…is not to panic. Don’t do it… for the children.
The Extinction Rebellion death cult and the Green Ordeal climate-doom-mongers are attempting to instill existential fear in your children in order to influence you. And they aren’t above abusing vulnerable children like Greta Thunberg.
Here’s a non-hysterical look at what we know. And what we don’t.
Climate ‘limits’ and timelines
-Dr. Judith Curry
“Bottom line is that these timelines are meaningless. While we have confidence in the sign of the temperature change, we have no idea what its magnitude will turn out to be. Apart from uncertainties in emissions and the Earth’s carbon cycle, we are still facing a factor of 3 or more uncertainty in the sensitivity of the Earth’s climate to CO2, and we have no idea how natural climate variability (solar, volcanoes, ocean oscillations) will play out in the 21st century. And even if we did have significant confidence in the amount of global warming, we still don’t have much of a handle on how this will change extreme weather events. With regards to species and ecosystems, land use and exploitation is a far bigger issue.
Cleaner sources of energy have several different threads of justification, but thinking that sending CO2 emissions to zero by 2050 or whenever is going to improve the weather and the environment by 2100 is a pipe dream. If such reductions come at the expense of economic development, then vulnerability to extreme weather events will increase.”
Dr. Curry is a valuable resource if you are interested in climate science, and a valiant defender of free speech and the scientific method.
Her Week in review – science edition feature is an excellent curated overview of, well, what it says. An example.
Curry’s post includes this nice summary quote from Larry Kummer on the IPCC’s Special Report “Global Warming of 1.5°C”
“There is nothing in this Special Report justifying belief that the world will end, that the world will burn, or that humanity will go extinct. It has been misrepresented just as past reports have been (e.g., the 4th US National Climate Assessment). The disasters described the Climate Emergency and Extinction Rebellion activists are those of RCP8.5, the worst-case scenario in the IPCC’s Fifth Assessment report – or even beyond it. RCP8.5 is, as a worst-case scenario should be, a horrific but not apocalyptic future that is improbable or impossible.”
