I am a climate scientist and this is correct.

As the planet warms, storms like the one today are getting stronger… and as the Arctic is warming twice as fast as the mid latitudes, it increases the risk of the “freezer door” swinging open.

Happy New Year! I'm surprised to see springbeauty with flower buds in early January at northern Kentucky. Many are out with young leaves. They are responding to the recent false spring and wasting their energy. Unfortunately they don't know it will be very cold soon. 🙁 #phenology #falsespring

Heard about this a couple of months ago. Wish I knew it a bit earlier... 😅 Wonder if they can add that to past publications. @newphyt.bsky.social

When fall🍁 meets winter💦. After the first snow at NKU REFS on Nov. 11, 2025.

Sea pancake! Students voted to put it on our department t-shirt 😁 I always heard people saying they liked it when I wear it in conferences and events.

Some foliage colors at NKU REFS on Oct. 28 2025. More colors are coming.

Yingying Xie 谢莹莹 @yingyingxie.bsky.social · Oct 29

It sounds quite late in New England. Probably because the unexpected warming this fall delayed the timing of foliage coloration. We started to see beautiful colors recently with consistent cold nights.

Yingying Xie 谢莹莹 @yingyingxie.bsky.social · Oct 27

Brilliant fall foliage color of red maple, silver maple, sweetgum, and red oak from Cincinnati and northern Kentucky, although it's about two weeks later than expected 😁

Agreed. The urgency has never been emphasized enough. More specific guidance of actions is also needed. We have sufficient technology and resources to overcome the crisis but lack the social mindset transition and unity on a broad scale.

Thanks for the second image explaining this... I wouldn't know 😂

After steady rain, hundreds of white Amanita mushrooms come out at NKU REFS, same as last year! Larger than my hand. Have an unpleasant smell when it starts to decay. Are they North America destroying angel, Amanita bisporigera, one of most poisonous fungi? We got so many!😎

Wow. Makes so much sense as I really thought this September was the hottest one I ever had in my life. Not a good sign.🫤

Thanks for sharing the story of your predictions! Would love to hear more! One of research topics that I am always passionate!

Yingying Xie 谢莹莹 @yingyingxie.bsky.social · Sep 2

My favorite season is here. This year would be spectacular!

Here is my annual prediction of autumn colors in the eastern deciduous forest. Find out whether they will be bright or dull, and subscribe to Our Trees for updates over the season.

Myth #3:
Nature is a (trivial) subset of the human economy

Reality:
The economy is fully embedded in Earth systems

Implication:
Undervaluing nature erodes our long-term foundation

Thanks for your message! I don't know how the organizers decided, but they did a good job reminding us to have things prepared for the hot environment. This is literally my hottest conference ever! Desert ecosystem is amazing! 😄 Hope to visit Palm Springs in a better time again!

Yingying Xie 谢莹莹 @yingyingxie.bsky.social · Jul 27

Good morning! Palm Springs! Look forward to the field trip! #Botany2025

Still remember how worried I was one day in 2014 knowing CO2 got surpassed 400ppm when I was a grad student. Now feel even worse though not surprised showing higher and higher CO2 in the Env Sci courses to my students over semesters.

Yingying Xie 谢莹莹 @yingyingxie.bsky.social · Jul 11

And the loss kept increasing... look at the non-linear curves.😱

Yingying Xie 谢莹莹 @yingyingxie.bsky.social · Jul 11

Somehow while people say protect the environment, it sounds we are doing a favor to mother nature. NO! We are doing it because we are in danger and we are responsible for this! We should do the right things for us and our children and future generations! And we CAN make it right by doing NOW! (5/5)

Yingying Xie 谢莹莹 @yingyingxie.bsky.social · Jul 11

The stable climate is not just about temperature, but also few extreme events (e.g., droughts, heat waves, flooding, wildfires, etc.). Unfortunately, we already see the increasing frequency and intensity of them in recent years globally that cause huge damages, death, and economic costs. (4/5)

Yingying Xie 谢莹莹 @yingyingxie.bsky.social · Jul 11

The relatively cool and stable climate strongly contributed to agriculture that support growing human population and civilization. There was no human in the dinosaurs age with that warm climate, so how can we adapt when we never experienced? If we have to, what is the price, can we afford that?(3/5)

I always use this slide in teaching Env Sci courses. Some people think the current rising temperature is ok because it happened before. But that warm period or dinosaur era is NOT relevant to human. What really matters to us is the stable climate that contributed to successful agriculture. (2/5)

Yingying Xie 谢莹莹 @yingyingxie.bsky.social · Jul 11

We should talk about global climate change within the context of human history. We aim to protect humans while protecting the environment. Mother nature will be ok eventually, but NOT us. After replying a post from a climate change denier, I realized I should post here so more people can see (1/5).

I've never seen this before! Antlered flutter fly. So cool! Is this a mating dance? Yesterday evening at NKU REFS.

Encouraging and phew.. sometimes, it just takes more time than expected.
