The ongoing climate change crisis presents the most serious environmental challenge to global plant ecosystems, as it threatens both species diversity and their natural geographic ranges. This research study examines how climate change affects the geographical distribution of plant species together with their respective habitats by studying three main climatic changes which include rising temperatures and altered rainfall patterns and increasing atmospheric carbon dioxide concentrations. The study results show that changes in weather conditions lead to alterations in plant development and breeding mechanisms and survival rates which in turn result to changes in species abundance and ecosystem health.The research team used fieldwork to gather primary data while they obtained secondary data from established research materials. The study found that rising temperatures force plant species to shift their range toward higher mountain peaks and northern regions while endangered species face extinction threats because of their declining habitats and rising environmental pressures. Invasive species present a dual danger to native biodiversity because they spread to new areas while climate change enables them to infiltrate new environments. The research shows that climate change causes plants to shift their native range which results in harmful effects on both natural ecosystems and agricultural systems. The research shows that immediate conservation actions together with environmentally friendly policies and public education initiatives should protect plant diversity.
