Short summary
Striking differences exist in estimates of land-use CO2 fluxes between the national greenhouse gas inventories and the IPCC assessment reports. These differences hamper an accurate assessment of the collective progress under the Paris Agreement. By implementing an approach that conceptually reconciles land-use CO2 flux from national inventories and the global models used by the IPCC, our study is an important step forward for increasing confidence in land-use CO2 flux estimates.

The Global Carbon Budget 2022 describes the datasets and methodology used to quantify the anthropogenic emissions of carbon dioxide (CO2) and their partitioning among the atmosphere, the land ecosystems, and the ocean. These living datasets are updated every year to provide the highest transparency and traceability in the reporting of CO2, the key driver of climate change.

To become carbon neutral by 2050, the European Union (EU27) forest C sink should increase to −450 Mt CO2 yr-1. Our study highlights that under current management practices (i.e. excluding any policy scenario) the forest C sink of the EU27 member states and the UK may decrease to about −250 Mt CO2eq yr-1 in 2050. The expected impacts of future climate change, however, add a considerable uncertainty, potentially nearly doubling or halving the sink associated with forest management.

Cette étude consiste en la prévision des pluies dans le bassin côtier oranais en Algérie d'ici la fin du 21ème siècle, issues des modèles climatiques régionaux. D’une manière générale, les résultats de simulations ont mis en évidence une réduction de −15 % à −40 % des pluies. cette recherche est une contribution pour la mise en place d’un outil d’aide à la planification et l’élaboration d’un plan d’actions opérationnel pour la gestion durable des ressources en eau dans le secteur d’étude.

Le taux de sédimentation des barrages du bassin hydrographique du Cheliff reste le plus élevé de toutes les régions de l’Algérie. L’oued Mina est un affluent majeur de l’oued Cheliff, le plus grand oued de l’Algérie qui transporte un taux de sédiment important et le barrage de Sidi M’Hamed Ben Aouda (Relizane) qui barre cet oued a reçu un volume de vase égal à 6,7 millions de m3 par année.

The downward of rainfall trend occurred in the study area in 1972, affecting a few coastal stations. In 1976, this decline extended to the South West and throughout the coastal region. In 1980, the drop covered the entire basin. This decline has resulted in an estimated deficit of 30 % on average in the eastern region, the coastal region and the Mina. However, the central part of the basin experienced a 20 % decrease compared to the period before the break (1968–1980).

The amount of solar energy absorbed by Earth is believed to strongly depend on clouds. Here, we investigate this relationship using satellite data and 32 climate models, showing that this relationship holds everywhere except over polar seas, where an increased reflection by clouds corresponds to an increase in absorbed solar radiation at the surface. This interplay between clouds and sea ice reduces by half the increase of net radiation at the surface that follows the sea ice retreat.

The winter snow insulation is a key process for air–soil temperature coupling and is relevant for permafrost simulations. Differences in simulated air–soil temperature relationships and their modulation by climate conditions are found to be related to the snow model physics. Generally, models with better performance apply multilayer snow schemes.

Soil temperature change is a key indicator of the dynamics of permafrost. Using nine process-based ecosystem models with permafrost processes, a large spread of soil temperature trends across the models. Air temperature and longwave downward radiation are the main drivers of soil temperature trends. Based on an emerging observation constraint method, the total boreal near-surface permafrost area decrease comprised between 39 ± 14 × 103 and 75 ± 14 × 103 km2 yr−1 from 1960 to 2000.

Short summary
The temporal evolution of drought events characteristics is discussed.
Data from observations and simulations of the regional climate model RCA4 MPI-ESM-LR under two Representative Concentration Pathways (RCPs) scenarios for the period (1941–2100) are used. An amplification of drought frequencies is projected in the future under the RCP8.5 scenario. The maximum duration is expected to hardly change under the RCP8.5 scenario or even to decline.
The temporal evolution of drought events characteristics is discussed.
