‘Global warming’ is defined by the International Panel for Climate Change (IPCC) as an increase in combined air and sea surface temperatures averaged over the globe over 30 years. Earth’s temperature is believed to have risen by 0.08° C per decade since 1880. Global warming reached about 1°C by 2020.
Land use change refers to the change in function of an area of land. Since the 1960s, demand for food has resulted in an unprecedented rate of land use change. Land conversion for agriculture is a key driver of the current climate emergency.
This article explores the findings of the IPCC Assessment Report 5. Global warming and increase in GHG emissions are at their highest levels yet; the report concludes that significantly more action needs to be taken or temperatures will rise to 4 degrees above pre-industrial levels by the end of the century.
