There is increasing talk about overshoot of 1.5°C, particularly that *now* we can only achieve 1.5°C by first overshooting 1.5°C.
Well, sorry to tell you, 1.5°C have always been overshoot scenarios. Here from the original 'SSP' 1.5°C scenarios published in 2018.

As part of the GCP-Regional Carbon Cycle Assessment and Processes-2, we recently published the Australasia's CH4 and N2O Budgets. The carbon budget was published in 2023, both papers, led by Yohanna Villalobos and a great team of collaborators.

New assessment on the biophysical potential of forestation to sequester carbon. As expected, we found just a fraction of what other assessments found, because we considered the obvious no-nos, such as risk to biodiversity, excess water use, and regional warming.

The climate case for planting trees has been overhyped — but it’s not too late to fix it
Reforestation can contribute significantly to tackling climate change, but research found its global potential is only a fraction of what’s been claimed.

A new study, led by Matthias Cuntz and our dearest late Vanessa Haverd, shows beautifully how the increase of the seasonal variation in atmospheric CO2 in the Northern Hemisphere over the past 40 years can only be explained by an increase in the CO2 uptake by plants.

Around 250 million years ago, Earth was near-lifeless and locked in a hothouse state. Now scientists know why
The answer confirms scientists’ suspicion that when our planet’s climate crosses certain ‘tipping points’, truly catastrophic ecological collapse can follow.

There is so much discussion about TIPPING POINTS, yet there are so few current large-scale examples that have been demonstrated quantitatively.
Xiaojun Li et al show a remarkable shift from accumulating carbon in living biomass in the northern temperate regions to losing carbon since 2016.
