AMOC Tipping Risk: From Low Probability to Urgent Concern
For thirty years of my career studying this, I considered the #AMOC tipping risk a high impact but low probability risk for the future of humanity. Recently I've changed my mind. Here I explain why. ⬇️ https://t.co/DfLsJ5ezCb
Moderate Emissions Keep Earth 3‑4°C Warmer by 3000
We are in the Age of Humans - the Anthropocene. Our new article (open access) shows how even with a moderate future emissions scenario, global temperature will still be elevated by 3-4°C in the year 3000! Lifetime of our CO2 in the...
AMOC Collapse Threatens Northern Europe's Food Security
I often get asked: what impacts would a shutdown of the Atlantic ocean circulation #AMOC have? A short overview is found in this expert report. Impacts include e.g. widespread domestic food insecurity in Northern Europe and strain on global food...
Ocean Circulation Tipping Threats Accelerating, Documentary Shows
This BBC documentary by Jonathan Renouf on abrupt climate change due to ocean circulation tipping is one of the best. From 1999, with top experts like Overpeck, Alley & the late Wally Broecker, it's chillingly current: that risk looks much higher...
Aerosol Removal Slows AMOC, Confirming New Scientist Findings
A new study by Allen et al. shows just what the New Scientist headline says. That's in fact not unexpected: warming slows #AMOC, and that's what removing aerosol pollution does. 🌊 New Scientist 👉 https://t.co/QyoJjdrjSE The paper 👉 https://t.co/u17MNaPKDC
Scientists Warn: Atlantic Ocean Circulation Instability Rising
Why are scientists more concerned than ever before? DW TV has a clip on the risk of instability of the Atlantic ocean overturning circulation #AMOC. https://t.co/bhQLuQfK6z
Atlantic Current Slowdown Threatens Climate and Weather Patterns
A key Atlantic current is weakening. Here’s why it matters. | DW News (with an interview with me). https://t.co/e2m3LlEapg
AMOC Tipping Point Threatens Future Climate Stability
Confused by media reports about the tipping point of the Atlantic Ocean's overturning circulation #AMOC? Carbon Brief has an excellent explainer about a serious risk which might strongly impact your future: 🌊 https://t.co/wWZxioObdr
Cold Atlantic Blob Tied to AMOC Weakening
And studies have linked that “cold blob” over the Atlantic west of the British Isles to that… #AMOC
Fossil Fuels Threaten Atlantic Circulation, Global Climate
Excellent overview over the risk of major ocean circulation changes in the Atlantic as a result of fossil fuel emissions, strongly impacting climate around the globe. #AMOC
More Atlantic‑Nordic Exchange Signals Weakening AMOC
Does a stable or increasing water exchange between the Atlantic and the Nordic Seas mean the #AMOC is stable, as some have argued? 🌊 Nope. The opposite is the case. https://t.co/G5gxvLcQ5O
2015 Study Shows Unprecedented Atlantic Circulation Slowdown
The journal Nature Climate Change is celebrating its 15th birthday by looking back at highlights from this time. I'm honored that our 2015 paper "Exceptional twentieth-century slowdown in Atlantic Ocean overturning circulation" is first in the series 🌊: https://t.co/HJ4kAOjyVt
Western Overturning Circulation Drops, AMOC Nears Critical Tipping Point
New study finds "canary in the coal mine" for the #AMOC: a consistent decline of the western overturning circulation, down from 20 to 15 Sv during 2004-2023 at 26° N. AMOC "could be at or near a critical tipping point, potentially...
Glacier Melt Proves Global Warming, Not Urban Heat Bias
Glacier ice loss is a global & well-documented phenomenon, including from the Greenland and Antarctic Ice Sheets. A very visible result of #globalwarming. But I’ve seen climate deceivers recently claiming warming is due to the urban heat island effect 🙄🤯…
Climate‑skeptic Diagrams Don’t Survive Scientific Scrutiny
If you see one of the diagrams on the internet that supposedly disprove #globalwarming or climate models, they invariably are aimed at lay people and don’t hold up under scrutiny. 🧐 Here’s an example (a cherry 🍒 pick) by notorious...
