A glance at the effects of climate change on grain cultivation in Iran and the world

In 2024, the amount of pollution produced by humans in the world has increased by 50%. Pollution that originates from machinery and industrial factories and other human activities. For about 28 years, we have seen a 50% increase in air pollution in the world, which has led to global warming. But with these problems, what has happened that the production of grains in the world has increased and reached almost 3 billion tons per year?!

It is worth mentioning that 50% of the increase in the earth’s heat has happened in the last 28 years, which is due to the countries of China and the United States as the two main economic engines that have increased the earth’s heat.

Wheat production in 2024 is much higher than in 1992, because the grain grows better in an atmosphere with more carbon dioxide, and ultimately the growing season is longer because the earth is warmer. Moreover, agricultural methods and the type of seed used have adapted to high heat.
