Climate and Humans: The Real Threats

Climate and Humans: The Real Threats

Despite geological and anthropological evidence of natural climate change throughout Earth history, we are obsessed with human-induced climate change. We spend billions of dollars attempting to reduce global temperatures by levels less than those experienced naturally in the past. We don’t consider the catastrophic effects of global cooling, with return to Ice Age conditions causing mass migrations that would make the current refugee crisis look like a picnic.

Global warming has recently morphed to include all extreme weather events, including the so-called “hundred year events”, which are part of normal Earth cycles. What is clear is that we, through an unprecedented global population explosion, enhance disasters by ignoring environmental dangers: building cities on flood plains and tourist resorts at sea level: cutting down forests on steep slopes, etc. We should be much more concerned about mitigating these human-enhanced disasters during natural climatic events than arrogantly believing that we can control the climate.

Our biggest threats are other natural phenomena, such as super-volcano eruptions and giant solar flares, which could cause nuclear winters or a digital apocalypse and totally disrupt the fragile global food chain which has replaced the robust self-sufficient one of the past.
