Laura Nielsen for Frontier Scientists Tiny particles suspended in the air, present in the air we breathe and in the highest reaches of the atmosphere, are called aerosols. And those aerosols, though relatively short-lived, have a huge impact on global climate change. In fact, much of the atmospheric warming observed since 1976 in the Arctic, […]

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. The study was performed by members of the “2K Network” of the International Geosphere Biosphere Program (IGBP) Past Global Changes […]
