It brought deadly and historic rains to parts of India and Vermont, and raging wildfires that delivered dangerous air to parts of the United States and Canada - all the sort of calamities that researchers have long predicted as the planet heats up. Protracted heat waves that enveloped parts of North America and Europe during July would have been "virtually impossible" without the fingerprint of climate change, researchers found.
