Censored! Climate skepticism "violates community standards", says Facebook
How do I know? I found out when I tried to put up the post immediately below on my Facebook page. In the post I originally gave a link to a previous post of mine on Greenie Watch seven years ago. That was when I was instantly told that the post violated community standards. It was only when I deleted the link to Greenie Watch that I was allowed to put up the post.
As it happened, it didn't hold me up for long. I had the same post up on another site. So I just used the link to the second site in the post below. If you open the link you will see that site. The "banned" link is here
This should be concerning to all climate skeptics. Can we be heard?
The terrible truth of climate change
The author excerpted below, Joëlle Gergis, is a r*tbag. Only that colloquial Australian expression about rodents serves to describe her adequately. She trusts models rather than the facts. So she is of course highly regarded and highly awarded. She is in the elite of Australian climate scientists. She is a High Priest among them.
The hysterical rave below is entirely based on the output of models, models with no known predictive skill. And if you want to see how she deals with facts, see here
The only fact she mentions below is the CO2 concentration. She assumes that CO2 levels are a proxy for temperature when they clearly are not The two very rarely track one another, so an assumption that they will do so this time is heroic, to put it politely
As one of the dozen or so Australian lead authors on the United Nations Intergovernmental Panel on Climate Change’s (IPCC) sixth assessment report, currently underway, I have a deep appreciation of the speed and severity of climate change unfolding across the planet. Last year I was also appointed as one of the scientific advisers to the Climate Council, Australia’s leading independent body providing expert advice to the public on climate science and policy. In short, I am in the confronting position of being one of the few Australians who sees the terrifying reality of the climate crisis.
One common metric used to investigate the effects of global warming is known as “equilibrium climate sensitivity”, defined as the full amount of global surface warming that will eventually occur in response to a doubling of atmospheric CO2 concentrations compared to pre-industrial times. It’s sometimes referred to as the holy grail of climate science because it helps quantify the specific risks posed to human society as the planet continues to warm.
We know that CO2 concentrations have risen from pre-industrial levels of 280 parts per million (ppm) to approximately 410 ppm today, the highest recorded in at least three million years. Without major mitigation efforts, we are likely to reach 560 ppm by around 2060.
When the IPCC’s fifth assessment report was published in 2013, it estimated that such a doubling of CO2 was likely to produce warming within the range of 1.5 to 4.5°C as the Earth reaches a new equilibrium. However, preliminary estimates calculated from the latest global climate models (being used in the current IPCC assessment, due out in 2021) are far higher than with the previous generation of models. Early reports are predicting that a doubling of CO2 may in fact produce between 2.8 and 5.8°C of warming. Incredibly, at least eight of the latest models produced by leading research centres in the United States, the United Kingdom, Canada and France are showing climate sensitivity of 5°C or warmer.
The model runs aren’t all available yet, but when many of the most advanced models in the world are independently reproducing the same disturbing results, it’s hard not to worry.
To restrict warming to 2°C above pre-industrial levels, the world needs to triple its current emission reduction pledges. If that’s not bad enough, to restrict global warming to 1.5°C, global ambition needs to increase fivefold.
But these days my grief is rapidly being superseded by rage. Volcanically explosive rage. Because in the very same IPCC report that outlines the details of the impending apocalypse, the climate science community clearly stated that limiting warming to 1.5°C is geophysically possible.
Although the very foundation of human civilisation is at stake, the world is on track to seriously overshoot our UN targets. Worse still, global carbon emissions are still rising. In response, scientists are prioritising research on how the planet has responded during other warm periods in the Earth’s history.
