“...it’ll change back.”

The reason government has to get involved is because people don't "police" themselves.  Yes, climate changes over time - it always has and always will.  The problem is the extent to which people and their lifestyles hurry along the negative impacts of climate change.  Deforestation is causing climate change because there is nothing to shade the earth from the heat of the sun.  The earth warming, even only a degree, means polar caps melt sooner, water levels rise, flooding occurs, etc.  It isn't just one thing that happens - it's a series of events that may one day mean we cannot grow sufficient food to feed everyone.  But, this president, along with too many others, think that's a hoax.  

It’s a good thing we don’t need the politicians to lead on this. Govt’s screw everything up and waste our money. We must know by now we can’t nor shouldn’t depend on them. It is pitiful to me to watch these empty suits bicker and posture, and fool themselves.  

Visionaries in the private sector, like Elon Musk and others, have nonetheless moved forward on this, with or without the self-serving Trumps of the world. This post was edited by Don Barzini at November 24, 2018 7:05 AM MST

Indeed he is, Spunky. Wonderful response.
My golf buddy, a retired neurologist, calls Trump “an incandescently stupid man”. I couldn’t articulate it any better.

I watched the ‘60 Minutes‘ interview with great interest, Trump diverted and dissembled and opined delusionally, repeating his tacky little mantras ad nauseum.
Laughingstock president, closing one segment with:

“Leslie, I’m president and you’re not.” Real class act. 

I remember you and I discussing a point Trump would prove to me or not, and yep: hopelessly irredeemable. Beyond any question. This post was edited by Don Barzini at November 24, 2018 7:06 AM MST

I watched that interview, too.  That last comment was the equivalent of a 6-year old saying, "Nah, nah, nah, nah nah."  Nauseating, just nauseating.

Best answer.  History is on your side.

I couldn’t disagree more. This is unprecedented in human history. It is not on our side. 

It will 'change back' when the human race is gone.

Unlikely. Every scientist in the climate field has all but dismissed that idea. 

Re your last paragraph:

As a foreigner it's not for me to comment on his ability in administering his own nation, but seeing his lack of knowledge and experience of international affairs, he seem to want not to know or understand, either.

I like to believe we all have a right to express our opinions here.
It would be quite strange on an American, open and public site to allow freedom of expression only to American citizens.
It would imply that the USA's constitutional right to freedom of expression contained an unwritten double standard:
"It's our sole privilege to say what we like, so if you don't agree with us, please just keep shtum."

I agree that it is the most diplomatic thing to abstain from comment or be extremely careful in one's phrasing when commenting on American matters as a foreigner.
I have sometimes been taken to task here
(either for an insufficiently researched response or because the evidence, though proven, was unwelcome)
by nationalists and it is not a pleasant experience.
I find the liberals tend to be more open-minded and interested in diverse views - 'though the conservatives disagree.
Sometimes I am willing to take the risk.
I've travelled overseas and seen how others see my country from afar - and it is often an accurate perception.
Just as sometimes others can see us better than we see ourselves - I often think that the view from outside something, from a mountain or a satellite, can be very telling - as can the microscope.

I agree that from all the footage and tweets, there is no evidence to suggest that Trump cares to know or understand the science on climate change. It seems like a classic case of the head in the sand. But it's probably not as simple as that. I think that because he doesn't know the facts, he imagines that going green means a humungous loss of profits.

I think that view is mistaken. It will be far more costly to abstain from changing to carbon neutral or carbon-balance-repairing technologies.
For those who embrace the changes, there will be a technological revolution. Elon Musk will be the type to capitalise on it. There will be global shifts in employment and training, with tremendous profits for the producers of renewable power and carbon sinks.
Eventually (if the world can shift fast enough) it could lead to greater food security and healthier living.
Perhaps then Trump will realise his error. This post was edited by inky at November 24, 2018 7:17 AM MST
