    About Sierra Club

Why join the 1.5 Challenge? The UN's 2018 report stated we must keep temperature increases under 1.5 degrees Celsius to avert the most devastating effects of the climate crisis.

At the time, experts said that we could reach this threshold by 2030, but recent reports from the World Meteorological Organization suggest it could happen as early as 2024.
