It is not politically opportunistic to raise this issue now. Instead we have a moral duty not to accept the attempted conspiracy of silence imposed by powerful political and business interests opposed to any reduction in the use of fossil fuels. We owe this to the people of Texas as much to those of Bangladesh and India, and Niger — which was also struck by disastrous flooding this week.
Climate disasters demonstrate our collective humanity and interdependence. We have to help each other out — in the short term by saving lives and in the longer term by cutting greenhouse gases and enhancing resilience, especially in developing countries.
