Through photosynthesis, plants use CO 2 from the atmosphere, water from the ground, and energy from the sun to create sugars used for growth and fuel. [22] While using these sugars as fuel releases carbon back into the atmosphere (photorespiration), growth stores carbon in the physical structures of the plant (i.e. leaves, wood, or non-woody stems).

Climate change is known to increase the frequency and severity of heatwaves, and to make precipitation less predictable and more prone to extremes, but since climate change attribution is still a relatively new field, connecting specific weather events and the shortfalls they cause to climate change over natural variability is often difficult.
[5] [6] Furthermore, there is also fossil fuel consumption for transport and fertilizer production. For example, the manufacture and use of nitrogen fertilizer contributes around 5% of all global greenhouse gas emissions. [7] Livestock farming is a major source of greenhouse gas emissions. [8] At the same time, livestock farming is affected by ...
A fertilizer (American English) or fertiliser (British English) is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. [1]
Kenya's government first introduced a fertilizer subsidy in 2008, making chemical fertilizers more accessible for smaller-scale farmers. ... climate change and other issues that have increased ...
Air pollution caused by agriculture through land use changes and animal agriculture practices have an outsized impact on climate change. Addressing these concerns was a central part of the IPCC Special Report on Climate Change and Land [48] as well as in the 2024 UNEP Actions on Air Quality report. [49]
A related phenomenon driven by climate change is woody plant encroachment, affecting up to 500 million hectares globally. [218] Climate change has contributed to the expansion of drier climate zones, such as the expansion of deserts in the subtropics. [219] The size and speed of global warming is making abrupt changes in ecosystems more likely ...
This contributes to climate change. Carbon dioxide (CO 2), from burning fossil fuels such as coal, oil, and natural gas, is the main cause of climate change. The largest annual emissions are from China followed by the United States. The United States has higher emissions per capita.
