The increasing concentration level of atmospheric CO2, which is a major factor of climate change, has to be considered for the consequences of climate change on agriculture because CO2 is involved in the key processes for plants, such as photosynthesis. Irregular cropping is the biggest problem in mango production. Inconsistent run of cool nights and relatively warm winter has adversely affected flowering in mango. Increases in extreme mean temperatures are already affecting mango production. So, rapid climate change should be a great concern irrespective of mango growers, scientists and buyers. The large diversity in genetic resources of mango is a boon for selection and breeding programs to face climatic changes. To fight against this climate change some strategies could be taken like substitution and complementation of low temperature by using growth retardant (PB Z) along with imposition of moisture stress (-75 kpa or even less) for about 4 months prior to flowering, post-harvest thinning of large branches of vigorous and late varieties grown in heavy soils to encourage soil moisture loss during winter months, digging trenches along the drip line for better drainage during monsoon and ensuring moisture stress condition during winter months, encouraging new mango plantation in light and sandy loam soils which has the capacity to loss moisture quickly, shoot pruning after harvest (impracticable for tall growing trees) to encourage more new shoots which become mature (8-9 months) at the time of flowering followed by nutrients and irrigation.
