The past week has been busy as the station infrastructure is installed, providing kitchen and amenities buildings independent of the traverse facilities. Camp with newly constructed kitchen and mess in the centre. 📷 D. Beloin /..
MYIC DCN camp, aerial view. Traverse vehicles and vans are seen alongside vans for amenities and sleeping and the new kitchen and mess shelter. The large drill tent is seen at the far right.

The camp looks in great shape after the cold and lonely winter. Some drifts outside but no snow inside the shelters. Ice coring team members are standing by at Casey Station to fly in via Concordia as soon as weather permits. Stay tuned! 📸 D. Harvie

Australian Antarctic Program Traverse team rolls into Dome C North! The 1168 km journey was completed in 17 days 🚜⚡️. A superb result so early in the season.. months of teamwork and planning! A moment to celebrate before we move to setting up our ice core drill system! 📸 D. Harvie, A. Doherty,

Two important attribution studies were published today. I covered both for @carbonbrief.org 1️⃣ Shows that heat/drought extremes are overwhelmingly caused by the wealthiest 10%: buff.ly/0Se78bM 2️⃣ Finds that younger generations will face "unprecedented exposure" to climate extremes: buff.ly/Qxw80Un

Two-thirds of global warming since 1990 caused by world’s ‘wealthiest 10%’ - Carbon Brief
Of the 0.61C increase in global average temperatures over 1990-2020, a new study estimates that 65% was due to the emissions of the wealthiest 10%.

1. This is a thread about Horticultural Extrapolation. Not something you're likely to have thought about, but it's time some people did. What is it? It's projecting the mechanics of fruit and veg growing onto the entire food system. It's surprisingly common, and frequently leads people astray. 🧵

🚨 I have another record to share - carbon dioxide (CO₂) averaged a record high of 428.2 ppm in March 2025 10 years ago March averaged about 401.7 ppm Provided by gml.noaa.gov/ccgg/trends/. Climate monitoring and data like this are at risk. #StandUpForScience
Red line graph time series of monthly carbon dioxide abundance from January 1959 through March 2025. There is a seasonal cycle and long-term increasing trend. Current levels of CO2 are at 428 ppm. This is the Keeling Curve graph. A line for CO2 10 years ago is also annotated.

The amount of sea ice currently on our planet continues to set new record lows for this time of year... More visuals at zacklabe.com/global-sea-i.... Data from @nsidc.bsky.social for the satellite-era period.
Line graph time series of 2025's daily global sea ice extent in red shading compared to each year from 1979 to 2024 using shades of purple to white for each line. There is substantial interannual and daily variability. Seasonal cycles are visible. Note: the poles are affected by very different Earth system processes/seasonality. I am using 5-day running mean data.

Based on carbon budgets from Lamboll et al www.nature.com/articles/s41... - updated to January 2025, the global rate for cutting CO2 inline with a 50% chance of not exceeding 1.5°C is ~19% year on year. For "well below 2°C" its ~7% each year; i.e. a technology revolution AND profound social change.

@aukehoekstra.bsky.social did some studies 4 years ago which found that the CO2 break-even point for an EV was 25,000km (16,000 miles). Any additional driving over 25k km resulted in emission reductions over the total lifecycle of the car. Obviously we'd expect all cars to drive more than 25k km.
The total of greenhouse gas (GHG) emissions, depending on kilometres driven, from Polestar 2 (shown with different electricity mixes), and Volvo XC40 internal combustion engine (ICE).
Where the lines cross, break-even between the two vehicles occurs.
All life cycle phases except use phase are summarised and set as the starting point for each vehicle
Based solely on an analysis of Polestar 2 (model year 2020) and Volvo XC40 petrol internal combustion engine (model year 2020).
The data in this chart was either traced from an original chart from "Polestar Life Cycle Assessment: Carbon Footprint of Polestar 2" or provided directly by Auke Hoekstra @AukeHoekstra. The horizontal axis from the Polestar publication did not use tick marks, as replicated here, so that it was difficult to determine a precise location of the proper break-points. I decided to repeat that, so as not to distort any prior representation.

The graph below shows the lifecycle greenhouse gas emissions from Internal Combustion Engine (ICE) vehicles and EVs. The embodied carbon from battery manufacture is yellow in the graph. You can see that it’s dwarfed by the emission savings from driving EVs compared to ICE vehicles.
Figure ES.1. Life-cycle GHG emissions of average medium-size gasoline internal combustion engine (ICEVs) and battery electric vehicles (BEVs) registered in Europe, the United States, China, and India in 2021 and projected to be registered in 2030. The error bars indicate the difference between the development of the electricity mix according to stated policies (the higher values) and what is required to align with the Paris Agreement.

Saturday ice update - #Arctic sea ice extent is currently the *lowest* on record (JAXA data) • about 790,000 km² below the 2010s mean • about 1,450,000 km² below the 2000s mean • about 2,040,000 km² below the 1990s mean • about 2,430,000 km² below the 1980s mean Plots: zacklabe.com/arctic-sea-i...
Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between January and April by looking at the decadal average line positions.
