The Guardian’s environment editor John Vidal:
We don’t yet know the death toll or damage done, but we do know that the strength of tropical storms such as Haiyan (Yolanda) or Bopha is linked to sea temperature. As the oceans warm with climate change, there is extra energy in the system. Storms may not be increasing in frequency but Pacific ocean waters are warming faster than expected, and there is a broad scientific consensus that typhoons are now increasing in strength.
Typhoon Haiyan, like Bopha, will be seen widely in developing countries as a taste of what is to come, along with rising sea levels and water shortages. But what alarms the governments of vulnerable countries the most is that they believe rich countries have lost the political will to address climate change at the speed needed to avoid catastrophic change in years to come.
From being top of the global political agenda just four years ago, climate change is now barely mentioned by the political elites in London or Washington, Tokyo or Paris. Australia is not even sending a junior minister to Warsaw.
