Scientist who sounded climate alarm in 80s, has another warning

A recent study led by US scientist James Hansen suggests that global warming is happening faster than previously thought, and a critical temperature limit could be crossed within the next decade. The research reveals that the Earth's climate is more responsive to human activities than previously understood, meaning that a “dangerous” burst of heating will be unleashed which could lead to a significant increase in global temperatures, with the world becoming 1.5°C hotter than what it was within the 2020s and 2°C hotter by 2050.
