What is WWF doing about climate?

Why does farming cause global warming?
Dominant sources of agricultural greenhouse gases (GHGs) include carbon dioxide (CO2) from tropical deforestation, methane (CH4) from livestock and rice production, and nitrous oxide (N2O) from fertilizing or burning croplands. Agriculture is responsible for about half of global methane emissions.
How does deforestation cause global warming?
When forests are cut down, much of that stored carbon is released into the atmosphere again as CO2. This is how deforestation and forest degradation contribute to global warming. The consensus among climate scientists is that CO2 from tropical deforestation now makes up less than 10 percent of global warming pollution.
How is farming causing global warming?
Agriculture and forestry together are estimated to account for 10.5 percent of U.S. greenhouse gas emissions in 2018, including carbon dioxide emissions associated with agricultural electricity consumption. Globally, carbon dioxide emissions are the largest contributor to climate change.
What is climate change BBC UK?
Climate is the average weather in a place over many years. Climate change is a shift in those average conditions. The rapid climate change we are now seeing is caused by humans using oil, gas and coal for their homes, factories and transport.
