United Nations : "21 March 2017 – Rising temperatures could release massive amounts of carbon trapped in the Earth's soil, the United Nations agricultural agency today reported, warning that soil management could make or break climate change response efforts."While many are focused on reducing emissions, heat continues to be generated by human activity. Living uses energy, converting it to heat. The source does not matter, if activity grows, heat increases. This heat now threatens to release tons of carbon. That will make of mockery of attempts to reduce emissions.
