Global climate change and human health: Pathways and possible solutions

Eco-Environment & Health, Год журнала: 2022, Номер 1(2), С. 53 - 62

Опубликована: Май 7, 2022

Global warming has been changing the planet's climate pattern, leading to increasing frequency, intensity and duration of extreme weather events natural disasters. These climate-changing affect various health outcomes adversely through complicated pathways. This paper reviews main signs change so far, e.g., suboptimal ambient temperature, sea-level rise other conditions, depicts interactive pathways between different such as wildfires, floods with a broad range outcomes. Meanwhile, modifying effect socioeconomic, demographic environmental factors on is summarised, that youth, elderly, females, poor those living in coastal regions are particularly susceptible change. Although Earth whole expected suffer from change, this review article discusses some potential benefits for certain regions, more liveable environment sufficient food supply. Finally, we summarise mitigation adaptation strategies against how these may benefit human ways. provides comprehensive concise introduction possible solutions, which map directions future research.

Actions to halt biodiversity loss generally benefit the climate

The two most urgent and interlinked environmental challenges humanity faces are climate change biodiversity loss. We entering a pivotal decade for both the international agendas with sharpening of ambitious strategies targets by Convention on Biological Diversity United Nations Framework Climate Change.

Shift in algal blooms from micro‐ to macroalgae around China with increasing eutrophication and climate change

Global Change Biology, Год журнала: 2023, Номер 30(1)

Опубликована: Ноя. 8, 2023

Abstract Blooms of microalgal red tides and macroalgae (e.g., green golden caused by Ulva Sargassum ) have widespread problems around China in recent years, but there is uncertainty what triggers these blooms how they interact. Here, we use 30 years monitoring data to help answer questions, focusing on the four main species microalgae Prorocentrum donghaiense , Karenia mikimotoi Noctiluca scintillans Skeletonema costatum associated with region. The frequency increased from 1991 2003 then decreased until 2020, S. exhibiting highest rate decrease. Green started occur 1999 has since been increase. Golden were first reported 2012. macroalgal a negative linear relationship coverage China, positive correlation total nitrogen phosphorus loads as well atmospheric CO 2 sea surface temperature (SST). Increased outbreaks are very likely due worsening levels eutrophication, combined rising SST, which contribute reduced tides. increasing grazing microzooplankton also results decline areas affected This study shows clear shift algal over past driven combination climate change, stress, indicating fundamental change coastal systems

Harmful Algal Blooms in Chinese Coastal Waters Will Persist Due to Perturbed Nutrient Ratios

Environmental Science & Technology Letters, Год журнала: 2021, Номер 8(3), С. 276 - 284

Опубликована: Янв. 22, 2021

The three large marine ecosystems (LMEs) bordering China (Yellow Sea/Bohai Sea, East and South Sea) have received excess nitrogen (N) phosphorus (P) in the past decades with detrimental consequences for ecosystem functioning, such as increased productivity, loss of biodiversity, proliferation harmful algal blooms (HABs). N loading much faster than that P. Here, we show HABs LMEs started to proliferate after N:P molar ratio exceeded threshold value 25 1980s. mismatch P inputs is not only related differences loads but also inherent their biogeochemical cycles which more efficiently filter land- waterscapes. Future Shared Socioeconomic Pathways high ratios will persist come, even worsening a future oriented toward sustainability, indicate may be persisting problem China's coastal waters. While efforts agricultural systems are governed by agronomic crop requirements easy manage respect ratios, separate collection urine urban rural areas could contribute decreases both total nutrient ratios.

Stocks and losses of soil organic carbon from Chinese vegetated coastal habitats

Global Change Biology, Год журнала: 2020, Номер 27(1), С. 202 - 214

Опубликована: Сен. 25, 2020

Abstract Global vegetated coastal habitats (VCHs) represent a large sink for organic carbon (OC) stored within their soils. The regional patterns and causes of spatial variation, however, remain uncertain. sparsity bias studies on soil OC stocks from Chinese VCHs have limited the reliable estimation capacity as global sinks. Here, we use field published data 262 sampled cores 181 surface soils to report estimates stocks, burial rates losses in China. We find that mangrove, salt marsh seagrass relatively low storing 6.3 ± 0.6, 7.5 1.6 0.6 Tg C (±95% confidence interval) top meter profile with 44 17, 159 57, 6 45 Gg C/year, respectively. variability is linked biogeographic factors but mostly impacted by sedimentary processes anthropic activities. All experienced significant losses, resulting estimated emissions 94.2–395.4 CO 2 e (carbon dioxide equivalent) over past 70 years. Reversing this trend through conservation restoration measures has, therefore, great potential contributing mitigation climate change while providing additional benefits. This assessment, national scale highly environments under intensive anthropogenic pressures, provides important insights into blue mechanism sequestration capacities, thus synchronous progression management.
