Will you see a white Christmas this year?

For most of the U.S.: Nope. 🫤

Still, here are the historical odds 🎁

The tradition of #Festivus begins with the airing of grievances…

…this year’s: unusual, near-record late-December warmth for over 69 million people across the U.S. will walk out the door to today, made more likely by climate change.

As 2025 wraps, we’re looking back at some of the Climate Central team’s favorite Climate Matters from the past year.

From memorable graphics to go-to story resources, these are the releases that stuck with us.

🧵Let's stroll through the resource library ⤵️

Record heat was tied or set in over a dozen states Sunday.
More are expected today.
Daily records are at risk during this holiday week.

Climate Shift Index shows this 15°-25°F+ above average December warmth has a strong climate change fingerprint...and in some places would be rare without it.

❄️Today (December 21) marks the first official day of the Winter Season.

Winter isn't what it used to be for generations past.
The season has warmed, on average by 3.9°F, in 98% of 244 U.S. cities.

In our warming world, the coldest days aren’t as cold, and cold snaps don’t stick around as long

A chilly December so far, but the holiday is bringing some heat

Forecast warmth on Dec 24–25: temperatures running 20°–35°F above average

Climate Shift Index shows this kind of Christmas warmth is *at least* 2x to 3x MORE likely because of human-caused climate change.

There’s some debate about where the jolly ol’ elf 🎅 lives, but in Longyearbyen, Svalbard, where local legend places Santa’s workshop, it’s looking more ♨️toasty than☃️frosty for this time of year.

Climate change may have Santa breaking a sweat, and the sleigh runway could be a little… slushy.
December 18, 2025 at 9:22 PM
High Wind Warnings are in effect across more than a dozen states Wednesday and, in some areas, into Thursday.

💨 Gusts of 70–90 mph are possible, raising concerns for hazardous travel, reduced visibility, blizzard conditions in colder regions, and high fire weather risk.

Ho. Ho. Oh no…

A not-so-cool Yule is shaping up for much of the Lower 48. Many heading over the river & through the woods will feel temps 20°–30° ABOVE average

Not the Christmas story every year (yet), like a stocking full of coal, climate change has made Santa-sweating heat like this more likely.

What's one thing we can all do in the fight against climate change? Talk about it, as daunting as that may seem!

Because people care about climate change (and want to talk about it) more than you probably think.

Looking back at 2025 (through mid-December): a snapshot of the climate fingerprint on the UK’s unusual, at times excessive, heat.

The Climate Shift Index signal ramps up in spring, then flickers on and off in waves into early September. Notice how it shows up again throughout November.
December 16, 2025 at 6:36 PM
🥶Festive cold in the East
♨️but for the West, mid-December warmth running 15°–25° above average.

Climate Shift Index shows us:
• Deep cold like this - less likely in a warming world
• This western warmth is made 2x to 5x more likely due to human-caused climate change

🧵 It's hard to believe but 10 years ago today the Paris Agreement was signed at COP21🌎

Where are we at in 2025? Projected warming this century has dropped from ~4°C in 2015 to 2.6°C today, if current emissions reduction pledges are implemented. But a lot more work is needed!

🧵 This week's Climate Matters dives into 5 ways that carbon pollution 🏭 disrupted lives in 2025.
www.climatecentral.org/climate-matt...
1. Carbon pollution made 89% of U.S. record highs more likely. Over 4x more record highs than record lows (298) were set across 247 U.S. cities through November.

Flood Watches & Warnings are posted across Washington and Oregon this week as an atmospheric river impacts the Pacific Northwest.

⚠️Heavy rain, strong winds, and the risk of landslides are all on the radar.

Let’s break down how climate change plays a role in events like this 🧵

TODAY! ⏰12pm ET

Join us & @coveringclimatenow.org to unpack how climate change is reshaping winter, from warming temps to shrinking cold snaps.

Most cities now see at least one extra week of above-average winter days vs 1970. Come find out why that matters!
