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→
Audiences deserted Rupert Murdoch’s News Corp mastheads in 2019 with its tabloid tub-thumper The Daily Telegraph losing a massive 15.5 per cent of its readership across both print and digital editions, according to research house Roy Morgan.
Where I ended up after a series of happenings as described below, is concluding that we need a paradigm shift in our climate change aspirations. Instead of trying to limit warming to a point where we can avoid dangerous climate change, we need to recognize that we’ve already gone too far, that the climate is already dangerous, so we should aim to ratchet down GHG concentrations in the atmosphere to attain a safe climate.

In 1999 NASA lost its $125-million Mars Climate Orbiter because spacecraft engineers failed to convert from Imperial to metric measurements when exchanging vital data before the craft was launched. Numbers are important!
Back in 2003 a heatwave centred in France killed over 70,000 people. Another which struck Moscow in 2010 killed 10,000. During the 2009 Black Saturday bushfires in Victoria 173 people tragically lost their lives from the fire. However, health authorities believe Victoria’s record-breaking heatwave may have contributed to the deaths of about another 374 people with the state’s death toll 62% higher than at same time in the previous year.
Patrick Brown of Stanford University in California, working with Ken Caldeira, has found that the planet will warm 10 to 20 per cent more than previously thought. Here is the critical graph from their research:
On Monday and Tuesday this week we are going to have the AFR national Energy Summit in Sydney with everyone there, including Josh, Jay, Bill, Andrew Vesey and a different Malcolm Roberts (Chief Executive, APPEA). Should be fun.
the causes identified by Prime Minister Malcolm Turnbull – or unofficial backbench energy spokesman Tony Abbott – are not the same as the causes power industry experts and regulators highlight.Continue reading Climate clippings 117→
