It is fair to say that for people who care passionately about tackling climate change, they feel a lot more positive about achieving that goal than they did, let s say, ten years ago.
Climate optimism due to technological advances
Most of that optimism is due to the advance in clean energy and clean technologies and solutions.
To name just a few, solar power whose efficiency increases year by year; and the technological advances in battery technology which, combined with technological advances in electric vehicles, have propelled them to such a level deemed unimaginable ten years ago.
And in the near future energy storage, electrification of aeroplanes and new innovative transport technologies, such as the Hyperloop One, are critically important for us to be able to combat the climate crisis.
There are serious issues we need to overcome but where we lack technological solutions; and we must not simply hope and expect that a future technological breakthrough will find a solution.
