Are all birds shrinking with #climatechange? In the mountains of Tanzania we (@mwtingley + Bill Newmark) find that birds are actually increasing in body size over almost four decades! Check out our paper in @EcographyJourna (nsojournals.onlinelibrary.wi…) @UCLAEEB @UCLAlifesci

What a difference 40 years makes! Tale of two years, both strong El Nino’s. Left: 2023 Sept-Nov departure from normal. Right: 1982 same. You see the 1982 El Niño over the East Trop Pacific, but otherwise the globe is more balanced. That’s how much Earth has warmed in 4 decades!

First theoretical dissection of scale-dependent biodiversity change to its 3 parts + a big empirical example. Francois, thanks for all the patience, endless discussions, and hard work, I've learned a lot. Congrats for your 2nd PhD chapter published! onlinelibrary.wiley.com/doi/…

Breaking news!
The planet once again touched the 2.0°C barrier for a single day yesterday.
On tenterhooks awaiting the definitive graphic from @CopernicusECMWF

New paper out today! Male pathology can drive transmission without sex-based differences in behavior. Congrats @SauerScientist ! @AnimalEcology @UArkResearch

6. That's it, that's the tweet.
6. That's how many 'Akikiki there are in the wild now. How did these incredible creatures and their brethren come to be and why is now the moment of truth in their 5 million year old history?

Bird species' responses to habitat changes vary according to the geographical distribution range and local environmental suitability. See results obtained by a great group of colleagues with 81 Atlantic Forest species in sciencedirect.com/science/ar…

#NewPaperAlert! Stoked to share our pub on the migration phenology of songbirds tracked with the #MotusWTS network as they travel through North America in spring, now published in @AnimalEcology! besjournals.onlinelibrary.wi… 🧵

Someone casually said to me ‘I think you are focusing on the negatives and not the positives’. Yes, there are some positives but the reality is we are not turning this situation around. People cannot believe that our leaders would be doing so little if it really was that serious. That’s the whole point: people are protesting and going to prison, and scientists are screaming at us to act: because IT IS THAT BAD and none of our leaders are even acknowledging this physical scientific reality: #ClimateEmergency forbes.com/sites/davidrvette…

I was nervous posting my graphic showing 2.01°C because breaking 2°C is a huge event and I didn't want to get it wrong.
Then @LeonSimons8 posted the one below from Nov. 17 showing 2.06°C, and it relieved 100% of the stress.
Different data sets, same result. 2°C breached.

ΔT +2.06 °C !!
This is what uncharted territory looks like.
The first time that the global temperature anomaly has broken through +2.0 °C, for a single day in observational history.
Much more to come in the months ahead.

Yesterday, temporarily, planet Earth took its first step over the 2.0 degrees Celsius barrier.

This is huge. Governor Gretchen Whitmer will be signing legislation to transition Michigan to 100% clean electricity by *2040* & will create thousands of jobs in this industry. Great news for anyone who cares about combatting climate change. We need every Governor to do this.

Our little planet is now at 1.90°C above the 1850-1900 IPCC baseline.
The record high anomaly this year is 1.91°C, on September 22.
Tomorrow?

Excited that my new paper with Ryan Shipley is finally out today! We used 100 years of temperature data from 3,000+ weather stations and 300,000+ nest records to explore cold snaps and heatwaves during nesting for 24 common birds. doi.org/10.1038/s41467-023-4…
