4/ The captain doesn’t know the iceberg’s depth or how the hull would react. Similarly, temperature projections are uncertain. But uncertainty isn’t ignorance and shouldn’t excuse inaction. It should drive us to act on what we can control: the ship’s turning radius—our greenhouse gas emissions.

3/ The ship hasn’t completed its turn (orange: emissions still rising), but change has begun. Compared to ten years ago, the worst risks (red) are less likely. Recent pledges lower risk further (yellow), yet we remain in dangerous waters. To reach safer zones, the turn must accelerate (green).

2/ Imagine a transatlantic liner at full speed: that’s the global economy. Emissions set its course. Scientists spot a huge iceberg and raise the alarm. After long discussions, just like at climate conferences, the danger is acknowledged and the collective decision is made to steer the ship ...

With a mixed-results at COP30 - i.e. good intentions but no concrete plans for the “transition away from fossil fuels” - don’t give up.
Let’s remember the progress made since the Paris Agreement and the options ahead of us. That’s the message of the image below

Quando la scienza si piega alla politica: il negazionismo climatico nel rapporto del Dipartimento dell’Energia USA

@giacgrassi.bsky.social e @caserinik.bsky.social fanno a polpette il rapporto dei 5 negaioli per il DOE. Sono stati più veloci del solito, ma gli argomenti di quei "mercanti di dubbi... sono già stati più volte confutati anche su Climalteranti."

🤔 However, land use remains a blind spot in tracking progress under the #ParisAgreement, mainly due to inconsistencies between global models and country-reported data.
💡 It is crucial that future #GlobalStocktakes include comparisons between modeled and country-provided net land-use emissions.

Land remains a blind spot in tracking progress under the Paris Agreement due to lack of data comparability
Communications Earth & Environment - Discrepancies exist between data used in countries’ greenhouse gas inventories and modelled benchmarks for the Paris agreement, according to an...
What is the contribution of land use to countries' climate pledges?
🖋️ A new paper led by Rosa Roman-Cuesta explores this question and offers a way forward.
🌲 The study finds that land use makes up a quarter of global 2030 mitigation pledges — mostly reliant on external support.

This is relevant for forest-rich nations, where “natural” sinks often play a major role in net-zero pledges.
Policymakers need to grasp these implications and adjust their climate ambition accordingly

We also urge the scientific community to generate these inventory-aligned estimates and scenarios, and to explore the implications.
Key takeaways: under inventory definitions, the remaining carbon budget is smaller—and reaching net-zero CO₂ alone is not enough to stop warming.

Drawing on prior studies and IPCC Expert Meetings, the IPCC has recently decided that its 7th Assessment Report will present land-use CO₂ estimates and scenarios that align with national inventory definitions.
Our Comment explains why this is a crucial step forward.

These differing definitions are like two languages: each valid in its own context, but hard to compare without proper translation.
Reconciling them is key for aligning global models, national inventories, and Earth observation — ultimately building trust in land-use emission estimates.

Climate science and national reporting use different definitions for anthropogenic land-use CO₂ fluxes.
This disconnect has led to a 7 billion-tonne annual gap in CO₂ estimates from land use—equivalent to 20% of global fossil CO₂ emissions—causing confusion among scientists and policymakers

On 6–7 May 2025, a JRC-EEA workshop on Land Use Land-Use Change and Forestry (LULUCF) gathered in Ispra (IT) over 50 GHG inventory experts, scientists and policymakers.
We discussed challenges in GHG reporting and the decline of forest carbon sinks in Europe.

This is outrageous. Stupidity at work.
It’s a sign of ideological hostility to everything that involves a multilateral dialogue and cooperation.
If you ignore climate change, climate change will not ignore you.
