I sincerely appreciate the author of this article (Olivia Alperstein) for reminding her readers of our desperate situation and our urgent timeframe and need for action – but I regretfully feel that her hope is pollyanna-ish, and therefore, that her words are too gentle. (I think she is probably a very sweet-natured person.)
But tragically, given how hard and far the U.S. corporate-state (and many of the world’s corporate-states) have moved to the right in the last 50+ years – and given how little has been done to stop global warming in the past 50+ years – I think there is absolutely no chance that worldwide governments will act effectively together “in a WWII-level effort” to keep global temperature rise below 1.5 degrees Celsius.
The selfish, greedy, sociopathic, and obsessive-compulsive corporate-state mis-leaders (and profiteers) are not going to radically change “business as usual” until environmental, political, economic, and social conditions become unbearable. (Like when the costs of hurricanes and floods run up into trillions of dollars – or when large parts of, say, Miami and New York City are under water!)
Likewise, the common people are not going to give up their cars, electricity-use levels, eating of meat, and other lifestyle behaviors – or radically pressure their corporate-states to stop global warming – until the harmful effects and losses from climate changes are felt to be painfully unbearable.
In short, for many reasons, human nature resists radical changes until it is too painful not to change!
And even then, many people still aren’t able or willing to change! They just keep doing what they like, and accept the harmful results! (For example, cancer patients who don’t stop smoking cigarettes and heart attack patients who don’t stop eating fatty foods and diabetic patients who don’t stop eating high-sugar foods, etc.)
Therefore, I think the best we can realistically “hope” for is for mis-leaders and common people to start making radical changes to our current way of living to stop global warming after conditions get terribly harmful and unbearably painful – and then to LIMIT the worsening damage, as much as possible.
I’m afraid that the realistic “hope” is that although humans will most likely severely harm the life-supporting environment (and will likely cause millions of people to die (and will likely cause million of other species to die or even go extinct!) – humans might be able to preserve human civilization and prevent total extinction of all life on Earth.
