Watching TV Instead Of Reading

This post exists because:

sf writers comment on and extrapolate from current issues;

there was recent combox discussion of climate change (see Futures and The Relevance Of SF);

this evening, instead of reading, I watched some TV;

BBC News reported that, according to the British Met Office (see here), British weather is becoming more extreme because of human-caused climate change;

in view of this and other recent reports, both climate change and its human causation seem by now to be scientifically established?;

assessments and policy proposals have to be informed by current evidence;

sf, however futuristic, often becomes dated because of advances in scientific knowledge;

we know that Poul Anderson would have responded to new evidence but not how he would have responded.
