From Watts Up With That?<\/a><\/p>\n\n\n\n

From Anthony Watts<\/a><\/p>\n\n\n\n

Dec 24 to Jan 25 was the 2nd biggest month-to-month temperature drop in the surface temperature record at 7.13\u00b0F in one month. <\/em><\/p>\n\n\n\n

As many readers know, we follow the U.S. Climate Reference Network (USCRN) closely here, keeping it updated monthly on the right sidebar along with the UAH global satellite record. I choose these metrics because I and others have shown the rest of the surface temperature record to be nothing more than a collection of warm-biased and unreliable statistically maladjusted garbage data<\/a>. Be as upset as you wish, but that\u2019s the facts, jack.<\/p>\n\n\n\n

This fact is something you won\u2019t see splashed across the headlines of the mainstream climate press: the U.S. Climate Reference Network (USCRN) just recorded its second largest month-to-month temperature drop in the entire time series, beaten only by the plunge from November to December 2009. That\u2019s right\u2014despite the endless drumbeat of \u201chottest ever\u201d claims, the pristine, state-of-the-art USCRN network is telling a different story for February 2025.<\/p>\n\n\n\n

Let\u2019s set the stage. The USCRN<\/a>, operational since 2005, is NOAA\u2019s gold standard for tracking temperature trends across the contiguous U.S. With 114 stations deliberately sited away from urban heat islands and other human influences, it\u2019s about as clean a dataset as you\u2019ll find. No adjustments, no homogenization\u2014just raw, reliable numbers. According to the latest NCEI report, January 2025 clocked in at a chilly 29.2\u00b0F for the contiguous U.S., already 0.9\u00b0F below the long-term average and the coldest January in the USCRN\u2019s 20-year record. Not exactly the \u201cscorching\u201d narrative we\u2019ve been sold.<\/p>\n\n\n\n

Fast forward to February 2025, and preliminary data (as of February 20) shows a jaw-dropping slide. While the full month\u2019s numbers are still trickling in, the month-to-month drop from January\u2019s 29.2\u00b0F is shaping up to be a whopper\u2014second only to the 2009 late-year nosedive. Back then, temperatures crashed by nearly 8\u00b0F between November and December, a seasonal anomaly that raised eyebrows but didn\u2019t fit the warming script, so it quietly faded from the spotlight. This time, early indications suggest a plunge approaching 7\u00b0F or more, a rare event in a dataset designed for stability and precision.

What\u2019s driving this? February\u2019s outlook from NOAA hinted at a cold snap across the northern tier, with La Ni\u00f1a\u2019s influence possibly flexing its muscle after a tepid start. But let\u2019s not kid ourselves\u2014attributing this to any single cause without digging deeper is premature. The USCRN\u2019s strength is its consistency, not its ability to explain every wiggle. What it does<\/em> tell us is that big swings still happen, even in a network built to filter out noise and bias.

Cue the inevitable spin: \u201cThis is just weather, not climate!\u201d Fair enough\u2014month-to-month changes don\u2019t rewrite long-term trends. But when the trendsetters clutch their pearls over every heatwave, cherry-picking highs to fuel the crisis machine, a record-breaking drop deserves equal airtime. The USCRN\u2019s full history shows no significant warming signal since it began, hovering around a flatline while global datasets scream \u201cunprecedented.\u201d Maybe it\u2019s time to ask why the U.S.\u2014with some of the best instrumentation on the planet\u2014keeps defying the script.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

For perspective, that November-to-December 2009 drop was a beast\u2014almost 8\u00b0F (7.58\u00b0F) in a single month, dwarfing typical seasonal shifts. February 2025 might not steal the crown, but coming in second (seen at left) with one month 7.13\u00b0F drop in a 20-year record isn\u2019t chump change. It\u2019s a reminder that nature still has tricks up its sleeve, and the USCRN is catching them in real time.<\/p>\n\n\n\n

So, while the NOAA climate establishment gears up for its next \u201cState of the Climate\u201d sermon, let\u2019s tip our hats to the data doing the talking. The USCRN\u2019s February surprise isn\u2019t a debunking of anything\u2014it\u2019s just a fact. And facts, as they say, are stubborn things<\/em>. Stay tuned for the final numbers, but for now, this is one cold splash of reality worth chewing on.<\/p>\n\n\n\n
