***********************************
As much as a decade ago a climate symposium organized to discuss the implications of a 4 C warmer world concluded, “Less than a billion people will survive.” Here Schellnhuber is quoted <https://www.counterpunch.org/2019/08/23/earth-4c-hotter/> as saying: “At 4 C Earth’s... carrying capacity estimates are below 1 billion people.” His words were echoed by professor Kevin Anderson of the U.K.’s Tyndall Centre for Climate Change: “Only about 10 per cent of the planet’s population would survive at 4 C.”

Similarly, in May of this year, Johan Rockström, current director of the Potsdam Institute opined <https://www.theguardian.com/environment/2019/may/18/climate-crisis-heat-is-on-global-heating-four-degrees-2100-change-way-we-live> that in a 4 C warmer world: “It’s difficult to see how we could accommodate 8 billion people or even half of that....  it will be a turbulent, conflict-ridden world.” Meanwhile, greenhouse gas concentrations are still increasing.

"Right now, there is an enormously heated debate within the climate modelling community," said Earth system scientist Johan Rockstrom, director of the Potsdam Institute for Climate Impact Research.

"You have 12 or 13 models showing sensitivity which is no longer 3C, but rather 5C or 6C with a doubling of CO2," he told AFP. "What is particularly worrying is that these are not the outliers."

Models from France, the US Department of Energy, Britain's Met Office and Canada show climate sensitivity of 4.9C, 5.3C, 5.5C and 5.6C respectively, Zelinka said.

"Climate sensitivity has been in the range of 1.5C to 4.5C for more than 30 years. If it is now moving to between 3C and 7C, that would be tremendously dangerous."

Greta Thunberg boils the basics down to just 5 words: “… and it will get worse.” 
She adds that people don’t yet understand how severe the climate crisis actually is.

She can say that because she knows climate scientists have making the same point; e.g., ….


Camilo Mora: “ ….  our choices for deadly heat are now between more of it or a lot more of it.”

Michael Mann: ““A new normal makes it sound like we have arrived in a new position, and that's where we're going to be. But if we continue to burn fossil fuels ... we are going to ... get worse and worse droughts, and heat waves, and super storms, and floods, and wildfires.”

Kate Marvel: “The whole idea that everything’s going to work out isn’t really helpful because it isn’t going to work out ” said Kate Marvel a climate scientist at the NASA Goddard Institute for Space Studies. Climate change is going to worsen to a point where millions of lives, homes, and species are put at risk she said.
