New study reveals the role of water vapour in climate change

# A groundbreaking research study by scientists William van Wijngaarden and William Happer has explored the significant contribution of water vapour to climate change. Their paper delves into the decrease in water vapour with altitude and emphasises the concept of saturation in the atmosphere. The researchers contend that these factors have been largely overlooked in discussions about greenhouse gases and climate change. They argue that water vapour, with its buoyancy and role in heat transfer through convection, is the most crucial greenhouse gas in the troposphere.
