2. INTRODUCTION Climate change is a pervasive and growing global threat to biodiversity and ecosystems. The rapid urbanization of world or India has also resulted in significant changes to people’s lifestyles. climate change refers to significant and lasting changes in the Earth's climate patterns over a long period of time, typically decades to millions of years. These changes are primarily driven by human activities, particularly the emission of greenhouse gases such as carbon dioxide, methane, and nitrous oxide, which trap heat in the Earth's atmosphere and lead to global warming. The primary causes of climate change include the burning of fossil fuels for energy, deforestation, industrial processes, and agricultural practices. These activities release large amounts of greenhouse gases into the atmosphere, enhancing the natural greenhouse effect and causing the Earth's average temperature to rise.

3. CONSEQUENCES OF CLIMATE CHANGE Rising global temperatures: Average temperatures around the world have been increasing, leading to more frequent and intense heatwaves. Melting ice caps and glaciers: The warming climate has caused ice caps and glaciers in polar regions to melt at an accelerated rate, contributing to rising sea levels. Ocean acidification: The absorption of excess CO2 by the oceans leads to increased acidity, which can harm marine life, particularly organisms with calcium carbonate shells, such as corals and shellfish. Extreme weather events: Climate change is linked to an increase in the frequency and intensity of extreme weather events, such as hurricanes, droughts, floods, and wildfires. Disruption of ecosystems: Changes in temperature and precipitation patterns can disrupt ecosystems, leading to shifts in habitats, loss of biodiversity, and threats to food security.

AUTHOR JOURNAL TITLE OBSERVATION 1 FengSheng Chien , Ka Yin Chau , Muhammad Sadiq a ELSeVIER (2023) Impact of climate mitigation technology and natural resource management on climate change in China The aim of this article is to check the extent to which RE output, RE consumption, natural resource rents, and natural resource depletion, along with industrialization and economic growth, can be effective in mitigating climate change 2 JamesVose Jake F. Weltzin Michelle D. Staudinger Elsevier Climate change effects on biodiversity, ecosystems, ecosystem services, and natural resource management in the United States U.S. Climate impacts have been and will continue to be observed at the level of individuals, popuiations , and species through changes in behaviour and morphology, and at the ecosystem level through changes in primary production, species interactions. Ecosystems and biodiversity underpin important services to people, thus these changes impact provisioning, regulating, supporting, with implications for human

Krol , Axel Bronstert Elsevier (2007) Regional integrated modelling of climate change impacts on natural resources and resource usage in semi-arid Northeast Brazil This indicates that the sustainability of regional development along a business-as-usual pathway may critically depend on the regional materialisation of climate change. The model was also successful in exploring potential impacts of climate change and other global change processes on crop yield and agricultural production, making evident that water is a crucial factor. 4 Rattan Lal National Academy of Agricultural Sciences (2012) Climate Change and Soil Degradation Mitigation by Sustainable Management of Soils and Other Natural Resources There exists a close link between soil erosion or degradation, climate change, and poverty. Soil degradation creates a positive feedback attributed to emission of radiatively active gases depletion of soil organic carbon and denudation of vegetation cover, and reduction in net primary productivity, increase in intensity of droughts loss of ecosystem resilience.
