This article mentions the lack of rainfall and how the warming of areas in South Asia and Africa will have harmful effects on crop growth such as corn, wheat, soybean and sugar cane. Most of these crops are used heavily in these countries and could be detrimental to their economy. The predictions say growth may drop up to 30% for corn, which is enormous.
I actually had the opportunity to go to India this past winter break and noticed that the weather was quite warm. It was in the low 70's during the day and high 50's in the evening. My grandmother told me she had never once experienced a winter like this in Delhi. In the past, when I have gone to visit, it was always very cold and you would have to wear layers of clothes just to stay warm. I think this shows the impact of global warming today and not just for the future. Although, the article predicts changes in crop growth for the year 2030, I believe it will happen sooner than that.
It is also sad that a place like Southern Africa is being affected more by global warming in certain aspects than countries like China and the US.
