Climate change

Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider effects on Earth's climate system. Climate change in a broader sense also inclu

Sea ice reflects 50% to 70% of incoming sunlight, while the ocean, being darker, reflects only 6%. As an area of sea ice melts and exposes more ocean, more heat is absorbed by the ocean, raising temperatures that melt still more ice. This is a positive feedback process.

Effects of climate change on agriculture

There are numerous effects of climate change on agriculture, many of which are making it harder for agricultural activities to provide global food security. Recent research has found that climate chan

Soybean plants grow less and develop a smaller leaf area as they are exposed to temperatures beyond what they are historically used to.

Future warming is expected to consistently increase the strength of heavy rainfall, yet it also consistently increases the amount of water plants lose through evapotranspiration. This effect is counteracted by the CO2 fertilization effect, but at times not enough to avoid events like the 2020–2023 Horn of Africa drought.

Average decrease of micronutrient density across a range of crops at elevated CO2 concentrations, reconstructed from multiple studies through a meta-analysis. The elevated concentration in this figure, 689 ppm, is over 50% greater than the current levels, yet it is expected to be approached under the "mid-range" climate change scenarios, and will be surpassed in the high-emission one.
