Reduced number of flights may decrease prediction accuracy

The National Weather Service has been releasing weather observations at over 100 sites across the country for decades, operating like clockwork in the Pacific and Caribbean.

Meteorologists launch balloons equipped with radiozond devices twice a day at 8am and 8pm ET. These balloons rise about 15 feet every 2 hours, collecting data on temperature, humidity, and wind speed as they ascend through the atmosphere. The data is transmitted back using radio waves.

When the balloons reach a certain altitude, they pop and descend back to Earth with parachutes, completing their mission. The data gathered from these balloons is crucial for feeding into weather models that form the basis of forecasts in the United States.

However, many of the launch sites have been impacted by staffing cuts under the Trump administration, leading to reduced launches and restrictions. Meteorologists and experts are concerned that these changes will compromise forecast quality and increase risks during severe weather events.

The cuts in balloon launches are part of a broader downsizing effort across federal agencies. The National Oceanic and Atmospheric Administration, which includes the National Weather Service, has seen significant staff reductions and budget cuts.

Recent announcements about balloon launch suspensions in various locations across the country have raised concerns among meteorologists. These cuts could have implications for weather forecasting accuracy, particularly in regions prone to severe weather events.

Weather balloons play a critical role in providing high-resolution data on atmospheric conditions, which is essential for accurate weather modeling. Without this data, forecasters may struggle to predict events like storms and precipitation types.

Private companies are attempting to fill the gaps left by the National Weather Service cuts, but it is unlikely they will fully replace the services provided by NOAA. These companies are looking to expand coverage and enhance existing data collection efforts.

The impact of these cuts on weather forecasting remains to be seen, but there is concern among experts that forecast accuracy could suffer without the crucial data collected by weather balloons.

Elon Musk’s Prediction Comes True: Electric Vehicle Sales Begin to Slow Down in the Automotive Industry

ERon Musk became the richest man in the world by evangelizing electric cars and delivering one million electric cars. But in recent months, his company Tesla has struggled to maintain its momentum. This year's sales have declined and stock prices have fallen.

These struggles are emblematic of the broader situation facing the electric vehicle (EV) industry. The pace of sales growth has slowed after years of the coronavirus pandemic that sent demand and valuations soaring. The industry is entering a new phase, raising questions about whether the switch from gasoline and diesel to cleaner electricity will face a nasty stall or a temporary speed bump.

Musk acknowledged the difficulties this week, telling investors: “Globally, EV penetration is under pressure, with many other automakers pulling back from EVs and pursuing plug-in hybrids instead. ” he said. Musk, of course, insisted it was the wrong decision.

However, sluggish sales are a reality. Tesla and its closest rival in electric car sales, China's BYD, have both reported declines in electric car sales. Across Europe, the share of sales of battery electric cars fell to 13% from 13.9% last year, while sales of hybrid cars, which combine a battery and an internal combustion engine, rose to 29% from 24.4%. In the UK, electric cars accounted for 15.5% of total car sales in the first three months of 2024, only a slight increase on the same period last year.

In recent years, electric car manufacturers have been able to easily sell every electric car they make. However, many companies around the world are currently struggling to cope with the end of the era of rock-bottom interest rates, when households have less money left in their pockets.

“The economic headwinds are pretty bad across the board, so it's no surprise that the economy is slowing down,” said Ian Henry, whose auto analysis consultancy works with several automakers.

Buyers still have to pay more upfront for battery cars (though most will save money by owning an electric car because energy is cheaper). Additionally, electric vehicle repair costs and insurance premiums may be higher in some locations due to a lack of mechanics. Another important factor is that the rollout of public chargers has been very patchy, giving some potential buyers pause. All of these were pounced on by EV industry skeptics, turning the industry into a culture war battleground.

government's hand

Rico Luhmann, senior sector economist for automotive at investment bank ING, said EV sales had reached a “plateau” and that after an initial rush of early adopters accustomed to switching from gas-powered cars, electric vehicle sales were on the rise. He said sales will become even more difficult. diesel.

But there is more at play in this showdown than purely economic factors. Government also plays a big role. This trend is particularly evident across Europe, where EV sales are following diverging paths even as buyers face similar pressures. Norway is an outlier. Electric vehicle sales are heavily subsidized and EVs currently account for 90% of the market. This year, EV market share also expanded in Denmark, Belgium, and France.

However, in Germany, once the largest electric car market, the adoption rate of electric cars has declined simply because the government has ended subsidies.

Regulations not only affect demand but also play a large role in the cars sold. Matthias Schmidt, a Berlin-based electric vehicle analyst, has long predicted that European electric vehicle sales growth will slow in 2024. The reason is that January 1, 2025, is the date when the EU will take the next big step towards zero-emission vehicles, meaning lower average carbon emissions. The carbon footprint of the cars sold by each manufacturer must be reduced by 15% compared to 2021.

Therefore, this rule is a big incentive for automakers to focus their efforts on electric vehicles next year. Schmidt argues that the European industry is experiencing a “replay” of the situation experienced in 2019 when manufacturers held back sales of electric cars before mass-launching new models in 2020.

Sure enough, automakers are releasing new mass-market models at just the right time. Renault's electric 5 hatchback will cost less than €25,000 (£21,430) when it goes on sale this autumn, while Ford plans to launch an electric version of Britain's best-selling car, the Ford Puma, later this year.

Stellantis, which owns the Vauxhall, Peugeot-Fiat, and Chrysler brands, is also joining the rush, unveiling the Vauxhall/Opel Grandland electric SUV on Tuesday. Still, the company's CEO, Carlos Tavares, complained bitterly about how regulations are encouraging the switch to electric cars.

This week, he slammed Britain's Transport Secretary Mark Harper over the government's zero-emission vehicle (ZEV) mandate, which forces car manufacturers to increase the proportion of electric vehicles they sell. He later told journalists that the mandate was a “terrible” policy because it would force automakers to introduce electric models too quickly.

“The result of this is that everyone starts pushing BEVs (battery electric vehicles), pushing metals into the market, completely destroying profitability and destroying businesses,” he said.

Schmidt said the automakers’ complaints could have ulterior motives. EU rules will ban the sale of most internal combustion engines by 2035 but are expected to be revised in 2026.

“Many manufacturers are now complaining that it's unrealistic to meet these goals, but that's lobbying by stealth,” Schmidt said. “They do it so often that it's almost like a boy-werewolf affair. There’s definitely an ulterior motive to their moans.”

But other manufacturers have already delayed that shift, which means extending the sales period for still-profitable gasoline models. In the United States, General Motors postponed production at a plant in Michigan last year, and Ford also postponed construction of a plant in Kentucky. And in the UK, luxury car maker Bentley announced last month that it would postpone the launch of its first battery car by one year, until 2026.

“Manufacturers are definitely struggling strategically at the moment,” Luhmann said. “They're playing around with the timing of the model right now, but they're not delaying it too much. If they don't, they're going to miss out in terms of market share.”

Perhaps the biggest reason why European and American automakers are unlikely to switch gears toward EVs is China. China sales growth may have slowed in the first quarter of 2024 compared to a year ago, but still exceeded 1 million units, according to industry data cited by Reuters. Many Chinese automakers, including leader BYD and cash-rich new entrants such as mobile phone maker Xiaomi, are fighting to dominate their home market and capture a new role as the world's biggest car exporter. There is.

During a recent visit to China, German Chancellor Olaf Scholz spoke out against protectionism, keenly aware that imposing penalties on Chinese EVs would lead to swift retaliation against German automakers, but that Chinese manufacturers remain He said there needs to be access to the market.

Massive competition is fierce for electric car makers, with even Tesla having to cut prices to keep selling its cars. The competition will give auto industry executives sleepless nights and could force some companies to face mergers or bankruptcies, causing job losses. But prices could fall even further, making electric cars cheaper than gasoline cars.

“This is potentially good for consumers,” Ian Henry said. “Whether that's a good thing for manufacturers who are trying to make a profit is another question.”

The impact of climate change on food costs: A prediction of rising prices and worsening conditions

Food prices are on the rise

Because of global warming, you are already paying more and more for groceries. And rising temperatures will cause food prices to rise significantly over the next decade.

By 2035, rising temperatures alone are expected to increase global food prices by 0.9 to 3.2 percent each year, according to a study conducted in collaboration with the European Central Bank. This would increase the overall inflation rate by 0.3 to 1.2 percentage points.

“We are often shocked and surprised by the magnitude of these effects,” he says. Maximilian Kotz He mentioned discussions he had with economists during his research at Germany's Potsdam Institute for Climate Impact Research.

Abnormal weather due to global warming Increasingly impacting food production around the world And if farmers don't adapt, the losses will become even more severe as the world continues to warm.

To find out how this is affecting food prices, Kotz and his colleagues looked at monthly price data for a variety of goods and services for 121 countries from 1996 to 2021 and the exposure to which those countries were exposed. The weather conditions were compared.

Researchers looked at the correlation between food prices and factors such as average monthly temperatures, temperature fluctuations, droughts and extreme rainfall. They found a strong association between average temperature and food prices a month or so later.

Areas north of 40 degrees latitude, such as New York City, Madrid, and Beijing, experienced warmer-than-average winter temperatures, leading to lower food prices. But not just in the summer, temperatures in other parts of the world have always been above average, causing food prices to rise.

Moreover, the impact on prices is long-lasting. “If prices go up based on one of these shocks, they stay high for at least the rest of the period,” Kotz says.

The study didn't look at why prices have increased, but one possible explanation is that extreme heat is reducing yields, he said. “The vines may be dry when the crop should be harvested.”

Kotz said factors such as extreme rainfall had a smaller impact on food prices than average temperatures. This may be because flooding tends to be localized, whereas above-average temperatures can be very widespread.

Other studies have reached similar conclusions, Kotz said. But his team went a step further and investigated how food prices would change based on increases in average temperatures in climate model projections. Under the team's worst-case emissions scenario, global food inflation due to climate change will exceed 4% per year by 2060. However, the team believes the 2035 prediction is more reliable, as many other factors could have changed by then.

“There are a lot of things that could happen that will change the way the economy responds to climate change,” Kotz said. For example, inflationary pressures would be reduced if farmers adapted their practices to better cope with rising temperatures. But so far, he says, there is no sign that farmers are adapting.

“I think these are realistic predictions. They are based on solid empirical evidence.” Matin Kaim At the University of Bonn, Germany. “We need to recognize the fact that climate change poses new and major challenges to food and nutrition security.”

according to Food Price Index of the Food and Agriculture Organization of the United Nations, The cost of food fell in real terms between 1960 and 2000, but has risen since then. Russia’s invasion of Ukraine in 2022 caused a massive surge – factors that influence this Protests are occurring in many countries. The index price has since fallen, but remains higher than before the invasion.

Like the US Federal Reserve and the Bank of England, the European Central Bank aims to: keep inflation around 2%. Rising food inflation will make achieving this goal even more difficult, Kotz said.

AI Death Calculator: Highly Accurate Prediction of Your Time of Death

This is a matter of life and death – no doubt about it. bot it.

Most people aren’t in a huge hurry to know when the big bite is going to bite, but a newly developed AI death calculator can now predict when a person will die with eerily accurate accuracy.

“We use the technology behind ChatGPT (what we call the Transformer Model) to analyze human life by representing each person as a series of events that occur in their life,” December 2023. said Sune Lehmann, lead author of the study.Predicting human life using a sequence of life events” he told the Post.

In their report, the professor of networks and complex systems at the Technical University of Denmark and his co-authors describe a method known as “life2vec,” which uses selected details of an individual’s life, such as income, occupation, place of residence, and health history. Introducing the algorithm that can be used. Determines life expectancy with 78% accuracy.

“We take advantage of the fact that human life in some ways shares similarities with language,” Lehman explained. “Just as words follow one another in a sentence, events follow one another in human life.”

It’s a little different than ChatGPT. It’s the ever-popular bot that tech wizards are employing to land their dream job or curate the perfect outfit. By closely examining a man or woman’s past, life2vec can calculate the outcome of that person’s life.

“This model can predict almost anything,” Lehman told the Post. He said his research team also uses this specialized program to predict people’s personalities and international movement decisions.

“We predicted death because that’s what people (insurance companies, for example) have been doing for years,” he added. “So we were very aware of what could happen.”

Researchers fed detailed facts about a person into an algorithm that determined whether that person would survive at least four years after January 1, 2016. adobe stock

From 2008 to 2020, Lehman’s team studied a heterogeneous population of 6 million Danes of different genders and ages. Analysts used life2vec to identify participants who were likely to survive at least four years after January 1, 2016.

“The scale of our dataset allows us to represent individual human life trajectories at the sequence level, providing a detailed representation of how each person moves over time,” the report said. is written. “We’re looking at how an individual’s life evolves across different types of events (information about heart attacks mixed with information about salary increases and moving from urban to rural areas). You can observe it.”

Researchers used plain language such as “In September 2012, Francisco received 20,000 Danish kroner as a guard at Elsinore Castle” and “Hermione followed in her third year at secondary boarding school.” was used to enter AI-specific information about each study participant. 5 elective classes. ”

We then assigned different digital tokens to each piece of data, all of which were categorized very specifically. For example, a forearm fracture is represented as S52. Working in a tobacco store is coded as IND4726 and income is represented by 100 different digital tokens. And “postpartum hemorrhage” is O72.

Life2vec accurately calculated mortality predictions for a study population of 6 million Danes. adobe stock

life2vec used the information provided to predict who would die by 2020 almost perfectly over three-quarters of the time.

Research shows that factors that can contribute to early death include being male, having a mental health diagnosis, and working in a skilled occupation. Earning a higher income or holding a leadership role were both associated with longevity.

However, Lehman stressed to the Post that study participants were not given a prediction of death.

“That would be extremely irresponsible,” he said, adding that he and his team ultimately hope to share details of the results in a way that protects the privacy of study participants.

Lehman said once the algorithm is released to the public, it will not be used to make judgments against individuals. adobe stock

“But we can still learn from it [life2vec] What are the factors that might help people live longer?” Lehman said. “We haven’t delved too deeply into this, but this is another important application of the model.”

Currently, this bot is not available to the general public or businesses. And even if it were to be deployed at scale, this AI would not be used to notify specific individuals in cases such as writing insurance policies or making hiring decisions. Probably not, says Prober.

“Forecasting is not used for anything,” Lehman argued. “The point of life2vec is to understand what is predictable and what is not.”
