Ditto.

In honor of Sir David Attenborough: "There, perfect in every detail, glinting as though it had just been polished, was a coiled seashell… an object of breathtaking beauty, and my eyes were the first to see it since its occupant died 200 million years ago." Happy 100th, Sir David! #FossilFriday 🦖⛏️

And a hopeful quote from the same amazing human: “In my lifetime I’ve witnessed a terrible decline. In yours, you could and should witness a wonderful recovery.” - UN COP26 We can do it, fellow humans. Let's stop being a plague and start being citizens of Nature. 🌎 Happy birthday, sir David!

Happy 100th, Sir David Attenborough! A quote from 2021 to the United Nations COP26 climate meeting: “In my lifetime I’ve witnessed a terrible decline. In yours, you could and should witness a wonderful recovery.” Let's make this birthday wish come true. #Conservation #6thExtinction 🦖🦤🧪🌎

Join #ClimateCentral for the next Monthly Climate Brief! We’ll explore the latest climate trends – including updated El Niño forecasts and long-term snow drought impacts. 📅Thursday, May 14, 2026 ⏰12 PM ET / 9 AM PT Register ➡️ climatecentral-org.zoom.us/webinar/regi...

Climate Change is here. How will you help protect our earth ?

Temperate and tropics only in this graph; not included are the rapidly increasing polar oceans.

Ocean currents not only influence climate but they also keep ocean ecosystems healthy. Shutdown of ocean currents = stagnation of ocean = extinction of species. This is the first current that could go. Once they are off, it's centuries to millennia, before they start up again. 🧪🦤🌎 #6thExtinction

Breaking News! Code: y-axis alert! As of the latest Nino 3.4 anomaly forecast dated May 1, 2026, the y-axis has been extended to now include the possibility of a +4°C El Nino. The coming El Nino may turn out to be the strongest ever recorded. Stay tuned!

Addressing non-CO2 GHGs alongside CO2 is essential for climate mitigation, but distributional effects remain a major concern. Now a study shows that when climate policy extends beyond CO2, the resulting costs are unevenly distributed across households worldwide. www.nature.com/articles/s41...

Even way up north in northern Canada, we are not looking forward to this El Nino. Not a bit. Why? 🔥🔥🔥🔥 A big part of the Earth's "lungs," the boreal forest, is in danger from a tropical oceanic event. #ConnectedEarth 🧪🦤

Emissions lead to global warming. Warming leads to many things, but this...100s to 1000s of years to recover, if at all. Many mass extinctions occurred during or because of an end to ocean mixing. #6thExtinction #ClimateChange #GlobalWarming #Oceans 🧪🌎 interactive.carbonbrief.org/amoc-explain...

Well said.

The scale bar is *only* 1C. 1C rise on this scale in a very, very short time frame from a geological perspective. This is mass extinction-scale climate change. 🌎🧪 #ConservationPaleobiology #CPB #6thExtinction #ClimateChange

Lichens Are Beautiful! There are two examples of lichen in the much younger Oligocene Baltic amber. The oldest fossil lichen is about 400 million years old (Devonian) from the Rynie Chert in Scotland. (Source: UCMP + refs therein). Lichens are probably even older! #FossilFriday #Fungi 🧪🌎🦖

Extinction isn’t random. Range size matters. Temperature tolerance matters. Climate change matters. But there’s another piece we’ve long suspected: geography. For 500 million years, the shape of continents helped shape survival. 🧪 #SciComm buff.ly/rPvvUEM

HAPPY 5-(🌎)YR LANDIVERSARY to our Perseverance Rover 🍰 As a Jezero mapper, seeing the *image* from SkyCrane of M2020 being lowered to the crater surface, will forever be a highlight of my career. CONGRATS to the entire M2020 Team (extra special shoutout to the EDL engineers!) 🧪🔭 #PlanetarySci

The Trump Admin's repeal of the Endangerment Finding is brazen denial of climate science that puts polluters before people. We will continue to fight this in every way we can.

If all Earth’s ice sheets melted, sea level would rise ~65m over millennia But just 1–2% of that (~65–130 cm) would force chronic flooding & retreat in many coastal cities ~1 billion people live within 10m of sea level (~15% of total) The risk isn’t the end state, it’s how little change it takes!

The irony of ICE expanding and polar ice contracting is not lost on me. Naked fascism in an effort to control climate-driven migration in the US just wasn’t what I expected.

Anthropogenically-accelerated climate change is ultimately leading to a warmer Earth faster than is natural, but the process is one of chaos and instability, like our recent deep-freeze and snowfall in the U.S. and Canada. #ClimateChange🧪🌎
