The impacts of climate change on tropical and subtropical horticultural production por Mathur, P.N., Ramírez Villegas, Julián Armando, Jarvis, Andy

“…Nobel Prize winner, the Intergovernmental Panel on Climate Change (IPCC) by means of the four assessment reports that have been released to date (IPCC 1990, 1995, 2001, 2007), has shown scientific evidence that i) temperatures have been increasing during the second half of the 20th century, and that ii) these changes are driven to a considerable extent by increases in the concentration of greenhouse gases (GHGs) in the atmosphere. …”

The FAOSTAT database of greenhouse gas emissions from agriculture por Tubiello, F.N., Salvatore, M., Rossi, S, Ferrara, A., Fitton N, Smith, Pete

“…Greenhouse gas (GHG) emissions from agriculture, including crop and livestock production, forestry and associated land use changes, are responsible for a significant fraction of anthropogenic emissions, up to 30% according to the Intergovernmental Panel on Climate Change (IPCC). Yet while emissions from fossil fuels are updated yearly and by multiple sources—including national-level statistics from the International Energy Agency (IEA)—no comparable efforts for reporting global statistics for agriculture, forestry and other land use (AFOLU) emissions exist: the latest complete assessment was the 2007 IPCC report, based on 2005 emission data. …”
