It is time for humanity to grow up on climate change, Boris Johnson is expected to say in a speech to the United Nations in New York shortly.
The world is approaching a "critical turning point" and countries must finally take responsibility for the destruction we are inflicting on the planet and ourselves, he will say.
His speech comes ahead of the COP26 climate summit in Glasgow in November.
The PM has used his US visit to push leaders for action on climate change.
Some 100 world leaders are expected to attend the meeting at the UN General Assembly.
Mr Johnson will attempt to strike a humorous note in his speech, saying Kermit the Frog had been wrong when he sang It's Not Easy Bein' Green.
There are also expected to be references to Sophocles, the writer of ancient Greek tragedies.
According to the speech released to the media in advance, Mr Johnson will say: "If you imagine [a] million years as the lifespan of an individual human being - about 80 years - then we are now sweet 16.
"We have come to that fateful age when we know roughly how to drive and we know how to unlock the drinks cabinet and to engage in all sorts of activity that is not only potentially embarrassing but also terminal.
"In the words of the Oxford philosopher Toby Ord 'we are just old enough to get ourselves into serious trouble'", he will add.
Amid the metaphors, the prime minister will make a series of calls for action to the general assembly members, including:
- to restrain the rise in temperature to 1.5 degrees
- to pledge collectively to achieve carbon neutrality - net zero - by the middle of the century
- all countries to step up and commit to very substantial carbon reductions by 2030, in particular with coal, cars, cash and trees
- the developing world to end the use of coal power by 2040 and the developed world to do so by 2030
- China to phase out the domestic use of coal
- only zero-emission vehicles to be on sale across the world by 2040
- every country to cut carbon by 68%
- to halt and reverse the loss of trees and biodiversity by 2030
- all nations to follow the example of Pakistan which has pledged to plant 10 billion trees
- governments to work with financial institutions - the IMF and the World Bank - to leverage trillions of dollars in the private sector
'We missed our cue'
The prime minister will conclude his speech with a plea for leaders to do right by the next generations.
"If we keep on the current track then the temperatures will go up by 2.7 degrees or more by the end of the century.
"And never mind what that will do to the ice floes: we will see desertification, drought, crop failure, and mass movements of humanity on a scale not seen before, not because of some unforeseen natural event or disaster but because of us, because of what we are doing now," he will say.
"And our grandchildren will know that we are the culprits and that we were warned and they will know that it was this generation that came centre stage to speak and act on behalf of posterity and that we missed our cue and they will ask what kind of people we were to be so selfish and so short sighted."
At Cop26, leaders from 196 countries will be asked to agree action to limit climate change and its effects, like rising sea levels and extreme weather.
A recent report from UN scientists warned that global temperatures have risen faster since 1970 than at any point in the past 2,000 years.
