State of the climate in Asia 2023
Asia remained the world’s most disaster-hit region from weather, climate and water-related hazards in 2023. Floods and storms caused the highest number of reported casualties and economic losses, whilst

An unseen measurement bias has been identified in global records of sea surface temperature. The discrepancy will need correction, but will not affect conclusions about an overall warming trend.
The latest Red List of threatened species of birds by International Union for Conservation (IUCN) has established that climate change has "accelerated" factors that are putting many bird species under threat. This has resulted one in eight of the world's birds at risk of extinction. India is among the 10 countries whose bird species
Protected area systems and conservation corridors can help mitigate the impacts of climate change on Amazonian biodiversity. We propose conservation design criteria that will help species survive in situ or adjust range distributions in response to increased drought. The first priority is to protect the western Amazon, identified as the
Observations show that the standard precipitation index (SPI ) over the southern Amazon region decreased in the period of 1970
Interannual variations in CO2 exchange across Amazonia, as deduced from atmospheric inversions, correlate with El Nino occurrence. They are thought to result from changes in net ecosystemexchange and fire incidence that are both related to drought intensity. Alterations to net ecosystemproduction (NEP) are caused by changes in gross primary production (GPP) and ecosystemrespiration (Reco ).
The Amazon Basin experiences severe droughts that may become more common in the future. Little is known of the effects of such droughts on Amazon forest productivity and carbon allocation. We tested the prediction that severe drought decreases litterfall and wood production but potentially has multiple cancelling effects on belowground production within a 7-year partial throughfall exclusion experiment. We simulated an approximately 35
This paper uses a palaeoecological approach to examine the impact of drier climatic conditions of the Early
Using a mixture of observations and climate model outputs and a simple parametrization of leaf-level photosynthesis incorporating known temperature sensitivities, we find no evidence for tropical forests currently existing
This paper argues for a twofold perspective on human adaptation to climate change in the Amazon. First, we need to understand the processes that mediate perceptions of environmental change and the behavioural responses at the levels of the individual and the local population. Second, we should take into account the process of production and dissemination of global and national climate information and models to regional and local populations, especially small farmers.
