Humans have rapidly changed our Earth's climate, well beyond the natural variations recorded over at least the last million years. This perturbation has reached the point where other parts of the natural system are poised to change their behavior through accelerating feedbacks. Melting of permafrost in the Arctic and deforestation of forests and agroforestry systems in the tropics are two such important examples. These feedbacks are poorly understood, but have the potential to alter the globe as we know it and critically test humanity's resolve for mitigation and ability to adapt.
