Desperate Idea to Rein In Melting "Doomsday Glacier"

Map of Antarctica. The Thwaites glacier is seen 
to the left. If it melts global sea levels
could rise dramatically. 

Climate scientists for quite awhile now have been watching with dread something they've dubbed the "Doomsday Glacier."  

Before you get too panicked,  the glacier won't end the world.  But at some point, it might cause enormous trouble that would be felt around the globe.  

The official name of this thing is Thwaites Glacier in Antarctica. It's about the size of Great Britain, and it is melting.

The "Doomsday" label is because the glacier is so huge and is melting so fast, that its effects are already being noticed. The thawing glacier already accounts for four percent of the world's annual sea level rise. 

Were the glacier to entirely collapse, it would raise global sea levels by about 65 centimeters or roughly two feet. Hence the "Doomsday" label as that much of a sea level rise would be truly catastrophic for coastal cities and communities worldwide.  

Each centimeter of sea level rise would expose an estimated six million people worldwide to coastal flooding, so imagine what 65 centimeters would do. 

Oh, and if the Thwaites Glacier collapses, it could destabilize the much bigger ice sheet behind it. If that big ice sheet goes, that could add another 10 to 15 feet of sea level rise. This wouldn't happen tomorrow, but it's a big enough threat to start thinking about, even if the catastrophe is decades or even a century into the future.

At this point, there's no way to stop Thwaites Glacier from continuing to melt. But maybe people can slow the melt down.  And maybe slowing the melt rate would buy time while us humans struggle to stop the flow of fossil fuel emissions into the atmosphere.  If fossil fuel emissions stop, so too, would climate, eventually at least.  

 ut we are nowhere near that moment yet.

One off the wall, expensive but still perhaps viable idea is to put a huge barrier around Thwaites glacier to stop warm water from getting at it. 

According to Interesting Engineering:

"The proposed structure would be just under 0.1 miles (152 meters) tall and stretch roughy 50 miles across key parts of the seabed in front of Thwaites Glacier. Anchored to the ocean floor, the curtain would act as a physical barrier, limiting the flow of warm seawater that melts the ice shelf from below,"

"The plan faces major technical challenges. The structure would need to survive extreme Antarctic conditions, deep water pressure, moving ice and long-term ocean exposure. Even supporters acknowledge it could take years before any full-scale deployment is possible."

It would also be incredibly expensive, to the tune of several billion dollars. It's unclear from where that money might come.  The logic behind spending that kind of money on a Thwaites Glacier barricade is that it would still be way less expensive than dealing with an eventual 10-foot sea level rise. 

At the very least, this whole thing is a potential research opportunity. 

Probably with this giant, expensive curtain in the back of their minds, scientists are drilling way down through the glacier and deploying instruments to see how warm water is interacting with the base of the glacier.

Data will be transmitted daily via satellite for at least a year. It'll be a way to figure out how deep ocean water in a warming climate affects glaciers it comes in contact with. 

"This is one of the most important and unstable glaciers on the planet and we are finally able to see what is happening where it matters most,'" said Pete Davis of the British Antarctic Survey. 

I have no idea whether this barricade will ever get built or whether the collapse of this "Doomsday Glacier is imminent. But it's just one trouble spot in a world of potential crisis points brought on by climate change.  

More Wintry Weather But Very Little New Snow Coming For Vermont

Henry The Weather Dog takes a quick measurement
of last night's very light snow in St Albans, Vermont
before rushing back into his warm house

 Yesterday's series of fronts left us with just the slightest amount of new snow. Which is fine, since I've really soured on the idea of shoveling heaps of it. 

Burlington has just 0.3 inches of snow. Here in St. Albans, it amounted to 0.8 inches, in other words just shy of an inch. 

I'm sure some of the ski resorts picked up one to three inches to freshen things up a bit  But we're not exactly going through a big cleanup like post-blizzard southern New England continues to deal with. 

Some of us might see a couple more snow showers this morning, but it any snowflakes appear in the sky, it won't amount to anything.

For some of of us, especially in the Champlain Valley the high temperature today hit just after midnight before cooler air began flowing in.  Temperatures today will stay just below freezing. An exception might be southern Vermont valleys, which could sneak up to 33 or 34 degrees.

We've got another cold one coming tonight, as that seems to be our style this winter. By dawn tomorrow, most of us will be in the single numbers above zero, but the cold spots will get below zero. Those readings will seem mild compared to what's coming by Monday. More on that in a bit.

On Friday, strong end of February sun will get us into the low and mid 30s, which is about normal for this time of year. 

ARCTIC COLD FRONT

It still appears we'll have an ever so brief, sort of hint of spring on Saturday, but it definitely won't be all chirping birds and blossoms.

As it warms up Saturday morning, a stiff south wind will kick up, especially in the Champlain Valley. Winds there will gust over 40 mph. Which means it won't exactly feel balmy out there. 

The cold front should arrive in the afternoon, so we might see temperatures already falling before sunset. 

We'll probably will see some snow showers, with maybe a little bit of rain Saturday before the cold front arrives. Again, anything that comes out of the sky Saturday won't amount to much. 

As the cold air blasts in Saturday night and Sunday, a disturbance scooting in from the west might drop a little snow on us. But those indecisive compute models disagree on whether that would happen and if it does, how much snow we'll get.

For now, anyway, it doesn't look like the snow will amount to much more than an inch, but we'll keep you posted. 

We're definitely sure we have a late season Arctic blast on our hands. It'll hit just as March arrives, so it won't have the intensity of cold snaps we saw in late January and early February. 

Still, it'll be a shiver me timbers couple of days. High temperatures both Sunday and Monday will be in the teens, which is a good 20 degrees below normal for this time of year. Lows Monday morning will be well below zero. Early guesses are in the single numbers below zero in the Champlain Valley and southern Vermont hot spots, and the teens below elsewhere. 

Tuesday morning lows might be below zero too.

There's a fairly decent chance that in the warmer spots in Vermont, like around Burlington, the chill early next week might well be the last subzero temperatures until next winter.

Beyond early next week, the forecast gets hazy. It will warm up at least a little, There might be some sort of small storm next Wednesday, but that still has a lot of question marks attached to it.

 The computer models are still insisting on a true thaw beginning roughly a week from now. .That thaw would last several days if these models are correct. But, you've heard me say before I don't trust these long range forecasts, and nothing is changing my mind here.

I continue to hope for that thaw, but know that by the time we get to a week from now, that thaw might well vanish in favor of more winter weather. 

However, since we're getting into March, it's going to be harder and harder for temperatures to stay below freezing all day. 

Hurricane Melissa Now Tied For Strongest Atlantic Hurricane On Record

Satellite view of Hurricane Melissa just before it hit
Jamaica in October. A National Hurricane Center 
review, issued today, indicates Melissa tied for 
the strongest hurricane on record in
the Atlantic basin. 

When we were reporting on Hurricane Melissa trashing Jamaica  back in October, we described it as one of the strongest Atlantic Ocean hurricanes on record. 

Since then, the National Hurricane Center has taken a deep dive into the mechanics and existence of that powerful hurricane. On Thursday, they announced their analysis shows Hurricane Melissa is actually tied with a 1980 hurricane as the strongest on record for the Atlantic.

Hurricane Melissa killed 95 people, including 45 Jamaicans and 43 Haitians.  

When the hurricane was raging, its highest winds were estimated at 185 mph, putting it in the top six list of strongest Atlantic hurricanes.

But a National Hurricane Center post-storm analysis, released Thursday, shows the hurricane actually had top sustained winds of 190 mph not long before landfall. Winds did "diminish" to 185 mph when it came ashore in Jamaica, but I'm sure nobody there noticed the difference the the screaming roar of the beastly storm. 

The only hurricane known to be as strong as Melissa in the Atlantic was Hurricane Allen in 1980. That storm reached its top strength in the the middle of the Gulf of Mexico. Allen caused 220 deaths in Haiti due mostly to flooding.  The hurricane weakened rapidly as it made landfall near Brownsville, Texas. 

As it hit the coastline of Jamaica, Hurricane Melissa's sustained winds of 185 put it in a three way tie for strongest winds in a hurricane at landfall. The others were Hurricane Dorian in the Bahamas in 2018 and a deadly hurricane in South Florida back in 1935.

Not surprisingly, the winds caused immense damage in the part of Jamaica hit by the strongest winds. According to the National Hurricane Center's report:

"Extreme winds destroyed virtually all wooden structures, stripped roofs from most building and even causes severe damage to concrete construction. Vegetation suffered extreme damage not only near the coast, but in mountainous areas across the entirety of western Jamaica as the eyewall passed over the island. Trees in that area were completely defoliated, and in several locations the force of the wind was sufficient to strip bark from trunks and scour paint from walls and buildings."

 Another measure of a hurricane's strength is how low the barometric pressure gets in the core of the storm. Melissa's air pressure in the eye got as low as 26.34 inches or 892 millibars. That ties with the 1935 hurricane as the lowest pressure in an Atlantic hurricane as it was making landfall. . 

The National Hurricane Center's final report also notes the incredible amount of lightning in Melissa's eyewall.  The eyes wall is the circle of intense winds and rain surrounding a hurricanes. The eye walls in most hurricanes usually have little or no lightning. Melissa had a ton of it, at one point showing 600 flashes per 30 minutes. 

Wind sensors in Jamaica were few and far between and most of those failed in Melissa's high winds. A school in Jamaica did record a gust to 131 mph. 

As is the case with most hurricanes, Melissa dumped incredible amounts of rain. Up to 35 inches fell in southern Haiti, 32 inches across the interior highlands of Jamaica and 27 inches in southwestern Dominican Republic. 

Melissa appears to be part of a disturbing trend in Atlanta Ocean hurricanes. The overall number of them doesn't seem to be increasing, but the number of Category 5 storms - the strongest of the bunch -seems to be increasing. 

In 2025, only five hurricanes formed in the Atlantic Ocean, but four of them were major, with sustained winds of at least 111 mph. Three of them were powerful Category 5 storms with sustained winds of at least 157 mph. 

Warm ocean water is jet fuel for hurricanes, and the water temperature where hurricanes usually develop has been getting hotter and hotter, thanks to climate change. If the conditions are right, these ultra-warm waters have an easier time developing extra strong hurricanes. 

One study found that climate change increased the strength of all 11 Atlantic hurricanes that formed in 2024.

It's really looking like a warming world will make hurricane season more terrifying that it has ever been before.  

Blizzard Update: More Snow, Power Outages Linger, Damage Assessments Begin

Satellite views of the Blizzard of '78 and the Blizzard of 
26 look eerily similar. The Blizzard of '78 was
more destructive because it brought storm surges
through four high tide cycles. This week's
blizzard caused coastal flooding through one
high tide. However, snowfall was greater this
time compared to 1978 

It was snowing again this morning in the areas hardest hit earlier this week in the Blizzard of 26. It's not much snow, but it's adding insult to injury as people continue to dig out. 

More than three feet of snow fell in some areas.

The death toll from the storm is still being assessed. Many winter storm deaths come in the days after the snow has stopped falling. 

That's when people have heart attacks shoveling snow, die from carbon monoxide as snow blocks vents and exhaust systems.  There's also car crashes on icy roads and accidents during storm clean ujp. 

So far, six deaths have been reported just on hard-hit Long Island, New York. Five people died on the island from heart attacks as they were shoving the deep snow

A sixth person was  found deceased beneath mounts of snow in Deer Park, Long Island. A worker hired to shovel snow at the complex for residents age 55 of over found the body. The cause of death has not been determined, but police said it's not suspicious. 

In Rhode Island,  a college student was found dead in a running car Monday evening. Snow blocked the tailpipe, which means carbon monoxide backed up into the car. Another person died when he was struck by a truck on the Mass Pike as he  were trying to remove snow from a vehicle.

AccuWeather is estimating $36 billion in damage and economic losses from the storm.That includes damage to homes and businesses, disruptions to commerce and supply chains, problems with shipping operations at majorhubs, financial losses from power outages, travel delays and damage to infrastructure. 

A neighborhood full of people try to dig their street
out of record deep snow in Providence, 
Rhode Island on Tuesday. 

AccuWeather did not tease out how much of the total was in damage and how much was economic losses due to power and transportation disruptions. 

As of noon today, more than 150,000 homes and businesses still had no power in Massachusetts, mostly on or near Cape Cod.  

Power was still out across most of Cape Cod on Tuesday. Six towns on the Cape had virtually no powFew gas stations were open, and those that did had long lines. Things had improved by this morning. Only Wellfleet was completely without power. Service was partly restored to the other towns. 

Utility officials said they hope to have electricity restored to almost everybody on Cape Cod by Friday night. 

Vermont  has sent help in the form of snow clearing equipment. Thirty-two VTrans employees left Vermont this morning to help clear snow in Massachusetts. Video showed a convoy of state dump trucks and bucket loaders an Interstate highway Tuesday morning bound for Massachusetts. 

 We can spare the equipment because only southern Vermont received snow from the blizzard and even that amounted to only a few inches. No large snowstorm are in the Vermont forecast. 

As the snow its cleared, damage to buildings is becoming apparent. 

A high school gym room in Kingston, Massachusetts collapsed under the weight of the snow.  A gas station canopy on Cape Cod was shredded by high winds and heavy snow.  Fallen trees are still blocking some roads in southeastern Massachusetts. 

In New Jersey, a church steeple was left leaning after the blizzard and will have to be torn down. 

Other cities are beginning to emerge as having set all time records for a single snowstorm. New Bedford, Massachusetts received 37 inches of snow, its biggest-ever snowstorm. We have a new front runner for city with the most snow. Fall River, Massachusetts reported a storm total of 41 inches. 

It's late in the winters, so you'd think a thaw would come along and just melt all this snow fairly quickly But nope! 

Temperatures in the blizzard zone will get above freezing this afternoon, tomorrow and Saturday, but not be overly wide margins. A late season Arctic blast will keep temperatures below freezing Sunday and early next week. 

Even worse, a little more snow is in the forecast. An inch or two of new snow fell from New York City to Cape Cod this morning. A little more snow might fall Thursday night and again Sunday. Luckily, these snowfall do not look very big. At least at this point. 

I'm sure a several million people that got hit by this blizzard are seriously pining for spring. 

Winter Just Doesn't Want To Quit In Vermont, Rest Of Northeast

Our house in St. Albans, Vermont is awash in snow, and 
the gardens out front won't be blooming anytime 
soon judging from this scene taken this morning. 

Unlike many recent winters, it's the end of February and we do not yet have any real signs of spring here in Vermont or the rest of the Northeast. 

Even when an extended forecast offers a hint of warm weather a week or two out, that always seems to be snatched away at the last minute and it stays cold. 

Here in Vermont it snowed again this morning. Not much, just enough to be annoying. We has 0.4 inches here in St. Albans as of 8 a.m.  

Temperatures across Vermont were mostly in the teens as of 8 a.m. but the warm front causing this morning's snow should blow through, bringing many valleys to readings a little above freezing this afternoon. 

That "warmth" won't last long.

A cold front is coming toward us late this afternoon. If this were summer, I'd be yelling about the risk of severe thunderstorms. But it's winter, so the cold front will crank out a bunch of snow showers and a few snow squalls here and there. Those would be the winter substitute for strong thunderstorms.

We won't get much snow this evening, with  most of us getting another inch or less. But the rapidly changing weather and falling temperatures around those expected snow squalls mean you might see some unpleasant, icy surprises on the roads on the way home late this afternoon and evening. 

THURSDAY/FRIDAY

The cold front is a little stronger than we thought it would be (of course!) so they've subtracted a few degrees from previous forecasts. It'll only get into the 20s to around 30 tomorrow and it''ll be back down in the single numbers tomorrow night. 

After a chilly start, Friday will be nice enough in the afternoon with sunshine and temperatures in the 30s, with some upper 20s in high elevations and some corners of the Northeast Kingdom.

By the way, the blizzard zone near New York and far southern New England are getting an unwanted burst of a couple inches of snow this morning. They also might get nicked by a weak storm Thursday night, and possibly another few inches of snow next Monday.

I'll have an update on the areas hit by the blizzard in a post later today.

ARCTIC FRONT

It still looks like we have one warmish day, or maybe part of a warmish part of a day when we get to Saturday. By then, another cold front will be approaching us. Ahead of that front, we'll get a brief squirt of mild air that might get us into the 40s.

However, some of the models are speeding up an approaching Arctic cold front, so I wonder whether it will stay mild all day in the north. It's possible the mild air could get pushed out before the day is over on Saturday. We shall see!

What's definite, though, is behind this front is really cold air. March will start with frigid January weather. Temperatures will be at least 20 degrees below normal. Highs Sunday and Monday will only be in the teens, with maybe a couple low 20s south. Overnight lows Monday and Tuesday nights will get below zero again, like we haven't had enough of that already. 

It'll warm back up a little toward the middle of next week. Long range forecasts are suggesting a bonafide thaw once we get a week into March. I'm not trusting that forecast yet, since so many hints of warmth in extended forecasts disappeared as forecasts were updated.

Meanwhile, enjoyVermont's forever winter.  

Are Pennsylvania Ice Jams A Glimpse Of Vermont's Early Spring Future?

An ice jam in Swanton, Vermont after a rainy, warm
January thaw in 2018. This will be the first early
spring in a few years in which ice jams are
a real concern However, there's no
evidence that there's anything imminent. 

 Rain and a spring thaw in parts of Pennsylvania last week caused several potential dangerous ice jams.

Luckily, the Pennsylvania jams either broke up fast enough to prevent serious damage or hit in rural areas where there was little to damage. But those jams last week prompted some flash floods warnings and evacuations. 

It was a reminder, though, that a winter with lots of cold and snow can really create trouble when the spring thaw arrives in earnest. 

The same thing could happen here in Vermont later this spring. 

After a bitterly cold late January and early February. the weather abruptly turned in western Pennsylvania last Thursday and Friday. Thunderstorms dumped bursts of heavy rain on that region last night. By noon Friday, Pittsburgh's temperature was up to 63 degrees. 

That kind of late winter weather is a recipe for ice jams. Thick ice on rivers broke up in that weather, and the chunks of ice got stuck on river beds, bridge abutments and other obstacles. 

 It has temporarily gotten colder in Pennsylvania, so the risk of ice jam floods has eased. But if there are still frozen waterways there or anywhere else, there's a risk of ice jam floods as we head toward spring.

"Anywhere else" includes here in Vermont.

Pennsylvania's experience makes me wonder what might happen in Vermont later this spring. Ice on the rivers is thicker than it's been in years. There's a fair amount of snow on the ground ready to melt.

No real thaws or heavy rain is in the forecast. But a little more snow is in the pipeline. Thankfully no big storms, though. The later we get into March without a thaw, the more likely the weather could change abruptly to something warm and rainy. Which would set us up for ice jams. 

As prepped as Vermont seems for ice jam floods, we have a more than decent chance of avoiding trouble. In Vermont's history, we've had winters that were much colder, much snowier and much icier than this one. After most of those winters, the spring melt was gradual enough to only give us the usual minor spring lowland flooding. 

I'm only bringing this up because this is the first winter we've had in awhile in which river ice has gotten thick enough to build strong ice jams if the weather is right for them. 

To avoid trouble, we'll want perfect sugaring weather. That means mild, thawing afternoon and chilly subfreezing nights with only light precipitation. Under those conditions, the snow and ice softens and  gradually melt. . 

If we have a sudden, rainy warmup later in March, and the ice jams do develop, we can still be just fine.

Much like in Pennsylvania, our ice chunks under this fast thaw scenario would get hung up on river bends and other obstacles. The ice jam would then create flooding just upstream fro where the stuck ice is.  

Where these ice jams set up would spell the difference between slight inconveniences and real trouble. The unlikely but worst case scenario would be an ice jam just downstream from Montpelier. That would back the water up into the downtown, like it did so devastatingly in 1992.

Since Montpelier is to some extent recovering from the even worse July, 2023 flood, we don't need that. 

Bottom line: Don't panic, since there's absolutely no reason to. Instead just be aware if we have a spell of warm, rainy weather coming up over the next month.  

Wild Weather Videos: Wildfires In Plains, Incredible Sierra Nevada Snows

A huge wildfire in Oklahoma earlier this month. It was
one of many extreme weather events so far this month. 

Before this week's big blizzard hit the Northeast, other dramatic weather hit the U.S. raged. We had Plains wildfires, and incredible snows in the Sierra Nevadas. 

Everybody has cameras these days, so we have video of all these goings on. We have some examples here. I'll have Blizzard of '26 videos in a separate post. 

Here's a video of a wildfire blowing into Woodword, Oklahoma on February 17. It gets pretty dramatic with fires whirls toward the end. As always click on this link to view, or if you see the image below, click on that

To say it snowed in California's Sierra Nevada mountains last week is definitely an understatement. To give us an idea of how it looks, Live Storms Media provided us with the scenery in Soda Springs, California. Looks like a good three feet of snow fell there within the first day and a half of the storm, as you can see in the video. I believe they eventually had about eight feet of snow. 

Click on this link to view, or if you see the image below, click on that. 

I have no idea why anyone would drive their Prius over California's infamous Donner Pass in a blizzard ,but here we are. Next video is people struggling in their vehicles amid heavy snow, shortly before authorities finally had the sense to shut down the heavily traveled highway. Click on this link to view, or if you see the image below, click on that. 

It isn't just the United States. Dramatic video shows an avalanche hitting a train in the Swiss Alps.  Nobody was injured in this one, and rescue services got everybody off the train within two hours. An avalanche his another train in Switzerland, derailing it and injuring five people. 

Here's the video of the train getting hit, along with some updates on other avalanches in the region. Click on this link to view, or if you see the image below, click on that. 

 Next, a cool aerial view of the ice in Pennsylvania's. Susquehanna River beginning to break up and jam in thawing weather recently. Rivers in the state had been heavily iced over by intense early February cold. The thawing lately has contributed to ice jams.
