Impact of changing climate on Global Biodiversity

Abstract

Climate change has accelerated biodiversity loss by gradually altering ecosystem structures, endangering the survival and integrity of numerous species due to changes in optimal temperature ranges. Among the effects of climate change are severe droughts, water scarcity, fires, flooding, rising sea levels, melting polar ice, devastating storms, and decline in biodiversity. Biodiversity and ecosystems are at serious risk due to the long-term effects of climate change which are mostly caused by human activities. Sea level rise is endangering coastal communities, and biodiversity is under tremendous strain as ecosystems find it difficult to adjust to the quickly changing environment, leading to habitat loss and the extinction of species. As the average global temperature rises, extreme weather events such as hurricanes, floods, cloudbursts and droughts are becoming more severe and frequent; climate models are based on records of the kinds of weather that have occurred under comparable patterns, as well as on global patterns in the ocean and atmosphere. Recently, Dharali in Uttarakhand, Kistwar in Himachal Pradesh and Kathua in Jammu and Kashmir have been severely affected through cloudburst in Himalayan range. Agriculture faces serious challenges due to temperature and precipitation variations brought on by climate change like heat stress is increased by rising temperatures, which interferes with pollination and reduces staple crop yields. Extreme heat and unpredictable rainfall deteriorate soil health by reducing organic matter and vital nutrients, while irregular monsoon patterns and decreased rainfall cause severe droughts and flash floods. Furthermore, the prevalence of heat-related illnesses and the spread of vector-borne diseases are increasing worldwide. Extreme weather events, air quality, water resources, infrastructure, energy demands, socio economic inequality, and the urban heat island effect are some of the main effects of climate change on urban climates.
