The world’s best science concludes that our climate is changing through human activities that release CO2 and other greenhouse gases to the atmosphere. Farming, forestry, and livestock production emit nearly one third of the global total.
These emissions are likely to increase as farmers and livestock producers around the world race to keep up with growth in demand.
Good soil management could absorb 10% of the world’s CO2 emissions.
The world has seen an increase of atmospheric CO2 concentration (278ppm in 1750 vs 390.5ppm in 2011).
The IPCC estimates that the world’s oceans have absorbed about 30% of human CO2 emissions.
In the near term, climate change means more extreme weather; extreme droughts, floods, and temperature extremes may exacerbate increasing land and food security challenges by restricting global production of food, fiber, fuel, and feed. The poor will be the hardest hit by climate change. Land use could also become a solution to climate change.If humanity succeeds in slowing then reversing tropical deforestation and forest degradation, managing agricultural systems and grazing lands to accumulate more organic matter in the soil, and reducing the emissions associated with crop and livestock production, then land use could remove more CO2 from the atmosphere then it releases. The decline in deforestation in the Brazilian Amazon demonstrates that rapid reductions in global emissions are feasible.
