Temperature pushes Great Barrier Reef to tipping point

In this post we find that the 2020 global average surface temperature was 1.25°C hotter than pre-industrial, equal first with 2016, according to The European Copernicus Climate Change Service. This is important for the Great Barrier Reef, because in a little known report in 2013 scientists found that 1.2°C is the warmest compatible with the Reef remaining a coral-dominated system. Focus recently has been on the emergence of annual severe bleaching (ASB) when the affected reefs are effectively dead. Climate change action of the type we are engaged in will only delay the emergence of ASB on average from about 2034 to 2045. Continue reading Temperature pushes Great Barrier Reef to tipping point
