Nature Reviews Earth & Environment - Natural CO2 removal is increasingly being claimed as anthropogenic climate mitigation. This misrepresentation is already prevalent for forests and coastal...

La pêche industrielle réduit la capacité des océans à stocker le CO₂. Protéger la haute mer pourrait renforcer ce puits de carbone vital sans menacer la sécurité alimentaire.

Marine animals play a key role in locking carbon deep in the ocean, slowing climate change. This study finds that fishing has already cut this service in half, with climate change expected to further ...

‘Trumped-up’ charges spark diplomatic row as scientists express fears for health of 70-year-old Leonid Pshenichnov

The paper analyzes the impact of omitting biophysical effects from carbon credits on climate mitigation. It shows that some Voluntary Carbon Market projects may result in net warming due to albedo whi...

For decades, government subsidies have helped industrial fishing fleets to expand, often with little regard for sustainability.

A decade of BGC-Argo and plankton records shows North Pacific heatwaves reshape food webs and trap small particles in midwater, slowing deep-ocean carbon export. Impacts vary by event, underscoring the need for sustained ocean monitoring.

La majorité des aires marines protégées dans le monde n’offre que peu de protection face à la pêche industrielle, qui échappe souvent à toute surveillance publique.

The theory behind carbon offset projects is appealing: Instead of an organization cutting its own emissions, it can fund lower-cost carbon-reducing projects elsewhere to “offset” its emissions. The re...

Abstract. In a rapidly changing climate, evidence-based decision-making benefits from up-to-date and timely information. Here we compile monitoring datasets (published at https://doi.org/10.5281/zenodo.15639576; Smith et al., 2025a) to produce updated estimates for key indicators of the state of the climate system: net emissions of greenhouse gases and short-lived climate forcers, greenhouse gas concentrations, radiative forcing, the Earth's energy imbalance, surface temperature changes, warming attributed to human activities, the remaining carbon budget, and estimates of global temperature extremes. This year, we additionally include indicators for sea-level rise and land precipitation change. We follow methods as closely as possible to those used in the IPCC Sixth Assessment Report (AR6) Working Group One report. The indicators show that human activities are increasing the Earth's energy imbalance and driving faster sea-level rise compared to the AR6 assessment. For the 2015–2024 decade average, observed warming relative to 1850–1900 was 1.24 [1.11 to 1.35] °C, of which 1.22 [1.0 to 1.5] °C was human-induced. The 2024-observed best estimate of global surface temperature (1.52 °C) is well above the best estimate of human-caused warming (1.36 °C). However, the 2024 observed warming can still be regarded as a typical year, considering the human-induced warming level and the state of internal variability associated with the phase of El Niño and Atlantic variability. Human-induced warming has been increasing at a rate that is unprecedented in the instrumental record, reaching 0.27 [0.2–0.4] °C per decade over 2015–2024. This high rate of warming is caused by a combination of greenhouse gas emissions being at an all-time high of 53.6±5.2 Gt CO2e yr−1 over the last decade (2014–2023), as well as reductions in the strength of aerosol cooling. Despite this, there is evidence that the rate of increase in CO2 emissions over the last decade has slowed compared to the 2000s, and depending on societal choices, a continued series of these annual updates over the critical 2020s decade could track decreases or increases in the rate of the climatic changes presented here.
