I do numerical modelling of ice sheets, iceberg calving and sea ice melange at PIK, exploring their role in climate change and our planet’s future.

‘Glaciers in Icelandic history were in the context of eternity,’ explains the Icelandic writer and environmental activist Andri Snær Magnason. Today’s Video explores the rapid decline of these ice caps and what it means for Magnason’s connection to his family history

To carry 50,000 people per hour in each direction, a city needs a 175m wide road for cars. Even if those cars are electric. And then there’s all the parking. OR a city can move A LOT MORE people in a lot less space, with A LOT LESS public money, emissions, pollution, noise etc. Choices. Simple.

Graphic showing a 9 m wide track for metros can move as many people as a 175 m wide, 7 lane road for cars.

Oh dear we're going to overshoot, but don't worry we don't need to urgently stop burning fossil fuels we can... use bioenergy with carbon capture and storage. Scientists: We've taken another look & "most emissions occur before the power plant and therefore cannot be captured"

Governments are considering subsidies for bioenergy with carbon capture and storage fuelled by wood from existing forests. However, a transparent model estimates that this will probably increase emiss...

As the world rapidly heads into #climate #overshoot I've noticed a disturbing pattern in journal articles recently. I'll summarize it quickly in this thread 🧵

I’d like to make it clear for all the people following me what the sheer gravity of the news is. Without this facility we can’t ensure constant communication with spacecraft beyond Earth orbit. If this facility is off-line, the Artemis program cannot send a crew to the Moon.

"The melting of land & sea ice are expected to increase over the coming decades, resulting in an enhanced freshwater discharge into the N. Atlantic. With stronger freshwater anomalies, our results indicate an increase in the risk of warm, dry European summers & of heat waves & droughts accordingly"

Abstract. Amplified Arctic ice loss in recent decades has been linked to the increased occurrence of extreme mid-latitude weather. The underlying mechanisms remain elusive, however. One potential link...

🌊 New Antarctic research shows the deepest layer of the Southern Ocean – Antarctic Bottom Water, or AABW – is shrinking faster than scientists realised, with the rate of change accelerating over the past decade. This is important because we all depend on it. ▶️ aappartnership.org.au/antarctic-ch...

In my lifetime, I've seen segments of society lose trust in evolutionary biology, climate science, and vaccines. None of this was due to anything scientists did. All of it was because non-scientists perceived some advantage (political, cultural, financial) in attacking science's credibility.

"Thwaites is really the biggest player, the biggest wild card in sea level rise in the future." CIRES' Ted Scambos talked about the missing ice in Antarctica’s west coast and Thwaites Glacier with Living on Earth. @colorado.edu www.loe.org/shows/segmen...

Midsummer in the Northern hemisphere marks the dead of winter in Antarctica, usually a time when temperatures plunge and the surrounding ocean ices over, nearly doubling the continent’s size. But…

With all the July model runs now in, it is very likely that 2026 will see the largest El Niño event since records began in the late 1800s – and potentially by a truly mind-blowing margin. The median estimate is now 3.6C, roughly 0.8C hotter than the prior record (2.75C). www.theclimatebrink....

Great interview w Naomi Oreskes "The right wing, the fossil fuel industry—what I call “the carbon combustion complex”—they understood the science only too well, and they understood very clearly what was at stake. And because they understood it, they fought the science tooth and nail." 1/

On Climate Denial and Free Market Fundamentalism

The failure to respond to decades of scientific evidence regarding climate change is examined through the lens of free market fundamentalism and the systematic loathing of government intervention. Thi...

Climate.us is a great place to explore. So much was lost with the destruction of climate . gov and climate.us is making sure we have data, tools, and insights. 🙌

What is Climate.us? It’s a new independent, nonprofit climate information website with a simple goal: keep trusted climate science easy to find, easy to understand, and available to the public. Climate information is a public good. Climate.us is here to help protect it. Explore Climate.us 🌍️ 🧪

I really like this because it also helps people become more familiar with how our climate future works. There's no science crystal ball, but we sure do know a lot and people can plan and act using that information. Insight instead of certainty.

What if the future of weather forecasting isn't about finding one "right" answer? A new CIRES and @noaa.gov forecasting experiment found that explaining why a forecast is uncertain — and when confidence will improve — helps people make better decisions.

Scan your local news today. How many stories are about something climate change is making worse...without saying so? I counted 8 of those in my feed today, vs just 1 that named climate change directly. Why does this matter? Research shows that making this connection changes how people see it.

Nine screenshots of my google news page today, each describing issues that are directly impacted by climate change, from more dangerous wildfire to changing flood policies.
