The fundamental problem with the Paris Agreement is that it has no teeth at all. It relies entirely on countries choosing to cut their own emissions, with no penalty if they fail. It is very easy for a government to make a long-term promise, knowing that different politicians will be in charge by the time any reckoning is due. One only has to look at the 1992 Rio Convention on Biological Diversity, which was signed by almost exactly the same group of 196 governments as signed the Paris Agreement. In the Rio Convention our governments promised to halt the loss of global biodiversity by 2020. In reality, the period 1992 to 2020 has seen the greatest loss of global biodiversity for at least 65 million years. We cannot rely on the empty promises of our governments to save our planet.
