Animal-derived food plays a larger role in meeting human protein needs, yet is still a minority of supply at 39%, with crops providing the rest. [79]: 746–747 Out of the Shared Socioeconomic Pathways used by the Intergovernmental Panel on Climate Change, only SSP1 offers any realistic possibility of meeting the 1.5 °C (2.7 °F) target. [80]
A recent study testing the effects of Bt corn pollen dusting nearby milkweed plants on larval feeding of the monarch butterfly found that the threat to populations of the monarch was low. [12] The use of GMO crop plants engineered for herbicide resistance can also indirectly increase the amount of agricultural pollution associated with ...
There are numerous effects of climate change on agriculture, many of which are making it harder for agricultural activities to provide global food security.Rising temperatures and changing weather patterns often result in lower crop yields due to water scarcity caused by drought, heat waves and flooding.

The claim: Climate change has only had 'positive effects' on global food production. An Oct. 20 Facebook post (direct link, archive link) includes a graph that shows global wheat, rice and coarse ...
Management techniques range from animal management and housing to the spread of pesticides and fertilizers in global agricultural practices, which can have major environmental impacts. Bad management practices include poorly managed animal feeding operations, overgrazing, plowing, fertilizer, and improper, excessive, or badly timed use of ...

[27]: 746–747 Out of the Shared Socioeconomic Pathways used by the Intergovernmental Panel on Climate Change, only SSP1 offers any realistic possibility of meeting the 1.5 °C (2.7 °F) target. [28]
This level of heat would not have been possible without human-caused climate change, according to the WWA. Such temperature spikes will become more common in many places as the world continues to ...
Abiotic stress mostly affects plants used in agriculture. Some examples of adverse conditions (which may be caused by climate change) are high or low temperatures, drought, salinity, and toxins. [20] Rice (Oryza sativa) is a classic example. Rice is a staple food throughout the world, especially in China and India.
