I don't see the point in comparing photos of snow coverage in feb 2026 to the same area in march 2026. March is a spring month, of course snow coverage will be worse. Itd be more shocking if the snow coverage increased. they should show march 2026 vs. march 2025/2024/2023 etc.

Spring starts the last week of March. lazystar out there in floral print dresses on March first looking like an absolute tool. Enjoy your train set!

Shouldn't we be past being "stunned"? The past 11 years are the hottest 11 years on record. Climate catastrophe is coming, soon. Everybody knows this, even the vocal deniers (the ones with power, not the sheep they feed propaganda to). They've simply decided to profit off it instead of trying to slow it down. The "drill, baby, drill", "clean beautiful coal" lunacy and wanting to invade Greenland and Canada are all di…

Can’t remember the exact quote, but there is something in The Omen II about future wars being fought over food (Thorn corporation being involved in agriculture/fertiliser or something). Last time that I saw it I wondered if the Ukraine conflict might be about control of the “Breadbasket of Europe” as much as anything.

But of course Thomas Malthus was wrong about everything and we just keep need to growing populations.

Earlier quoted context omitted.

Where I'm at in the Sierra, March is typically very close to as snowy as Dec/Jan/Feb and the snowpack is still increasing, not decreasing. Late March is typically the peak depth. March avg snowfall is 62", this year we got 1", the driest March on record, on top of it being incredibly warm.

Conversly in east, wettest/snowiest jan-march on recent record. Today, april second, we got snow in coastal new hampshire. Which of course isn't an antithesis to the lack of snow in the west, and likely is literally the flip side of the "same problem". but interesting

11" of snow in the Sierra on April 1, as well!

March is a spring month at sea level.

Incredible observation. Seasons begin and end on different days depending on sea level. I was under the impression that the first two thirds of March was winter at every elevation in the northern hemisphere. singleshot_ has added much to this conversation.

Utah and Colorado had an awful winter, full stop.

California did quite well in December. Then late February and early March came along, and a rain event at high altitude melted a lot of the snowpack, followed by a not-uncommon heatwave in mid-late March melted a lot of what was left.

Our whole flood control and water supply system is designed around the expected storage of water as snow.

Ignoring horrifying drought scenarios, it is also troubling to think about how this will change if we start having warm winters and more of the winter precipitation as rain.

I think the worst case would be if we end up like some tropical countries, where they can have disastrous flooding and then drought in very short cycles. The water comes all at once and you cannot hope to control or contain it. But there are also gaps that strain the ability to store enough water and manage consumption rates.

I have to ask because this makes no sense to me: In the article, there is a picture of 3 workers taking a snow survey and finding "zero measurement of snow". This is reported as "the second lowest since 2015". How is any measurement of a quantity of an item less than zero? You can't have negative snow to my knowledge.

I just kind of assumed they meant no additional snow to add to the accumulated amount they have for the season compared to 2015.

April snowfall is also typical. With current forecasts, we will be far short of normal April snowfall as well.

There are quite a few comments here talking about how comparing images from feb/march isn’t useful. Here’s data on what’s going on. This snowtel location is within the Utah picture in the article. https://www.cbrfc.noaa.gov/dbdata/station/swegraph/swegraph_...

Where can I find similar data for the Columbia River basin? That's where we're going to see large impacts on hydropower production come mid-to-late summer, I suspect. Impacts for the PNW and CA.
