A new study indicates that human activities may have already caused 1.5 degrees Celsius of global warming if calculated from a baseline predating the Industrial Revolution. This analysis, led by researchers from institutions like Lancaster University, UK, suggests that the Earth could be closer to the Paris Agreement’s temperature target than previously believed. The Paris Agreement, an international climate pact, seeks to limit global temperature rise to 1.5 degrees Celsius above pre-industrial levels to avert severe climate impacts.
