Question

list six effects of climate change that has negative influence on food production ​

Answer 1

Explanation:

There is considerable uncertainty, and impacts depend on the interplay between:

Gradual temperature increase.

The CO2 fertilisation effect (whereby higher ambient CO2 concentrations in the atmosphere can stimulate increased plant growth and boost productivity, although the strength of this effect is unclear).

Extreme events such as drought and flooding; temperature peaks.

Water.

Economics, demographics, infrastructure.

Impacts will also depend on the degree of climatic change – i.e. it will vary between a 2°C and 1.5°C temperature increase. Scenarios, largely based on models, are used to provide plausible predictions and reduce uncertainty.

Impacts on agriculture and food security are uncertain, and depend on the interplay between many physical factors such as temperature, CO₂ levels, precipitation and extreme events, as well as social, demographic and economic factors, that influence people’s ability to adapt to change and may also have an affect on future emissions.
