Climate change further poses a challenge to food security challenges with its influence on food production, costs, and security. Excessive heat or shortage of water can impede crop growth; reduce yields, and influence irrigation, soil quality, and the ecosystem on which agriculture depends. Climate change is one of the main drivers of biodiversity loss, but destruction of ecosystems undermines nature's ability to regulate greenhouse gas (GHG) emissions and protect against extreme weather, thus accelerating climate change and increasing vulnerability to it. The major impacts on biodiversity and ecosystems are loss of habitat due to encroachment of forest areas, expansion of agriculture and settlement in forest area, development of infrastructure within the forest area, planned priority projects within forestland to uplift economic development.

The risk of species extinction increases with every degree of warming. In the ocean, rising temperatures increase the risk of irreversible loss of marine and coastal ecosystems. Live coral reefs, for instance, have nearly halved in the past 150 years, and further warming threatens to destroy almost all remaining reefs. Working with nature to conserve, manage and restore ecosystems known as nature-based solutions is one of the most cost-effective approaches to both mitigating and adapting to climate change. Climatic changes could also have positive effects on biodiversity. For instance, more clement temperatures and increased CO2 are likely to be beneficial to many plants, resulting in an acceleration of biomass production. Milder winters might increase survival of many currently threatened species in temperate regions. Rising temperatures are likely to result in widespread ecological change. Many animal and plant species are likely to become extinct as ecosystems adjust to climate change. While adaptable species will survive, and other migrate, the end result will be lost biodiversity. Impacts of climate change on ecosystems reduce their ability to improve water quality and regulate water flows. Rapid changes to ecosystems may cause the displacement or loss of many species. Climate change further poses a challenge to food security challenges with its influence on food production, costs, and security. Excessive heat or shortage of water can impede crop growth; reduce yields, and influence irrigation, soil quality, and the ecosystem on which agriculture depends. Climate change affects food production, and thus food availability. Climate change will impact the livelihoods and income of small-scale food producers and also, through food price increases and volatility, the livelihoods of poor net food buyers, restricting access to food.Extreme weather is a driver of world hunger. As global temperatures and sea levels rise, the result is more heat waves, droughts, floods, cyclones and wildfires. Those conditions make it difficult for farmers to grow food and for the hungry to get it.

The monsoon has a significant impact on Indian agriculture. In many areas of India, a lack of groundwater can be a serious threat to agriculture, particularly in areas that are prone to drought, such as western India and the Deccan plateau, when the monsoon fails. Floods frequently occur in the Gangetic plains and Assam, causing severe food shortages. Cyclones frequently impact the Arabian Sea and Bay of Bengal coasts, and residents suffer from severe food shortages. Climate change can affect all four dimensions of food security: food production, food availability, food accessibility, food utilization and food systems stability.

A major impact of climate change on biodiversity is the increase in the intensity and frequency of fires, storms or periods of drought.Climate change has altered marine, terrestrial, and freshwater ecosystems around the world. It has caused the loss of local species, increased diseases, and driven mass mortality of plants and animals, resulting in the first climate-driven extinctions.

Climatic changes could also have positive effects on biodiversity. For instance, more clement temperatures and increased CO2 are likely to be beneficial to many plants, resulting in an acceleration of biomass production. Milder winters might increase survival of many currently threatened species in temperate regions. The chief benefits of global warming include: fewer winter deaths; lower energy costs; better agricultural yields; probably fewer droughts; maybe richer biodiversity. Symptoms of climate change are all around us: extreme weather, diminishing sea ice, year after year of record-breaking warmth, drought, fires, and stress to ecosystems. The ocean level is rising, glaciers are melting, CO2 in the air is increasing, forest and wildlife are declining, and water life is also getting disturbed due to climatic changes. Apart from that, it is calculated that if this change keeps on going then many species of plants and animals will get extinct. Consequences of climate change on the species component of biodiversity include: changes in distribution, increased extinction rates, changes in reproduction timings, and changes in length of growing seasons for plants.
