Please listen a few minutes to Andri Snær Magnason. He has a message from Iceland. youtu.be/hdvYezsK70A

Did you ever wonder: What does 3°C of global warming mean for us? My new open-access book chapter explains it. For over 30 years, I've worked in oceanography, paleoclimate & extreme weather research. link.springer.com/chapter/10.1...

I’m loving this variation on a cycle plot published by the Financial Times today: www.ft.com/content/8e83... By Jana Tauschinski

Almost five years since this classic was written www.vox.com/the-highligh...

What is the current level of global warming: * 1.2°C average of the last 10 years * 1.3°C last datapoint in the 15 year trend * 1.5°C last datapoint unadjusted (in one dataset) Great figure, amongst many others, open for peer review: essd.copernicus.org/preprints/es...

A lot of folks have been fixated on changes to sulfur in marine fuels of late, but the much bigger climate story here is the nearly 50% decline in overall global emissions of planet-cooling sulfur dioxide since 1980 – much of which has happened in the last 15 years:

Is the Atlantic Ocean circulation #AMOC approaching a tipping point? This lecture is my take after researching this topic for over 30 years, and receiving the Alfred Wegener Medal of the European Geosciences Union for my scientific achievements last week. Grab a cup of tea! youtu.be/HX7wAsdSE60?...

Theres an important new study from many of the leading researchers on paleoclimate and climate sensitivity. They provide a new, more robust estimate of climate sensitivity from the last glacial maximum, suggesting a sensitivity of 2.9C (95% CI: 2.1 to 4.1C): www.science.org/doi/10.1126/...

Best wishes to @ceresbarros.bsky.social on her first day of work at the Canadian Forest Service! It is a joy to work with Ceres, a brilliant scientist and a true team player.

The rate of warming has increased notably in recent years. This is not just natural variability – the world is now warming faster than it has since 1970. However, this should not come as a surprise; acceleration is exactly what our models expect: www.carbonbrief.org/factcheck-wh...

Is there a big disagreement on whether we expect climate change to accelerate (in the absence of large changes in emissions)? Not so much! www.realclimate.org/index.php/ar...

Data is out from Copernicus Climate for the boreal spring/austral autumn solstice and the global temperature records continue for both air and sea surface temperature 👉check out pulse.climate.copernicus.eu #climatecrisis ⚒️🧪🌍 #earthsky

We usually compare GHG emissions and temperatures to pre-industrial times, often considered to be 1850-1900, partly because good records start aroung then. But Japan has kept good records of peak cherry tree flowering since 812! ourworldindata.org/grapher/date...

The annual atmospheric increase in CO2 was a whopping 3.4 parts per million (ppm) in 2023. Sure, it was fueled by El Nino, but I don't think anyone had on their bingo cards this large an increase. gml.noaa.gov/ccgg/trends/... 1/

Its a weird bit of whiplash going from arguing with folks claiming models are warming too fast a year ago (no warming since 2016!) to folks arguing that models are warming too slow today. One year does not a trend make, and models are by and large doing ok:

Climate policies focus on limiting global warming to a given level (e.g., 1.5°C), but the climate modeling community does not have an experimental design for models to stabilize at a prescribed warming level. Until now... Review comments welcome: egusphere.copernicus.org/preprints/20...

Your regular reminder that the world is still not doing nearly enough to avoid dangerous warming If we'd started in 2000, emissions cuts of 3% a yr would have kept us below 1.5C Now, they must fall 18% *every yr* – or we have to use "negative emissions" www.carbonbrief.org/unep-humanit...

The record global temperatures are caused by global warming, with a lot of the signal coming from the ocean. But it isn't just El Nino warming the ocean surface. Compare this year (top) and previous El Ninos (bottom) - N Atlantic, NE Pacific and SW Pacific aren't usually warm during El Ninos.

Its now official: 2023 was the warmest year on record in the JRA-55 dataset, at 1.43C above preindustrial levels. It beat the prior record set in 2016 by 0.14C, and continues a rapid warming trend thats seen global temperatures rise around 1C since 1970.

I wrote a pair of short blog posts on the climate value of temporary carbon storage, now available at the Kleinman Center for Energy Policy at Penn. Part 1 explains why temporary offsets are *not* equivalent to the permanent harms of CO2 emissions.

Scientific institutions must create--and sustain--new kinds of roles so that researchers can provide the deep public engagement necessary to respond effectively to the escalating impacts of #climate change. The status quo isn't working. [Thread: 1/n] www.nature.com/articles/d41...

"Declarations that 1.5 C is dead make no sense. Global temperature limits don’t die if we surpass them. People do." One of the best things I've read on this issue. Featuring my fantastic colleague @adellethomas.bsky.social 👇 www.scientificamerican.com/article/meet...
