"Currently orbital conditions are suitable to trigger the next glacial inception. We’re due another ice age. However, as pointed out in a recent study in Nature, there’s now so much carbon in the atmosphere the likelihood of this occurring is massively reduced over the next 100,000 years."
Back in the 60s/70s the prospect of another ice age was a concern. That was before global warming research became a global industry.
Once in a while it's worth considering the reality of maintaining a status quo indefinitely and the alternatives of x metres of sea level rise vs y kilometres of ice.
