The Chinese philosopher Lao Tzu is reputed to have said: “If you do not change direction, you may end up where you are heading.”
This sums up the problem we face from human-caused climate change.
A “climate scoreboard” published by Climateinteractive.org calculates the impact of the current commitments by the world’s governments to cut carbon emissions.
It estimates that if the promised emissions cuts are carried out in full, the earth would still warm by about 4°C by 2100 — far above the maximum warming of 1.5°C needed to maintain a safe planet.
