I agree with you about technology, but not about sacrifice. One way or another, climate change will mean sacrifice, it will mean loss. As the pandemic has.
Governments and the public around the world have responded to Covid-19 with a combination of behaviour change and technology (vaccines).
In the USA, President Trump boasted about progress in vaccines while denying the need for anti-spread measures. Resulting in loss of life much greater than in other advanced countries.
Young climate activists like Greta Thunberg are pointing out that their generation will be the biggest losers, the biggest sacrificial victims, if governments and consumers fail to make appropriate changes.
