Our forecast of the atmospheric CO2 rise for 2024 is out 🧵 To limit global warming to 1.5°C, the build-up of CO2 in the air would need to stop very soon But with a rise of 2.84 ± 0.54 ppm expected this year, there's no sign that the CO2 rise is slowing metoffice.gov.uk/research/clima…

Just updated my visualization of changes in land ice mass as observed by GRACE(-FO) satellite in #Antarctica (left) and #Greenland (right) 🧊📉 Methods can be found from ARCHIVED - NASA Climate at climate.nasa.gov/vital-signs/ic…. My graphic can also be downloaded: zacklabe.com/arctic-sea-ice….

The International Energy Agency's Electricity 2024 report is out today. It expects clean power – nuclear and renewables – to cover all extra electricity demand over the next 3 years. At a global level (not in every country). iea.org/reports/electr…

As battery #ElectricVehicles sales in Norway reached 82% market share last year, it's remarkable how predictive this simple model ended up being.

A manual reading at Achfary, a site in northwest Scotland, has come in today with a temperature of 19.9 °C on Sunday, provisionally setting a new UK maximum temperature record for January This exceeds the automated reading of 19.6 °C reported yesterday at Kinlochewe

In light of mounting concerns over carbon credit integrity and the imperative to align #offsetting practices with #netzero goals, today we publish the *Revised* Oxford Principles for Net Zero Aligned Carbon Offsetting. smithschool.ox.ac.uk/sites/default/…

Absurdly warm in Central & North America. Many places recording their warmest February temperatures on record in the last few days... Colder air racing in from the north now though reminding us that it is indeed still February...

🏆📈🏆  Earth’s atmosphere just hit 427.93 ppm #CO2 on March 15, 2024 🏆 HIGHEST EVER daily average at MLO 🏆 Up a whopping 7.69 from 420.24 a year ago 🏆 NOAA: gml.noaa.gov/ccgg/trends/mo… 🌍 CO2.Earth: co2.earth/co2-records 🌍😰 Keep the 350 ppm overshoot brief!!

As El Nino gives way to La Nina, we're seeing a drop-off in global sea surface temperatures (as some of us said would happen). The problem was never about one or two years--it's about the TREND. Planet will continue to warm until carbon emissions reach zero. Truth is bad enough!

IPCC climate model projections compared against latest (Berkeley Earth) global temperature observations (via @Hausfath). We're seeing the predicted steady warming. The warming will continue as long as carbon emissions continue. That's entirely up to us. #UrgencyAndAgency

The ship has largely sailed on limiting warming to 1.5C at this point, barring us getting very lucky with low climate sensitivity or actively geoengineering the climate. But there still are viable paths to limit warming to below 2C this century, as shown in the figure below:

March 2024 was the 10th month in a row globally to be hottest on record.

How much of global warming is human-caused? MORE THAN 100% That’s right: according to natural factors, including the sun and natural cycles, the Earth should be slowly, gradually cooling right now. Instead, it’s warming. m.youtube.com/watch?v=k5_zpj…

We are likely to regret not acting sooner. theconversation.com/my-new-dark-re…

A molten salt photothermal power station enters operation in Qinghai, China 🇨🇳. These are more expensive to build than a typical solar farm but generate electricity 24 hours each day.
