New insights: global warming drivers in the 20th century and beyond
Laura Nielsen for Frontier Scientists Researchers have combed through the last 2,000 years of climate records. Their assessment affirms that a persistent long-term cooling trend concluded in the late 19th century, reversed by global warming.
