As análises a respeito de mudanças climáticas, ou do impacto dessas sobre cultivos específicos, como de arroz, não devem se ater somente pelo volume de precipitação das águas de chuvas ou da variação da temperatura. Devem ser avaliados todos os fatores climáticos locais e não locais, pois que a Natureza não é impactada localmente devido a ocorrências locais. A interação do clima e temperatura é completa e abrange todo o planeta. Poluições causadas em locais distantes podem afetar culturas de grãos e cereais localmente. A Diretiva de Seveso foi importante para a Europa. A respeito deste tema sugiro a leitura de artigo que publiquei através da Editora Roncarati, R. Bras. Risco e Seg., Rio de Janeiro, v. 5, n. 10, p. 103-140, out. 2009/mar. 2010, com o título: Industrial accidents and their consequences

Antonio Fernando de A. Navarro Pereira, Civil Engineer, specialist in Risk. Management, Masters Degree in Health and Environment at Universidade

da Região de Joinville (Univille), quando digo:

This article addresses the relationship between major accidents in industrial activities involving oil and gas industries, through different perspectives, and their consequences on the environment. It also tackles the question of their recurrence and the impact caused on the issues related to socio-environmental sustainability. Finally, it analyzes the relevant legislation and what it can do to reduce accidents, if and when it is correctly applied, specially the Seveso Directive (Directive 82/501/EEC) and the Convention 174 from ILO (International Labor Organization).

The effects of such accidents over human life are not discussed here and the process failures that may have led to the occurrence of accidents are not analyzed either, because it is well known that the subject requires a more in-depth analysis and one accident may differ from another. Here, accidents are generalized, considering them simply as "accidents".

Due to the fact that there is a wide range of activities involving industrial accidents, this article sought to include those which have the greatest potential to cause harm to the environment, especially the industries that work with hydrocarbons and its derivatives, with particular attention to an accident that caused great international impact and which occurred near the city of Bhopal in the area of Central India.

This paper shall analyze, in a summarized manner, the accident in Bhopal and the consequences that this event brought to the world, not to mention the resulting revision of the literature about the subject and the Safety Guidelines, such as the one which received the name of Seveso Directive in honor of the Italian city that was "victim" to a major industrial accident, as well as the Proceedings of the International Labor Organization (ILO).

Rf and temp. are  not enough but it is sufficient for explaining main independent parameter influences on rice growth, development   and yield. 

That is a good question and I think it could be an interesting experiment if you would pursue this further. Humidity is a function of temperature and rainfall, but it is not the same thing as measuring its actual impact in an experiment, including wind impact, because humidity is affected by the wind too. Just be clear about the wind's humidity (or temperature and direction) too. Best regards.

 I agree with what Maria Alexou features in the comments. I believe there are many aspects to the issue of planting, mainly in areas of terraces, for rice planting. Certain is that contrary to what you think Trump, global warming and the specific climate changes could compromise future generations. An alternative that can be taken is the use of other seeds, more resistant to temperature, and greater attention to water temperature and acidity of the soil/water.

Rainfall,temperature and solar radiation are the main driving variables of the soil-plant-atmosphere exchanges.

You that is OK.

DR.  Yes, This ok
