Humanity is on thin ice—and that ice is melting fast. Our world needs climate action on all fronts—everything, everywhere, all at once. As today’s report of the Intergovernmental Panel on Climate Change (IPCC) details, humans are responsible for virtually all global heating over the last 200 years.
The rate of temperature rise in the last half century is the highest in 2,000 years. Concentrations of carbon dioxide are at their highest in at least 2 million years. The climate time-bomb is ticking.
