I agree about both dueling experts and that the most hysterical ones are not objective. But let me suggest this...
Say I agree with the most dire climate predictions: now what? I've used this approach dealing with several people who are emotional to the point of hysteria. I accept for the sake of argument all your science. So what?
If we do, as Greta Thunberg demands ("how dare you!"), and stop using fossil fuels tomorrow...What comes next? You've been freed!
I can tell you for one thing that millions of people will die, and it will be the most vulnerable that the caring people allegedly care about the most.
Of course, Greta has recently revealed herself as not just concerned with the environment, but also against capitalism. This is my shocked face. There is a real but not well covered split among climate activists between those who are truly trying to find alternatives, and those who would hijack the movement to achieve other, longstanding political goals. Especially their disdain for the modern industrial society we live in. (This is the problem with the Greens in Germany. They don't just hate/fear nuclear energy, they want plants decommissioned and replaced with nothing, so the country has less energy which means less industrial and yes, economic! activity.)
The reason nothing much will change about our energy sources is that we do not yet have the technology to replace fossil fuels. It's not like people aren't trying, they are numerous incentives to do so. It simply does not exist. I for one would like us to invent them, because we will eventually run out of fossil fuels, no matter the global temperature.
You can't replace something with nothing. I challenge anyone who says we need to DO SOMETHING about the climate emergency to be specific. And in that specificity, tell me exactly how much of a difference what you are proposing would make. And the negative unintended consequences.
Because that's what I think Jesus would do. 
Interesting how seldom Jesus is mentioned in this CLIMATE EMERGENCY... on a site populated overwhelmingly by Christians and clergy.
Maybe the emergency is actually denying Christ - whether radically or through the slow creep of "accomodationalism" (see other thread).
As to the consequences of the sky is falling without either empathy or genuine solutions that the experts and elites provide, all almost totally void of Christ, how is the allegedly required reduction of population from the reported eight billion to a sustainable total planned to take place.
We have seen the solutions imposed by central control governments in the past to reduce their perceived population problems:
- The Soviet starvation of Ukraine;
- The Marxist starvation in Ethiopia;
- The Marxist genocide in Cambodia;
- The Marxist cleansings in Maoist China;
- The ethnic genocides in tribal Rwanda, Socialist Germany and Central Europe, Uighar China;
- The religious genocides recently and/or still underway in Iraq and Sub-Saharan Africa.
The list goes on - rational humanist solutions to people who just won't go away or use resources coveted by the experts and elites.
History sure echoes...
