The police-tech giant Flock is announcing today that it will change officers’ access to its nationwide network of license plate readers, in an apparent effort to quell a growing backlash and win back contracts lost amid concerns about mass surveillance and police abuse.

Several changes aim directly at a problem that has made recent headlines: officers abusing Flock’s technology to stalk and harass current or former romantic partners. Flock’s 120,000 cameras form a nationwide network that police departments can use, giving officers access to an enormous pool of searchable location data. A recent Washington Post investigation found 46 cases in which officers were accused of using Flock’s cameras for unauthorized purposes like stalking.

To combat that, the company will start requiring officers to enter a criminal case number before conducting a search. The system was launched as an option last year but is now required. It’s meant to verify that each search has a legitimate purpose. 

This is a baseline standard that civil liberties groups have asked for, but officers have found ways around similar safeguards. The ACLU recently found that when Flock required officers to enter a reason for a search, some used generic terms like “investigation” or mocked the prompt entirely; at one Oregon department, officers entered “hehehe” 20 times. Because Flock won’t verify case numbers, officers could circumvent the new safeguard just as easily.

But Flock is now expanding an automatic auditing system that is supposed to catch those who try that, the firm announced today. The feature analyzes officer search activity and flags to administrators anyone with suspicious searches. This was also introduced as an option last year but is now mandatory. Flock has not shared specifics on how accurate the automatic auditing tool is, nor opened it up to independent evaluators.

Beyond trying to prevent officer abuse, Flock is making changes meant to address broader backlash about how much data its network collects and who can search it. The company now recommends that agencies hold onto data for seven days rather than 30 (though they can choose to overrule this). Departments can also now limit other departments’ searches of data from their cameras to those made for certain stated reasons; for example, they might allow investigations related to “kidnapping” but not for purposes of “immigration enforcement.” It’s another safeguard that depends on officers to accurately report why they’re conducting a search.

The changes come as a backlash against Flock has started to come from all angles. Tucker Carlson has said its technology is contributing to a “slave state.” Some cities have reportedly dropped Flock contracts because of such protest, though it’s difficult to estimate how many: In February, NPR found that at least 30 cities had dropped in the last year, but the activist group DeFlock puts the number higher. Some states or municipalities are passing laws to ban license plate readers altogether, while some that allow them are switching away from Flock to the other industry leaders, Axon and Motorola. Flock has said these cancellations represent a small number of the 5,000 agencies that have contracted with the company. 

Chad Marlow, a senior policy counsel at the ACLU who has become a sort of nemesis to Flock and other companies making automatic license plate readers, says the backlash is driven less by individual abuses—though those don’t help—than by the sheer scale of surveillance that Flock’s cameras enable.

“In America, you only get to investigate someone if you think they’ve done something wrong,” Marlow says. As license plate readers grow more ubiquitous, officers have increasing latitude to investigate people without first establishing suspicion of a crime, since searching the troves of data the readers collect does not require a warrant. He adds, “Is it worth it to catch a certain number of criminals, return a certain number of stolen cars, to eviscerate Americans’ privacy?”

Flock CEO Garrett Langley traces the backlash to a different issue. “If you look at the main reason we’ve lost customers, it’s misinformation,” Langley told MIT Technology Review. He says people mistakenly believe Flock does facial recognition or sells the data it collects to commercial buyers. (The misinformation charge cuts both ways, however; the ACLU and other critics have published accounts of the company repeatedly lying to city councils and other decision-makers about what its technology can do.)

Though the company has taken steps in response to public concerns, “our change in stance is more of one from building things that are optional,” Langley says, to “building more confidence that as a technology company we have a responsibility to enforce guardrails, not provide optionality.”

Flock’s new rules are undeniably small and incremental compared with what the ACLU has advocated. Marlow is broadly supportive of them but notes that judging whether they reduce abuse would require the company to open its systems to independent researchers for the first time rather than citing internal studies. 

More broadly, though, he says the backlash is putting the company at a crossroads.

“Flock has come to the table because this incredible, unprecedented nationwide uprising against their company has scared them,” Marlow says. “But at the same time, they are just absolutely unwilling to make the actual changes they need to make in order to legitimately respond to these concerns. So this is the best that the company is willing to do.”

This summer has been a scorcher for much of the Northern Hemisphere. June and July marked the hottest two-month stretch in Europe since record-keeping began. The contiguous US endured its hottest month on record in July. South Korea saw its highest-ever recorded temperature.  

The heat isn’t over yet, but some scientists are already looking ahead to 2027. Experts say the latest El Niño event is going to affect next year’s temperatures more than this year’s.

So as the summer (slowly) starts to wane and temperatures (hopefully) start to come down, why has it been so hot this summer? What’s coming next year, and how should we prepare for it?

As we burn fossil fuels and fill up the atmosphere with greenhouse gases, temperatures all over the globe are on the rise—climate change makes heat waves more likely and more intense. But different regions see different warming rates, and Europe takes the prize for the world’s fastest-warming continent. (It’s second only to the Arctic in terms of regional warming.)

So it’s not terribly surprising that Europe has seen a particularly brutal summer, battered with heat wave after heat wave. One study looked at the continent’s May heat wave and found that climate change played a major role: A similar heat wave in 1976 would have been about 3.5 °C (6.3 °F) cooler than it was under today’s conditions.

The US hasn’t been excused from the heat either. July’s record for the contiguous US (which excludes Alaska and Hawaii) officially ends one held by July 1936 for nearly a century. It’s concerning that we’re breaking records set during the Dust Bowl, an environmental disaster across much of the country.

But looking ahead to next year, El Niño could have even more in store.

A quick crash course here: There’s a natural variation in patterns across the oceans and atmosphere called the El Niño–Southern Oscillation, or ENSO. Basically, over the course of several years, feedback systems between the ocean and wind patterns shift one way and then another. (These two states are the El Niño and La Niña events.)

The Pacific Ocean gets a lot of sunlight, warming up the water’s surface. In normal conditions the trade winds, caused by Earth’s rotation, carry that warm water west,  forcing colder water deep in the ocean up toward the surface in the east. In turn, warm air rises, flows east, and sinks again.

During an El Niño, the trade winds weaken and heat stored in the central Pacific builds up, warming up the air above it and creating a pocket of air that disrupts movement in the atmosphere and oceans, altering rainfall and weather across the globe.

We’ve already entered an El Niño phase, defined by the National Oceanic and Atmospheric Administration as a period when we see the temperature in a specific part of the Pacific Ocean get 0.5 °C hotter than usual, plus associated changes in the atmosphere.

And this could be a big deal for global temperatures. El Niño doesn’t actually add energy into the climate system or warm up the entire globe on a long-term scale. It’s essentially just taking heat that’s been stored in the oceans and releasing it into the atmosphere.  

But climate change has pushed a lot of heat into storage in the atmosphere and oceans—so combining the effects of this year-to-year variation with that long-term trend could have brutal results.

This El Niño is expected to be an especially notable one. Some forecasts predict that the event could peak at over 3.5 °C above the average, potentially making it the strongest on record. It also came on quite quickly, representing “one of the fastest onsets in the observational record,” writes climate scientist Zeke Hausfather in an analysis for Carbon Brief.

And while this El Niño is already starting to have an effect on temperatures, it’s still ramping up. El Niño’s effect on global temperatures tends to lag development of the ocean pattern by several months, and the effects will likely be more significant next year. 

In some recent El Niño periods, record-breaking temperatures came during the second calendar year of the event, Hausfather points out in his analysis. The most recent El Niño developed in 2023 and ran into 2024, and 2024 is the reigning hottest year on record. There’s some uncertainty in trying to predict how the rest of this El Niño will play out, but so far, it is set to be a doozy.

Given how brutal these summer heat waves have been, there’s a pretty high likelihood that much of the world could see even higher temperatures next year. “El Niño conditions will pour fuel on the fire of a warming world,” United Nations Secretary-General António Guterres said in a video statement in June.

It’s time to start preparing for it, and individuals can take some actions in the near term: If you’ve been putting it off, I’d buy that air conditioner, install solar and a backup battery, or upgrade the insulation in your home. 

In the longer term, though, temperatures will keep climbing because we’re still burning fossil fuels and driving climate change. As Guterres said in his statement, “The only effective response is climate action equal to the crisis: ending the addiction to fossil fuels, accelerating the shift to renewables, protecting the most vulnerable, and delivering early warning systems for all.”
