I will retweet any photo of the #tuatara (#Sphenodon) provided the descriptive text doesn't include: #livingfossil, #lizard, or #dinosaur

When images of glacial retreat are posted online it's amazing how many people's gut reaction is "summer vs winter!" without any consideration for latitude + light levels or knowledge of actual glaciers. #ChristianAslund #Blomstrandbreen

2 photos of the arctic both taken in the summer more than 70 years apart show the dramatic change in the continent ice cover. There is no time to waste. No planet B. #ActOnClimate #ClimateEmergency #climate #phaseoutfossilfuels #renewables #GreenNewDeal pic via @ChristianAslund
The month of #June was marked by severe #weather events around the world A thread 🧵 1/2 #Flood #Hurricane #Storm #Earthquake #Volcano #Eruption #Tornado #Wildfire #Asia #Africa #Europe #MiddleEast #China #India #Turkey #France #Italy #SouthAfrica #Mexico #Peru #Climate #Viral
If journalists in Scotland get a chance to interview Trump when he visits Scotland, ask him why he denies human induced climate change yet asked for money to build a sea wall to protect against accelerating sea level rise for his golf course in Ireland. See next tweet
🧵 As Trump arrived in Scotland on a private golf visit (& Scotland gets the bill) he complained about wind turbines, YET ignored that water intensive golf courses take up more land (1,256 sq km) than all the solar panels and wind turbined combined! St Andrews has 12 courses!
#climatebrawl Heat isn't temperature- heat is the transfer of random kinetic energy of a system, the capacity to transfer can be measured from a baseline. Our oceans are constantly exchanging heat with our atmosphere, direction changing based on ΔT at the boundary between them.
As a reminder, here's your opening post, attached. Note that it is clearly labeled to say "Number of Days in the Year Daily Global Mean Surface Temperatures Exceeded 16.8°C" (~62°F), and it shows values for 1950. Note that it depicts Temperatures, not Heat.
Tré-la-Tête Glacier 2009 | 2025 Glacier collapse in the Alps is so rapid that it is leaving behind glacier tongues that have been cut into several pieces 🧊🔥 See what the former front of one of the largest glaciers of the Mont Blanc Massif now looks like... 😰 1/
Bjorn Lomborg (the climate action delayer, who is paid approx. half a million dollars a year to mislead) is caught out yet again. Renewables make electricity cheaper as show by @AndrewDessler and @zeke :

I am proud and grateful to present a dream project today in @Nature! nature.com/articles/s4158… Meet #Mirasaura grauvogeli, a #wonderreptilewith skin appendages that rival feathers and hairs, challenging our view of reptile #evolution🪶🦎
Mer de Glace has lost 4.5 m in thickness at the level of the ice cave (1750 m) since the 1st May 2025! 😲😱 On 5th July it has been recorded 5 cm of ablation in 5 hours... 🔥 Ablation rates are truly absurd now in the Alps! 🥵 Source/pics: Pierre Jeanneret / IG
Have you seen people pushing this figure, which purports to show that renewable energy raises energy costs? It's BS.
We've known for over a century exactly how higher atmospheric GHG concentrations raise surface temperatures. It's quite literally basic physics at this point. It's hilarious how many willfully ignorant idiots still refuse to accept that fact. Peak denial. x.com/e_philalethes/…
We've understood for well over a century how GHGs like CO2 absorb LW radiation emitted by Earth and cause surface warming. We've emitted massive quantities of them since 1850. We can quantify the radiative forcing from it, and even measure the resulting energy imbalance directly.

Who's in for the U.K. butterfly count?
Whilst I am on a roll with neoliberalism, I want to spell out how I think this neoliberal agenda was laid out in a very corrupting and manipulative fashion. I have never seen or heard anyone else say this. This was derived from my own contemporary observation. 1/🧵
Yes, X's algorithm deprioritizes posts with external links to encourage in-platform engagement, as confirmed by Elon Musk and recent analyses (e.g., 2025 SocialBee report). This can reduce reach by up to 94% per tests. To maximize visibility, share links in replies or use X's…
Not one climate scientist. Literally anyone can go to your website and sign the petition. It's also ironic because you all say consensus doesn't matter as much as evidence, yet here you are doing the complete opposite.
I want to expand this, as it seems a lot are not getting what I'm saying and why. The vast majority of the public, have no idea what neoliberalism is, or that the mainstream parties they vote for, all adhere to neoliberal ideology, as they don't declare it, and deny it. 1/🧵
I have just come up with an idea for how to unify a progressive alliance. It could be called something like "Oppose Neoliberalism", and be a declaration of common cause, in opposing neoliberalism. 1/🧵
