‘Weather Whiplash’ Could Be a Disturbing New Normal in a Weird, Warming World
After praying for rain for weeks, the US state that saw some of the year’s biggest wildfires in 2022 found itself soon suffering a deadly deluge.
This story is part of CNET Zero, a series that chronicles the impact of climate change and explores what’s being done about the problem.
I’ve lived in the high desert of the southwestern US most of my life, primarily in New Mexico and Colorado. In those four decades, I’ve never seen it as dry here as in 2022. In all that time, I’ve also never seen it as wet as this year.
In northern New Mexico, the year began with months of unseasonal heat, dryness and extreme wind that fueled the largest wildfire of the year in the lower 48 states. It burned through 340,000 acres of the Sangre de Cristo mountains and destroyed or damaged over a thousand homes and other structures.
Then, in the middle of June, the annual monsoon rains thankfully arrived to douse the fires. But they stayed a couple months longer and dumped nearly twice as much moisture as the previous year (or the year before that). In fact, we were still seeing some monsoon pattern precipitation several weeks later than normal.
There’s a term for this remarkably rapid turnaround in weather patterns that an increasing number of scientists have begun to use, both in the mainstream media and academic publications: weather whiplash.
«The huge shift in weather you experienced in New Mexico this summer is a perfect example,» Jennifer Francis, acting deputy director at the Woodwell Climate Research Center in Massachusetts tells me.
Francis is lead author on a paper published in September in the Journal of Geophysical Research: Atmospheres on measuring weather whiplash events, which can be loosely defined as abrupt swings in weather conditions from one extreme to another.
At my home in the high desert this year, those swings translated into a Spring filled with smoke, heat, wind and the first emergency alert system notice I’d ever received warning me to get off the road immediately due to an approaching dust storm. By July the scene changed to one filled with rain, mud and more alerts, this time warning of flash flooding.
«Weather patterns are getting «stuck» in place more often, causing persistent heatwaves, drought, stormy periods, and even cold spells to happen more often,» Francis explained via email.
Her work shows all this stalled weather is connected to the rapid warming of the Arctic, which impacts the jet stream and in turn affects weather further south.
«These stuck weather patterns sometimes come to an abrupt end by changing abruptly to a very different pattern. This is weather whiplash.»
The phrase has been increasingly used in climate science circles for the past several years, but Francis points to a number of other instances of the phenomenon on full, sobering display in 2022 alone.
A July heatwave immediately followed exceptionally wet, cool weather in the Pacific Northwest and Northern Rockies in June. This turnaround was most dramatic in the Yellowstone region, where historic flooding in the first month of summer took many by surprise and claimed hundreds of homes but, somewhat miraculously, no lives. Shortly afterwards, temperatures soared several degrees above average and the region dried out.
Earlier in the year the inverse played out in Texas, where a spell of 67 consecutive dry, hot winter days in Dallas were followed by the city’s heaviest rains in 100 years, leading to flash flooding and a declaration of disaster by the state’s Governor.
Seasonal See-Saw
From late March until early June, much of northern New Mexico saw no measurable precipitation for a stretch of more than 70 days. Even for the current era, which many scientists suspect is the beginning of a megadrought in the southwestern US, that’s unusually dry.
This dryness, along with unseasonable heat and often extreme winds whipped up the embers of two controlled burns in the Santa Fe National Forest that had been secretly smoldering for months. Two wildfires sprang to life, eventually combining to form the 340,000-acre Calf Canyon-Hermit’s Peak fire complex.
The inferno burned homes, ranches, businesses and livestock, but didn’t claim any human lives – at least, not directly. Tens of thousands were evacuated from nearby cities and villages for weeks as fire devoured some of the state’s most rugged and beautiful terrain over the course of more than two months.
I visited some of the impacted communities to witness the total disruption and devastation while waiting to see if the flames would continue to push closer to my own community near Taos, less than 20 miles from the northwest edge of the fire.
For weeks it looked as though a nuclear bomb had been detonated just over the ridge of mountains near my home. A pyrocumulus mushroom cloud of smoke from the fire reached up into the atmosphere, a constant reminder of impending doom one valley over.
Sometimes the wind would shift and blow all that smoke our direction. It was possible to see this coming almost an hour in advance as a brown stream of smog would suddenly obscure the mountains. As it finally reached us, our eyes would water, our lungs would begin to burn and everything we wore or carried would take on the aroma of a barbecue. Minutes later, the sun would be blotted out on an otherwise sunny day. They were all sunny days back then.
My family would retreat inside every time the smoke came, of course. Then, in early June, another fire ignited on the opposite side of our community from where the megablaze was burning. We found ourselves surrounded. No matter which way the wind blew, there was a good chance it would blow smoke in our faces.
At this point our daughter was quarantined at home with COVID. We faced the very apocalyptic choice of keeping the windows open for better anti-viral ventilation or closing them to keep the smoke out. It wasn’t a particularly hard choice. We closed the windows. Inhaling smoke certainly isn’t great for getting over COVID, after all.
Then, in mid-June, both the weather and its impact took dramatic turns. The annual monsoon rains arrived right on time, and with an unusual intensity. Ironically, this is how New Mexico’s largest ever wildfire ended up claiming human lives after the flames had stopped spreading.
The burn scars left by wildfires absorb less moisture than healthy landscapes with plenty of vegetation, and that led to flash flooding. June and July in northern New Mexico saw repeated cycles of heavy rains, including a particularly heavy storm on July 21 that deluged the Calf Canyon-Hermit’s Peak burn scar. A flash flood tore through the Tecolote Canyon subdivision outside the city of Las Vegas, New Mexico, sweeping tons of mud, rocks, burned trees and even vehicles down the creek drainage. Tragically, three people were caught in the flood and died.
In the span of weeks, citizens in New Mexico went from fleeing fires to fleeing floods. Whiplash might describe the disjointed nature of this past summer, but it doesn’t begin to capture the anxiety brought on by this new realization that life in the 21st century might be about being ready for absolutely anything.
In June I was hauling water to my off-grid home in the back of a truck, 200 gallons at a time, and praying for the monsoon to arrive. The following month I was digging trenches to divert as much water as possible out of my driveway to lessen the persistent rain’s irritating habit of turning it into a muddy quagmire. This is to say nothing of the background anxiety created by nearby fires, floods and at least one epic wind event that took the roof off a neighbor’s house.
The Climate Connection
At least one group of researchers predicted this before it happened. Well, sort of.
On April 1, just five days before that massive fire in New Mexico sprang to life, a paper was published in the journal Science Advances titled «Climate change increases risk of extreme rainfall following wildfire in the western United States.»
The paper describes how scientists used climate models to predict that if global warming continues unabated, the western US will begin to see many more instances of extreme wildfires followed by extreme rainfall. They didn’t wait decades to see their predictions come true. It happened just weeks later.
«I would qualify what happened in New Mexico as extreme precipitation following extreme wildfires,» UCLA and National Center for Atmospheric Research climate scientist Daniel Swain, one of the authors of the study, told me. «Some of those fires were literally still burning pretty vigorously when the rain started. You really can’t get any whiplashier than that.»
Swain is one of a number of climate scientists digging into the data to determine what is creating this new, very 21st century sort of see-saw. One of the main factors, he says, is that the warming of the planet is accelerating the water, or hydrologic, cycle that moves moisture from surface water to the atmosphere and back again via precipitation.
«You actually get an exponential increase in the water-vapor-holding capacity of the atmosphere,» he explains.
Basically, for every degree centigrade of warming, the atmosphere can hold 7% more moisture. These increases compound over time, sort of like interest in a bank account, which provides the exponential acceleration of extreme rainfall events that are more frequent and more intense.
Swain describes our atmosphere as a sponge that grows ever larger as it warms, periodically soaking up potentially larger amounts of moisture and then dumping it all at once on some unfortunate locale. But this expanding sponge is also exacerbating dryness in places where it extracts an increasing amount of water out of the landscape.
This means drier dry periods and wetter precipitation events, sometimes back-to-back. Whiplash.
Swain cautions that it’s too soon to know how much of the weather whiplash experienced in northern New Mexico this year can truly be blamed on climate change versus just basic bad luck and the natural variation and randomness that we’d see in our weather patterns even without global warming.
Climate scientists have developed so-called «weather attribution» models that quantify the effects of climate change directly on specific weather events like what was experienced this year in New Mexico, but the process can take several months or longer.
Weirder than Warming
When I first started covering climate two decades ago, a climatologist told me the phrase «global warming» wouldn’t fully describe what was going to happen to our environment and that it would be more like «global weirding.»
That phrase never caught on, but I’m starting to think weather whiplash might be its appropriate successor.
For decades now, talk about the warming climate has focused on increasing temperatures, but usually these are increasing average temperatures. However, we don’t experience climate in the aggregate. We live it day-to-day as weather that is increasingly extreme.
«If you get 20 inches of rainfall distributed as half an inch a day for 40 days it’s a very different picture than getting 20 inches of rainfall because it rains 10 inches one day and 10 inches the next,» Swain suggests. «The average might be the same, but you’re living in a completely different world.»
In other words, our experience of climate change can’t be fully captured by talking about how much temperatures or sea levels or rainfall are rising. It’s the extremes and the weirdness and the chaotic swings from one state to another that tell the real story and inflict the most trauma.
At the point this summer when wildfires were burning on both sides of our community I had a weird flashback to my childhood. One of my favorite things to read as a kid in the previous century was Choose Your Own Adventure books. They had this intoxicating ability to provide both an escape and agency at the same time.
It feels like we could use a little more of both things right now. Life today has the feel of all the potential adventures in those books happening back-to-back and often simultaneously. The only choice is to be ready for anything.

Get Ready for a Striking Aurora That Could Also Disrupt Radio Communications
Don’t expect the storm to cause a lingering problem, though.
A geomagnetic storm is threatening radio communications Monday night, but that doesn’t mean you should be concerned. In fact, it may be an opportunity to see a colorful aurora in the night sky.
The National Oceanic and Atmospheric Administration has issued a geomagnetic storm watch after witnessing a coronal mass ejection from the sun on Saturday. The watch, which was issued over the weekend and will expire after Monday, said the onset of the storm passing over Earth on Sunday night represented a «moderate» threat to communications. As the storm continues to pass through, it could deliver a «strong» threat on Monday night that could cause radio communications to be temporarily disrupted during the worst of it.
Even so, NOAA said, «the general public should not be concerned.»
A coronal mass ejection occurs when magnetic field and plasma mass are violently expelled from the sun’s corona, or the outermost portion of the sun’s atmosphere. In the vast majority of cases, the ejection occurs with no real threat to Earth. However, in the event the ejection happens in the planet’s direction, a geomagnetic storm occurs, and the Earth’s magnetic field is temporarily affected.
In most cases, geomagnetic storms cause little to no disruption on Earth, with radio communications and satellites affected most often. In extreme cases, a geomagnetic storm can cause significant and potentially life-threatening power outages — a prospect that, luckily, the planet hasn’t faced.
Switching poles
Every 11 years, the sun’s magnetic poles switch, with the north pole and south pole swapping positions. During those cycles, the sun’s activity ramps up as it gets closer to pole-switching time. The height of its activity is called solar maximum, and scientists believe we either may be entering the solar maximum or may be already in it.
During periods of heightened solar activity, sunspots increase on the sun and there’s an increase in coronal mass ejections, among other phenomena. According to NOAA, solar maximum could extend into October of this year before the sun’s activity calms and it works towards its less-active phase, solar minimum.
Even when geomagnetic storms hit Earth and disrupt communications, the effects are usually short-lived. Those most affected, including power grid operators and pilots and air traffic controllers communicating over long distances, have fail-safe technologies and backup communications to ensure operational continuity.
But geomagnetic storms aren’t only about radios. In most cases, they also present unique opportunities to see auroras in the night sky. When the storms hit, the plasma they carry creates a jaw-dropping aurora, illuminating the night sky with brilliant colors. Those auroras can be especially pronounced during the most intense phases of the storm, making for nice stargazing.
If you’re interested in seeing the aurora, you’ll need to be ready. The NOAA said the «brunt of the storm has passed» and even if it lingers into Tuesday, there won’t be much to see after Monday night.

Last Total Solar Eclipse for 20 Years Is Coming: How to See and Photograph It
It’s your last chance until 2044.
Get your eclipse glasses ready, Skygazers: the Great American Eclipse is on its way. On April 8, there’ll be a total eclipse over North America, the last one until 2044.
A total solar eclipse happens when the moon passes between the Earth and the sun, blocking the sun and turning an otherwise sunny day to darkness for a short period of time. Depending on the angle at which you’re viewing the eclipse, you may see the sun completely shrouded by the moon (called totality) or some variation of it. The more off-angle you are and the further you are from the path of the eclipse, the less likely you’ll be to see the totality.
The 2024 total solar eclipse will happen on Monday, April 8. The Great American Eclipse will reach the Mexican Pacific coast at 11:07 a.m. PT (2:07 p.m. ET), and then traverse the US in a northeasterly direction from Texas to Maine, and on into easternmost Canada. If you want a good look at it, but don’t live in the path of totality, you shouldn’t wait much longer to book accommodation and travel to a spot on the path.
Or how about booking a seat in the sky? Delta Airlines made headlines for offering a flight that allows you to see the entire path of totality. Its first eclipse flight, from Austin, Texas, to Detroit sold out quickly. But as of Monday, Delta has added a second flight from Dallas to Detroit, which also covers the path of totality. The airline also has five flights that will offer prime eclipse viewing.
Not everyone can get on one of those elusive eclipse-viewing flights. Here’s a look at other options to nab a chance to see this rare sight and what to know about it.
Total solar eclipse path
The eclipse will cross over the Pacific coast of Mexico and head northeast over mainland Mexico. The eclipse will then make its way over San Antonio at approximately 2:30 p.m. ET on April 8 and move through Texas, over the southeastern part of Oklahoma and northern Arkansas by 2:50 p.m. ET.
By 3 p.m. ET, the eclipse will be over southern Illinois, and just 5 minutes later, will be traveling over Indianapolis. Folks in northwestern Ohio will be treated to the eclipse by 3:15 p.m. ET, and it will then travel over Lake Erie and Buffalo, New York, by 3:20 p.m. ET. Over the next 10 minutes, the eclipse will be seen over northern New York state, then over Vermont. By 3:35 p.m. ET, the eclipse will work its way into Canada and off the Eastern coast of North America.
Best places to watch the Great American Eclipse
When evaluating the best places to watch this year’s total eclipse, you’ll first want to determine where you’ll have the best angle to see the totality. The farther off-angle you are — in other words, the farther north or south of the eclipse’s path — the less of an impact you can expect.
Therefore, if you want to have the best chance of experiencing the eclipse, you’ll want to be in its path. As of this writing, most of the cities in the eclipse’s path have some hotel availability, but recent reports have suggested that rooms are booking up. And as more rooms are booked, prices are going up.
So if you want to be in the eclipse’s path, and need a hotel to do it, move fast. And Delta’s eclipse-viewing flight from Dallas to Detroit has just four seats left at the time of publication.
Eclipse eye safety and photography
As with any solar eclipse, it’s critical you keep eye safety in mind.
During the eclipse, and especially during the periods before and after totality, don’t look directly at the sun without special eye protection. Also, be sure not to look at the sun through a camera (including the camera on your phone), binoculars, a telescope or any other viewing device. This could cause serious eye injury. Sunglasses aren’t enough to protect your eyes from damage.
If you want to view the eclipse, you’ll instead need solar viewing glasses that comply with the ISO 12312-2 safety standard. Anything that doesn’t meet that standard or greater won’t be dark enough to protect your eyes. Want to get them for free? If you’ve got a Warby Parker eyeglasses store nearby, the company is giving away free, ISO-certified solar eclipse glasses at all of its stores from April 1 until the eclipse, while supplies last.
If you don’t have eclipse viewing glasses handy, you can instead use indirect methods for viewing the eclipse, like a pinhole projector.

In the event you want to take pictures of the eclipse, attach a certified solar filter to your camera. Doing so will protect your eyes and allow you to take photos while you view the eclipse through your lens.
There’s also a new app to help you both protect your eyes and take better photos of the eclipse on your phone. Solar Snap, designed by a former Hubble Space Telescope astronomer, comes with a Solar Snap camera filter that attaches to the back of an iPhone or Android phone, along with solar eclipse glasses for protecting your eyesight during the event. After you attach the filter to your phone, you can use the free Solar Snap Eclipse app to zoom in on the eclipse, adjust exposure and other camera settings, and ultimately take better shots of the eclipse.
2024 eclipse compared to 2017
The last total solar eclipse occurred in 2017, and many Americans had a great view. Although there are plenty of similarities between the 2017 total solar eclipse and the one coming April 8, there are a handful of differences. Mainly, the 2024 eclipse is going to cover more land and last longer.
The 2017 eclipse started over the northwest US and moved southeast. Additionally, that eclipse’s path was up to 71 miles wide, compared with a maximum width of 122 miles for this year’s eclipse. Perhaps most importantly, the moon completely covered the sun for just 2 minutes, 40 seconds in 2017. This year, maximum totality will last for nearly four-and-a-half minutes.
