Climate change poses an existential threat to humanity. It is now indisputable that the primary cause of this threat is human activity resulting in high greenhouse gas (GHG) emissions, which began during the Industrial Revolution and have continued to rapidly accelerate. The first warnings of impending and irreversible climate change were sounded decades ago, when governmental and intergovernmental policy makers had sufficient time to enact the changes needed to avoid the dire situation we find ourselves in today.

气候变化对人类的生存构成威胁。现在无可争议的是，这一威胁的主要原因是人类活动造成的温室气体（GHG）高排放，这种排放始于工业革命时期，并持续迅速加速。关于即将发生且不可逆转的气候变化的第一个警告是在几十年前发出的，当时政府和政府间政策制定者有足够的时间来实施必要的变革，以避免我们今天面临的严峻局面。
