A new study has revealed that increased water vapour concentration in the atmosphere contributes in global warming process.
Scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science have confirmed that the increased water vapour level in the upper troposphere is a result of human activities.
Brian Soden, professor of atmospheric sciences at the UM Rosenstiel School and co-author of the study said that the study was the first to confirm that human activities had increased water vapor in the upper troposphere.
Climate models have predicted that as the climate warms from the burning of fossil fuels, the concentrations of water vapor would also increase in response to that warming, which in turn, would absorb more heat and further raise the Earth's temperature.
This study is published in the journal Proceedings of the National Academy of Sciences (PNAS).
