AI Article Synopsis
- The study aimed to synthesize findings from systematic reviews on the health impacts of climate change, focusing on study characteristics, climate effects, and health outcomes.
- Researchers conducted a thorough overview, including a comprehensive literature search and organizing results based on geographical regions and health outcomes, assessing the quality of the studies involved.
- Out of 94 reviews, most indicated that climate change negatively affects human health, particularly in areas like infectious diseases and extreme weather-related health issues, while highlighting the need for further research.
Article Abstract
Objectives: We aimed to develop a systematic synthesis of systematic reviews of health impacts of climate change, by synthesising studies' characteristics, climate impacts, health outcomes and key findings.
Design: We conducted an overview of systematic reviews of health impacts of climate change. We registered our review in PROSPERO (CRD42019145972). No ethical approval was required since we used secondary data. Additional data are not available.
Data Sources: On 22 June 2019, we searched Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, Cochrane and Web of Science.
Eligibility Criteria: We included systematic reviews that explored at least one health impact of climate change.
Data Extraction And Synthesis: We organised systematic reviews according to their key characteristics, including geographical regions, year of publication and authors' affiliations. We mapped the climate effects and health outcomes being studied and synthesised major findings. We used a modified version of A MeaSurement Tool to Assess systematic Reviews-2 (AMSTAR-2) to assess the quality of studies.
Results: We included 94 systematic reviews. Most were published after 2015 and approximately one-fifth contained meta-analyses. Reviews synthesised evidence about five categories of climate impacts; the two most common were meteorological and extreme weather events. Reviews covered 10 health outcome categories; the 3 most common were (1) infectious diseases, (2) mortality and (3) respiratory, cardiovascular or neurological outcomes. Most reviews suggested a deleterious impact of climate change on multiple adverse health outcomes, although the majority also called for more research.
Conclusions: Most systematic reviews suggest that climate change is associated with worse human health. This study provides a comprehensive higher order summary of research on health impacts of climate change. Study limitations include possible missed relevant reviews, no meta-meta-analyses, and no assessment of overlap. Future research could explore the potential explanations between these associations to propose adaptation and mitigation strategies and could include broader sociopsychological health impacts of climate change.

Efficient Direct Air Capture in Industrial Cooling Towers Mediated by Electrochemical CO2 Release.
Angew Chem Int Ed Engl
December 2024
Shandong University, Environment Research Institute, Binhai Road 72, 266237, Qingdao, CHINA.
Direct air capture (DAC) is a promising technology for mitigating global climate change but suffers from low efficiency, small scale, and high cost due to the dilute atmospheric CO2, limited size of air contactors, and heat-driven CO2 release. Here, we propose combining DAC with widely used industrial cooling towers to extract CO2 from the air and using electrolysis to release the captured CO2 at room temperature. We first prepare a buffered absorbent solution consisting of sodium glycinate, glycine, and sodium chloride for effective CO2 capture from the air, solving the incompatibility problem of the cooling towers with conventional absorbents.

Governance and resource allocation are challenged by movements such as decolonizing global health. Inherent contradictions within global health derive from its historical evolution from tropical medicine and international health, as well as recent trends in infectious diseases.

Sarawak Tropical Peat Research Institute, Kota Samarahan, Sarawak, Malaysia.
Tropical peatlands significantly influence local and global carbon and nitrogen cycles, yet they face growing pressure from anthropogenic activities. Land use changes, such as peatland forests conversion to oil palm plantations, affect the soil microbiome and greenhouse gas (GHG) emissions. However, the temporal dynamics of microbial community changes and their role as GHG indicators are not well understood.

Phosphorus is an essential component of numerous macromolecules and is vital for life. Its availability significantly influences primary production, particularly in oligotrophic environments. Marine diazotrophic cyanobacteria, which play key roles in biogeochemical cycles through nitrogen fixation (N fixation), have adapted to thrive in phosphate (P)-poor areas.
