    BOULDER, Colo.—For almost five years, an international consortium of scientists was chasing clouds, determined to solve a problem that bedeviled climate-change forecasts for a generation: How do these wisps of water vapor affect global warming? They reworked 2.1 million lines of supercomputer code used to explore the future of climate change, adding more-intricate equations for…
