ABSTRACT
Global warming is a phenomenon of climate change characterized by a general increase in average temperatures of the Earth, which modifies the weather balances and ecosystems for a long time. Climate change has emerged as the most pressing global challenge of the 21st century and which is one of the largest and most complex problems, the developed community has ever faced. Climate change will increase the risk of simultaneous crop failures across the world's biggest corn-growing regions and lead to less of the nutritionally critical vegetables that health experts say people aren't getting enough of already, scientists warn. Extreme weather events have caught attention of agrarian experts and scientists alike and they are now focusing on natural farming to arrest the impacts of climate change. Rising temperature affects flowering and leads to pests and disease buildup. Flood and excess rain over a short duration of time cause extensive damage to crops.
