Dave Borlace, noted as best "explainer" in my "Updated Best Practices for Climate Crisis," posted a helpful video on 1/27/21 Is it too late to avoid 1.5 degrees Celsius of warming?. His video notes on 1/8/21 "the European Copernicus Climate Change Service (C3S) published a climate update [ . . . . ]." Borlace says we may reach 1.5 C above the year 1850 baseline "as early as the 2030s, and almost certainly no later than the 2050s." This fits the IPCC (Intergovernmental Panel on Climate Change) post Why are we talking about 1.5°C? noting "If the current warming rate continues, the world would reach human-induced global warming of 1.5°C around 2040."
In my post Two Charts Showing What 2 C, 3 C, 4 C, and 5 C Mean [ . . . . ], I wrote the "IPCC report noted 'Coral reefs, for example, are projected to decline by a further 70–90% at 1.5°C (high confidence) with larger losses (>99%) at 2°C (very high confidence).' I have seen pushback claiming humanity is not in a climate crisis, but tell that to the estimated 500 million to 1 billion people depending on those coral reefs for food and/or jobs that will clearly be lost unless some miracle science, not yet invented, saves them."
Police officers and dancers in "Updated Best Practices for Climate Crisis" received increased Web traffic on my site which they deserve.
