I give more weight to professionals who actually study this: https://www.msn.com/en-us/news/techn...cid=spartanntp

...Global climate change sits atop the new letter's list of planetary threats. Global average temperatures have risen by more than half a degree Celsius since 1992, and annual carbon dioxide emissions have increased by 62 percent.
But it's far from the only problem people face. Access to fresh water has declined, as has the amount of forestland and the number of wild-caught fish (a marker of the health of global fisheries). The number of ocean dead zones has increased. The human population grew by a whopping 2 billion, while the populations of all other mammals, reptiles, amphibians and fish have declined by nearly 30 percent.
The lone bright spot exists way up in the stratosphere, where the hole in the planet's protective ozone layer has shrunk to its smallest size since 1988. Scientists credit that progress to the phasing out of chlorofluorocarbons — chemicals once used in refrigerators, air conditioners and aerosol cans that trigger reactions in the atmosphere to break down ozone.
“The rapid global decline in ozone depleting substances shows that we can make positive change when we act decisively,” the letter says...

The size of the hole will fluctuate with the season... and yes, we have seen big 'uns, but this:
The loss of ozone has levelled off. Recovery IS happening. But slowly.
CFCs is bad for them ozones. And we don't exactly CFCs to survive. So it was an easy sacrifice.
We can't stop climate change. Not at all. And even knowing what's causing the warming trend, we can't stop that, either. Not even if we dedicated our entire economic output to sequestering carbon.
But we can mitigate the change. Even if only by a bit.
Even more importantly, we can prepare ourselves for the aftereffects.

That's not what I said.
We know that we humans are causing climate change at this time - and by definition, we know how to stop what we are doing that is causing it.

I hear that leftists don't have a sense of humor. Are you a leftist?
Whoosh goes the joke*.
Who wouldn't concede anthropogenic forcing of the climate dynamic? Where I fall of the pumpkin cart is the elevating of it above Solar forcing.
The Solar system as a whole is exiting a dust cloud into a VOID. What might the [literal] fallout from that be?
*We can't not.

Well good thing less than 20% of registered voters think man made global warming is a problem and we should do something about it.
Those are old numbers at the hight of man made global warming mass hysteria, around 2008 to 2010.
It's even less now.

It's inconvenient to care about the planet.
.
Humans are delusional due to the genetically entrenched reward sub routines in the brain which developed through natural selection over 200,000 years to be successful as hunter/ gatherers. We make irrational decisions to consume all available resources and expand to fill every available niche with no concept of the consequences in deep time.
.
Comanding modern technology to transmute 500 Million years of stored fossil solar energy into supernormal stimuli for a stone age brain.
.
One day soon we must all become sapient.
.
Much of what has already been cast in place is irreversible in a time scale of 100,000 years. Humans have set in motion the sixth mass extinction.

Why then do hunter gathering societies typically regulate their population to a steady number over centuries.
And no it’s not the “environment “ that does it.

Stone age populations and even civilized agro nations were absolutely governed by accessibility to resources which they were forced to use at the natural rate of solar flows. Population was very steady up to the discovery of fossil fuel at which point it spiked.
