Indianapolis has all-new streetlights. We need a new color.
Every Indianapolis driver is on edge driving in early spring. You never know when a chuckhole is lurking in the dark. Luckily, my drive is lit by cobra lights from start to finish. I trucked along in confidence, scanning my field of view, until not eighty yards away from my destination – 'CA-CHUNK!...CA-CHUNK!'
I heard the awful rimshot of my car entering and exiting a pothole on my front left, and then the inevitable repeat as the back left followed it in and out. The streets were lit, and I was vigilant. How had I missed it?
One of the best initiatives of Mayor Joe Hogsett's administration has been Operation Night Light. This much-needed initiative ended a 35-year moratorium on new streetlights in Indianapolis. In doing so, it not only added around 4,000 new streetlights to sidewalks and roads that had been pitch-black at night, but also swapped out the old bulbs for brighter, more energy-efficient LED bulbs.
Opinion: The most incredible city feature you might not notice
Better lighting at night is well-understood to improve public safety. That is, if it's implemented correctly.
The reason I'd hit that pothole had actually been because the light was too bright. The undirected, harsh white flooded my field of vision, creating a glare that blinded me and hid obstacles in newly formed shadows.
This is actually a common problem – extreme glare can hide the crime it was supposed to prevent. The bright-white LEDs create more glare and actually cause more accidents than warmer, dimmer, yellower colors. Of course, lower lights at night also help with sleep and mental health.
But it's not just us that I'm concerned about. It's bird migration season, and twice a year, over 40 million birds fly through, and over, Indianapolis in search of sprouting plants, hatching insects and lengthening sunlight. These include fragile species protected by the Migratory Birds Act and the Endangered Species Act.
However, while visiting our city, millions of them will die, distracted by harsh lights at night and confused by all-glass skyscrapers downtown. One thousand birds were killed in a single night by a single building in Chicago. The images of the carnage are unsettling, and the downstream ecological impacts are enormous.
Migrating insects are affected by this light too. They hatch before the last frost, or migrate in the wrong direction or incinerate themselves. The global insect population is nosediving just as we're beginning to understand they are essential to our survival. Insects are the base consumers that feed the animals we eat, and they are the most efficient way to pollinate our fruits, vegetables and grains. We starve without them.
Now, to be clear: I love Operation Night Light. I'd just suggest a small tweak to its implementation that would save the lives of millions of birds and insects, while also protecting people's lives and property better.
Change the color of the lights.
Warmer colors attract fewer insects and birds than cooler colors, like bright white, while also casting less harmful glare for humans. Anyone who has stared at pure white headlights and wondered if the brights were on knows this.
There are other ways to help these creatures, including lighting shields that direct light downwards, and UV coatings on windows that birds can see but are invisible to humans, preventing the all-glass bird murderers downtown from being so lethal. But those cost money, while changing the color of an LED bulb is typically a flick of a switch.
Ensuring consistent light colors seems like a win-win for all of us. Sometimes the small changes make the biggest difference.

How strong will that Gulf hurricane get? Hidden hot water, river flow may be key
Hurricane forecasting has improved dramatically over recent decades, but there's one major phenomenon that can still throw a wrench into even the most accurate forecasts — rapid intensification. That's what scientists call it when a tropical storm or hurricane's sustained wind speed increases at least 35 mph within 24 hours, and it happens for nearly all Category 4 and 5 storms. Researchers have some idea of the ingredients necessary for a storm to quickly strengthen like that, but it's a less precise guess than many other elements of hurricane forecasting. However, new research from the University of South Florida continues to chip away at the mysteries surrounding rapid intensification, especially in the Gulf of Mexico, by helping identify previously hidden pockets of hot water that could help feed storms. One study, published in February in the journal Environmental Research Letters, found that a plume of hot freshwater, floating on top of the denser, slightly cooler saltwater in the Gulf, could have been key to Hurricane Idalia's rapid strengthening in 2023. Researchers found that shortly before Hurricane Idalia jumped from a Category 1 hurricane to Category 4, it passed over this hot puddle of freshwater, and they determined that this provided the burgeoning hurricane a speed boost. Chuanmin Hu, a professor of oceanography at the USF College of Marine Science and an author of the study, said the discovery was a coincidence, a matter of the right devices at the right place at the right time. They initially set out to study this plume of freshwater, an annual occurrence in the Gulf fed from various freshwater rivers, including the Mississippi, over red tide concerns. But the team's slow-moving research gliders turned out to be perfectly placed to catch the incoming hurricane. And they showed, Hu said, that the deep layer of warm freshwater served as a power source for Idalia. This freshwater plume is a normal thing to see in the Gulf, but the research suggests that in 2023, it was deeper and larger than anything in recent history, potentially because of an intense amount of rain that fell on the Southwest in the months previous. 'Even right now, there's a plume following almost the same path, but the extent is much smaller and the duration may be shorter,' Hu said. 'This extensive long lasting plume [in 2023] was a record in the past 20 years.' READ MORE: What happens when hurricanes rapidly intensify? Researchers can easily track the outlines of the annual plume via satellite, but without the gliders, which can sample up to 200 meters below the surface, it's hard to know how deep the plume is. The gliders are funded by the National Oceanic and Atmospheric Administration, and Hu suggested that their continued use could provide forecasters another tool for predicting rapid intensification. 'These are really, really important measurements that help hurricane studies, and I hope they will continue in the future,' Hu said. Another USF-led study examining the same region of the Gulf also found a connection between unique ocean circulation and rapid intensification. The paper, published in December in the journal Geophysical Research Letters, suggests that in 2022, when Hurricane Ian powered up over waters near the Florida coast, it found waters warmer than usual — both at the sea surface and deeper below. Yonggang Liu, an associate professor at the University of South Florida and lead author of the study, said that water was hotter than usual because the region hadn't experienced a 'flushing' current like it normally does, so the waters were hotter and more stagnant than usual. Liu said his team analyzed 27 years of water temperature history from a series of buoys placed in the region and found that the deeper waters were warmer than normal when Ian plowed through. Usually, the sea surface is warmest and waters get cooler the deeper you go. That means that when Hurricane Ian moved over the Gulf, it churned up ever hotter water, fueling the storm even further, potentially giving it the boost it needed to jump from Category 3 to Category 5 as it closed in on Florida. 'The important part of those subsurface water temperatures is you can't detect it from satellites,' Liu said. 'That should be improved. The buoys are essential in this case.' Liu's team made a publicly available dashboard to display the data from those buoys. This month, it shows good news, he said. Deeper waters are running only slightly above average, a much lower figure than researchers saw with Hurricane Ian. That could be because this year, unlike in 2022, the Gulf Loop Current grew wide enough to hit a 'pressure point' that Liu's team pinpointed on the west Florida shelf. When the current grows broad enough to hit that spot, the paper found, it flushes cooler water up and down the west coast of Florida, cutting off a potential food source for would-be storms. 'The entire shelf will be replaced with cooler water from offshore origins,' Liu said. 'That kind of circulation was not seen during the last four years in the summer, only briefly, not persistently. This year is different.' Liu believes that expanding the buoy network up and down the coast of Florida, or even in geographically similar areas like North Carolina's coast, could provide a helpful tool for forecasters trying to find previously hidden pockets of hot water that could fuel storms passing through the area. 'More observations and monitoring of the subsurface is critical,' he said.

5 things to know for July 15: Flash flooding, HHS firings, Education lawsuit, Childhood vaccinations, Tariffs
5 Things Storms Vaccines Trump legal casesFacebookTweetLink Follow As Russian forces rained drones and missiles down on Kyiv last week, Ukrainian authorities urged residents to hide in bomb shelters and basements for safety. But one group was undeterred by the danger. A seriously ill child was in desperate need of a new heart, and when one became available, a doctor and his staff made the treacherous 10-mile journey across the capital city to deliver their precious cargo. Here's what else you need to know to get up to speed and on with your day. Millions in the Northeast and Mid-Atlantic region remain under flash-flood warnings this morning. According to the National Weather Service, slow-moving summer storms have already caused flooding in New Jersey, New York, Virginia, and Maryland, with more rain expected today. New York City experienced its second-wettest hour on record after a little over 2 inches of rain fell between 7 p.m. and 8 p.m. on Monday. A deluge of water filled at least one Manhattan subway station and several trains had to be suspended, delayed or rerouted. Impacts to air travel were reported at Boston, New York City and Washington, DC, airports. First responders in Pennsylvania conducted at least 16 water rescues and there were reports of more than 5 feet of water in some homes when over 7 inches of rain fell in less than five hours, authorities said. Water rescues also took place in Virginia after 2 to 3 inches of rain fell in less than two hours. 'You are hereby notified that you are officially separated from HHS at the close of business on July 14, 2025. Thank you for your service to the American people.' That was the message thousands of federal employees at US health agencies received when they were laid off by email on Monday. Although the job cuts were originally announced on April 1, they were delayed due to a legal battle. However, on July 8, the Supreme Court ruled that the Department of Health and Human Services may move forward with the terminations. The massive reduction in force stems from an executive order President Donald Trump issued in February. A lawsuit filed in federal court on Monday is the latest clash between more than 20 Democratic-led states and the federal government. This case involves the Trump administration's decision to pause or claw back critical funds for educational services. The states are asking the court to lift the administration's freeze on nearly $7 billion that Congress allocated for initiatives including after-school and summer programs, supporting the hiring and retention of teachers in low-income areas and helping immigrant students attain English proficiency. The Department of Education has withheld disbursement of the funding pending a review of how consistent these programs are with Trump's priorities. An estimated 14.3 million children remain completely unvaccinated, a new report issued by the World Health Organization and the UN Children's Fund said. Although that figure is down by 171,000 since 2023, too many children remain at risk for vaccine-preventable diseases. An additional 5.7 million children have only partial protection because they may not have received all the recommended doses of certain vaccine series. Public health experts say children living in conflict zones and low-or middle-income countries were particularly vulnerable. In high-income countries, vaccine hesitancy and distrust in institutions have led to a resurgence of vaccine-preventable diseases, including measles and polio. With President Trump threatening to increase tariffs on two of America's largest trading partners, consumers should prepare to pay more for certain products. Over the weekend, Trump called for 30% levies on the European Union and Mexico starting on August 1 — unless they make trade deals with the US. Although some businesses may absorb the tax themselves, others will have to pass it on to American consumers. Here are some of the items that could be affected: -Alcohol -Fresh fruits and vegetables, especially tomatoes and avocados -Medical equipment and surgical supplies -Electronics, such as computers, electrical equipment and audio and video equipment GET '5 THINGS' IN YOUR INBOX If your day doesn't start until you're up to speed on the latest headlines, then let us introduce you to your new favorite morning fix.

Extreme rainfall in Chicago underscores rising climate disaster costs
This week's sudden outburst of rain in Chicago has some sounding the alarm on climate-related weather disasters and the resources needed to mitigate them. The latest: More severe storms hit the Chicago area last night, with reported flooding in parts of the city and suburbs. The big picture: Tuesday's fast-moving storm dropped about 5 inches of rain in just 90 minutes on the near West Side, flooding viaducts and basements. That's more rain than what is usually the average for the entire month of July. Why it matters: This sudden burst was similar to storms that caused flooding in Texas and New Mexico, offering a sobering reality: Climate disasters are now a regular occurrence in Chicago. Reality check: It was just two years ago that a similar storm system whalloped the same West Side community, flooding basements and prompting the Biden administration to offer resources for cleanup assistance. Both Illinois U.S. Senators secured over $800 million in federal funds to help unmet needs for past state climate disasters in 2023 and 2024. Yes, but: That was before President Trump took office, and his administration wants to shrink the Federal Emergency Management Agency, which is used to help states with disaster recovery. Between the lines: Trump was quick to swoop in to help with the floods in Texas, but the backlog of other states' federal disaster requests is staggering. In May alone, the national average for outstanding requests was 13, while the normal average is just under four. For example, it took almost two months for the federal government to provide aid for cleanup after the massive tornado outbreak in St. Louis. The intrigue: Some Democratic governors are accusing the Trump administration of playing politics, responding faster to Republican-led states. What they're saying:"If you want to make a major change in the way that we as a nation do disaster recovery, that should be a process where people can anticipate what is going to change and what they can rely on right now," Carnegie Endowment for International Peace senior fellow Sarah Labowitz tells Axios. "With disaster relief, you need predictability," Labowitz, who publishes the Disaster Dollar Database, says. By the numbers: Extreme weather events cost the U.S. economy an estimated $180 to $496 billion per year in 2023 dollars, according to a 2024 report from the Senate Joint Economic Committee. The analysis found that the U.S. needed to invest between $69 billion and $345 billion to upgrade infrastructure to protect against just flooding. In Illinois, the average cost of federal assistance for climate disasters in 2024 totaled just under $55 million per disaster. If the state had to shoulder the cleanup burden alone, it would take just over 30 days to deplete the funds available, according to Labowitz. Zoom in: Mayor Brandon Johnson's administration has announced climate plans to improve stormwater infrastructure, but these recent storms may force the city and the state to think bigger about investing in mitigation efforts.
