Geoscience.

By Tim Radford, Climate News Network
Researchers at the University of Southern California have been experimenting with common microbes, hoping to predict which will flourish in a warmer and more carbon dioxide-rich atmosphere.
The microbes are two genera of cyanobacteria. These tiny creatures – blue-green algae responsible for huge occasional “blooms” in the sea – are life’s bottom line: they fix nitrogen from the atmosphere and they photosynthesize atmospheric carbon to release oxygen, so they deliver staples for survival both for all plants and for all animals.
These microbes are everywhere. U.S. researchers recently charted the predicted change in cyanobacteria populations in the arid soils of the North American continent over the next century: now this second team has begun to look at life in the sea.

David Hutchins and colleagues studies two groups of nitrogen fixers; Trichodesmium andCrocosphaera: the first forms vast and often visible colonies, the second is harder to see, but is found everywhere.
They tested seven strains of the two microbes, from different locations in both the Pacific and the Atlantic Oceans, under laboratory conditions in artificial atmospheres that mimicked the predicted carbon dioxide concentrations under various climate scenarios.
The researchers found that as carbon dioxide levels rose, nitrogen-fixing productivity rose too, by up to 125 percent. But the responses varied according to the strain under test: some did better under pre-industrial conditions; some flourished as they neared the levels predicted for a “greenhouse” world.
The research demonstrates what any evolutionary biologist would have predicted: that environmental conditions “select” for particular species with the appropriate adaptations, and that as conditions change, so do populations. What it means in practical terms for the rest of the planet is less certain.
This is basic research which exploits the university’s large “library” of marine microorganisms, and establishes a baseline of data that will give some guide to ocean productivity in the future, but quite how it will affect the marine food chain – and oceans cover 70 percent of the planet, so it is a big question – is still to be established.
“Our findings show that CO2 has the potential to control the biodiversity of these keystone organisms in ocean biology, and our fossil fuel emissions are probably responsible for changing the types of nitrogen fixers that are growing in the ocean,” said Professor Hutchins. “And we’re not entirely certain how that will change the ocean of tomorrow.”

Prepare for 5°C Warmer World








Preparen-se para um Mundo 5 graus mais quente.

LONDRES - Pelo cientista, Sir Robert Watson | O mundo perdeu a chance de manter as emissões de gases do efeito estufa abaixo do nível necessário para evitar que a temperatura suba acima de 2 ° Celsius. De acordo com o cientista britânico, que usou para presidir o IPCC, o Painel Intergovernamental sobre Mudança do Clima. ( a perspctiva hoje, segundo o cienista é  de 5 graus Cº)

Um mundo de 5 ° C mais quente do que hoje poderia esperar-se colheitas caindo em países desenvolvidos (observe  seca de 2012 nos EUA) e em desenvolvimento, o aumento do nível do mar ameaçando muitas grandes cidades (New York, Santos, Rio, Balneário caboriú etc...)....







By Alex Kirby, Climate News Network

LONDON — The world has missed the chance to keep greenhouse gas emissions below the level needed to prevent the temperature climbing above 2° Celsius, according to the British scientist who used to chair the IPCC, the Intergovernmental Panel on Climate Change.

The scientist, Sir Robert Watson, chaired the Panel from 1997 until 2002, when he was
ousted after U.S. pressure for his removal. Watson said there is a 50-50 chance of preventing global average temperatures rising more than 3°C above their level at the start of the industrial age, but a 5°C rise is possible.

That would mean the Earth warming more than it has since the end of the last Ice Age. Speaking at a symposium at the London School of Hygiene & Tropical Medicine, Watson said:
"All the promises in the world, which we're not likely to realize anyway, will not give us
a world with only a 2°C rise. All the evidence, in my opinion, suggests we're on our way to a 3°C to 5°C world.

"Some people are suggesting that we try to geo-engineer our way out of the problem,
intervening in the climate system to moderate warming.

"I'm very, very nervous about that," he said "It shows a level of arrogance that we know how to manage our environment. It certainly needs a lot of research."

Watson concluded: "There are cost-effective and equitable solutions to address climate
change, but political will and moral leadership is needed, and the changes in policies,
practices and technologies required are substantial and not currently under way."

Watson told the Climate News Network: "We're going to have more people in the world and they'll be wealthier, so energy demand is bound to rise.

"We look like having huge quantities of gas from shale. That can be a useful transitional tool: it emits half the carbon you get from coal. But it's not a long-term solution, unless you can use it with carbon capture and storage, CCS. I'm optimistic that CCS can work, but it's got to be shown to work, and what costs and energy penalties it will entail.

"We now know we can't rule out a possible 5°C temperature rise, and we need to start
preparing for it.

"When I was chairing the IPCC we were all very optimistic that we'd have a global agreement to limit emissions, though we knew it would be difficult. But we were hopeful that emissions would not go up at the tremendous rate they are rising now."

A world 5°C warmer than today could expect falling harvests in developing and developed countries, sea level rise threatening many major cities, and significant water shortages. More species would be facing extinction (10 percent of species are thought to be at risk for every 1°C of warming), there would be more (and more intense) extreme weather, and a growing risk of abrupt and major irreversible changes in the climate system.

Watson was voted out as the IPCC's chair in 2002. The weekly New Scientist reported that the year before, shortly after the inauguration of U.S. president George W. Bush, an ExxonMobil executive wrote to the White House asking: "Can Watson be replaced now at the request of the U.S.?"

Watson is now science director of the Tyndall Centre for Climate Change Research at the University of East Anglia, UK, and chief scientific adviser to the UK Government's

Department of Environment, Food and Rural Affairs.

Sir Andy Haines, former director of the London School of Hygiene, told the Climate News Network: "We're not making much progress on climate change at the moment. We need more arguments combining environment and health – cutting coal-burning, for instance, improving access to clean energy, walking and cycling instead of using cars.

"We need to look not just at population, but at consumption in the developed countries. A lot of vested interests don't want to go down that road. We can change by paying for
externalities, like the adverse effects of air pollution.

"We can address the inequalities which are evident in areas like heart disease rates and diet. And we need to influence the UN's new sustainable development goals to include both health and environment indicators."

Extreme Weather Can’t ‘Surprise’ Insurance Companies


Severe weather has been clobbering insurance companies, and the headlines just keep coming. “Drought to cost insurers billions in losses,” said the Financial Times a few days ago. “Many U.S. hurricanes would cause $10b or more in losses in 2012 dollars,” the Boston Globe said about the latest hurricane forecasts. “June’s severe weather losses near $2 billion in U.S.,” said the Insurance Journal earlier this year.
This year’s extreme events follow the world’s costliest year ever for natural catastrophe losses, including $32 billion in 2011 insured losses in the United States due to extreme weather events. This is no short-term uptick: insured losses due to extreme weather have been trending upward for 30 years, as the climate has changed and populations in coastal areas and other vulnerable places have grown.

The U.S. insurance industry continues to be “surprised” by extreme weather losses. But the truth is that weather extremes are no longer surprising. Back-to-back summers of devastating droughts, record heat waves and raging wildfires are clear evidence of this. Last year’s crazy weather triggered near record underwriting losses and numerous credit rating downgrades among U.S. property and casualty insurers.
And in the face of a changing climate, such events can be expected to increase in number, and severity.  It’s time for insurance companies to recognize this new normal, and incorporate it into their business planning—for the sake of their shareholders, their industry’s survival, and the stability of the U.S. economy.
Ceres, a business sustainability leadership organization, has been researching the effects of climate change and severe weather on the insurance sector. In a report to be released next month, titled Stormy Future for U.S. Property and Casualty Insurers, we will detail our recommendations for insurance companies, investors and regulators to help strengthen the insurance sector so it can better weather the challenges ahead.
For insurance companies, using catastrophe models that can better anticipate probable effects of climate change on extreme weather events are key. And especially in vulnerable markets, insurers’ guidance on insurability should inform decisions that communities make on land-use planning, infrastructure decisions, and building codes.
Insurers can also encourage the transition to a low-carbon economy—one built to forestall the worst effects of climate change—by offering products and services that encourage clean and efficient energy, encouraging customers to adopt climate-change mitigation plans, and encouraging policymakers to act to reduce carbon pollution.
This would not be the first time insurance companies have helped change American society. By making insurance contingent on smoke detectors, insurers cut down on deaths and losses from building fires. By backing seat belt laws and including seat belt violations in rate calculations, they helped save lives on the road.
By engaging fully on climate change and energy policy—inside and outside of the boardroom – insurance companies can lead the way once again. It would be the right thing to do, both for their business, and for our future.
